Re: No, electric cars (still) aren't crashing the grid. (Long distance DC lines) ...
Spend just 7 Billion or about what we spend for coffee and we couild send
solar power westward to serve the 2 hour Duck's back peak demand on every
solar day from California to Maine. THen extend it another 1200 miles from
a floating off shore solararray in the pacific and capture the last two
hours of sun over the pacific to feed the sunset hours in California and
Sounds crazy today... but entirely possible. Bob
