I drove an electric car for seven years because of its advanced technology, not because I have any concerns about energy resources. I have none at all. And when environmentalists say that global warming is dangerous, unprecedented and that we'll have a tipping point for atmospheric carbon dioxide, it's just nonsense.

Space travel is the only technology that is more dangerous and more expensive now than it was in its first year. Fifty years after Yuri Gagarin, the space shuttle ended up being more dangerous and more expensive to fly than those first throwaway rockets, even though large portions of it were reusable. It's absurd.

The Russians did much bigger space launch vehicles for launching satellites and for getting men in orbit. They did that much sooner than America because America was very good at something else.

NASA is doing nothing but development. They're not doing research in manned spaceflight at all and I see no reason for them to do that because we already know that it will work and we already know exactly how it will work.

America was good enough to make a small compact lighter weight nuclear weapon. The Russians still had these big clunky heavy ones, so they had to build the big boosters in the arm's war, so now all of the sudden Russia could take off the shelf and put into orbit much heavier things than we could, so that's why they had the original leadership.

NASA's myriad failures are in many ways the natural consequence of a catastrophic combination of bureaucracy, monopoly, and a calcifying aversion to the kind of risk necessary for innovation.
