Comment Should have been Ascension Island (Score 2) 151

While I was VP for Public Affairs at E'Prime Aerospace, we evaluated various sites for establishing a space port to launch our MX-derived rockets. It turned out that the presence of a military air strip at Ascension Island allowed a military jet transport large enough to deliver entire launch vehicles. Of course, the MX system was solid fueled so we didn't have to transport cryogenics long distances, but it would be feasible to set up a LOX facility on the island. There is a particular coastal cliff that is ideal for a launch pad.

Look up Carbocrete's properties. While its true it does require some sand, in addition to the CaCO3 and carbon fiber, it requires much less sand than ordinary concrete and no rocks. Moreover, sand is ubiquitous on the ocean floor. A refinement of the calculation would substitute sand dredging for some of the CaCO3 energy use as well as including the energy for the carbon fiber.

The primary cost of building a tropical doldrum Atmospheric Vortex Engine is a huge hollow structure called the "arena" that contains the low pressure created by the vortex. The low pressure is relieved through compact, high speed turbines at the base of the arena. Since the turbines are compact they don't have to be costly and since they are high speed they don't have to be numerous.

What good is a tropical doldrum Atmospheric Vortex Engine?

It can generate its own building material from the ocean and atmosphere -- so if you can print them rapidly you can have rapid doubling time exponential growth in clean baseload electric production that within a decade dwarfs all energy use by civilization.

Oh, and it also provides tropical atoll seasteads sufficient to feed and house the total population of the world.

Seastead this.

Comment Sleep Collects Neural Garbage (Score 5, Informative) 710

They've finally figured out why sleep deprivation kills you -- and its also why it makes you make stupid mistakes.

Sleep Drives Metabolite Clearance from the Adult Brain

Problem is it is mainly during slow wave sleep that the cleaning crew works on the CSF, and as people age they their slow wave sleep diminishes.

Comment Re:Discrimination and the "Free" Market (Score 2) 370

I didn't specify what kind of "discrimination" I am subject to, but it is more than age. I reiterate, I have no complaints about being discriminated against. Indeed, I wholeheartedly support the right of any private entity to discriminate on any basis whatsoever in its associations whether personal or commercial -- and that includes the right of those who discriminate against me even when I perceive their discrimination to be "unfair".

What I oppose is a system of government that taxes anything but property rights to pay for its primary service: the protection of liquid value of property rights (including collective property such as national territory) beyond those an individual would defend in nature (ie: his homestead including tools of his trade as well as any other capital assets such as land).

Comment Floating Atolls (Score 0) 192

Floating atoll remediation of civilization's environmental footprint would, in addition to permanently rewilding agricultural lands and containing all urban population effluent (including CO2, CH4, N2O and CFC emissions) for 10 billion people at higher than US standard of living, sequester on the order of a teratonne of CO2 from the oceans and atmosphere.

The Seasteading Institute is being left behind by AT Design Office under contract to the Chinese construction firm CCCC, as they proceed with the pilot project to build a 10 square km floating city. What the Seasteading Institute has going for them is their association with Breakout Labs via Peter Thiel, as it supports fluid dynamics research for of the Atmospheric Vortex Engine. Although the AVE would be advantageous even with advanced nuclear technology, any radical reduction (less than 1 cent/kWh) in electric cost -- with or without the AVE -- will suffice to enable the rest of the floating atoll remediation. This is one of a few things that Marshall Savage didn't have the technical chops to address -- the other major things being photobioreactor technology and the notion of atolls unifying beachfront real estate demand with wave break for fragile (hence economic) PBRs.

At this point, it appears to be an entirely feasible economic proposition given the requisite lowering of cost for pollution free electric generation.

If the AVE experiments currently underway attest its economy, the Seasteading Institute can take the floating atoll proposal, package it up the way Mashall Savage should have, and present it to the Chinese. They'll bite.
