It's not the power out there. It's the transport that is, well, tricky. You basically have two options:
- low orbit for the energy station. This means you r station zooms by at mach 25. Aiming your death ray/energy beam is a little tricky then.
- geostationary orbit. Your energy station is an absurd 36000 km away. Good luck focussing and aiming then.
Oh, wait, there's also the fact that nobody has ever, ever transmitted reasonable amount (like, within 10 orders of magnitude of this endeavour) of power to a receiver.
I am sure it is also a real piece of cake to boost that 1 million tons of equipment into orbit needed for the job. Especially when the US does not have a normal space-faring capability anymore.
No, just opportunities. No mad dreams at all. Where can I invest? Surely this is not a scam??
