Money isn't actually something that has value in and of itself, it is an abstraction for something that has value. The actual value is on the work it represents and the value add that work creates. If money just sits there doing nothing and not producing more work, it is not a benefit to the system.

Capital is good when it is invested into more production. In the past, that was primary accomplished by the bank investing your savings or the stock market doing the same into companies expanding their production.

Much of the problem with modern capital is that instead of investing into more production, it is focusing on non-productive or anti-productive strategies - downsizing (anti-productive), stock buybacks (increases stock price but no investment into real wealth production), bubble speculation (gambling).

Sending them to space is totally not a viable means to compensate for population growth on Earth. The cost for each person is so astronomically high we couldn't afford to send more than a handful of people. The way to get population under control on any planet is to get people to have less kids.

And for the same reason, the only viable way to grow a population on a colony past a bare minimum is to get them to have more kids.

You're unlikely to approach 50% efficiency in converting water to hydrogen onboard a car which is done by USING ELECTRICITY. Which would then have to pass through your 50% (real world) efficient fuel cell to turn back into electricity to drive the electric motors that fuel cells drive.

Battery recharge efficiencies are near 90%. Even in a fuel cell car it would be stupid not to use them to store regenerate breaking power.
