You don’t need to travel far in the Dutch countryside before you come across a traditional windmill. Now a consortium of Rotterdam-based companies are planning to build a massive wind-powered generator structure in Rotterdam harbor that will generate energy without using rotating blades. The innovative ‘Windwheel’ will work on the EWICON (Electrostatic WInd energy CONverter) principle developed at TU Delft and Wageningen University backed by a government economy/ecology innovation program.

The striking design has no moving parts but will use wind power to move charged particles (water droplets in this case) against the direction of an electric field. Charge will be transferred to a plate and then fed into the grid. Plans for the proposed generator structure are ambitious and indicate that it will contain a 160-room hotel built on seven floors, 72 residential apartments, a restaurant and other visitor attractions including an outer glass and steel ring structure containing viewing gondolas.

I have something with the weather. I always like to know how warm or cold it is, how much rain has fallen, how hard the wind blows and from what direction,… and so there are lots of sensors around our house to keep me up to date. These sensors give only a limited range of data, so I still need the internet to inform me about everything I want to know.

A simple charge controller suitable for wind or solar applications. Uses a TL-084 Op Amp, automotive spotlight relay and a handful of other components. The same circuit could also be used as a low voltage cut off to disconnect your battery before its fully discharged. Suitable for 12 and 24v operation.

The controller uses two trimpots to set a low and high switching voltage. When the applied voltage ( battery ) exceeds the high voltage setting, a relay is turned on. The relay will remain on until the applied voltage drops below the low voltage setting.

My project is about a wind vane that provides wind direction via a digital output utilizing an LED configuration.The objective is to create an LED configuration were only one LED would light up, showing exactly the direction of the wind vane.

In this project, we’ll build a small, vertical-axis wind turbine, or VAWT for short. These are not as efficient as their horizontal-axis cousins, but they are better suited to urban environments where wind can come from all different directions.

The Zoetrope is a vertical-axis wind turbine made from common materials such as stove pipe, metal brackets, plastic sheet and a trailer hub. Many of the materials can be found at local hardware or home improvement stores, the rest can either be made at home or purchased online.

This project shows how to build a wind generator using common materials.

Wind power is abundant, clean, inexpensive and easy to do. It is our belief that anyone can be in control of where his or her electricity comes from. There is nothing more rewarding and empowering than making a wind powered generator from scrap materials.

This is a simple interface to the windmill power storage. There is a button that the user toggles to get the current voltage and percent charge on the stored energy in the windmill battery(s). to conserve power the unit is controlled by a toggle switch rather than always be on; we work hard to generate that power – no point in throwing it away.
