[@michaelharrison1093]

Matt - as a suggestion you could investigate a huge looming issue that faces all of the modular portable energy storage systems. With the fixed home energy storage systems there are many levels of safety standards and regulatory requirements. You can't just put them anywhere - usually you can put them in a garage or outside, and even then there are many other regulatory limits - the maximum size relates to the volume of the room that they are being placed in for the garage situation. These regulatory requirements are then checked by an inspector as part of the installation sign off process. Your insurance company is potentially going to decline payout if it is found that your home energy storage product was not installed to code and certainly if it was never signed off. The problem with modular portable systems is that they are able to circumvent all this installation safety inspection and sign off. Sure the manufacturer might have use instructions but there seems to be a minefield here with regard to how this all plays out once there are a few home fires started caused by these portable storage devices. For research you could look at what is the installation advice provided by each product. See what liability each of the manufacturers would be willing to cover, and what insurance companies have to think about this situation. I predict that there will come a point in time when all insurance companies will simply state that they are not responsible for payout if you have these products stored inside your home. And impose strick limits to how many you are allowed to have in your garage.

The choices for home power back up other than a Tesla Power wall got most of my attention. The other was getting rid of batteries in all of my remotes and other things around the house. Great video as always Matt. Thank you

[@drgyt2469]

Hydrogen for mobility caught my attention. Storage in high pressure tanks is however not optimal.

[@michaelharrison1093]

Hydrogen for transportation seems to have many problems - the biggest however seems to be one that many people don't even consider. The change from supporting a fossil fuel based transportation infrastructure to an EV will be a big undertaking and the viability of this new EV infrastructure benefits from capturing all of the potential transportation energy needs. Add H2 into the equation and you then have competing infrastrutures that compete for refuling station locations and for the vehicles but there is no ability for a customer to easily swap from EV to H2 or vice versa without a major investment, hence the two energy sources don't actually deliver any of the benefits normally associated with market competition. I saw this situation play out in New Zealand where I grew up. There the established vehicle fuel option were traditionally gasoline and diesel. Then in the 1980's there was a big investment to make both CNG and LPG available as alternative transportation fuels - the infrastructure cost was crazy high and at the end of rolling out all this competing infrastructure it was then realized that each fuel source ended up capturing a quarter of all the transportation vehicles. The problem was that there was clearly no clear winning fuel and the reduced useage and costs associated with maintaining 4 competing infrastructures had the result of making all options more expensive.

As a condo dweller, I’d love a deeper dive into those balcony solar panels. Love your channel! Keep it up 👍🏼

[@hannes_k5666]

As he said, in Europe these „balcony power plants“ (literal translation from german which is hilarious imo) are starting to take off. This year, Austria for example extended tax breaks that previously only applied for full-fledged rooftop solar to these balcony systems as well. The system cannot exceed 800 W though otherwise you would have to obtain approval. Now you can get 800W panels with mounting equipment and inverter for as low as round about 400 euros.

[@mb-3faze]

You could just do it. Panel, microinverter, plug it in to a socket - done.

[@__WJK__]

Unless those (balcony) panels offer some kind of advanced efficiency, I’m thinking they’re not going to be a huge hit since a lot of balconies have major shade issues/receive little to no “ideal” Sunlight. Also, one would think portable camping panels (especially the latest SIGS panels) would make a lot more sense for this application. Plus, I can see how building management would quickly want to ban these for alleged eyesore and/or liability issues :’(

[@hannes_k5666]

​@@__WJK__ I agree, obviously the balcony has to be an optimal spot to gain sunlight and also angle matters I guess. Not quite sure about camping panels though, for balcony application I guess it has to be a quite sturdy and withstand the elements if you don't want to constantly put it away and put it back out again. But I might miss something here. House management could be an issue of course. But I mean come on, a dark-ish/black panel? But yeah I can understand there is house management that has something even against that. From a liability perspective one could think of mounting an extra safety hook to the panels like the one's used in the event industry for pursuing the neighbors that safety is ensured even when the primary mount would fail.

[@nickstroke]

Would this tech. be usable in an off-grid situation? I'm curious what sort of power output it can deliver and if multiple systems can be stacked.

