China e sua preparacao para o espaco: um bom teste para "ecologistas sustentaveis"

Agora, cada vez que um ecologista vir com aquela conversa fiada de viver consumindo poucos recursos da Mãe Terra (como certa candidata a vegetal semi-presidencial), eu vou mandar ele se inscrever nesse programa chinês de preparação para viver na Mãe Lua.
Sempre que alguém vir com aquele papo chato de respeito ao meio ambiente, não consumismo, equilíbrio natural, já sei para onde tenho de mandar o sujeito.
Direto para a China: vegetais cultivados em sistema autossustentável, insetos, é tudo o que eles precisam para deixar a gente em paz...

105 days in ‘miniature Earth’ raising fruit, veg ... and bugs

By Yang Jian | Sh Daily, May 21, 2014, Wednesday |  PRINT EDITION

THREE Chinese volunteers yesterday ended an experiment that saw them live for 105 days in an enclosed capsule, eating only laboratory-raised plants and insects.

This was China’s first manned test of Moon Palace 1 — Yuegong-1 — a 500-cubic-meter module that is China’s first and only the world’s third bioregenerative life support base.

In a closed lab on the campus of Beihang University, volunteers Xie Beizhen, Dong Chen and Wang Minjuan fed themselves by cultivating grain, vegetables, fruit and grubs.

Featuring a cabin and two plant growing labs, the system also produces water and fertilizer, processes waste and recycles air.

Liu Hong, chief designer of the system, described it as a miniature version of the Earth’s biosphere.

It can help make it possible for astronauts to live safely on space stations for long periods without deliveries of supplies, explained Liu.

The cabin includes living quarters, a room for socializing, a bathroom, a waste treatment room, plus a room for breeding insects for the dinner table.

Two plant cultivation rooms offer different temperatures and levels of humidity.

Liu said the research team cultivated five grains, 15 types of vegetables, one kind of fruit, plus yellow mealworm — providing protein for the volunteers.

The team of 26 scientists began investigating the system in 2004 and all facilities and techniques are domestically developed, said officials.

It is said to be one of the world’s most advanced systems of its kind, providing core technology for manned space exploration.

In the closed system, waste produced by the inhabitants is used to fertilize the soil.

Carbon dioxide produced by inhabitants and insects is used to facilitate photosynthesis, while oxygen from the process is returned to the human cabin.

Some distilled water is collected for drinking, with the remainder plus urine used to irrigate plants.

Last June, three Chinese astronauts spent 12 days in  Heavenly Palace 1 — Tiangong-1 —in the country’s longest manned space mission.

China’s manned space mission has entered its second decade with ambitious plans including building a permanent space station and launching a manned lunar probe.
