A earlier post states this generator will offload the grid by a terawatt / year, I am trying to do the math and have become confused. There are 8,760 hours in a year times 100 MW is 876,000 MWH. The other thing that might come into play is that if the sun does not shine 24 / 7, but instead produces useable heat more like 8 to 10 hours each day, we will give it 10 to make it easy, we get 3,650 hours times 100 MW becomes 365,000 MWH which is a third of a Tera-Watt-Hour if conditions are perfect. I might have missed that fuzzy math class the only day I skipped school. 8-) BTW Electricity Consumption Totaled Nearly 3,856 Billion Kilowatthours (kWh) in 2011, which is 3,856 Tera-Watt-Hours and this unit will contribute 0.000095% to the grid. If we build 1,000 of these we will have 1% of our needs at the fire sale price of only $1 trillion. I pray I am not picking at nits or have misplaced a decimal.