[@challacustica9049]

Would love to see a deeper dive into the low light solar panels as well as the process to turn sewer sludge into hydrogen.

[@AndrewBuis]

There is the obvious: Sewer Sludge = Methane. Pipe methane into a motor, ignite it -> Electricity -> Hydrogen. Similar to the methane capture from landfills. I'm guessing the news is that they have a novel way to capture and/or concentrate the methane?

[@mb-3faze]

There are so many things wrong with any sort of 'hydrogen economy' - particularly for vehicular transport. Generating hydrogen is simple (if inefficient). It's the compression, cooling, storing and transportation which makes the whole value-chain unsustainable and inefficient. These companies drone on about using green electricity to create hydrogen but fail to point out that the energy losses are huge before that bit of green energy has turned any motor. It's far better to use the green energy the instant it is generated and if that is impossible, store it in batteries which is in the 80-90% efficiency range (as opposed to 2-5% for a hydrogen cycle).

[@JakeDMaier]

The Walking Dead did it first@@AndrewBuis

[@jeremyshell]

Yes, 100% agree that this would be worth a deep dive. 👍

[@JSDV9999]

The digestion process produces hydrogen and CO2 allong with the methane. Different microbial populations can produce different proportions of the various gasses, and those populations can be altered by changing the environment or by seeding the system with specific types of microbes. The methane motor is the most reliable with our current capabilities, but you can theoretically get straight to hydrogen without much more than a bucket and any organic waste. @@AndrewBuis

Great content - take time off if you need to relax, but keep 'em coming on a schedule that works for you.

[@Unbreathless]

Would definitely be interested in hearing about Balcony Solar. I live in Eastern Canada, and the Hydrogen topic has come up a lot here lately. In Newfoundland, they have started work on a Hydrogen wind farm with a German company. Newfoundland & Labrador is an oil and gas producer, and I wonder how much of the pivot to Hydogen has to do with existing infrastructure for O&G (logistics and operations)? Incidentally, NL also has a huge amount of renewable energy, with around 96% of the province's power coming from Hydro, while selling a lot of that energy to neighbouring Quebec.

[@robine916]

That hydrogen wind farm would be a great topic for a video💕

[@hallo_welt1111]

Here in Germany, there really is a big hype about balcony solar. These things are cheap and paid off after 3-4 years - expensive electricity helps getting there faster 😉

[@hairyneil]

Could well be to do with o&g infrastructure. The first place in Scotland to start using hydrogen buses was Aberdeen (where almost all of our o&g engineering is)

[@IMGreg..]

Hydrogen is far from dead as it's a multi use medium. Batteries are not feasible in heavy equipment farming, mining, and locomotive applications also it can replace fossils in blast furnaces for steel manufacturing. Islands lacking land mass for solar can convert from diesel generators to hydrogen to produce grid scale electricity and run their cars and trucks on the one fuel as opposed to importing gas and diesel. Hydrogen is also a good energy storage medium for over production of green energy from solar, wing and ocean tides as well it is easily scalable by adding more tanks. Electrification by batteries a lone requires mining of rare commodities whereas hydrogen can be produced directly from seawater without any pretreatment processes. Every island nation could in time end or reduce their dependency on imported fuels period.

[@vindeballs1]

I have a nice South facing gable end wall which I wanted to put solar on but couldn't get MCS certified for export purposes.... so didn't go down that route... anyone else had this problem.

You're right about the low-light solar. That really could change a lot of things, and actually convince me to go wireless on mice and keyboards finally. It's the whole "i hate changing batteries" thing that has kept me from using those devices up to now.

[@jacksmith4266]

You need to change batteries every 1 to 2 years, so that's an excuse rather than solid argument

[@martymcglame7781]

And to me it's not so much the "hassle" of changing batteries, it's that one ends up with these chemical metal casings that rarely get properly recycled = more waste.

