Kite Power Harnesses Unspooling Motion For Energy

Kite Gen is pioneering a revolution on how to produce clean energy from wind, with the aim not only to compete within the current wind industry but, as still too rarely happens with renewable sources, to move the battlefield into the territory of fossil fuels.

Instead of harnessing wind power to turn blades tethered to a pole, the KiteGen simply harnesses that rapid unspooling motion of kites reeling out as they release upwards. So instead of a heavy static structure this is simply a light and flexible kite.

The KiteGen would hover at 2,600 feet to produce power each time the kite’s tether unspools, spinning an alternator that generates the power. When the cables are completely unwound the production phase ends, the cables are reeled in to start another production phase. The cycle repeats; like in a yo-yo in reverse.

So the KiteGen splits the components of wind power. In the air; nothing but high efficiency air foils. On the ground, all the heavy machinery for power generation. Connecting the two; high resistance lines transmitting the traction of the kite.

The company holds more than 20 international patents and plans a demo by the end of 2010. These guys are thinking out of the box. They point out that there is about a GW of wind potential in the unusable no-fly air space around nuclear power plants. They suggest that’s the perfect spot for their 2,600 foot kite.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
