How to Build a DIY Savonius Wind Turbine

Arsenij Percov — Thu, 12 Jul 2018 04:23:06 +0000

Here’s a design of a Savonius vertical axis wind turbine developed by a group of people and posted on Instructables under the username lisa-torstenson. Their goal was to create a wind turbine that would be stable and resilient. Almost all of their materials were recycled or reused. Step 1: Gather Materials Since the goal was to […]

New School of Fish-Like Vertical Axis Wind Turbine Boost Energy Production

Mila Luleva — Wed, 17 Jul 2013 12:09:43 +0000

Small vertical-axis wind turbines, organized in the same manner as schools of fish, are found to boost wind energy production, while occupying much less space. When placed in a close proximity, traditional wind turbines are known to interfere with each other. Although the designs have gone through major improvements over the years, the lower efficiency […]

Seven vertical axis wind turbines have been erected at the Olympic Park in London. Instead of building one big wind turbine, as it had initially been announced, the authorities instead built seven smaller versions, but ones adapted to low-speed city winds. The turbines have been announced to have the capacity of 8 kWh each and […]

Efficient Vertical Axis Wind Turbine Concept by Sauer Energy

Ovidiu Sandru — Tue, 28 Sep 2010 14:46:34 +0000

Vertical axis wind turbines have recently been revived by a few innovations made to them by scientists all over the world. Sauer Energy is one of them, and their turbine has a high efficiency because it's designed to maximize the drag, so the blades are moved more efficiently by the wind.

Solar Tree – An Artificial Tree to Produce Clean Electricity from Wind and Sun

Mike Sandru — Mon, 21 Dec 2009 18:44:41 +0000

The leaves of the tree are connected to a vertical-axis wind turbine. Every leaf has a grouping of high-efficiency photovoltaic solar cells that transmit electricity down the tree's core. The solar cells are connected from the upper turbine to the trunk through wireless energy transfer by induction.
