Excellent effort

It is just a plain lie that one shaded panels brings the whole string down to the performance of that one shaded panel.... Modern solar panels have bypass diodes, normally 3. Numerous real life test have been performed between string and micro inverters and the consensus is that it only brings max 3% increase. What people seem to be blind for is that both micro and string inverters are external to the solar panel, so the limiting factor is always what the solar panel can produce. Technically with a shaded panel with bypass diodes it can be that there are 2 (or more) maximum power points to be found, where ofc only 1 is the highest. String inverter will fail to find the best mpp of that shaded panel, going for the average mpp of the panels in the string. So the difference in performance is really not so big as this person says. Think for yourself: is al the additional costs for micro inverters worth it? System costs of micro-inverter vs string are considerable more. Currently in Netherlands a 400W panel costs 80EUR and a microinverter also 80EUR.. For simplicity say you do 12 panels, resulting in 960 euro costs for micro (also you need some hub devices costing between 200-350 euro), compare that to a 600euro string inverter, it is clear that I am not paying almost double for the panels+inverter micro components vs the string approach. I rather add 2 more panels of 80eur/piece to the string inverter to overcome the performance gap of 3%..... So my advise is for people watching this video: google for "real-life test between micro-inverter and string inverter"

niáce anothrer PTFE aka devil pis source no thx..

Very good and detailed information given thanks

Great video

Can you use solar panel optimisers in offgrid system? I have 4kw panels feeding 24v into Victron 150/100 mppt, into AGM battery bank then into 3000w low frequency inverter. I have a mix of different panels and want to stop the lowest producing panel drag down the rest of array with it. Cheers

This sounds like a scam. The functioning of ac dosenot require heating. The compressor just compress the vapor back into liquid and this process results into a hot compressed refrigerant, post that it goes to the condenser for the temperature drop then to the valve where it is relived from high pressure to low pressure then to evaporator where the air from room passes over the coil and heat exchange happens and you get cold air. This relived gas goes back to the compress condenser cycle.

there is no such thing as free energy. Unless you can actually capture lightning there is no significant energy amount of energy in the atmosphere.

0:02 Combine concentrated solar and concentrated wind with a folding mirrored cone dish and a cylinder down the mddle lined with high temperature high efficiency solar cells. If you heat compressed air in the cylinder, you can drive a gas turbine with it. Some solar farms do that. They store the energy in a pile of gravel and recover the energy with a gas turbine to make electricity. This kind of system might generate six or eight times the elecyrical energy as the same area in regular solar panels for a small fraction the price. Some cars have a combination turbocharger, electric motor and generator to spin the turbocharger for faster power in between acceleration and conserve energy. It might be about the right size for a gas turbine to drive the dish energy system. 0:02

Just built a small air heater from 6 x 6ft evacuated tubes and some 1 inch stainless steel pipe and a 15w fan, heat output is pretty good. Well worth doing.

Just came across your video, and I agree 100%. I designed a burner to run in my converted wood stove, and I have been running it now for 6 years. It will heat my 800 square foot shop with no problem. If I crank up the oil dial, the stove can reach 1200 degrees fahrenheit if you turn the shop lights off, the stove is red, which means it's HOT! I have a good supply of used oil, which I filter. The bottom line is that it's cheap to run and gives off a lot of heat!😊

I have one suggestion, Can we use this rotar for tornado 🌪. It must rotate in reverse direction with multiple fan like branches of tree 🌳. It must work more on ground to destroy wind energy motion created by tornado 🌪. It's not difficult job to rotate fan in reverse direction of tornado. Wind energy of tornado will give energy to destroy tornado. Please think about it. Jay bharat.

I am really concerned about digital privacy though with Chinese cars or any high tech EV or ICE car. I would much rather prefer a very basic “dumb” EV with no self driving etc, rather than a “smart always connected” EV.

Hello - which of probably more than 100 available dehumidifiers is the most efficient? Is there a recommended model for high yields, longlasting and not to expensive? 50 Liters per day produced by 15KWh out of solar panels would be perfect for my finca in Spain. Might it be smarter to store most of the electricity and focus on nighttime water production?

Open an industry and put it into production..

SCREW EVs. Give me a BIG CUBIC INCH V8. 5-15 MPG 1000HP TWIN TURBOCHARGED . EV batteries explode and release all kinds of heavy metal into our water supply. N O T I T E R E S T E D😂😂😂😂😂😂

This is a fair comparison, will they be selling them in Europe soon? First goes to Norway for sure. Thank you 👍💪✌

Usually the production price is way higher for first EV cars of the brand

We need light cars, not anvils.

excellent idea

What makes those rotors rotate in the first place? Do they need external power from fossil fuels/battery to do this?

4:29 this problem was exactly what i was thinking ever since 2:26

Excellent. The more the merrier!

More or less conventional sails are coming back, too. Arianespace uses _Canopée,_ a ship with deployable aircraft wing like sails to transport its Ariane 6 rocket across Atlantic to their launch site in Kourou, French Guiana. The vessel is expected to save up to 60% of fuel in optimal conditions, or about 30% on average.

Surely any wind from the sides (not due to forward motion) will cause steering forces? Any variability in the wind will require constant rudder trimming (in addition to anything the ship would normally experience due to it's "sail area")

That’s pretty cool, why haven’t I heard more about these?

amazing rotors that saves fuel

Back to the feature place in an open paddock ,the most advance peace of engineering that technology ever produce in 2025 .

I don't satisfied with this video.. more details... please.👍

Is it possible to have an update for this video? More players have come on the market.

does the gasoline can use in motor engine such as motorcycle ? I saw some video from Indonesia and India that can use to run in Motorcycle, but did not mention whether need to refine or any substance to add into the gasoline

Graphene is a great metal. I have watched it's development. I'm glad to see you are making a presentation. I have a hearing problem and cannot understand the announcer.

At last Total is you cannot purchase and make it cheaply

What can you tell me about the best Polymere plant for plastic waste to fuel ?

Yay! A good wind turbine! Oh, 2 years ago! Wow... Their slow getting them going!

You didn't even touch on the fact that petroleum companies are pushing for H2 ICE vehicles because it is possible to make H2 from petroleum. This maintaining their profits. Any time you claim that something is becoming more popular merely because of their technology, you are basically lying.

Hydrogen energy yield is about 30%. So you need to consume 3kWh to get 1kWh worth energy hydrogen.

I m interested in your project and would like to have your contacts

I still think in the long run, once there is a better clean energy production, that H2 can become a reality. On the storage area there are so many new alternatives, bound to other chemicals that stabilizes the H molecule the H2 can be stored for ever, no worry about leaks etc. Thanks for bringing this one! 👍💪✌

Good information 💯😊

"still have a great car"? Damm thing is creating pollution.

Resurrect Stanley Meyer tech. Run on water.

Look at Michael Barnard and Michael Liebreich if you want solid info on H2. Liebreich came up with the very useful "hydrogen ladder" which shows where H2 has a role to play and where it clearly does not. Road transport is one where it does not, and logistics for transporting and storing H2 with its risks, cost, losses and the massively larger volume are some of the reasons.
