It is a good premise. I hope the model works. This is a great (looking) idea for places like cities where space is so limited but there is so much rooftop for solar collection. I am a big fan of wind power but it is situational since we are looking at the south shore of lake superior and a $5000 windmill and $1000 of batteries will run your home pretty much in perpetuity. Winds are constant due to the heat-sink effect of the lake.
Can't listen to the video now (sleeping 3 yr old beind me ) couldn't find it anywhere in type but maybe I'm just missing it. It says there are no reps near me when I put in my zip but is shows sites all over the map in Oklahoma. Maybe I'll just send them a note.
I heard that though goverment made windmills are really expensive and big, one for your house does not need to be very big or expensive and you get a lot of electricity out of it . If everyone with a back yard had one that would be a lot of electricity. A real help to global warming. rose
