Is this the microwave power from space idea again? /wcgw…
Might as well just start building the dyson sphere instead
This article feels like AI, generated from one sentence.
The solar panel is easy, it’s the cable run that’s a real bitch
Yeah, sending it wirelessly would have massive loss, probably around 90%+
It’s less about the loss and more about the space required for the receiver and the environmental hazard
That, and wiping off the caked dust.
LoL
That sounds like the least economical way possible to build out solar.
I think climate change mitigation can be the next scam after AI. Once AI bubble bursts they will start looking for new investments and I think climate change is ready to start generating profits. People are desperate enough to start investing money in things that will limit effect of climate change. Who will profit? Corporation that will work on those projects. Anything space related (solar panels in space, geoengineering) will require Space X/Blue Origin. Google, Microsoft and Amazon are already invested in nuclear fusion and modular reactors. Tesla is an energy provider. Any CO2 sequestration projects will require new startups, obviously backed by the same corporations. My guess is very soon we will see governments paying those companies to solve the problem they created. Even more money will be pumped to the 1%. It went form “climate change isn’t real”, to “climate change isn’t caused by humans”, to “it is caused by humans but nothing can be done about it”. Next step will be “we can fix it if you pay us”.
Pay to win is always the default in corporate world.
Countries will do everything except build nuclear power plants ig.
Don’t feed the troll
Renewables are going so hard, it’s not even a competition anymore
So could a fucking Dyson sphere. This article is PopMech-tier speculative trash. A flying car in every driveway, any day now since the 1960s…
solar panels on earth could reduce it 100%
This is an idea from the 1960s back when they thought solar panels would be like computer chips and remain super expensive in terms of area but become exponentially better at the amount of sunlight they could convert into electricity.
It makes absolutely zero sense to spend billions of dollars putting solar panels in space and beaming the power back to earth now that they are so cheap per unit area. The one thing you could argue a space based solar array could do would be to stretch out the day length so you need less storage, but that’s easier to accomplish using long electrical cables.
This energy would then be transmitted to one or more stations on Earth. It is then converted to electricity and delivered to the energy grid or batteries for storage.
How is the energy transmitted to Earth?
Yeah this article is severely lacking in any concrete details.
I’d also like to know how exactly it is that they plan to deploy massive arrays of solar panels to space. Most earth-based solar farms are huge and take up entire fields, some are a few kilometres across in size. That’s many orders of magnitude more massive than anything we’ve previously ever launched.
Plus whatever power transmission system they come up with would have to be powerful to be of any use but if it’s that powerful would present an active danger and would effectively constitute a space-based weapon system.
It’s a cool sci-fi idea but it is all pie in the sky.
Back of the napkin math:
Largest solar sail (much lighter than panels, but doesn’t produce electricity) 2000 sq meters
200w/sq meter
400kwp
Also iirc the space solar farms plans I’ve seen call for re radiating the energy back via microwaves to dedicated receiving towers on the ground
Yeah I’ve seen that. Microwave power beaming would work in theory it’s just electromagnetic radiation after all. But the vast majority of it is going to get absorbed by water molecules, because that’s what microwave radiation does, that’s why it cooks your food.
They’re probably going to bake a lot of seagulls as well.
All fun and games until a piece of space junk knocks into the satellite and you accidentally cut through the Dutch sea wall.
I think this was one of the possible disasters that could happen in Sim City 2000
Bzzzt
Or until sabotage happens, like with the baltic cables and pipes
NIMBYies in panic mode.
that’s some easier said than done statement there
Here’s the paper from NASA that this is based on.
