1. Tilted wick type solar still is one of the effective plants utilizing solar energy for seawater (or brackish water) desalination.

2. A heat and mass transfer relation in a solar still was established and the steady state simulation experiments in a multi stage stacked tray distillation chamber were conducted.

3. Biofuels as well as wind and solar still need energy prices to be high to help them claw their way to profitability.

4. A method for calculating the efficiency of solar still and a view of using performance curves for rating thermal performance of solar stills are presented.

5. How he ingeniously managed to catch fish, how he fixed his solar still, which evaporates seawater to make fresh water, is very interesting.

6. I'm told credit is still tight, especially in the U.S. Solar still depends on attractive subsidies. That still concerns me.
