Solar Devices. Heating Homes with Solar Air Collectors (DIY) Solar air heating comes in many different varieties and is surprisingly very efficient!
One manner of heating air with the sun is by using collector plates which absorb the radiating heat from our star, heats the air inside of the collector, and uses this air to heat a closed space. As the website Easy Green Living describes, you can either buy a system or you can build one yourself! This is an extremely simple technology to implement and this article is going to show you how to build one for yourself! The benefits of this technology are impressive: Cheaper or near non-existent heating billsIf the grid goes out you still have heatVery simple to build with little to no upkeep neededPossible to fit directly into existing central air systems Solar hot air collector plates come in two types: Passive Direct Gain or Active Direct Gain.
Passive Direct Gain For a solar collector, to be passive means to have no fans which circulate the air through it. Building A Passive Solar Collector.

Bike lighting is usually a pretty pedestrian affair: a handlebar-mounted headlight and possibly a seat-mounted rear flasher to make the bike visible to motorists.
Palo Alto startup Revolights wants to change that. Their new product, which has just reached three times the level of requested funding on Kickstarter, is a set of LEDs mounted on the wheels of your bike–white in front for a headlight and red in back like a brake light. The cool thing about these lights, besides the fact that they are made with eco-friendly LEDs and make your bike look like a glow-stick, is that they provide illumination on the sides of the bike as well as at the front and back. The white light shows the way forward and alerts motorists of the location of your front bike wheel.
The red back light does the same, orienting the location and distance of your bike for motorists–at least once they know what they’re looking at. + Revolights Via NotCot.

Small Wind Electric Systems. If you have enough wind resource in your area and the situation is right, small wind electric systems are one of the most cost-effective home-based renewable energy systems -- with zero emissions and pollution.
Small wind electric systems can: Lower your electricity bills by 50%–90%Help you avoid the high costs of having utility power lines extended to a remote locationHelp uninterruptible power supplies ride through extended utility outages. Small wind electric systems can also be used for a variety of other applications, including water pumping [10890] on farms and ranches. Our pages on planning for a small wind electric system, and on installing and maintaining a small wind electric system have more information. How a Small Wind Electric System Works Wind is created by the unequal heating of the Earth's surface by the sun. A small wind system can be connected to the electric grid through your power provider or it can stand alone (off-grid). Small Wind Electric System Components Turbines.
