Picture this: sunlight harvested 400 km above Earth, turned into invisible microwaves, and beamed straight down to run a coffee maker in your kitchen.
That's not sci-fi.
That's Japan's plan for 2026.
Meet OHISAMA — Japanese for 'the sun.'
A government-backed satellite, roughly the size of a washing machine, about to attempt something no country has proven at real scale before.
The satellite weighs just 180kg.
It'll unfold a 2 square metre solar panel in low Earth orbit.
Power output? About 1 kilowatt — barely enough for a coffee maker.
But that's not the point.
The point is proving the beam actually works.
Here's the wild part.
The satellite will be moving at 17,000 mph.
Yet it must keep that beam locked on target with an error margin under 0.001 degrees.
One tiny wobble, and the whole beam misses Japan entirely.
Japan imports over 90% of its energy.
No sun at night. Clouds block solar farms. Land is scarce.
Space doesn't have any of those problems — sunlight up there is nearly 24/7.
So this isn't a moonshot experiment for fun.
It's a slow-motion answer to an energy vulnerability Japan has lived with for decades.
Efficiency right now? Just 10-15%.
But the roadmap is aggressive:
That final version could even power lunar bases in the Moon's darkest craters.
A coffee maker today.
A power grid — and maybe the Moon — tomorrow.
That's the actual bet Japan is making.
That's all for now!
