Here is an intesting solution to extraction power from http://www.oceanpd.com/"

The machine is a semi-submerged,articulated structure
composed of cylindrical sections linked by hinged joints.
The wave-induced motion of these joints is resisted by
hydraulic rams,which pump high-pressure oil through
hydraulic motors via smoothing accumulators.The
hydraulic motors drive electrical generators to produce
electricity.Power from all the joints is fed down a single
umbilical cable to a junction on the sea bed.Several
devices can be connected together and linked to shore
through a single seabed cable.

Well, I was thinking of areas where the wind is not good enough for a wind turbin to be efficient. From what I've heard, the energy from a turbin blade is proportional to the cube of the wind speed. In areas where the winds velocity is not too good for turbins but where there are gust, maybe some bending in a tower (maybe with some oscillation) might achieve some energy; better than a prop turbin.Integral said:To have anything you would have to beat the efficiency of the current wine turbine.
Would it make any sense to drive a hydraulic pump with a wind turbine?
Integral said:Danger,
So you can access the site but none of the information? To bad, this looks like a pretty cool device... But then you live somewhere in the midlands of Ca so may not appreciate it so much being 2000mi from an ocean!
My first thought was that the first good storm would tie it in knots, but then I saw the dimensions. The pontoons are 3.5m in diameter and 120m long and weigh ~3tons. It would take pretty severe weather to bother them.
Alternative energy refers to any energy source that is not derived from traditional fossil fuels, such as coal, oil, and natural gas. It includes renewable sources like solar, wind, hydropower, geothermal, and biofuels, as well as non-renewable sources like nuclear energy.
Alternative energy is important because it offers a cleaner and more sustainable alternative to traditional fossil fuels. Fossil fuels contribute to air and water pollution, as well as climate change. Alternative energy sources can help reduce these negative impacts and provide a more reliable and long-term solution to our energy needs.
There are many benefits to using alternative energy, including reducing our carbon footprint, decreasing our dependence on fossil fuels, and creating new job opportunities in the renewable energy sector. Alternative energy sources are also typically more cost-effective and have a lower environmental impact compared to traditional fuels.
One of the main challenges of implementing alternative energy is the initial cost. Many renewable energy sources require significant upfront investments in infrastructure and technology. There may also be difficulties in integrating alternative energy into existing energy grids and infrastructure. Additionally, the intermittency of some renewable sources, such as solar and wind, can pose challenges for meeting energy demand.
Individuals can support alternative energy by making small changes in their daily lives, such as using energy-efficient appliances, carpooling or using public transportation, and investing in renewable energy programs. They can also advocate for policies and legislation that promote the use of alternative energy sources and reduce our reliance on fossil fuels.
