But a economical Hydrogen Fuel cell could be used in many applications besides transportation. And it is not a dream, they have already done most of the work.

Recently, Toyota announced production of the Mirai hydrogen fuel cell car to be sold in California. But what is a hydrogen fuel cell? Without going into all the DETAILS, the basic idea is that you can get an electrical current when you combine hydrogen with oxygen (you also get water).

But is it really effective? Don't you lose energy by cracking hydrogen and then turning it back into water? Well, the details matter.

If you need a reliable battery with a large fuel supply, hydrogen fuel cells are a good choice. For EXAMPLE – in space, hydrogen fuel cells are a perfect choice. If everyone on Earth used the fuel cell, we would have a problem making enough hydrogen (and storing it).

Please read the article to understand why Toyota might do it, despite the CRITICS view that it is a silly futile waste of time.
Hint: Look for the phrase 'nuclear fusion.'Thanks for the interesting read. I thought the author was getting side tracked until it all came together in the end.. Quote from: DaveLembke on March 08, 2015, 01:25:51 PM
