Apollo program materials spinoffs (gallium arsenide, GPS)

There's a lot of other things we need in this country that we could spend 400 billion dollars on, in my opinion, for a social good, than to send Elon Musk to Mars. I'm sure he's enjoying it and he could pay for it. I have my opinions about some of these things — I just gored an ox. They probably could defend themselves and talk about why it's useful. You can look back at putting a man on the moon — that brought us gallium arsenide, which is one of the great materials advances, I admit that, in LEDs and all those other things, GPS, and a lot of things come out of that. But you could also spend that money in other ways and develop sustainable, environmentally friendly technologies. Maybe we would have had solar power thirty years ago if we had invested some money in solar power thirty years ago. There are lots of choices and they're often made for political reasons.
