New Method of Harvesting Wave Energy


For towns and cities in coastal areas, harvesting wave energy makes a lot of sense. The company Albatern from Scotland recently came out with a unique solution for easy and affordable way to do just that. The so-called WaveNET is a modular and scalable array of floating generator units. These units, also referred to as “Squids”, are capable of harvesting wave energy via their buoyant arms that can follow the motion of the waves very precisely.

A team of researchers at the Ohio State University (OSU) successfully produced a dye-sensitized solar cell, which can store power by using air to decompose and re-form lithium peroxide. This device combines a solar cell and battery into one, and it is the first device of its kind. The adoption of this technology could also considerably lower the costs of solar cells.

Stacking Solar Cells Could Vastly Improve Their Efficiency


Harvesting solar energy is a great way to generate sustainable power, but unfortunately solar cells are far from being as efficient as they might be. Currently, commercially available solar cells can convert about 25 percent of sunlight into electricity, and scientists have been trying to create better solar cells for years. One milestone they have been unsuccessfully trying to reach is 50 percent conversion efficiency of solar cells. However, the start-up company Semprius might be on the right track with the stacking technique of solar cells they recently developed.