@@michaelmartin9022 Wired connections do have latency and in the case of mice and keyboards wireless can actually be faster (distance, bandwidth, and interference matter). One of the most popular gaming mice is the Logitech G502 Lightspeed which has a wireless connection that they claim has less latency than a wired one (so long as you don't have too much interference of course). I happen to have a G502 myself and I only have to recharge it maybe once every few months which isn't too bad. For things like smart sensors, smoke detectors, and remotes having to change the batteries can be far more annoying, inconvenient (if the batteries die at an inopportune time), or even dangerous (how many people regularly test and replace the batteries in smoke detectors and how often does the 9-volt get taken out to stop the annoying beep then never replaced because most people don't have extra 9V's lying around and just forget about it).

Would love to see a video on followthrough stories at CES. Not just success stories, but mistakes made as well. I feel like we're way too quick to write off missteps and challenges as outright failures without taking the adequate time to look at the lessons learned in the process, and anything to help change the discourse on that goes a long way.

[@larrywest42]

Great idea. One approach would be to look back at CES from 15 or 20 years ago and look at what burned brightly but then flamed out✻ ... and see what happened to their key concepts. Impractical? Quality issues? Badly marketed? Done better by competitors? Et cetera. ✻ "burned brightly but then flamed out" because we want to hear about something interesting. There are *lots* of putative products displayed at CES that struggle mightily to elicit a _"Meh"_ and truly aren't worth anyone's time.

Well, I think you make a great point, but multi residential housing, which is the most common city use case, whether, tall buildings, three and four-story condo developments, or other commonwalled structures, have a lot of specifics that aren’t easily covered in such generic topic videos. This is not a criticism of the videos, they bring to us, the masses, a lot of things with more depth than we would otherwise be aware of. I think this raises the tide of public awareness and interest in development of the future in mostly positive ways, especially because of so much coverage of alternative energy sources and their development and use.

[@frequentlycynical642]

Good point, but most multi-unit residences are not owned by the residents. An owner of a home can make the decision all by his or her self to do something about energy consumption. An apartment dweller can't. If the building is a condo, a majority of the unit owners would have to agree on projects. Yeah, right, they usually can't even agree on assessments to keep things going.

[@Ynhockey]

@frequentlycynical642 I think it might be true for North America (not sure tbh), but in Europe and Asia most homes are apartments owned by whoever lives in them. That still doesn't mean the owner can install stuff on the roof necessarily, or even pick specific windows, but often building residents can do things together.

[@JakeDMaier]

Batteries getting cheaper for homes is amazing! Portable ones are exciting because I can move them from one home to another easily! If I move down the line, I don't need to have as huge of a hassle! Also, I'm still poorish, so affording a $5k system is way better than a $15k initial hurdle.

[@justinstephenson9360]

The one thing I do not understand with the home battery systems is why they are so expensive in the US compared to the UK, for most things it is the other way around. A good example is I can pick up a 9.5kw home battery for about $3500 here in the UK. Fully fitted with is under $6000 and they have been stackable for a couple of years

[@ab-tf5fl]

Cheaper and lighter batteries have just so much potential. Imagine being able to run your entire house off batteries when electricity is expensive and charge the batteries a few hours later, when electricity is cheap (and have this all work automatically through software, without having to think about it). It would cut a huge amount from the home's electricity bill. Battery storage also makes rooftop solar much easier to justify, since you can use the solar energy when electricity is expensive, not at whatever particular moment your solar panels happen to be producing it.

I like the fact that home batteries are steering away from Lithium-ion and going with LiFePO4 instead. I also like that a few companies are going the modular route, so you can buy a smaller kit at first but incrementally increase the capacity over time for less than the price of a new small car.

[@TraconWizard]

Provided they don't change some parameter. "OH, sorry, the new PBX6000 isn't compatible with your unit. You'll need to upgrade."

[@southcoastinventors6583]

Because having batteries that explode in houses is not a good look and generally there is less likely for that to happen using that chemistry

[@lennyvalentin6485]

Expect to see a further lateral move onto sodium-ion cell batteries here; cheaper to make, and even safer than LiPO chemistry cells. It's been said that sodium-ion cells basically cannot catch fire at all, even if provoked, and you can drain them down to zero energy with no harm to the cell itself, for additional safety when transporting or long-term storing the unit. This is a very interesting market space right now, we can expect even more rapid product developments in years to come... :)

[@jeffs6090]

Sodium ion will be the best for the home, and will be great for phevs and smaller, non-sport vehicles

[@Cordycep1]

Lifepo4 battery has been used last 4 yrs, dont see anyone selling Lithium storage anymore for home. Main issue is cost, why does lifepo4 on a car cost $100 / KW, but the home lifepo4 cost $500 to $1000/kw. Maybe it insurance and UL cost.

