We’ve recently figured out beaming power to another location. We might be able to start a Dyson swarm, which is just a collection of solar panel satellites that beam their energy back to earth.

I’d like to also see the start of space resource extraction/refinement. The more of that Dyson swarm we can build without having to lift it off earth, the better.

A massive high speed railway network across North America, coast to coast. Russia did it, China did it, most of Europe did it. Canada and the USA have no excuse.

Property acquisition costs and legal fees are immensely more expensive in the US. Have to obtain those thousands of miles of land for rail development from somebody.

There are ways. Maybe bring our number of aircraft carriers down to only 3x the rest of the world combined instead of 5x, just as an example.

Just want a space elevator, surely we can’t be that far

We can’t make long enough pieces of anything strong enough to handle that level of strain.

Universal healthcare, public transit, communism. Or at lease food for everyone, housing for everyone and communication for everyone.

Economic communism won’t be achievable until we fully automate the economy and institute some kind of technocracy or lottery style political system.

A truly “stateless” society is a joke, but separating the economy from the state is only possible if we are all out of jobs.

Nuclear bomb fueled rockets to space. Look up project Orion.

You didn’t ask if it was bad, you asked if it was practical.

Depends on which side of the exhaust you are on.
