Dear Mr. Julian Cox:
I do not disagree with the comparisons you have made between solar cells and fuel cells.
"1.EV only transport system. Renewable energy hits break even per mile vs Natural Gas electricity generation at 3.30/1.25 = 264% of the cost of natural gas. For example if natural gas costs $5 per 293 KWh (true on average) Solar can compete in terms of cost per mile at $13.20 per 293KWh or 4.50 US Cents / KWh. . . ." Julian Cox
There are better sources of data to draw from, though. For example, the City of Palm Springs ran extensive real on the ground tests with real functioning buses and real solar arrays, for years, and they were happy to share that data with me. My comparisons between solar cells and fuel cells were based upon that data and from other similar sources. The results I obtained are somewhat different than yours but, not so different to be of any real interest.
In addition to comparing solar cells with fuel cells, I am in the process of compared solar cells with permanent magnet generators, in theory. See, Charles Flynn's US Patent #6246561, June 12, 2001. To date, there are no real world applications of permanent magnet generators to draw data from; outside of top secret sources, that is. This secrecy makes the comparison that much more difficult to complete.
Nevertheless, I believe that people of similar interests to yours would benefit by such a comparison. When I have completed my comparison between solar cells and permanent magnet generators, I will forward it to whomever wishes to see it.
Conceptually, there is little doubt that a robust, resilient national power grid is a vital public interest to all persons and businesses. Perhaps then we should start to treat it as such and make it a truly public resource managed in the public interest?
Completely separate out the business of generating electricity (multiple players, regulated market) and delivering electricity (publicly owned, managed, and paid for). If I have a solar array that produces more electricity than I use I should be able to market the surplus while paying to maintain the grid. It's in my interest that my community has excellent public schools and roads, even if I use none (the schools) or a very small fraction (the roads). The electrical grid is no different.
