Housing for everyone and in a way that mega-cities are walkable
If its a mega city how can it be walkable? I wouldnt want to walk an hour to get to my job that would have been a 15 minute walk. Or am i misunderstanding what you mean by walkable?
Walkable doesn’t necessarily mean the entire city is within walking distance just that where you live doesn’t require you to have a vehicle and you can walk to everything you need. Being able to walk to work and the grocery store and to any entertainment is so nice.
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.
Canada’s excuse is “we’re roughly as big as the US but have a way smaller population and GDP. I really don’t think it’d be financially justifiable for them to build a rail equivalent to the trans-Canadian highway. It’d be a non-starter in a political sense.
The US, on the other hand… yeah. We genuinely have no excuse.
A majority of Canada’s population lives in a straight line from Toronto to Québec, but they can’t even manage that.
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.
Housing for everyone, food for everyone, clean energy (nuclear power, though we would do well to advance the tech a little is immanently practical).
Those are all easy mode stuff that would dramatically improve the world for a lot of people, but we could do more.
Hard mode: Orbital rings.
We would have to develop some tech, but not nearly as much as you might think.
Don’t even need nuclear, renewable energy at its current pace will get us to 100% renewable by 2050, which is about as far away as any nuclear plants you started constructing today for way, way less money and zero waste storage issues.
There’s basically no point building any other kind of energy at this stage. Giant, expensive power plants that require huge amounts of expensive fuel and large expensive workforces simply can’t compete with panels pumped out by factories you can install anywhere that generate free energy for decades with little to no maintenance.
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.
uhh
Nuclear bomb fueled rockets to space. Look up project Orion.
isn’t that bad?
Depends on which side of the exhaust you are on.
You didn’t ask if it was bad, you asked if it was practical.
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.
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.
Not yet!
