Toyota was resting on their laurels with the Hybrid. Toyota is the king of Hybrids. They were caught napping along with the rest of legacy. Giving EV's lip service but finding out by 2019 that Tesla is able to make them viable and when the Plandemic and supply system became paralyzed as most of Legacy auto is far from being vertically integrated, Toyota was frozen. By 2022 and the opening of Giga Texas and the first Model Y's rolled off. Toyota tore one down and declared it a "Work of Art". The grandson of the company either was forced or chose to step down. Any talk about "EV KILLER or TESLA KILLER" needs to stop. The game is over.

Look at the efficiency factor! Whether they produce the hydrogen or electricity by wind, nuclear or geothermal, they can deliver three times the amount of power to BEVs.

Toyota and Yamaha collaboration goes way back. They worked together on the LFA and if I'm not mistaken the 1JZ. They've always innovated and looked into new technologies before inception in the larger market (looking back at the Prius). I think they may use this as an option for gearheads who like working on their cars, people who like the sounds and feel of a vehicle, etc have an option, rather than just buying another EV. It might also allow for kits to be produced that convert current gas cars into hydrogen fueled cars tapping into another market.

The process to install hydrogen tanks instead of petrol or diesel tanks, isn't any different, just different hoses and connections. We already have the means to start building these tomorrow as the jobs are already there to start installing them. Hydrogen tanks also wouldn't have to be buried which would make installation faster, cheaper and easier.

That's true with any new technology, they need enough capital spent to drive more innovation. Look at the touch screen, it was invented in like the 1960's. It took 40 years until Apple to use it for the iPhone, and it blew up from there. Now all smart phone and tablets use it, along with some laptop/computer screens.

Nah. If hydrogen is used widely as a fuel, hydrogen engines will be few and far between. You just can’t get good range if you’re burning it. Fuel cells barely work as it is, but engines are half as efficient (or worse).

They use electricity to make the hydrogen. And to save money most would just hook up your hydrogen generator to the grid with no thought put into where the electricity came from. And the final nail is that because hydrogen is so inefficient you wind up using more electricity to do the same amount of work. All this to make sure some fat old oil exec has a soft landing when governments start banning burning fossil fuels.

There are 3 ways to produce hydrogen; blue, red, green. In blue, natural gas is used, for red its the nuclear power and for green its the electricity from renewables. I won’t even talk about option blue as its not sustainable. In the other 2 cases, its more efficient to use the electricity produced to charge batteries then turn it to mechanical motion, rather than generate electricity -> create hydrogen -> compress hydrogen -> transfer hydrogen with a truck -> turn hydrogen back into electricity -> electricity into motion. In the case of electric cars; produce electricity-> transfer it using wires (mostly existing networks) -> charge batteries -> electricity into motion. Each conversion of one type of energy to another loses efficiency.

Combustion engines that burn hydrogen exists since the 70s. Mercedes played around with it back then. And BMW did in the 90s and early 2000s.

The introduction of battery/motor also enables regenerative braking. Pure ICE loses a lot of energy in waste heat (which needs to be managed) but what does get turned into kinetic energy is gone forever only to be turned into moving air or hot brakes. Also to your point, ICEs are used only for charging and not supplemental torque they’re basically generators on wheels. They can be optimized to run very efficiently at a narrow operating range vs any drive motor that operates over a wide domain of RPM, load and “throttle” settings. Every parameter from intake/exhaust cross sectional area, ignition and spark timing, cooling, lubrication, engine balance, etc can be optimized for a narrow and constant RPM range. You don’t have the muscle car that sings at high RPM/load but can barely idle and guzzles gas everywhere vs the anemic daily driver that sips gas, idles smoothly, cools easily but noses over at 5k.

One thing I really like about H2 is how well it pairs with renewables. The sun shines and the wind blows even when the energy provider doesn't win the contract to power the grid. All this free energy could be used to make H2. It could also be done by employing a smart grid for EVs, whereby people choose to buy/sell electricity to their plugged-in EV depending on market price. But this could be a harder lift to implement than installing all new H2 infrastructure, because you'd have to get the PUC to comply.

Generally we waste a lot of energy balancing the grid. But those losses usually come from "load following" types of generation.

