Lots of progress in the cold fusion (aka Low Energy Nuclear Reactions) field. What was once fantasy is now scientific fact. I hope you guys are paying attention.

Think about cosmic background radiation. All of that kinetic energy zipping back and forth everywhere. What if some of the Sun's energy is dependent on cosmic radiation? and some of that energy is distributed among nearby planets(Birkeland currents)? Notice how our solar system isn't really isolated from the rest of the Universe? Now apply that same logical reasoning to a smaller scale, the (sub)atomic scale.

In 1989 cold fusion was discovered by two electrochemists, Martin Fleischmann and Stanley Pons. Since then, there has been lots of progress. The videos are important because it details a major milestone toward understanding cold fusion along with newly discovered hazards. Watch and you'll never see arc welding the same ever again.

Mr. Fusion in the trunk of your car powering an electric motor. No more battery bank. No need for a multi-billion dollar mega-project that goes nowhere.

Or Mr Fusion powering an HHO fuel cell to supply hydrogen gas to the internal combustion engine. Just add water.

Every house becomes an independent power plant on the grid.

so it will never happen then. or do you think big money is just going to sit back and let themselves be rendered irrelevant. that the us will allow oil - that backs the useless dollar through the military industrial complex - be rendered irrelevant. do you really think TPTB will allow any shit nation or company free energy, any household getting free from the system and completely overturn the power hierarchy???

give me a break. first dudes who discovered cold fusion did a remarkable job of proving it was real but nothing at all happened. now theres some new waves and then nothing will happen again.

Under that logic, this is not a solar powered cart. Its a normal electric cart with solar panel.

That’s 10 HP on the motor, not the panels. It’s got batteries in it. I’m guessing they are assuming 8-10 hours worth of sun will get you 30 miles of charge per day. You’re right, it’s an electric cart with a solar charger strapped to the roof not a true solar vehicle.

Holy shit! An EV that isn't an expensive luxury car piece of shit with hundreds of pounds of batteries that relies on energy from coal power plants to run. You can't have that or else people would actually be able to afford and buy it and greenhouse gas emissions would be reduced.

In all seriousness, it blows my fucking mind that companies are prioritizing the production of electric cars that almost nobody can afford that use a shit ton of power and batteries compared to the Bako Sunny which relies on solar energy and is nice and small so it isn't incredibly wasteful to produce and use. And it looks cute to boot. A vehicle like the Sunny would definitely end up becoming my first EV purchase and I'm sure for many others too.
