There are those who say tearing apart the world's lakes and oceans at their molecular level is a bad thing. Enviro-whiners mewl that Schund Electrolic Xerocells are only a stopgap measure, that by 14 August 23,146 AD mankind will again be searching for an energy source. Humbug! One need only burn the hydrogen to power refrigeration to balance Global Warming. The water returns without blemish to irrigate deserts. European bidets will be flushed with success. -- Uncle Al http://www.mazepath.com/uncleal/ (Toxic URL! Unsafe for children and most mammals) http://www.mazepath.com/uncleal/qz4.htm

Right, so all solar, tidal, wind energy can be turned into hydrogen from the local electricity generated via some electrolysis process or even better process, then transmitted from those areas into consumer areas with the Hydrogen Transmission Network. http://adda-enterprises.com/htnwebsite/home.htm I have got some very positive reactions to the idea, and things may start to happen!

What would it cost to rebuild the electricity grid or the network of pipes that carries water? Include the rights of way. None of that leaks hydrogen. idiot -- Uncle Al http://www.mazepath.com/uncleal/ (Toxic URL! Unsafe for children and most mammals) http://www.mazepath.com/uncleal/qz4.htm |
