Energy trees by NewWind and nice looking solar roof by Tesla. Clean energy for the future available today.

 

Energy trees

In The Green Energy Blog you can read about very hopeful news.  A tree that looks like a piece of modern art provides the town with clean and renewable energy. Each tree has a current power output of 3.1 kilowatts, which might not be able to power much on its own. However, using several of the trees together, they can supply the surroundings with energy.

The trees are 11 meters (36 ft) tall, and 8 meters (26 ft) in diameter at its widest point, which makes it about the same height as many urban trees. The white frame of the tree is made out of steel, and it can hold 72 turbines that sit vertically. This orientation cancels out noise, allowing the turbine to spin silently. Wind turbines are typically very tall in order to reach the altitude where the wind is stronger, but these vertical turbines are able to spin with wind blowing as low as 7 km/h (4.4 mph), making this twice as sensitive as traditional turbines. However, they are durable enough to withstand Category 3 winds, which can reach 178 – 208 km/h (111-129 mph).

Each turbine “sheet,” called an Aeroleaf, is constructed out of lightweight plastic. The plastic has been treated with a resin which protects it from weather conditions such as humidity and salt (for areas close to the sea). The turbines are wired in parallel so that if one stops working for whatever reason, the others will not be affected.

The energy of a wind tree can supply 83% of the electrical consumption of a French household, excluding heating or loading an electric car for 16 000 kilometer per year.

Nice looking solar roof by Tesla

Tesla founder and CEO Elon Musk wasn’t kidding when he said that the new Tesla solar roof product was better looking than an ordinary roof: the roofing replacement with solar energy gathering powers does indeed look great. It’s a far cry from the obvious and somewhat weird aftermarket panels you see applied to roofs after the fact today.

The solar roofing comes in four distinct styles that Tesla presented at the event, including “Textured Glass Tile,” “Slate Glass Tile,” “Tuscan Glass Tile, and “Smooth Glass Tile.” Each of these achieves a different aesthetic look, but all resembled fairly closely a current roofing material style. Each is also transparent to solar, but appears opaque when viewed from an angle.

Tesla’s product improve the cost of the home , by generating enough energy to fully power a household, with the power designed to be stored in the new Powerwall 2.0 battery units so that homeowners can keep a reserve in case of excess need.
