GridPoint's intelligent energy management appliance manages both traditional and renewable energy to reduce costs - and also provides clean, silent and automatic backup power.
The effectiveness of composting is not in any doubt and the benefits are numerous including the fact that the product produced can provide for very fruitful organic farming.
A computer-linked weather station offers not only real-time display of weather measurements on your computer monitor, but also provides for advanced data collection and graphical weather analysis.
Radiation is how the sun heats the earth, as there is no air between the two. Radiation is usually far more efficient than convection and the air movement is minimal.
A programmable thermostat can save you money on your utility bill - up to 33%, if used as directed. You set it up to adjust the temperature when you are away from home or asleep.
Even at the risk of losing some business, we are committed to adapting alternative materials that will ultimately help preserve the environment while offering high quality, more affordable products that add beauty to the home without accelerating the loss of our natural resources.
The key strength of LED lighting systems is in their low power consumption and durability. On average led based lighting systems will use 10%-20% of the power consumption of their incandescent counterparts.
When buying a clothes washer, it can be helpful to think of two price tags. The first price tag is the price paid to purchase the washer. The second price tag is the cost to operate the washer over its lifetime.
Tips on using and enjoying manual reel mowers.
Zonnewater developed a desalination unit based on solar energy (95% thermal and 5% photovoltaic or wind energy), suited for coastal areas with an average temperature of 30 degrees Celsius. The prototype is a small one cubic meter greenhouse-type construction that produces 40 litres of water per day.
Apart from the small electronic component the whole installation can be made locally with materials available in nearly every part of the world, being glass and PVC piping and appendages.
Inverters convert the "DC" electrical power output of renewable energy technologies - such as solar, wind and fuel cells - to the high quality "AC" that our conventional power system require.
SEADOG is a "point absorbing" wave energy converter designed to extract a small amount of energy from a portion of the wave front as the wave passes by, as opposed to other wave energy designs that attempt to extract large amounts of energy but may terminate the wave in the process.
The concept of radiant heating is to warm walls, objects, and people which in return warm the air creating ultimate comfort at lower room temperature.
CANMET tests have shown that this renewable biomass fuel log produces 94% less CO and 84% less Particulate Matter emissions than cordwood.
