Storing Solar Power In Molten Salt

Solar power is a truly efficient source of energy, but it tends to fluctuate, and, as you might know, it turns off at night. One clever way to alleviate this intermittence is to store solar energy in the form of heat using molten salt. An aerospace company, Hamilton Sundstra, has created a venture called SolarReserve, and it plans to have …

Stunning Solar Building Will Generate More Power Than It Needs

The Masdar Headquarters building will produce more power than it needs (an energy positive building). In fact, the solar roof (one of the largest in the world) will be constructed first, and it will power the construction of the rest of the building. The video link on this page has a great view of the sun-infused interior.

Solar Film Debuts: Cheapest Solar Panel In The World?

Nanosolar has just announced that, after five years of development, it will be shipping its innovative “solar film” product. Basically, Nanosolar is able to print solar panels on machines that resemble printing presses. The company, whose backers include Google’s co-founders, say it is producing the world’s lowest-cost solar panel, costing as little as 99 cents per watt.

The Most Efficient Humidifier: Areca Palm

It’s important to keep indoor humidity at an optimum level (45 to 65 percent). Dry air in the winter  is one the main causes of sinus infections and sore throats. You can use a mechanical humidifier to add moisture to the air, but these devices require constant cleaning to prevent the growth of microorganisms. An easier way to add humidity …

LED Bulbs Could Light Homes In Less Than Three Years

LEDs lights are very efficient, but because of their structure, much of the light in standard LEDs becomes trapped, reducing the brightness of the light. Because of this, LEDs are only useful for “task lighting” in the home — as floor lamps and desk lamps. Now researchers believe they have found a way of introducing a new generation of LEDs …

Liquid-Filled LED Bulbs: 360 Degree Light

I’ve been testing a new LED bulb called the HydraLux. These unique bulbs are filled with a clear liquid coolant (a non-toxic paraffin oil). Other LED bulbs use large metal fins or fans for cooling purposes. The advantage of using a liquid coolant is that the LED bulb can produce 360° light like a regular incandescent bulb.

Reduce Your Household Water Use Efficiently

Reducing household water usage has big-time benefits for both homeowners and for the environment: reducing strain on local water resources, cutting demand on wastewater treatment facilities, and lowering both water and sewage utility bills, to name a few. Although this is by no means an exhaustive list, we’ve put together a collection of water-saving tips and products that can help …

Falcon Wind Turbine: Versatile & Efficient Power Generation

Innovative Windpower AG, a German manufacturer of wind turbines, has developed the Falcon 1.25 MW model to be the most efficient and versatile wind turbine ever created.  It is designed for use in challenging new locations as well as existing wind farms, with substantial advantages over competitors in both its construction process and operation.

Wind power is breaking new records in Spain, accounting for just over 40 percent of all electricity consumed during a brief period last weekend. As heavy winds lashed Spain on Saturday evening wind parks generated 9,862 megawatts of power which translated to 40.8 percent of total consumption. Between Friday and Sunday wind power accounted for an average of 28 percent …

Spin Dryer From Laundry Alternative

A spin dryer is an appliance that can readily improve the energy efficiency in your laundry. A portable spin dryer like this one from Amazon, uses centrifugal force to dry clothes. The dryer was out of stock for a while, but it is now available again. Spin drying is much more efficient than electric tumble drying, in terms of energy …
