Evaporation energy

http://www.dailymail.co.uk/sciencetech/ … l#comments

I hadn't heard of this evaporation energy technique before now.  Sounds intriguing.  Would presumably need domes on Mars to work.

Re: Evaporation energy

A miniature version of the engine was first developed by scientists in 2015
It could be scaled up to cover 70% of the US's energy production from that year
It could yield between 2W and 10W per square metre, three times wind power

In a 2015 paper, Dr Sahin showed how this basic process can be exploited to do work.

In their 2015 paper, the researchers unveiled the first rotary engine and even a tiny car powered by humidity.

It works using bacterial spore that expand when they become humid to drive an engine.
Inside the bacterial spores, water is confined to nanoscale cavities and depending on the humidity, large pressure changes are induced.

When water is applied, the tape changes its curvature in moist and dry conditions.

When multiple tapes are assembled in parallel they can lift weight against gravity.

The engines start and run autonomously when placed at air–water interfaces.

They generate rotary and piston-like linear motion using specially designed, biologically based artificial muscles responsive to moisture fluctuations.

The bacteria spore and moisture pus any heat to cause motion to happen within a near operating temperature range I would supect....
