How floating turbines could harness the awesome power of the tides
Ross Jennings for The Conversation: The world’s tides contain enough energy to power the entire UK’s electricity consumption. And, since it effectively harnesses the moon’s constant and predictable gravitational pull, tidal power overcomes one of renewable energy’s classic problems – the fact you never know quite how much sun, wind or rain to expect. Now, underwater windmills positioned just below the ocean surface could be a major breakthrough for tidal power.
Costly technology and inaccessible locations have thus far held things back. Large, heavy and expensive turbines mounted on the seabed have been developed, but these are aimed at commercial scale developments. Tidal power needs its equivalent of the rooftop solar panel.
Imagine then a wind turbine, but underwater, and not fixed to the seabed – these so-called “mobile floating turbines” are a cheaper and more adaptable alternative to big, fixed developments. Most floating turbines look something like this: Cont'd...

Concentrator Photovoltaics: The Next Step Towards Better Solar Power
By Lauren J. Young for IEEE Spectrum: Today’s concentrator photovoltaic (CPV) technologies have shown promising potential for more efficient solar power. The latest systems are said to be capable of handling the power of a hundred suns. Yet prototypes have failed to compete with cheaper flat panel solar systems that dominate the market. The U.S. Department of Energy’s Advanced Research Projects Agency (ARPA-E) is determined to push CPV to the next level. On 24 August, at the Clean Energy Summit, U.S. President Barack Obama and Energy Secretary Ernest Monizannounced a program called MOSAIC that will invest $24 million into CPV solar technology development.
Why can’t today’s CPV systems compete? The concentrators can only convert direct sunlight into energy, missing out on the large fraction of sunlight diffracted by clouds and the atmosphere. Manufacturing costs of concentrator apparatuses have also prevented CPV from reaching mass production. Cont'd...