Yes, and the two biggest shortcomings are poor efficiency and NOₓ emissions. The efficiency of all internal combustion vehicles is horrible -- can't get around the physics of combustion. Jason at his Engineering Explained channel white-boarded the hydrogen combustion engine and showed a massive hydrogen tank is needed to match the standard EV 200+ mile range nowadays due to internal combustion hydrogen's terrible efficiency. Our atmosphere is 78% nitrogen. So _any_ high temperature combustion in our nitrogen rich atmosphere makes production of toxic NOₓ unavoidable _even_ with clean hydrogen as the combustion fuel. This is also part of the issue of banning natural gas ranges in homes because of the NOₓ produced in enclosed indoor environment makes it all the more dangerous.

Meanwhile, evidence has been produced that showcases a ton of the pollution BEVs produce from their manufacturing to their disposal. I personally think the hard push for BEVs is because of the stranglehold China has on much of the world with their control of rare-earth mineral mines. Largest exporter of Lithium-Ion batteries couldnt possibly be using their position to force world governments to push for products that would make China richer. No way. The EV cult just traded their Saudi masters for their Chinese masters.

I recall, what we call here the RAC or AA, in Germany saying you'd have to do in the order of 160k kms in an EV to undo the enviro damage done building the vehicle.

In my experience in my Model Y with temps down to around 10F, the Wh/mi runs around 300, When you look at the sub-zero fahrenheit range Wh/mi can easily run up to 350 or more. In other words, above 10F up to a 20% range loss; -10F and below, more like 40-50% loss. As long as you have charging options it's really not that big a deal. I like my Model Y as a Winter car.

But, in the video it basically said little to no maintenance. I suppose that is true if you are one that trades in your vehicles all the time. I typically drive take care of my stuff and most of mine are still going at least 20+ years, and 250k+ miles later (with original engines). In EV, that would be 2-4 battery changes depending on model and capability. In some cases, that is 1/3 the cost of the car and some that I have read about (which may not be true - the internet being what it is), said due to the placement of the batteries, replacing them is something akin to a frame-off on a classic car restoration.

Also, the likelihood of replacing every combustion car in the world with an electric will take 100 years.. but if Hydrogen works, every car becomes a 'greener' car.

Plot twist: They are not more affordable. Electric cars are already cheaper to produce than ICE cars, of course you as a customer don't notice that because why should the Manufacturers sell if for cheaper if they sell their stuff just fine at their current prices. The second thing is, that Hydrogen and eFuels are much much much more expensive. Ans that's after scaling the production. The only way they are affordable is by massive tax substitution. We are talking over 10 USD per gallon here (respectively the equivalent in kg for hydrogen)

[@Aesthention]

​@germanmosca where's your sources stating that because I have numeral from this year showing they cost 40% more to produce than an ICE. Even if they were cheaper, they're not better than ICE because while they do achieve "100%" efficiency, the power suppliers to them only achieve around 30% efficiency. We're not creating energy more effieciently, we're simply trading off who makes the energy. The only way EV's becomes cheaper, and more efficient than ICE, is when we can produce enough power from renewables, find more environmentally friendly ways of mining the materials, and ways to recycle the batteries. Current government subsidies make them as affordable as they are now. Once we hit a majority milestone, they'll shoot up in price when subsidies are removed.

As the owner of a 2008 Prius and 2012 Prius V in Ottawa, Canada, I can tell you that the transition to all-electric is not so inevitable in my area until they can solve the problem of the vehicle losing significant range in cold weather (it gets down to -25 celsius here a few times during the winter!) and the battery losing charge over time, even it it's not driven. Not to mention the problem that people who live in apartments (I'm lucky that I have a two-car garage) don't have access to chargers overnight. Basically, we'll need batteries that have the qualities of super-capacitors in terms of very fast charging, but also little to no loss of range in very cold temperatures, or when left sitting for a few days. A gasoline hybrid-electric car, by contrast, has the same amount of gas in it after several weeks. I will be holding onto my Prius' until these improvements happen, or until they simply wear out. However, at this point, both cars are still going perfectly strong.

