Just in from Midtown Brews community member Jeff Hershberger: a suggestion for a 2009 Midtown Brews guest and topic. (A reminder: anyone can suggest topics, guests, or invite students and colleagues, friends and family to Midtown Brews. All topics are suggested by someone in the Midtown Brews community.)
Jeff says..."Paul van der Sluis and he's a Ph.D. materials scientist (or maybe physicist) working for Philips in the Netherlands. I met him at a conference in August. He was there to talk about a third-world cookstove he's developing, which burns wood more efficiently and with less harmful smoke. It uses a thermoelectric generator to power a fan to blow air into the fire."

Jeff continues...
"But I think you'll be more interested in hearing him talk about his carbon-neutral house. I chatted with him during a break and he talked about a number of fairly simple and retrofittable strategies that cut utility bills to a fraction of what they are for most people. For example, he preheats his shower water by running it through solar collectors on his roof. Then he uses the warmth of the shower drainpipe to preheat what goes to the roof! Thermodynamically it makes a lot of sense."
