the hydrogen 7 was covered by bimmer mag a few months. i think it is pretty impressive, but i am hesitant to give up my gasoline powered ICE just yet.

an engineer said that they can make much more powerful and efficient hydrogen engines compared to regular gasoline ones, but they could not in the hydrogen 7 because it required the ability to use both regular gas and hydrogen. apparently, an all hydrogen engine would be sick.

Yeah, they released/leaked that about a year ago.

Reportedly, there will be 50 made. Around 20 or so are being sold in the states. And I think they all went to LA or California. Also, all 50 have already been bought.

I'm all for solar/hydrogen fuel. It is a great combination. I think it is only a matter of time, especially if things continue to brew in the middle east.

hydrogen is the worng way
the process of making hydrogen requires almost almost as much or even more engery than what is wasted by the combustion of gasoline. The Tesla Roadster is the right way...

BTW; they've been working on the Hydrogen 7 for I think about 15 years now and still haven't managed to make it ready for market

Hydrogen is the wrong way and batteries are the right way?

Do you realize the output (in BTU's) hydrogen fuel has compared to a lithium ion battery? Granted, hydrogen has a long, long way to come in terms of refining it more effectively, but batteries (a technology that has been around since Edison) are no where near as effective as people think. Both technologies have a long way to go to be any bit marketable to the general public, but to count one out because it hasn't come very far in a short amount of time is kind of silly.

BTW, Telsa Roadster is $93000. Would/can you buy one?

Hydrogen solar = renewable : Oil = nonrenewable.

If water is used for the soure of hydrogen, then the biproduct is steam. Must better than exhaust in my opinion!

Fossil fuels (coal) are used currently in electrolysis process generally used to generate hydrogen from water on a large scale. As mentioned before, this process is very inefficient. This is similar to the arguement that ethanol will solve all our problems via corn. It would be great if it were as simple as that, but until refining processes and technology catch up, implementation of such processes are generally counter-productive

That is why I said solar/hydrogen by splitting the water molecules. What I like about the hydrogen developments is that it represents a shift in thinking amongst people in the industry, to some degree. It is a step in the right direction, I think.
