If they already purchase even though there is a risk of being imprisoned, then they will still attempt to purchase if they punishment is less severe.

Perhaps you are right, spacebro. Let there be a peace between us.

>1965: An astronaut in space holds a conversation with an aquanaut underwater, marking another milestone in human communication.

>Astronaut Gordon Cooper, orbiting the Earth with Pete Conrad in Gemini 5, hooked up by radiotelephone with an old pal, astronaut-turned-aquanaut Scott Carpenter, who was living and working 205 feet beneath the surface of the Pacific Ocean near La Jolla, California, aboard Sealab II.

A similar call occurred a few years ago between the Aquarius and the ISS, and Scott Carpenter was able to recreate his historic call in the 90s from the Jules Undersea Lodge to the crew of the space shuttle. Someday, people will make calls from subsea colonies to colonies on Mars without any conception of the history involved or the significance of the act.

And space justice too. In these hard times, space colonization needs just as much promotion as sea colonization.

Seabro/Spacebro solidarity!

>>the idea is currently shelved deemed to be too risky and too complex.

To get the obvious commonalities out of the way; The life support systems for every space mission since the first were derived from technologies originally used to breathe underwater. The same materials, hull designs, etc. were used for thermal insulation and pressure resistance (but from within). The CO2 scrubber is another submarine innovation that made extended stays in space possible, and the joint designs used on old atmospheric rigid-shelled diving suits have been applied to more flexible, durable space suits. :3

To mine resources offworld, you must first escape Earth's gravity well. The cost of doing this currently means that even if the moon was covered with gold bricks waist deep, we could not bring them back and make a profit.

To mine the sea, you need only succumb to Earth's gravity well. It takes very little energy to get there. These minerals are right on our doorstep in rich, pure surface deposits and in nodules embedded in easily excavated manganese crusts around hydrothermal vents. These vents are incidentally also of great scientific interest, providing a dual rationale for stationing habitats there.

Space is undoubtedly our future. But the sea is also our future, and closer at hand. Mastering the resources of the ocean and the technology necessary to get those resources will allow us to provide for the material and energy needs of a growing population while simultaneously preparing us to use similar technology to live self sufficiently on other worlds.
