By the way, those interested in independent power systems (solar,
hydro, etc, combined with batteries and inverters) really ought to
check out the catalogs and sourcebooks from alternative energy
companies such as Real Goods and Backwoods Solar.  Granted, you'll
have to tolerate a lot of environmentalist polemics, but they *do*
have useful, practical experience in engineering real, working systems.

Now if they could only get some of their other numbers right, like the
total amount of energy the sun radiates (Real Goods' figure is off by
1e9) and do a more balanced comparison between solar and fossil fuel
power that takes into account the energy required to produce solar
panels and the environmental costs of lead-acid batteries...
