How has the thread swung way off topic? The topic is putting solar on the i, and at least up to the mention of ICE's, it has stayed on topic. I probably hi-jacked the thread, but it's still on topic. The 35.5 meter trailer is how much solar power is required to run the i on the highway without running the battery down, sort of like a hybrid's 'charge-sustaining' mode. This would be great to drive across a state, but would be way overkill for anything under 200 miles.
I posted my situation because it fit the scenario for putting solar on an i. I will be changing work locations soon because we were contracted to installed a distributed antenna system, and are almost done. My plan for a car is a solar car (designed around the solar array). It would have a 1,000 watt solar array, enough battery capacity to travel a real 150 miles, plus whatever solar kicks into the system. It would also weigh less than 2,000 lbs, and only have three wheels. I've gotten to the point where the design plan is 99% complete. http://home.earthlink.net/~timster/id11.html
Since I'm on the topic, if an outlet would be available for me to use (level 1 or 2), would it still make little sense to drive an i and not buy a Volt or something?
