We did a piece on USFR this weekend about windmills. And then today I ran across this:
Everyone knows the KISS principle, but too often it’s forgotten in an effort to build new gadgets. Typically, desalination requires large amounts of electricity, and operates at a low efficiency. Now, researchers from (where else) the Netherlands have skipped the electrical middleman and are using the mechanical energy created by a standard irrigation windmill to force water through a special reverse osmosis filter.
This will produce around 5-10 cubic meters of water, or roughly enough to satisfy 500 people, with a storage reservoir to save up for windless days. The prototype should be up and running soon on the Caribbean island of Curaçao. No word yet on when Los Angeles will get the 26,000 it needs to avert a crisis soon. [More]
