The article informs that in the northernmost reaches of Scottsdale, Arizona, Bryan Beaulieu, an engineer and inventor with 20 patents in structural systems, recently built a $2 million solar-and-hydrogen-powered "dream" house. This is the opposite of a fossil-fuel-dependent lifestyle, says Roy McAlister, president of the American Hydrogen Association in Mesa, Arizona. And that lifestyle jeopardizes billions of people and creates inflation, pollution and conflict. The design of the Beaulieu house is based on a Navajo hogan. It is one of the only hydrogen houses in the world and complements the so-called "Angels Nest," Robert Plarr's solar- and wind-powered home in Taos, New Mexico. Beaulieus solar panels convert sunlight into electricity, which runs the electrolyzer, a washing-machine-sized appliance that separates hydrogen from water. The hydrogen is then stored in high-pressure tanks, and a generator turns it into electricity for daily needs. And burning hydrogen for fuel cleans the air of pollens and gases better than forced air systems, says Beaulieu.
