Would a Dyson sphere be possible?

Feasibility. Although such megastructures are theoretically possible, building a stable Dyson sphere system is currently far beyond humanity’s engineering capacity. The number of craft required to obtain, transmit, and maintain a complete Dyson sphere exceeds present-day industrial capabilities.

What could we do with the energy from a Dyson sphere?

Harnessing even a tiny fraction of the sun’s energy using the Dyson sphere would give us the energy for projects such as terraforming planets, forming space colonies, or building other megastructures such a stellar engine to move our star, and thus the solar system, through the galaxy.

How efficient would a Dyson sphere be?

A Dyson sphere is a futuristic concept, so we can assume humanity already has solar cells with the maximum theoretical efficiency = 86.8\%. (100\% is impossible because of thermodynamics laws). The sun gives off 3.85 x 10^26 watts (385 trillion terawatts), so we would likely be able to harness 334.18 trillion TW.

Would a Dyson sphere melt?

But after absorbing and exploiting the solar energy, the structure would eventually have to reradiate the energy or else it would build up, causing the sphere to eventually melt, according to Dyson.

How long would it take to make a Dyson sphere?

The rule of thumb for big projects is to base it on the doubling time. So if it takes 1 year to double the set of machines/collectors, and you start with 1 square meter’s worth, you would reach the scale of a 1.0 AU Dyson sphere in about 79 years that way.

Is Halo based on Ringworld?

Bungie themselves have commented on the similarity of the game and Niven’s novels, and have since the original game was first announced. It’s worth noting that though Halo takes place on a ring-shaped artificial world, the story, characters and world bear no relation whatsoever to Niven’s excellent Ringworld novels.