The balcony solar and hydrogen developments would definitely be interesting for future videos, as they were for prior ones. I'm itching to see some of this come to market in the States. Meanwhile, I find myself extremely curious about the Orcam as a means of handling my anxiety in crowds. I tend to get overstimulated in large crowds. During the 2 years I worked in Manhattan, I used in-ear monitors to shut out all of the noise during my commute, which may be the only reason I survived that mess. These days it's gotten worse, and I can't handle loud restaurant settings or busy grocery stores. So while hearing aids may traditionally be for amplifying the world for someone hard of hearing, I yearn for an option for quieting the world back down. I look forward to finding out more.

[@fltrucker4933]

Excellent video. I enjoyed viewing it. One point you mentioned about Hydrogen that I am familiar with is in the heavy-duty trucking industry. Hydrogen is needed to replace batteries because of the weight factor. A large battery-powered tractor-trailer is at least 16,000 lbs. heavier than a comparable diesel truck. Tesler’s rigs carry potato chips, so they never reach the maximum gross weight of 80,000 lbs. In the real world, a trucker hauls close to a 50,000 lb. load. Subtract 10,000 lbs. for the trailer's weight and 17,000 for the weight of the tractor. Now add 1700 lbs for fuel and the driver with their items. The truck is around 80,000 lbs. Now add 16,000 lbs of batteries, and the truck is overweight. 😊 only solution is to take less cargo. No trucker is going to take less cargo. The latest happenings with hydrogen is a breakthrough that it can now be carried in a liquid state without having to be kept at absolute zero. A significant truck manufacturer just announced this, and the technology will be accessible to anyone to use. Also, this will allow fueling the trucks in about 10 minutes. This is why the World needs Hydrogen.

I’m very interested in apartment power and storage, solar and wind. Also, inexpensive devices that could help determine power potential; I.e., a sheet or device that could be hung up in a window for a time and measure the potential power at that point.

[@seewaage]

Thanks for keeping us abreast of changes Matt! Appreciate it!

[@maikydb]

I would love to see more about home batteries. The pro's and cons, how they are made and estimated cost for instalment to user friendliness.

[@Level1Communities]

Great info on home battery backup systems - for apartments. Very interesting.

[@aL3891_]

the high density solar cells sound really cool, would love more info on them :)

[@checker_boarder]

I took an energy storage course this summer as part of my undergrad in sustainable energy engineering where we designed a system similar to the balcony solar system, so cool to see this technology commercially available!!

[@davidgray6959]

The earbud tech is getting extremely close to the universal translator from Star Trek. Soon we will have an automated app that will translate any voice speaking to us in any language. I'm looking forward to this in the next few years. Amazing. You just showed us the directional ability of the sensors, and we're already connected to the internet translation. Only two more steps to automate the detection of who is speaking to us and cancel out the original voice, plus start the translation automatically.

[@joergmaass]

I'd love that! I often have the situation that I don't speak the language of the person I engage in conversation with, so such an universal translator would be awesome!

[@davidgray6959]

@@joergmaass Just a few more years, if that! The plug-in sensor in this video will probably be made smaller and integrated into the phone hardware so you can just set it on the table and start talking like normal without even thinking about it.

[@michaelmartin9022]

There will never be real-time translation as the person speaks, grammar alone says "no" to that! English actually has a really wierd word order, which few other languages share.

[@davidgray6959]

@@michaelmartin9022 Well, not quite as good as represented in movies, but I bet we soon get to a point with a short enough delay to engage in a relatively normal conversation. I once spoke to someone for two hours with just gestures and drawing pictures. It took a while, but it worked! Even if the app takes translation one segment at a time, we can talk like we're using one-way radios, over.

[@_DaveMadeThis]

I’d love to hear more about the follow through / progress towards sustainability!

