We drove to Massachusetts yesterday to visit Tom Leue from http://yellowbiodiesel.com/, and brought back one of his Recycled Vegetable Oil (RVO) burners. This is designed to replace a standard 4″ Beckett burner in a boiler or furnace, can be installed in a drum for a shop heater, used to heat water, or even create steam for a steam engine powered heat and electric application (Combined heat and power, or CHP). We talked a bit a few days ago about this burner in a previous blog article, which gives more info on the burner itself. This design is based on a Babington burner that injects air through a tiny jet in a ball, and pumps oil over the ball, forming a ignitable vapor when the oil covers the jet of air, similar to a whale’s blowhole. Discussions of the Babington principle are commonly held at http://group.wastewatts.org.

Solar energy is our birthright like the air we breathe or the water we drink. Solar Home Plans and affordable Solar Hot Water Plans are the gateway into a “Solar Age” of energy independence. Fossil fuels are no longer necessary to keep the wheels of civilization turning. Build your own solar heating system with an MTD Solar Collector Kit. Explore the Strawberry Fields Book Store for more information. Alternative energies like solar energy will increase in value as fossil fuel prices escalate. Solar collectors, solar hot water systems, heat storage vaults, photovoltaic electricity, solar panels, solar greenhouses and solar house plans will become more important in this century. According to Buckminster Fuller “We have wondered too far from the roots.” An energy crisis can only be avoided only if we learn to rely on a diffuse, sustainable resource like the sun. .
1. Take these energy-efficient measures:
- Replace and recycle your old refrigerator and purchase energy-efficient models. Units only 10 years old can use twice as much electricity as a new ENERGY STAR® labeled model.
- Insulate ceilings to R-30 standards if your attic has less than R-19.
- Caulk windows, doors and anywhere air leaks in or out. Do not caulk around water heater and furnace exhaust pipes.
- Weatherstrip around windows and doors.
- Wrap heating and cooling ducts with duct wrap, or use mastic sealant.
- Install energy-saver showerheads.
2. When buying new appliances, be sure to purchase energy-efficient ENERGY STAR® labeled models.
3. Set the furnace thermostat at 68 degrees or lower, and the air-conditioner thermostat at 78 degrees or higher, health permitting. 3 percent to 5 percent more energy is used for each degree the furnace is set above 68 degrees and for each degree the air conditioner is set below 78 degrees.
4. If your old air conditioner is on its way out replace it with ENERGY STAR® labeled energy-efficient model.
5. Use compact fluorescent lamps. You can lower your lighting bill by converting to energy-efficient low-wattage compact fluorescent lighting and fixtures.
6. Replace old windows with new high performance dual pane windows.
7. Clean or replace furnace and air-conditioner filters regularly, following manufacturer’s instructions.
8. Set the water heater thermostat at 140 degrees or “normal.” If you have a dishwasher. Otherwise, set it at 120 degrees or “low.” Check your dishwasher to see if you can use 120 degree water. Follow the manufacturer’s direction on yearly maintenance to extend the life of your unit.
9. Fix defective plumbing or dripping faucets. A single dripping hot water faucet can waste 212 gallons of water a month. That not only increases water bills, but also increases the gas or electric bill for heating the water.
10. Wash only full loads in a dishwasher and use the shortest cycle that will get your dishes clean. If operating instructions allow, turn off the dishwasher before the drying cycle, open the door and let the dishes dry naturally.
11. Defrost refrigerators and freezers before ice buildup becomes 1/4-inch thick.
12. Install shades, awnings or sunscreens on windows facing south and/or west to block summer light. In winter, open shades on sunny days to help warm rooms.
13. Close the damper when the fireplace is not being used. Try not to use the fireplace and central heating system at the same time.