Hi Ricki, thank you for the video! A few things: why compare the most expensive model 3 (performance) at $53k when the base model costs $40,240 before incentives (after incentives it's below $35k). This would put it square in line with the "H2 ice" you have at $40k at 07:33 . So I don't see the upfront cost advantage of H2 ice Also at 8:20 you state hydrogen fueling stations "work like gas fueling stations" - so does the pump at a gas station frequently freeze onto the opening of a gas tank like a hydrogen station, or does a gas station have a potential of the software inappropriately locking the handle of the pump onto the gas tank opening as often happens in hydrogen refueling stations? - this happens even several minutes after fueling is complete FYI. Does a gas station need 20-40 minutes to go through some kind of cycle in between cars like a hydrogen station, thus frequently forcing people to wait over an hour in long lines to actually get hydrogen even though the fill up, if it works, only takes 5 min? Do gas stations have an app that say they're working but when you get there even within 5 minutes of checking, it often isn't working? Is a hydrogen station like a gas station in that residents around it demand no usage after 11pm because it's so loud (this is the case for the hydrogen station in Hayward, CA - there maybe others -- it's a MUCH LOUDER process than gas). My experience: 1 miserable year with a honda clarity fuel cell vehicle. I've been able to get a "5 min" fill up about 1/4 -1/3 of the time. Otherwise I've had the car towed several times, once every 2-3 months, because fuel stations weren't working (even though apps said they were), or after waiting 1+ hour and having 2-4 cars in front of me the station runs out of hydrogen! My family GLADLY returned this hydrogen car and bought a model Y - we are quite happy with it:)

The last time I checked, a few weeks ago, over 30% of all hydrogen fuelling pumps in California were down, and every time I check it's about the same or worse. It doesn't help that hydrogen costs over $16/KG, so it's also a lot more expensive to operate than a BEV or even gasoline powered vehicle. And a few years ago there was an explosion in Santa Clara that shut down all of the northern California hydrogen stations and took over 6 months to recover. There are also plenty of accounts of people having problems actually getting hydrogen for their cars (see the fact that at any point 30% or more of the pumps are offline). Also, hydrogen vehicles have a limited lifetime. The hydrogen components have a mandated expiration date. And those hydrogen trucks? They can only carry 300-500KG of hydrogen, which can fill a fraction the number of vehicles as a gasoline tanker truck, making transport far less economical. I also ask you to read the sticker shown at 10:49 in the video where it says, "Do not fil after 2029/11" After that date, you are no longer allowed to fill that hydrogen vehicle. Hydrogen, especially at those high pressures, is extremely reactive. It embrittles metals and will leak through everything. So basically, after 2029/11 you need to replace the vehicle.

Excellent video, and I agree with all of it. But you forgot to mention one thing, the price of the fuel. If they can make hydrogen very cheap, efficiency doesn't matter all that much anymore. Fossil fuels were never efficient either. And now I think there is a way to make hydrogen very cheap, with thermal plasma electrolysis. Hope you check this technology out! It's from a company called Hiiroc. I really want to know more about it. They claim they can make hydrogen for a price that's 4 or 5 times less than normal electrolysis with renewables, the so called green hydrogen. They call theirs "emerald" hydrogen. Yet another new color. There's also pyrolysis. BASF is planning to make hydrogen this way. It would be great if they could that ASAP, and replace steam reforming with it. Both these technologies would be carbon negative if they use biomethane. The only byproduct is black carbon. So please take a look at this! I really want to know more about these technologies. Converting biomethane into hydrogen and black carbon, would be a good alternative to BECCS. Hydrogen production would then extract carbon from the atmosphere, while at the same time decarbonize hard to decarbonize industries. The perfect technology if you ask me, but does it work like they claim it does? What are the negatives? Can you figure that out for us please? Thanks!

Could you use an alternator in an h2 ICE to electrolyze water into h2 and o2? Then your fuel would just be water instead of storing pressurized h2

A couple key things you're glossing over, even though you're mentioning them earlier, is the lower up-front cost of the H2 engine which will lead to better adoption, and the big area that ALL of the EV's out there have being energy density. That's one of the HUGE hurdles that EV trucks are having is that by the time you get enough battery for the big vehicle and 300m range, there's no payload left. If and when we start seeing salt batteries, which are about 30% larger than LFP which are larger than Li-Ion NMC that's where physics rears it's ugly head and stomps on the technology. Toyota has been working hard in Japan to get the H2 infrastructure out there to supply these vehicles at home, but you're absolutely right that it's not going to take off here until someone says "All of out Mobil/Exxon/Arco/Chevron/Whoever stations will have H2 pumps as of $Date." Once a major supplier picks an alternative energy source, pretty much EVERYONE will go to that fuel type, be it EV, H2, or even Ethanol.