[@GeorgeBP81]

I could definitely see H² used in marine transport as this sector uses the dirtiest type of fuel, the accidents also become disasters when it spills out. Also having H² transportation with exhaust recovery in desert regions would help in more ways than one. As far as I'm concerned, finding a way to mass produce, store and distribute green H² makes a hell of a lot more sense than batteries.

[@FlesHBoX]

Yeah, the only people saying H2 is dead is the church of Musk.

[@mischadebrouwer9855]

Not to mention steel industry, fertilizer industry, and eventually all chemical and other heavy industries. Give it ten to fifteen years, and green H2 is so abundant, that the applications in transport will grow as well.

[@southcoastinventors6583]

@@FlesHBoX Its still dead regardless of who says it because batteries do a lot better job holding on to power as oppose to Hydrogen Storage tanks and continual make incremental improvements. Plus turning solar energy into electricity is way more efficient.

[@KnarfOfSpam]

There is so much solar energy wasted because of unavailable storage. If we could solve the challenges with hydrogen generation (efficiency and transportation) there would be plenty of applications starting in industries

[@mikep7627]

The only argument against Hydrogen at this point is the round trip efficiency - meaning the energy into a battery vs delivered. H2 generation ("charging") historically is less efficient than a LIB, mainly cause of the energy needed for compressing the gas....+ added overpotentials Bipolar membranes are solving some of the RTE challenges, and I hope that more progress is made in this area. That said, we have yet to find a single bidirectional device that can compete with a lithium ion battery in terms of efficiency, and its a much more challenging system to mimic what a lithium cell can do RTE is what defines $/kWh. If we can get it below or close to a LIB, thats the key to implementation

[@ryan56976]

Sorry, i just realized i was not subbed. Been watching your stuff for a long time and really dig it. I really enjoyed this piece, was curious about some of the new tech and I’ve always appreciated your perspective. Keep it coming!

[@DJTI99]

I live in a house with solar panels on the roof, but want to hear more about balcony solar. It sounds like it would be great for a van or camper.

[@CrossWindsPat]

Best bet for that would be to rig up real solar panels onto your camper. Nothing is gonna beat the energy production of a rigid frame panel.

[@TTerribleK]

This was a refreshing video. I'd love to see more about the ambient photonics in more everydays objects as well as that balcony solar. those were some great ideas!

[@colinkulasik1128]

Im glad to see more h2 talk. I think its the automakers' way of getting around the long battery charge times. We know how to fill liquids quickly into our vehicles and h2 is a nice clean battery. Now if they would only implement onsite generation rather than shipping h2 like they do petroleum. Shoot at that rate why not make o2 burning vehicles too, when you split water you get both. Cant go putting trees out of business by just dumping the o2 as waste 😅

[@5353Jumper]

You would need around 3x more solar panels on your roof to make enough hydrogen for your car compared to charging an EV. Should we really be looking at an inefficient technology when there is an efficient one already available?

[@eran3161]

Also h2 is not a liquid at atmospheric pressure.

[@colinkulasik1128]

@@eran3161it's not at atmospheric pressure, or should I change my statement to "a fluid". Would that make you feel better?

[@TimothyBishop9547]

Yes, please do a Deep Dive on Balcony Solar! Great content all around, Thank You!

[@TexRobNC]

I feel foolish for thinking wireless power was going to be the answer to small devices needing power, this stuff is 100% going to fill that role. This stuff is going to be huge, you need to do more videos on it.

[@popps33]

Definitely interested in Balcony Solar Technology!!

Thanks for this video! I like how your interests are in environmental and sustainable technologies, and not computers like the other channels I've seen cover CES. You've got a unique and interesting perspective on the show.

[@9785633425657]

Thank you for the coverage of CES, Matt!

[@johnandmariewilliams7796]

[@AnonyVoiceGla]

Balcony solar sounds exciting. Could you please cover this in detail

[@66block84]

These things look fantastic! Thanks for sharing.

[@totalepicrandomness2]

The balcony solar is a good idea. But you shouldn’t plug in solar inverters or generators directly into outlets. The voltage will back feed to the power lines and transformers powering your house or apartment. And the voltage will actually be amplified by the transformers, that usually step down the voltage we use to 120V. It will feed the lines with 7,000V which is very dangerous for linemen working to restore power to your house in an outage. It can be done if you are able to disconnect your electric connection to the grid at the breaker panel, but I feel like most users of this product will forget.

