Meet “Wave Star” of Denmark. It is a facility designed to convert kinetic wave power into electricity.
Wave Star is equipped with kinetic-energy harvesters called “floats.” The floats move up and down with the kinetic motion of the waves. The motion of the floats is transferred via hydraulics to rotate power generators. Their facility enables continuous energy production and a smooth output.
The full scale device will be equipped 20 floats of 10 m (33 ft) in diameter. Each power station will be able to produce 6 megawatts of energy, a single machine providing enough energy for roughly 4000 homes.
In the event of a storm, the floats can be lifted to a safe position. The facility could also be upgraded to utilize wind and solar power. The power stations are planned to hit the market this year!

A tiny Spanish island with just 10,000 residents is about to do something amazing. El Hierro, the smallest of the Canary Islands, plans to completely sever ties with the traditional power grid and move entirely to renewable energy. The island plans to become completely self-sufficient next month when its 11.5 megawatt wind farm kicks into gear. El Hierro has already got a fully-functioning water turbine with hvof coating that generates electricity, and the added wind power will enable the island to go totally off-grid.
The island actually generates enough power for its residential needs with just the water turbines, but the wind power allows El Hierro to have a little extra power, which will be used to pump fresh water from near the harbor on the island to a reservoir in a volcanic crater 2,300-feet above the sea. This means that those on the island are able to access fixed energy plans, as the costs go towards maintaining this infrastructure. Such plans have made many wonder if prepaid electricity near me is possible with similar systems helping to provide greener energy for larger grids. As for the island, there are failsafes in place for different weather conditions; When there is not enough wind for electricity needs, that water will be released to feed down into the water turbines to generate more energy, so the island will always have enough power to keep things running.
Imagine if more islands are able to farm such energy. Over time and trials of projects like these, we will learn of ways to make building out wind turbines to be more efficient and effective. In a closed environment such as islands this could be rather optimal.

A French company called New Wind is installing tree-shaped wind turbines at the Place de la Concorde in Paris, France. The company’s founder, Jérôme Michaud-Larivière came up with the idea while in a Paris square, when he “saw the leaves tremble when there was not a breath of air.” He hopes the trees can be used to exploit small air currents flowing along buildings and streets, and could eventually be installed in people’s yards and urban centres.
He is the first to admit the efficiency of the trees is low compared to more consistent currents higher up, but believes the £23,500 trees are more viable and less intrusive than ‘monstrous’ conventional wind turbines. The 26 foot high trees, which use tiny blades inside the ‘leaves’, could potentially be profitable after a year of wind speeds averaging 7.8 mph. They can generate electricity in wind speeds as low as 4.5 mph. Visit the link below for more photos and a video.