[@paulo3011]

​@@JRNipper There's a bit of a bait and switch happening when we talk about hydrogen (whether fuel cell or combustion) vs BEV. BEVs are 80-90% efficient end to end- meaning up to 90% of the electricity used to charge the vehicle from the power company gets turned into mechanical motion. Hydrogen efficiency is often discussed as tank to wheel, rather than end to end. Electrolyzing water to produce hydrogen loses 20-30% energy (electricity is used). Storing instantly incurs another 10% instant penalty. Another 30% is lost during tank to wheel conversion. The situation is even worse with hydrogen combustion as combustion is horribly inefficient 60% assuming a perfectly maintained engine. Studies have demonstrated the electricity used for this process is far more than the energy output you get from hydrogen, and you would actually use fewer KW/h if you just fed that electricity directly to a BEV. When you add the increased mechanical complexity of a fuel cell/combustion engine (more parts to maintain and that can fail) and the challenges of storing hydrogen (which increases the cost of using hydrogen), there's no good reason to use fuel cell if you are at all concerned about the electrical grid. The proof is in the pudding: hydrogen had a 10-20 year development and production head start over BEV, and BEV has overtaken it. China had (and still has) the most hydrogen fueling stations in the world, and they're dumping hydrogen for BEV. BEV has a practicality that hydrogen can't match: I can produce electricity from the roof of my house and feed it directly to my car. I can't refine hydrogen and store in my backyard without large expensive equipment and it ultimately using 2-3x the electricity I put in, you'd need a massive solar installation for electrolysis. If you ever wondered why we don't produce electricity with hydrogen, you now have your answer.

[@mysilentnoise4510]

The interesting aspect of hydrogen’s potential (for me) is the potential for decentralized (mom and pop investor) local hydrogen production. Big $ power companies are afraid of losing their monopolies. Plus, the potential to store an extra hydrogen cell (once properly designed) for emergency use (similar to an extra gas tank) is a unique advantage over EVs. Not one single EV on the market has a backup fuel source.

And the mention that there is emissions I guess they are no where near to what current solutions (beyond EV) are. Used to also be a carmechanic and would say that ICE repair costs interest me. Since the addition on more and more elctricity to our vehicles it has created the issue of not being able to do any self-repairs and Japan & Toyota (like VW) have been really big in part manufacturing and repair centered manufactory and design. Do you have any thoughts oon Gas-EV-ICE repairs?

We have a lot of ICE cars, there is less waste in converting them rather than junking them and making everybody buy new EV. We've been running ICE on gaseous fuels for a long time- butane, propane, natual gas, so there isn't that much work required to run on hydrogen. And no harmful emissions. All we have to do is find a good way to generate the hydrogen, and a way to transport it and dispense it.

[@gsyl655]

I think its important to also consider what happens to all the dead batteries from EVs. Sure there are claims that up to 92% can be recycled, but there is also energy being consumed to conduct that recycling effort - so there is energy consumption up front to build these batteries and then more at the tail end to recycle them. And will those recycled products maintain that 92% recycling rate once those products die or will that percentage keep going down? Will lithium supply last as EVs sales rise or will it become like oil and bring inflationary supply/demand issues over time? I'm glad to see Toyota pursue this effort, even if it ultimately fails. Someone has to try, as hydrogen seems to be the cleanest and most abundant fuel source. It should also keep the EV manufacturers on their toes to try and improve on their technologies. Competition in that regard can be a good thing. Perhaps hydrogen could be a better fit for commercial industry and EV/battery technology best fit for consumer vehicles and golf carts, etc.

Thank you again for a good video giving the pros and cons on EV, H2 and Hybrid H2 and EV. I have a better understanding of each now. I have a hybrid car (gas, electric), and its wonderfully bridging the gap between the tech; gas and EV. I am not sold on EV alone mainly due to the battery and how it is manufactured and the enormous amount of energy production necessary to supply to EV; so the H2 fuel cell (not the ICE H2) seems more promising to me due to cold temperature problems with EV. I think Toyota is fleshing out the issues with H2 with partnerships and spreading their research costs. Which may produce a gen 2 or 3 H2 later. Seems like (and please correct me here if I misunderstood it) the H2 might be better suited to commercial ventures like trucking companies and government vehicles. This would reduce emissions again and give our electric grid infrastructure some breathing room to ramp up for an electrified society. That said, diversity is the better course in my opinion. Having lived through blackouts I was still able to cook and draw water due to back up diesel generators (city level for water) and natural gas for cooking. I still think the nuclear option is the most viable especially with thorium and sand silo batteries (as described in your earlier videos). Thanks again and keep them coming.

