Take a tour of a plug-in electric hybrid modification of a 1996 Mercury Sable, with UC Davis graduate students Patrick Kaufman and Bryan Jungers (interviewed in episode 113). Under the hood you'll see modifications and some interesting new components. Unlike commercial hybrids -- primarily combustion engines with an electric-motor assist -- theirs is primarily an electric vehicle with a small combustion engine to extend its range beyond the all-electric 60-70 miles. Batteries recharge in 6-8 hours with electricity costing about 75 cents per gallon of gas equivalent (2006 prices). Don't miss Janaia's first-time drive of an electric vehicle. Episode 114.

Students at UC Davis Hybrid Vehicle Research Center have been creating plug-in hybrids for national competitions for some time. "Team Fate" members Bryan Jungers and Patrick Kaufman describe how they "gut" the drive train of a standard vehicle, replacing it with an electric motor, a bank of batteries, continuously variable transmission, and some clever electronics. The resulting vehicle runs on electricity, assisted by a much smaller flex-fuel internal combustion engine only when needed. Bryan and Patrick also enlighten us on topics ranging from battery technology to hydrogen fuel cells. Episode 113.

Most of Washington State's San Juan Islands don't have grid electricity. Many people have relied on generators, but these days, an increasing number are turning to solar. Renewables installer Eric Youngren discusses how net metering works to pay individual energy producers for power they put back into the grid, and other incentives for small-scale renewable "power plants". He tells us about "run of the river" hydro, powered by diversions rather than dams in creeks. A strong advocate for conservation and efficiency, Eric says we could be running everything in the home on a fraction of the energy we now use, just with rooftop solar. Episode 109.
