It takes more energy to produce the generator components than it can produce in its lifetime. Such wasteful uses of scarce resources is generally considered inefficient and politically incorrect. More ecological would be a solar powered vulcanizer. Something like a Fresnel lens plus mounting stand could be used to concentrate sunlight on the patch area sufficient to melt the sulfur. When not vulcanizing patches, it could be used for cooking. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

That does sound nice and ecological, provided the Fresnel lens is made of something carbon neutral. Best would be to hand carve it out of naturally occurring quartz. Another choice would be to gather and recycle broken glass bits from the roadway. This has the advantage of reducing the need for the lens in the first place. But hmm, that might lead to a marketing problem... It's beginning to look like properly patching a bike tire is one of the world's most complex problems! - Frank Krygowski |
