Uhh there are tons of companies making these now. You can literally drop one of these in the middle of nowhere running off solar, pulling hydrogen from the atmosphere.
Because solar is free?
Guys, we can stop trying to solve climate change, we already have free energy!
Are...you suggesting solar isn't free energy?
Solar costs whatever it costs to buy, install and maintain a solar PV farm, which is not nothing.
If you're going to build a solar PV farm, you're obviously going to want to sell the power you generate in whatever way is most profitable.
At the moment, it's still magnitudes more profitable to sell solar back to the grid than it is to feed it into an inefficient hydrolysis plant, create a load of hydrogen and oxygen, and then move it by leaky tanker somewhere to sell it.
These are designed to be setup and turned into fueling stations, not creating the hydrogen and shipping it elsewhere. You still need substations near superchargers, which requires a lot of power lines to be run. In the middle of nowhere they're pointless to build.
Jesus, of course it's not free. Solar panels are not free, the land you put ten on is not free, construction is not free and the infrastructure needed to supply energy during the nigh (storage or another source of energy) is not free. How is this not obvious?
Lol yes because a super charge station is free...and so is the land and the wires and the sub station to get it out in the middle of nowhere... totally more economical to put in a fucking substation for superchargers in the middle of nowhere than to use solar hydrogen lol
WTF are you talking about? So solar if free because 'solar hydrogen'? You're not making any sense.
Solar energy is free, I'm not the one that's made a claim that it's not. I'm also not the one that has zero understanding on how superchargers work...all of you keep thinking they can just dump one in the middle of rural America and it'll just magically work. You don't seem to understand the huge amount of power draw these things have.
You don't seem to understand that the only thing solar energy does for free is to heat the ground which is kind of useless for moving cars,
Yes because using solar to generate hydrogen.... totally just heats the ground.
Yes, because the hydrogen just appears there. No machinery needed. It just forms pushes cars. For free. Amazing!
Yeah cause that's what I've been saying.... totally way to completely be ignorant.
Yep, that's what you've been saying. Solar generates hydrogen for free. Just like that. You just park you car in the sun and it moves. Unlike a supercharger which has to be build hydrogen is just there. No buildings needed. Exactly what you said. Word for word.
Lol the ignorance from you lot is hilarious.
Except it's you that keeps writing stupid shit like "solar is free".
Because solar is free, just like wind is free....you all keep equating that because it requires infrastructure that it's not free...this is the dumbest shit ever, it's fucking obvious that it's not free in that sense...
Yeah, coal is also free. I just lays there in the ground. It doesn't cost any money to make it. Obviously you need infrastructure to mine it and burn it but other than that it's free. Right?
Yes because I forgot how when you build a coal mine it just comes out of the ground without any work at all, and you don't need to ship it anywhere, and we can just put it in the middle of our homes and it produces energy. It's like warcraft mining.
Yes, I'm happy you're starting to understand. It's the same as with solar. It just shines on cars and they drive. You don't need to build anything like panels or hydrogen storage or pipes to move it. It's simply free energy. Like coal.
Lol
