Closing the Loop on Energy Use

22 June 2009 - 6:00am

Architect Michael Palwyn is designing sustainable architecture that combines solar power and seawater into an ultra-efficient loop of resource conservation.

"Pawlyn, working alongside inventor Charlie Paton and engineer Bill Watts, recognized that by joining two cutting-edge technologies they could create a facility that would bring water and arable land to the Sahara Desert. The so-called Sahara Forest Project, which Pawlyn has been developing for the last few years, would be powered by a concentrated solar power plant. There, a field of mirrors concentrates the sun’s rays into high-intensity light that’s then used to generate steam, which in turn powers an electricity-generating turbine.

That’s where things get exciting.

Some of that electricity generated would be used to power a Seawater Greenhouse, which Paton invented. The electricity would be used to pump cold seawater inland, to the greenhouse. There, fresh air passes over tubes housing that seawater; the interaction condenses fresh water from the air, which can then be used to grow biofuels and rehabilitate the surrounding desert."

There is lots of theory, and lots of wonderful mathematics, and even lots of dealmaking. But the financial engineers are not real engineers who take responsibility for the bridges that fall down. They have no notion of a safety factor.
