Animal-driven Electricity Generator

There is an increasing interest and urgency to develop and exploit any possible source of renewable energy which may be applied to the benefit of communities, particularly in remote areas where grid electricity is not available. Systems which generate such electrical energy are particularly attractive, because of the flexibility of application, cleanliness and storage capability of generated electricity.

The prime mover will be an animal, which could be a bull, ox, cow, horse, donkey or mule. The draught animals are capable of working between 3-6 hours per day. The optimal rate has been achieved at drawing speed between 0.6-1.0 m/sec., while the corresponding forces lie between 30 kg and 90 kg. The power output lies between 0.25 kW and 0.56 kW, depending on the animal.

Human Powered Generation - Seesaw

The idea of human powered generation has been implemented in many different situations. Some examples include hand-crank radios, shaking flashlights, and receiving power from gym equipment. The use of playground equipment for a clean source of energy would harness the seemingly endless energy of young children. It would provide them a means to exercise while unknowingly supplying power.

Harnessing human energy on a larger scale and applying it to our current power system has been in development in recent years. One example that is very tempting is using exercise equipment to power gyms. By taking the energy that people pump into stationary bikes, rowing machines, and other equipment, a gym could become self-sustaining or even provide power to a power system. A lot of exercise equipment currently runs off the power that the person working out puts in, but if the extra power not used by the equipment could be input into the building, a lot of extra power could become available.  Contact us for more details

Tractor-Mounted Go Anywhere Generator

This tractor-mounted generator makes it easy to take electric power to anywhere on the farm. The 5,000-watt unit is mounted on a bracket at the front of a tractor driving it with two belts off the tractors side pulley. One horsepower equals 0.75 kilowatt (kW), so you can multiply your tractors PTO horsepower by 0.75 and get an idea of the maximum size generator your tractor can handle.

By mounting the unit on the front of the tractor, you are able to leave the rear end of the tractor free. Also, the generator is always ready to go at a moments notice. The generator platform on front of the tractor slides back and forth to tighten the drive belt.  

Small Wind Turbines

A permanent magnet generator is a perfect choice for small wind turbine applications. Our permanent magnet solutions guarantee high efficiency. Our engineers assist in application engineering to fit the units to the working environment. Our permanent magnet generators for wind turbines cover a range from 1 to 500 kW. Axial flux or radial flux technology is chosen according to the power/torque required. There are models for both horizontal and vertical applications. Engineering support is available also for an integrated solution, where the turbine and the generator work as one unit.

Micro Hydropower Plants

In many areas micro-hydropower has proven to be reliable with usually continuous availability of power and low maintenance requirements. Higher head sites (above 20m) are advantageous because power can be extracted with very compact and therefore cheaper machines such as Pelton turbines. However, the majority of pico-hydropower sites in use globally are low head sites (1-10m head) and the greatest scope for future small hydropower development is through low head sites. Definitions for pico-hydropower vary, but the term generally refers to systems below 5kW in size which can be shared between many households in a community. Choosing a generator for a specific application is governed by a number of factors such as the prime mover speed, required output power, range of operation and end use (e.g. grid connection or battery charging).

The Vertical Turbine Harnesses the Turbulent Air Behind Vehicles

Those wind tunnel streets that cause pedestrians to curse could assume a major redeeming quality thanks to the Vertical Turbine project. Recognizing the fact that cities require enormous amounts of electricity but that wind farms are typically erected in rural locations, Dr. Gurmit Singh proposes an option perfectly suited to the metropolis.
