Michael Reynolds had a dream. The architect wanted to build completely self-sufficient houses that are part of the environment, rather than a burden on it.

An ideal home would be made from recycled materials, maintain a comfortable climate, generate sustainable power from renewable sources, treat its sewage, and provide clean potable water, as well as food, for its inhabitants.

He built his first ‘Earthship’ in 1972 almost entirely from empty soda and beer cans and rammed earth. Now he is the prophet of a movement that advocates “radical sustainability.”

Today, a 634-acre subdivision near Taos, New Mexico, dubbed the ‘Greater World Community,’ is dotted with off-grid homes based on his designs. Meanwhile, an Earthship Academy has opened to teach people from all over the world how to build homes and other buildings based on ‘biotecture’ principles.

Earthships are not without controversy. Their designs have fallen foul of the authorities for violating building codes, and some owners have complained their homes have not performed as advertised. Meanwhile, some places have banned off-grid living altogether.

Follow RTD filmmaker Alexey Brazhnikov as he meets Michael Reynolds and visits some of these amazing structures and their owners in the documentary Earthships.

How we can turn the cold of outer space into a renewable resource | Aaswath Raman

What if we could use the cold darkness of outer space to cool buildings on earth? In this mind-blowing talk, physicist Aaswath Raman details the technology he’s developing to harness “night-sky cooling” — a natural phenomenon where infrared light escapes earth and heads to space, carrying heat along with it — which could dramatically reduce the energy used by our cooling systems (and the pollution they cause). Learn more about how this approach could lead us towards a future where we intelligently tap into the energy of the universe.

Breakthrough in renewable energy – VPRO documentary – 2016

It’s not in the papers but a silent revolution is moving across the world. Renewable energy is becoming cheaper than from fossil fuels. It means that progressively the choice for wind and solar energy is no longer an ethical one but an economic one. And this will speed up the transfer to renewable energy.

In countries like Brazil, Australia, Chile and parts of the United States people consider renewable energy because of financial reasons. The price of solar and wind energy will continue to drop and in more countries renewable energy will occur.

A surprising newcomer on the market is Morocco, where the government expects that in 2020 more than 40 percent of the energy could come from solar energy.
