Quite counterintuitive.

Re: nuclear fuel - you just need to get that spent nuclear fuel off the Earth (i.e. shoot it at 11 km/s) because you do not care how long it will take to crash into the sun and you can use solar energy to slow it down gradually.
That is if you really want to get rid of something that might be an important resource down the road, in a very expensive way.

I thought the context of the title meant "hard" as in "a solid, unyeilding surface", rather than "difficult". Was expecting something a bit more interesting, although this was still... enlightening.

The bass in the background is extremely annoying. Cut the volume by 75%, or remove it altogether, and this video would be much better.
