It looks great and it’s also greener. Designed by Elie Ahovi, “Lit” combines LED (Light-Emitting Diodes) with optical fiber technology.

This means that the bulb will last much longer, besides offering dimmable light quality. It is a much more eco-friendly option to incandescent lights (more…)

The combustion of fossil fuels are a huge health hazard as to a recent United Nations report, 3.3 million people died from outdoor air pollution in 2010. An additional 3.5 million people die early annually from indoor air pollution.

I had noted in a previous Cleantechies article that air (more…)

The cell phone is quickly becoming a handy tool for tracking home energy use and even switching appliances on and off from afar. It also turns out to be a good way for consumers to view the inner workings of the electric grid – as ISO New England is showing.

ISO-NE in September became the first grid operator (more…)

Anyone who discounts what Bill Gates says on any issue has some explaining to do.

In a recent decision the U.S. District Court for the Northern District of Ohio granted AgiLight’s motion for summary judgment on the remaining claims of two patents, U.S. Patent Nos. 7,633,055 (’055 Patent) (more…)

When I got started in this subject a few years ago, the efficiency of thin film solar (i.e., the percentage of sun’s radiant power that is converted into electricity) was measured in single digits. Here, we just achieved 16.1%, a huge increase from the former record holder at 14.7%. (more…)

When it comes to energy-efficient and sustainable elements for the home or office, most people immediately start seeing green (cha-ching!). But while there are plenty of pricey options available for reducing a structure’s environmental footprint — from HVAC upgrades to solar panel installations — you don’t have to give up all of your hard-earned cash to earn (more…)

The so-called “artificial leaf,” a solar cell being developed by MIT and Harvard scientists to produce low-cost electricity, is now capable of “self healing” the damage that occurs during energy production, clearing a hurdle to deploying the device in the developing world, scientists say. (more…)

The worldwide buzz around the revolutionary aluminum-air battery of the Israeli-based technology company Phinergy is reaching new peaks. Even president Obama had the chance to view the technology during his visit to Israel.

Phinergy has created a car battery that powers an (more…)
