Bladeless Wind Turbine

Every year windmills kill 573,000 birds in the US according to the Associated Press. By some estimates the total number of birds and bats killed worldwide every year runs into several millions.

In many areas of the world, the lack of readily available electrical energy, clean water, and employment opportunities are an interlocking problem that causes social strife, political conflicts, and limits the potential of millions of people. In a vicious circle,

A Compressed-air engine is a pneumatic actuator that creates useful work by expanding compressed air. A compressed-air vehicle is powered by an air engine, using compressed air, which is stored in a tank.

Conversion of 950va Tiger petrol generator to a renewable energy-RE powered 950va rotary genset is an experimental setup aim at carryout feasibility studies on ways of providing an alternating current- ac electricity generation for about 20hours /day. The 950va RE rotary genset is a combination of motor/generator arrangement.

Better side of the transmission of electricity through the HV DC are already proven! Application of DC / DC converters on the existing power grid, enabling translation T & D AC grid - into DC High Voltage Transmision & Distribution grid.

Application of DC / DC converters - transformers,

As far as this writer is aware, Cruise ship wastes are kept on board or possibly discharged far out at sea for no cost. To keep costs down for operators, certain marinas or nations could offer a barge based or mangrove/marina based bio-processing garden or off pump station.

Runoff from farms dumps fertilizer nutrients into the world’s oceans. This causes dead zones which are oxygen-starved where few or no fish can live. The Baltic Sea currently has a project to oxygenate dead areas using windmill and air pump technology (See

The aim of the project was to develop a hydro power plant for sustainable development. After going through the past and current prevailing scenarios, it was inferred that there were no sources of clean energy in the urban metropolitan today and one was desperately required.

From the viewpoint of the power to engine weight ratio, 2-stroke engines have at least 40% better performance than 4-stroke engines but they produce undesirable emission levels with poor lubricating management. Therefore, it will be the main challenge in the double acting ICE`s.


Modern world is witnessing the difficulty of managing the e-waste coming out of many sources, majorly from IT & BT companies, educational institutions in the form of unused PC’s and other things.
