Appreciate you for sharing. I am going to revisit this blog. I am a room decorator for five years. My home decorating tip of the week is: Do not overclutter a room. Walking area is key.

Both types of cathode are now in existance. The two gases can be stored indefinitely and re-combined in a fuel cell. The byproduct is water, which can be recycled in a closed-loop system. This is a major breakthrough in storing solar-derived energy that solves major storage problems and provides on-demand generation of electricity at any time.

If we could make the plants cheaply enough and it were possible to have them small enough to be useful, there is promise here. Cost, efficiency and size are real problems. Then, the fuel must be transported. LOX and liquid hydrogen cost a lot to compress, cool, liguify and transport. The tanks are heavy and the residence time in the transport tanks is limited. And then there is the safety aspect, especially in passenger vehicles. Time and economics will tell. If this technology can make it WITH NO TAXPAYER MONEY being wasted, I am all for it.

Excellent. It's right around the corner. Big proponent of fuel cells. I don't understand why more money isn't put into the developement of fuel cells. So much money has been invested into bio fuels and it seems antiquated. Fuel cells make so much sense for so many reasons. I’m very excited from reading this article. Excellent.

I am a supply business owner living & working out of Taiwan & China, and would be very interested to speak with Professor Gray about ways we can cooperate in order to bring down the costs of this new technology, to make it accessible to many more people around the world!! I believe such project will be a great challenge for a worthy cause, one that we all can do something to alleviate! I am still a small business, but have great Team & good connections in Taiwan & in China. Would be willing to help Professor Gray in his cause, even if there is no room to participate for some profit! Thank you!
