We can affect our own and the larger environment by our choices of lighting systems and by how we use them. Depending upon our personal assessments of the risks involved we might use conventional incandescent or halogen lamps for study or work areas where the lamp will be near the user. We could also utilize efficient fluorescent lamps in outdoor or more remote locations that need low cost, long-lasting illumination. Using only the needed amount of light for the task is basic and wise. We might...

More Than Enough

You first see the large yellow water tank, turn right and follow the abalone shell lined driveway to a place full of character and inhabited by one. Stuart Ward's small, owner-built cabin sits on the juniper flats below the north face of California's Mt. Shasta. His two photovoltaic panels and two lead acid batteries supply more than enough power for his lifestyle. Stuart Ward built his cabin over four years, from 1979-1982. The cabin is 16 feet by 28 feet with a main floor of 448 square feet...

Fig. 1- The Power Content of Pulse Trains This illustration is a graphical representation of the pulse situation. The vertical axis of the graphs represents voltage, while the horizontal axis represents time. The Section marked A shows the switch in the always ON, i.e. a duty cycle of 100 . The power of the pulse train is represented by the shaded area of the pulses. Section B illustrates the OFF condition, where there is no shaded area as the power is always OFF. Section C shows a pulse train...

Automagic Battery Watering

WE MAKE WATER FROM YOUR GAS Hydrogen and oxygen battery gas catalytically recombined into pure water and returned to each battery cell.

Watt-Tester turns any Voltmeter into a Wattmeter The benefits of knowing more about what really runs our electrical world watts of power go largely unknown because of the difficulty in measuring them. Volts and amps are easy, but watts are new territory for many. You can't troubleshoot or search out your system's 'lost watts' if you can't measure them. Knowing actual output power can also help you better select used modules. Low cost becomes high cost if power is lacking, regardless how well...

Total Energy Consumption in W-hrs. day 7136 Total Energy Consumption in W-hrs. day 7136 Our total systemic power consumption is about 7,000 Watt-hours per average day. One of the problems we have faced in our system is that we rarely have an average day. While our household needs are relatively constant, our business power use is very binge oriented. Just before an issue of Home Power goes to press, the computers run from 16-24 hours per day. After the issue goes to press and its mailing is...

The Next Generation

Kids definitely knew their place at the Midwest Renewable Energy Fair MREF in Amherst, Wisconsin this year. A look around the fair saw young faces, bright with curiosity and eyes lit with creative energy. The Home Power crew joined the third annual MREF the third weekend in June. I take no credit for the arduous 45 hour drive the rest of the Home Power crew endured to get to the fair I flew out a few days early to visit Minnesota relatives . This was the first MREF for me and I was quite...

An End of Innocence

Electric racing was forever changed one hot April Sunday at Phoenix International Raceway. The accident happened just past the grandstands, where a few hundred sat in the available patch of shade. During the final event of the Solar amp Electric 500, the lead car, number 99 from Solectria, began to trail a smear of yellow fluid and vapors. It spun and came to rest not quite off the track. Driver James Worden struggled out of the car and collapsed on the ground. The other cars stopped and soon...
