Currently we get it from fossil fuels, which is running out, heavily pollutes, and destroys the natural ecosystem. Nuclear was discovered, but it’s super complicated to handle and radioactive. Renewables are hit and miss, and must require a massive energy storage system in battery or water storage potential energy. Solar doesn’t always shine. Wind doesn’t always blow.
But in space, energy is infinite. For as far as we can see.
The problem is getting up there, and bringing it back down to earth.
But, what if we can harness it? In the form of solar collectors, and beam it back down to earth as microwaves or lasers. We can have vast fields of microwave collectors that can convert this energy back into electricity. Or laser receptors that can convert the laser back into electricity. No more pollution. No more environmental degradation. What you get is pure, clean, energy. All year round, day or night, rain or snow.
The challenges are great. The impossibilities are high. But the consequences of not achieving this is far worse.
