Its an idea that makes perfect sense, when you think about it. Why not use solar power – radiant heat energy – to melt ice from streets and power street infrastructure – street lights, roadway signs, etc.? Researchers at the University of Rhode Island are developing ways to harness solar energy – in particular, the [...]

When you think of jellyfish, what comes to mind? Renewable energy? Probably not, but researchers have discovered a way to get solar power from jellyfish. Jellyfish are some of the Earth’s most ancient organisms – even older than sharks. Floating through the oceans without any internal organs, the creatures can reach sizes of more than [...]
The word of the day is “heliotropic.” That’s a fancy way of describing something that has the ability to track the movement of the sun across the sky, from east to west. Leonardo da Vinci first discovered heliotropism in plants, hundreds of years ago. Today, solar technology has advanced to maximize the amount of energy [...]
For most of us, switching to solar energy is usually a question of cost. Most people and businesses can make the transition from fossil-fuel based power with the help of rebates and falling solar panel costs. If you don’t want to purchase panels outright, you may want to consider a solar panel lease or solar [...]

Most photovoltaic solar cells can only hope to achieve about 15-20% efficiency. Much of the solar energy that strikes the cells is either reflected away or lost as heat energy. But solar collectors at Kalahari Greentech have achieved 74% efficiency. The energy company that specializes in solar technology and wind energy research had its solar [...]

How do you keep your home warm during winter months? Many of us (yours truly included) have a natural gas powered forced air furnace. In fact 35 million American homes use some type of forced air heating system that runs on either propane, natural gas or fuel oil. But what if you could heat your [...]
New solar tracking technology from Envision Solar International has been installed as part of a solar parking array. Heliotropic solar panels track the movements of the sun as it travels across the sky during the day. Environ Solar’s Solar Tree® with EnvisionTrak™ has been directly incorporated into the structure of the parking lot canopy. This [...]

Have you heard of GoSolarUSA‘s PREE™ technology, which uses wireless Internet signals and solar energy to continuously charge smart phones? PREE stands for “Providing Reliable Energy Everywhere.” And that’s just what it promises to do. You may not need to remember to plug in your smartphone ever again! According to the press release published on [...]

At the University of Texas at Austin, researchers are working on solar technology that has the promise of increasing solar cell efficiency from the current 30% conversion rate, up to over 60%. Scientists have been advancing new research on semiconductor nanocrystals, or quantum dots, that can be used in photovoltaic panels to trap some of [...]
