For solar water heating in your home, there are basically two types of solar collectors: conventional flat-plate collectors and evacuated tube collectors. Evacuated tubes have a number of advantages: the work on overcast days, in colder weather, and the tubes can be installed and replaced individually without special tools.

Made from recycled newsprint, these remarkable and disposable slippers cost less than 50 cents each. The color is natural and no bleaching agents/chemicals have been used — even the cord and the support tube are made from twisted unbleached paper.
Apricus makes a unique solar hot water heater which is 30-40% more efficient than flat plate solar systems. The secret to the performance is the use of cylindrical evacuated glass tubes to absorb the heat from the sun. Because the tubes are cylindrical, there is always a surface area that is perpendicular to the sun.… [Continue Reading]

The tube has an anodized aluminum housing which resists stains and scratches, but weighs in at only two pounds. The speakers are 2”… [Continue Reading]
Cold Cathode Fluorescent lights draw very little power for the light they deliver. CCFs produce up to 80 lumens per watt. Halogen lights typically produce 15-18 lumens per watt, and the most efficient white LEDs on the market produce 23 lumens per watt. CCF lights provide up to 25,000 hours of service life and unlimited… [Continue Reading]
