What if we could engineer a gigantic megastructure

capable of harvesting every bit of the Sun's energy?

In 1960, astrophysicist Freeman Dyson theorized another civilization

that found a way to meet their ever-increasing energy and space demands.

This hypothetical advanced civilization built a hollow sphere around their own sun,

and provided themselves with an incredible amount of energy

How would we go about building this space-level structure?

Theoretically, if we built a Dyson sphere,

we'd have access to a colossal 400 septillion watts of solar energy.

That's a trillion times more power than our entire civilization consumes today.

The problem is, no known material is strong enough

And even if we created one in very large quantities,

a tiny gravitational pull towards the Sun would make our solid sphere uninhabitable.

Not to mention that it would be totally unstable.

Every meteor strike would push a part of the sphere toward the star.

But all these issues can be solved with a simple adjustment.

Instead of building a solid Dyson sphere,

A myriad of solar collectors with their individual orbits around the Sun.

One that's able to provide the energy needed for this construction project.

It would become our space mine for the iron and oxygen we'd need.

From those elements, we'd make highly reflective solar collectors.

The giant mirrors would reflect light into a small solar power plant.

From there, it would beam the energy to where we need it.

before we moved on to Venus, Mars and the outer planets.

Even nearby asteroids would be decimated.

However, even just deconstructing Mercury

would supply us with enough energy to power up our supercomputers,

large rotating space colonies in the habitable zone of our Solar System.

Maybe, if we were lucky, we'd find other, more efficient sources of energy
