New record energy efficiency for artificial photosynthesis

By
As the world moves towards developing new avenues of renewable energy, the efficiencies of producing fuels such as hydrogen must increase to the point that they rival or exceed those of conventional energy sources to make them a viable alternative. Now researchers at Monash University in Melbourne claim to have created a solar-powered device that produces hydrogen at a world-record 22 percent efficiency, which is a significant step towards making cheap, efficient hydrogen production a reality. Efficiency records for solar-powered hydrogen production have continued to rise over the years, and much more rapidly as the technology and techniques improve. Even as late as December last year  Gizmag reported  a solar-driven hydrogen record efficiency at the time of just 12.3 percent, so this new record shows a very healthy 10 percent improvement on that and beats out the previous record of 18 percent. Splitting water using electricity to produce hydrogen and oxygen has been a...

The Japanese skateboard

By
A Japanese engineer just invented a nifty new way to travel: A transporter called a “WalkCar” that’s small, light and apparently easy to use. The product is battery powered and is about the size of a laptop. And although it looks like it can hold much weight and is made from aluminum, it can apparently have as much as 265 lbs on board. VentureBeat  reported  that it can go up to 6.2 miles per hour for up to 7.4 miles. It needs three hours to charge.

Study claims perovskite solar cells can recoup their energy cost within three months

By
Scientists at Northwestern University and the U.S. Department of Energy have found that perovskite cells, one of the most promising solar technologies of recent years, can repay their energy cost over 10 times faster than traditional silicon-based solar cells. The finding confirms that, once issues related to cell longevity are ironed out, perovskite cells could soon bring us solar energy on the cheap, and do so with less impact on the environment over their lifetime. Solar panel installations are doubtlessly having a positive impact on the environment, but quantifying their carbon footprint with some degree of precision – which is useful for comparing them to other means of energy production, including other renewables – is not a straightforward process. To get a more complete picture, it's important to consider not only the carbon emissions saved during the panel's operating life, but also the amount of energy that goes into materials processing, manufacture, repair, ma...
