But anybody who believes in a strictly Solar-Powered automobile is either a fool, or failed third grade math, or both.
That's not very fair or nice. Plus, you're wrong.
First of all, I believe that the proposed idea was not for a strictly solar powered vehicle but rather a battery-powered vehicle with solar for range extension and powering things like AC.
Secondly, quick google search showed some solar options that deliver much more power than you are saying. There are solar modules out there with efficiency around 25%, which means somewhere around 250W/m2. Multiply by 4m2 and 5 hours and that yields 5kWh for 5 hours in the sun. That's about 7x higher than your claim. Care to explain yourself? Are you manipulating numbers intentionally to make a point?
and god help you if there is ANY shadow, even a single 1cm wide line will drop charging rates DRAMATICALLY as any shadow causes massive loss to power for all the panels to one side of it even if they are in the sun.
ever hear of bypass diodes? With a properly engineered PV matrix this is not a big deal.
>Note: This has virtually no impact on the feasibility of actually doing said industrial work in space, given the added costs of getting materials *into* space.
Yep, that's the problem. Plus everything has to be hermetically sealed, radiation hard, protected from micro satellites, etc etc. Doing things on Earth is much easier and cheaper than doing things in space.
His ignorance of how solar works is pretty apparent from what he's saying. The flux of photons in space is about 1/3 more than than on earth (1366W/sq. meter in space vs 1000W/sq. meter on earth). Woopee. So you'd be willing to build factories and solar farms IN SPACE to get slightly more power? Nevermind that it will be thousands of times more expensive to put them in space; the radiation in space quickly renders all but the most expensive solar options non-functional in less than a year. This is a very stupid idea.
So... before graduation do the professors have a big get-together and look up all their students' myspace profiles? Was one of her teachers a stalker? What the hell was their motivation for looking up her myspace page in the first place?
Teacher in training Stacy Snyder was denied her education degree on the eve of graduation when Millersville University apparently found pictures on her MySpace page 'promoting underage drinking.' As a result, the 27-year-old mother of two had her teaching certificate withheld and was granted an English degree instead. There seems to be a couple missteps in their logic.
1. How does a picture of an adult drinking from a plastic cup while wearing a pirate costume constitute promoting underage drinking?
2. Giving her an English degree instead of a teaching certificate seems like a weird way to punish this offense.

So 5x more available power at 50000x the cost?