But it is also important that the free market also benefits as this is good for the economy, this will only accelerate development.

@@flipadavis I do not have a lot of knowledge about this but I'm guessing your 150 mile range estimate for a hydrogen ICE is based upon the efficiency loss compared to a 300 mile range hydrogen fuel cell vehicle with a battery supplied electric motor and this may well be true. The range though could easily be doubled by adding an additional "tank" without adding a lot to the weight. Obviously, electric vehicles are more efficient, I just still can't get past the battery aspect. Batteries require a huge new amount of mining to produce, they most likely have a shorter life span than an ICE engine, they add more weight to a vehicle than an ICE engine, they aren't easily recyclable, and they suck in cold temperatures. It is a very complicated subject way past my pay grade but I still vote for hydrogen ICE if only for the vroom, vroom. Also, the driving performance of hydrogen fuel cell vehicles sucks, adding to the lack of marketability.

How well does the H2 storage tanks (both the refueling stations and vehicles) stand up to those stresses (and the cost and complexities of that) is not well known. I seem to recall from other KZbin videos on FCEVs mentioning that that the H2 storage tank degradation issue is a real concern. Not only is the tank subjected to extremely high pressures, but the material that the tank is made out of is probably subject to degradation as well because it has to resist reacting with the H2 being stored.

Besides, Sodium is going to make a huge impact on the ev and stationery storage. Theres a time and place for hydrogen where it could be used, but frankly, use it for small vehicles are already decided to be a lost case.

No one disposes of lithium batteries. They are recycled.

Plug-in hybrid is a clear winner here, and I hope more people notice this. How? By taking the pros of each system and removing the cons; you don't need to carry a heavy battery wherever you go and wait for hours to charge it, and at the same time, you don't need to use the inefficient engine all the time. Make a controller that prioritizes using energy from the battery (when available) and then switch to hydrogen or ammonia. The daily drive of most people doesn't exceed 100km; therefore, a small battery back is sufficient, and when occasionally there is a distant trip, the system will switch to hydrogen or ammonia. The problem of inefficiency here is significantly reduced, how? Because roughly let's say, for example, from 10 daily trips, 9 out of them with an energy-efficient driving of 85% and just 1 with 36% efficiency; therefore, overall efficiency is 80%. Even this is cheaper to manufacture (I didn't make cost calculations) but you need just a small battery and no need for an expensive fuel cell.

I see this for public transit. Maybe even a way to store renewable energy via h2 ice generators

[@geoffstrickler]

I don’t think it’s the long term solution, but it may be an interim solution, especially if someone commits to putting it in OTR trucks and finds a partner to provide nationwide hydrogen filling stations. It’s quick refill capability is a huge benefit for trucking, and other long-range transport. Might also be useful in shipping and/or rail transport.

[@ghollidge]

I think that we are a species we have stopped where we are because it works for us. Until we push pass where we are we'll be using ICE for awhile

[@cplai]

I disagree. It is not popular now because hydrogen delivery infrastructure is lacking and clumsy. But some recent research found a way to absorb large amount of the gas into a powder and release it on demand. Given a storage solution , hydrogen can be produced anywhere with solar panels.

[@geoffstrickler]

@@cplai doesn’t sound like you’re actually disagreeing with me.

[@cplai]

@@geoffstrickler What I meant was hydrogen can become the long term solution because better storage technologies are on the horizon. So I disagree this is only an interim solution.

[@geoffstrickler]

@@cplai Storage isn’t the main issue with hydrogen fuel, it’s separating the hydrogen from water or other sources that is very inefficient. Add in the costs of compressing and storing, and the total cycle is pretty inefficient. It’s useful, but I don’t think it’s a long-term solution.

I personally believe this is quite promising and it will fill its own niche application. We shouldn't think in terms of "either/or", but that each technology has its own particular applications that make it more suitable than others depending on the situation. We shouldn't be political, we should be practical. Thank you. 🙂

[@rogerphelps9939]

It will be an incredibly small niche and will not be relevant to you.