[@seeitwithchris1041]

This was a really exciting video. All the items you brought up were all interesting. Best CES related video i've seen yet. Thanks! I'd suggest also checking out the Rabbit R1 device too.

[@asparra]

Thanks man I really like your videos very informative and I love the enthusiasm

[@maxwellomdal9178]

I would love to see more about balcony solar!

[@sr91131]

Like to hear more about Balcony Solar.

[@aarondus]

Great recap of CES 2024. A deep dive into balcony solar would be amazing. And while on the topic of solar, I’m keen to hear your POV on solar sheets vs solar roofing tiles. They look nicer but are they as efficient. Thanks for considering the deep dive. Keep up the great work on your videos. Hands down one of my favorite channels on YT.

[@yay-cat]

The headphones - it’s a great idea for schools. I work in acoustics and you try to spec a suitable amount of absorption so the room isn’t too reverberant because kids struggle with comprehension and concentration in reverberant spaces. But then neurodiverse kids need more absorption/ less reverberation that other kids but besides the cost of all the acoustic products; if a room is too dead the teachers get vocal strain. So having devices where you can only hear the person you want or or group of people you’re talking to in a crowd could be phenomenal. I can’t hear properly in restaurants because I struggle to tune out other noise and because the spaces are often very echoic so it’s not nice and isolating going out (alcohol obvs makes this worse). I guess it could also be useful for that rabbit AI thing if it could whisper some extra info to you in a meeting

[@Goldenah]

Really glad to see power backups for the entire house become cheaper, simpler and easier (for someone like me) to understand and setup. On occasion we have blackouts, especially during storms, that last minutes to hours and these will definitely come in handy.

[@manikantagadde4181]

Great summarization Matt. Would love to hear more on balcony solar panels.

[@crunchysteve]

At 7:45, I saw a brand that, coincidentally, is on the back wall of my house. GroWatt, the makers of the inverter in my brand new, less than a month old rooftop solar installation! I am chuffed with this whole system, so seeing GroWatt made me check today's energy generation. Another 24kWh 😁

[@JKarle]

Yes please! A deep dive into those new high density solar cells and the balcony solar set ups

[@waynemcintoshjr5030]

You got a new Subscriber with that Balcony Solar System/technology. I’m interested in learning more and so far this video has been very informative and straightforward.

[@jacksmith4266]

Combination of the solar panel on devices and the upcoming EU regulation which requires devices to have access for customers to change the battery easily is a game changer

[@itinsuranceguy]

Matt, getting rid of those AA and AAA batteries would be fantastic. Please do a deep dive on that one. P.S. sorry to hear about your burnout. I hope making these videos continues to fulfil you as much as we all enjoy and look forward to them. Cheers!

[@drwho8576]

You mentioned it briefly, but from swage to hydrogen? that would be really interesting for a deep dive. You have one of the best channels in all KZbin. Thanks for all the work you put on this.

[@TravisMurdock]

I'd love to better understand how porch solar allows you to power your house/apartment by plugging into a regular wall outlet. I didn't think that you could power your house/apartment by just pushing power into a plug. I'd love to hear more about that because it would allow many more people to put in small scale emergency power systems into their house without electrical wiring.

[@GoldRoks322]

I like the idea of hydrogen vehicles better than the EVs. Also please do a deep dive on the apartment solar options

[@joedance14]

More on Ambient Photonics, and low light solar in general, please. Also, more on hydrogen - and other alternatives to lithium for home energy storage. Thank-you. Stay well and stay safe!

Why stop at balconies? Use them for window blinds. The entire NYC skyline using this technology that was envisioned in anime would easily put a good dent in power issues.

[@quinn7864]

Solar that goes beyond just the standard panels that get installed on a roof would be great. So the balcony solar panels would be interesting to learn more about. As well as any other unique solar solutions. I also wanted to say you do a great job of breaking down complex and technical information, concepts, etc and presenting them in a way that is easy to digest. Thank you for your content!
