Child's play: Underwater kites fly deep under the ocean and turn the sky green

This article was originally written for Cooler Planet, Media Piston's client, who requested an article about Green News.

I bet you have never seen this kind of Kite

The sky has never been greener. Minesto, a Swedish company specialized in converting tidal currents into green energy, has created undersea kites that will expand United Kingdom's green energy. Called "Deep Green", this project has ambition of amplifying UK's power supply by 1% by 2020, but if the projects goes well, this kind of technology could provide the country up to 5% of their technology in the future, Minesto's press release states.

Although skeptics comments in Minesto's Youtube video question the idea, stating that it may not generate enough energy or threaten Marine life, or be threatened by algae comments both at Youtube's link and Daniel Carrington's blog (the head of the environment section of British news portal "The Guardian", pro-tidal visitors state that "the device is noisy, and unlikely to attract Whales and Sharks", that the device can be made algae-resistant either "chemically or electrically", and that tests could be made in a few areas to ensure this device can be redesigned not to harm marine life, if needed. It's also worth noting that the project has been under development at least as early as 3 years ago, as reported back then by Clean Technica, another news site about green energy.

A fact, however, cannot be denied: United Kingdom's government is not going to give up the idea anytime soon. RenewableUK Wave Tidal 2011, for instance, states that "the UK is already the global leader of wave and tidal energy", which is being held today, as of March 2nd, 2011. This event will discuss the technology's future, which is heavily competing with alternative energy sources as renewable gas technology, solar panels, recycled landfill gas, and wind turbines (which, among them, one that deserved praise, according to Clean Technica, is the AeroEnvironment Architetural wind, capable of adapting to urban areas and architeture and "producing 28,000 Kw/hour under normal wind conditions".

Despite the challenges renewable technology has to face, any new, renewable green technology is welcomed. Oracle ThinkQuest Education Foundation, for instance, states that as of now, ways to permanently handle nuclear technology – one of the major energy alternatives to coal today, are not satisfactory, as it usually takes thousands of years for nuclear energy to be fully decomposed. Therefore, extracting energy from the ocean can prove to be a great source of energy – even more reliable than, for instance, wind technology, as wind currents are not always reliable.
