The last year has been one of incredible growth for renewable energy. More systems are being installed than ever before. The hardware not only really works, but is cost effective. The word is getting around that RE can provide electricity where the power line can't. Five years ago I figured that a system had to be at least four miles from the grid to make RE cost effective. This distance has now shrunk to about 1 2 mile. According to SERI (the US Gov't. sponsored Solar Energy Research...

Home Power tests the Heliotrope CC-60 PWM Battery Charge Controller Up to now charge controllers have been basically voltage sensing switches. Well, Heliotrope has a new approach to battery state of charge control. Their new CC-60 is a real STATE OF CHARGE controller-far more than just a voltage regulator. The CC series of controllers are very well made and can handle up to 120 Amps in either 12 or 24 VDC systems. This PWM (Pulse Width Modulation) controller is an all solid state, series type...

As a result of your touting Solar Retrofit Consortium's fluorescent valance light, Model 88 SVL, I ordered one. Unfortunately, it arrived, via parcel post, with damage to the fluorescent tube so that it didn't work. I wrote to the company and promptly received a replacement tube via UPS 2nd Day Air. I agree with your praise of the fixture and wanted you to know that the company was also worthy of praise in its considerateness for its customers. Sincerely, Jack Lesh, Gustavus, AK First of all,...

And 120 Ampere Photovoltaic Charge Controllers

The CC-60 is a series Pulse Width Modulated charge controller providing complete and failsafe battery recharging. State-of-the-Art MOSFET technology gives the fullest possible charge by trickle charging the batteries once they reach float voltage. This is not possible with unreliable relay series type controllers. Standard features include temperature compensation, 12 24 Volt selectable, 16 easy to select S.O.C. voltages, remote voltage sensing and low voltage warning. The CC-60 and CC-120 will...

That the structures described above are only one out of many possible views of a dynamically changing matrix. One might be tempted to wonder whether the conclusions invalidate the deductive processes that arrived at them. Not at all. It is explainable as follows. The amount of bound photonic energy of a particle at rest is directly proportional to its bound tachyonic energy. mo (Constant)*(Tachyonic Energy) (c2) It is thus still a proper quantity to be used in the gravitational force equation....

A month will give a good idea of how much power can be expected year round. The 50 efficiency rule applies to sites with heads greater than 30-40 feet or so. At lower heads everything becomes more difficult. Turbine and pipes become larger and speeds of rotation decrease. The diameter and length of pipeline can now be determined once you have an idea of the potential power output of your site. It is assumed that you are planning on using a TURBINE and will generate ELECTRICITY. Other courses of...