Very nice video 👍 Engineering Explained guy was a bit down on hydrogen power

Here in Australia for many years we have had LPG Powered cars Same idea as this option just with a different gas. The problem mainly is that H2 at the current time can only be made in great quantities and cheaply using VERY dirty ways which more than over rules the cleaner emissions burning H2 would bring about. As for refueling stations here in Australia this used to be a problem with LPG fueled cars you could get it in all main cities but not on the highways and small towns so LPG was usually only used for city driving as an example in taxi cabs. The big saving was in the cost for LPG per litre when compared to Unleaded or bact at the start leaded fuels. Right now here a litre of gasoline fuel ranges from $1.60 upto $2.00 per litre depending on what quality you want. While my LPG costs between $0.79 to $0.99 per litre and unless i am towing i still get the same milage as the gasoline car. This is in a 2003 model car with just over 100,000 miles on the clock. Later model LPG cars used the liquid gas injection like what you are describing the H2 cars will use and these dont loose range to gasoline cars when towing. Because LPG is a fossel fuel but burns at a significantly higher temp than gasoline it has less harmful emissions though still not NONE. To convert my LPG car to H2 as fuel all it would take would be to change from the old system to liquid gas injection a matter of swapping the head on the engine and installing the correct injectors to suit the H2, The remaining fuel system would meet the requirements to hold and [i[e the H2 from the tank at the rear to the engine up front. As for EVs being so clean and good for the environment most EV people that claim EV is way foward and all else will kill the planet always over look the emissions getting all the minerals that are required to make the batteries and turn them into limited life span batteries which when they die are just more toxic landfill along with the car they are in due to cost of replacing the batteries being greater than a new vehicle. Also there is the emissions created by electricity generation as there is little truely Green energy production being made as a percentage of electricity world wide. Most electricity in the world is generated by dirty means when you include Atomic energy in the dirty (due to the left overs whebn fuel rods are used up that have to be stored for so many years to make them safe). Till the electricity storage or generation can be made to happen in an affordable and clean way it is not the answer it is only a part answer neither is H2 an answer but it is a part answer the main thing is we have to get away from fossel fuels to start and to then as the cleaner ways to make electricity AND cleaner more effecient battries can be made with greater storage or fuel cells to generate electricity on the go to improve range and charging times. There is no real true clean answer but only ways to try to limit dirty emissions as much as possible, remember methane is also inclided in so called green house gasses but we are not saying to stop breeding cows or sheep etc to cut the production od methane because it would lead to bigger problems. There are better answers but we cant wait for them to be found to save the planet we have to work with what we know now and attack the problem with the best of all possible ways to remove fossel fuels so we use the cleanest possible fuels at hand at the moment. Every little bit helps. I am not a fossel fuel junky nor am i an EV or H2 fan as i see places where one vehicle would work better than another for example in medium sized cities and some of the larger ones where your travel time to and from work is not too large then an EV would work well and clean up the air in those places for longer driving such as interdtate or country driving then some form of Hybrid vehicle that produces electricity on the go would be best. and to help clean up the older vehicles that still are good vehicles you could for a reasonable amouth convert them from gasoline to run on H2 as this is mainly replacing an old tech with a new fuel. Even this sort of fitting the solution to the use of the vehicle will not cover ALL the different places the emissoms are coming from Rtucks at this time dont have a replacement for the current power train nor do planes.These rely on mostly fossel fuels or some blend of bio furls and fossel fuels. It is a long way to go to get to carbon and other green house gas neutral with luck and taking jard choices it will happen in time as we clean up our act but it has to be done without using tech that seems cleaner untill you look behind the face of the tech and see how parts of it are made and what is the waste from that. This is where the Atom was in the 1950s it was going to be CLEAN CHEAP ENERGY ofr the world but time has shown it is not CLEAN or CHEAP.

[@RAM4-pz2dw]

Making this engine flex fuel might be the next step. With a switch you move from H2 to gas and vice versa. That would make it a vary interesting option

[@gregbailey45]

The engine design constraints probably will not allow that with any reasonable degree of efficiency!

[@rogerphelps9939]

Not really. Petrol won't be available in most places and efficiency will ber abysmal. That means that it will be very expensive. You are clutching at straws.
