Well, listen up folks This one's for you God knows what sort of military machinery this panel was part of, but it originally ran on 24VDC. This charge control panel is just what it says it...

pressure. See the illustration. This one cell electrolyzer along with this simple three foot hydrostatic control will give pressurized storage of both hydrogen and oxygen with no moving parts. The pressure is obtained from the weight of the three foot water column. This is sufficient pressure to displace the water from the bottom 55 gallon barrel to the top barrel. The water in the top barrel in turn puts pressure on the gas. A series of 55 gal. drums can be lined up in this fashion to store...

Things that Work 1
Folks wanting to do a wind site analysis are usually stunned by the cost of recording anemometers. Wind odometers or recording anemometers start at around 350, but most cost 1,200 and up. That's affordable for a wind farm, but what, you may ask, is available for the homeowner For years, I tried to find affordable wind recording equipment. I finally stumbled onto the Wind Odometer made by Trade Wind. I have many expensive wind recording instruments, so I was skeptical when I found this budget...

Things that Work
Some devices set new standards for performance and value. This new PowerStar inverter is such a device. The UPG series inverters are the slickest way to make 120 vac out of battery power that I have ever used. It is powerful- 1,300 Watts continuous with surge capacity to 6,000 W. It is very quiet- both to the human ear, and to radios amp TVs. It is efficient- between 89 and 98 by our testing. The PowerStar UPG revolutionizes inverters. The PowerStar UPG1300 arrived in fine shape in a small box....

The price of the 400 watt UPG model is 399. The 700 watt UPG model costs 499. The 1,300 watt model we tested costs 799. At about 620 per continuous output watt, the UPG 1300 sets a new low price record for inverters. PowerStar's warranty for the UPG inverters is two years. We really like this inverter. The unique operating features of this inverter will revolutionize how we design and use our systems. We most highly recommend it to Home Power readers. Authors and Testers Richard Perez amp Bob-O...
Powerstar Upg1300
600W Microwave amp 760W Shopvac amp 300W Bulbs The UPG series has a smart fan. Most inverters use a thermal switch to turn on the fan. The UPG uses current operated logic to activate the fan. This means the fan turns on BEFORE the inverter gets hot, instead of after. The efficiency of this inverter is very high. Especially at low output wattage. While 60 Hz. transformer based inverters have this same high efficiency around full power, they are very inefficient at low output power. The PowerStar...
Powerstar Upg Inverter Test
inefficient to keep an inverter operating all night just to power a phone answering machine or other small 120 vac load. The UPG inverter is going to change the way systems are designed and operated. After such a successful user test, we couldn't wait to stick it to this inverter. Bob-O Schultze came to Home Power central to witness the event. We lined up all the monster loads, broke out the two Fluke 87 meters, and proceeded. We used a 0.5 precision shunt 50 mV. at 200 Amperes in series with...
The Schatz PV Hydrogen Project
Many of us dream of more efficient ways to store the power we make from renewable energy sources. Here's a system that uses sunlight to make hydrogen and oxygen gas. These stored gases are converted directly into electricity by a fuel cell. Sound futuristic and impossible Well, it's happening at Humboldt State University in Arcata, California. An opportunity we couldn't refuse I recently attended a conference on energy conservation at Humboldt State University. One of the conference's...
