Suncatcher doesnt need any water so its ideally suited to desert conditions. If this new plant starts delivering electric power cheaply this summer then it will be very significant as it can be scaled up rapidly. Electric car batteries can store immense amounts of power. Cars consume five times as much energy as is generated in USA power stations , so wind can displace a lot of fossil fuels by recharging car batteries when the wind is blowing.

Around the edges, but most of the area would be shaded. > Suncatcher doesnt need any water so its ideally suited to Grass needs water, lots of water. Cows need water. > desert conditions.

Maybe, but the transmission lines needed to transport the power to somewhere where it would be of use can't. > Electric car batteries can store immense amounts of power. Yeah, compared to a flashlight battery, but not anything real. > Cars consume five times as much energy as is generated in USA power Since cars don't run on electricity, this irrelvant even if correct. > stations , so wind can displace a lot of fossil fuels by recharging > car batteries when the wind is blowing. Babbling nonsense; you were talking about solar power and now you're babbling about blowing wind. You are still an idiot. -- Jim Pennino Remove .spam.sux to reply.
From: habshi on 31 Jan 2010 07:39 Wonder if eliminating the tracking system and just having a parabolic dish which always focus sunrays coming from any direction to a point would make the whole thing a lot cheaper? One B and B which offers free car recharging. http://www.mercurynews.com/business/ci_14248792

Sure it would, but since that is impossible for a passive reflector, the bottom line is no. You are still an idiot. -- Jim Pennino Remove .spam.sux to reply.

BBC today showed a great method of cooling . Water is sprinkled over charcoal in permieter wall a few inches thick. The sun evaporates this water and carries heat away . Temp falls from 30 to 18C ie comfortable. So maybe during the summer we can clad a building with a charcoal coating and let water sprinle on it . http://www.bbc.co.uk/programmes/b00nmt73 |
