http://www.physorg.com/news125842769.htmlSachs and his colleagues have started a company called 1366 Technologies. With the help of a recent $12.4 million grant, the team is building a pilot-scale manufacturing plant to fabricate their first batch of solar cells. The cells currently have an efficiency of 19.5%, and cost about $1.65 per watt. That´s a 27% improvement in efficiency over similar commercial solar cells of today, which have about 15% efficiency and cost about $2.10 per watt. Take a look at prices: http://www.ecobusinesslinks.com/solar_panels.htm Above 3 dollars per watt. That last time I calculated I used 6 dollars per watt (installed by home owner). It was profitable then when adding in rebates from the tax collection fund. There is a point at which the failure to invest in power will be relatively too costly. See this? It is on the way. As the price on 'collective' power continues to increase and as the cost on power-independence continues to lower there will be a point at which the only one's remaining on the dole will be those who can afford that hihger cost while everyone is free of it.

 Hydrogen battery? http://www.millenniumcell.com/fw/main/home-177.html EATONTOWN, N.J.--(BUSINESS WIRE)--March 11, 2008--Millennium Cell Inc. (NASDAQ: MCEL), a leading developer of hydrogen battery technology, today confirmed that its Hydrogen on Demand(R) technology provided the energy storage for a record-breaking nine hour flight of AeroVironment's (NASDAQ:AVAV - News) PUMA. The PUMA, a small unmanned air vehicle (UAV) was powered by Protonex Technology Corporation's (LSE http://www.treehugger.com/files/2005/08/hydrogen_batter.php We've hinted at the idea of the hydrogen battery in earlier stories. Progress Energy has collaborated with the State of Florida to get a complete hydrogen battery system functioning as part of a public education program. It includes a solar panel, a hydrogen electrolyzer by Hydrogenic's / Stewart Energy subsidiary, hydrogen storage capablity, and a fuel cell, pictured here next to the wildlife pavilion at Homosassa Springs Wildlife State Park. The Progress Energy web site linked here mentions a forthcoming streaming video of operating performance metrics. But don't wait. We recommend you take the time to view the technology overview video already there. Nice Progress!  http://www.hydrogenics.com/our.technology.hydrogen.generation.asp While there are many cases where it does not make sense to use the available electricity to make hydrogen in order to make more electricity, there are many instances where it does make sense. It boils down to more of an economic argument than a scientific argument that requires some understanding of off-peak power availabilities as well as how to optimize renewable energy sources such as wind and solar power. Today, wind and solar power are stationary intermittent energy sources, limited by the hours in which they can actually generate power that has to be used ‘there and then’, or be lost. Hydrogen by electrolysis becomes a ‘dispatchable’ energy option that allows later use of power that has been previously harnessed by the wind or the sun.

The Chart is poor. Solar Panels are now affordable as a means of reducing the cost of electricity. That means that a person can invest in solar panels and reduce their monthly electric bill. That means that the whole concept of discrediting electric cars based upon the high environmental costs of electricity is ludicrous. If you have an electric car and you have one because you want to reduce monetary costs (avoid the high price of gas) then you can reduce the high price of electricity with an investment in Solar Panels. AND Solar Panels are becoming cheaper and Solar Panels are producing more current. The affordability of Solar Panels (as a means of reducing the cost of consuming electricity) is getting better (more power for less cost). If the idea behind a change from petroleum powered transportation to electric powered transportation includes an environmental concern (added to the monetary concern) the idea is to stop burning gasoline and stop producing carbon dioxide and if that additional concern (the environmental concern) applies to the automobile it (the environmental concern) can apply to the Solar Panels. There you have, now, two concerns. 1. Monetary (you spend less money on electricity and less money on gasoline) 2. Environmental (you produce less pollution with the car and you produce less pollution as you make your own electricity out of sun-light). There is a third concern that may be even more important the first two concerns. You become independent. You are POWER-INDEPENDENT. If the flow of collective gasoline stops – you keep going. If the flow of collective electricity stops – you keep producing electricity. That is called a win/win situation. More benefit Less cost
