On this week’s podcast I spoke with Bob Jennings, an engineer who specializes in alternative heating systems. In his view, the sun and the forests are major sources of practical renewable energy for New England’s near future. He designs and installs solutions based on solar hot water, and also on wood gasification boilers like the one whose installation and use I described here.
Most experts agree that we’ll need to replace oil with a mix of renewable sources. In regions where wood biomass is an important ingredient in that mix, we’ll need modern technologies that burn the stuff cleanly and efficient. Bob Jennings reflects on existing and emerging options: pellet stoves, pellet boilers, and wood gasification boilers.
