The site includes the pulser pump, 15 years working and still not tested by science! and demonstrations of prototypes of devices that it can run. Also, 2 better systems for voting or making a decision. A few checkers like board games for 4 people, an ideas page, reviews of linux and psion and my masonry page fills out the website. Brian White
