The Dawn of an Age of Solar Flight?

From the 1950s to the 1990s, engineers explored the limits of what was possible in aviation.

In so doing, however, they hit inevitable barriers of cost effectiveness.

We’d made our point with elaborate manned space missions but had no financial incentives to keep blowing fortunes on them.

The concorde, a supersonic jet liner made by the Europeans proved so expensive that not even rich people could keep it commercially afloat.

Super expensive space shuttles with nearly 1/60 odds of blowing up on take off haven’t proved worth replacing.

The age of exorbitant spending just to prove a point is over.

First, new technologies and engineering projects must be cost effective.

And this brings up an obvious frontier in flight if we want to be as energy effective as possible.

Solar aircraft.

It would seem we’re approaching a point where batteries can store enough solar power to get through the night or in bad weather.

Just imagine the larger implications of this…

How long until people actually start living in the air to get away from the power of governments and rent seekers?

Dyson Sphere

Dyson sphere is a hypothetical megastructure originally described by Freeman Dyson. Such a “sphere” would be a system of orbiting solar power satellites meant to completely encompass a star and capture most or all of its energy output. Dyson speculated that such structures would be the logical consequence of the long-term survival and escalating energy needs of a technological civilization, and proposed that searching for evidence of the existence of such structures might lead to the detection of advanced intelligent extraterrestrial life.

Since then, other variant designs involving building an artificial structure or series of structures to encompass a star have been proposed in exploratory engineering or described in science fiction under the name “Dyson sphere”. These later proposals have not been limited to solar-power stations. Many involve habitation or industrial elements. Most fictional depictions describe a solid shell of matter enclosing a star, which is considered the least plausible variant of the idea (see below). Link
