Interesting article from Scientific American about a New Jersey man who has converted his house (and his car) to be completely self-sufficient in terms of energy. No more gas (natural or gasoline) or electric bills for him.
It's not cost-effective (yet) but gives us a working example of what can be done with today's energy-efficient technology.
"Mike Strizki has not paid an electric, oil or gas bill—nor has he spent a nickel to fill up his Mercury Sable—in nearly two years. Instead, the 51-year-old civil engineer makes all the fuel he needs using a system he built in the capacious garage of his home, which employs photovoltaic (PV) panels to turn sunlight into electricity that is harnessed in turn to extract hydrogen from tap water.
Although the device cost $500,000 to construct, and it is unlikely it will ever pay off financially (even with today's skyrocketing oil and gas prices), the civil engineer says it is priceless in terms of what it does buy: freedom from ever paying another heating or electric bill, not to mention keeping a lid on pollution, because water is its only by-product."
