Macrowave Control

A concept of a Macrowave Controller

The whole integration of this composes with the followings: 20 to 30 self-constructed civilian-crawler-type-heavy-autonomous-vehicle (CCTHAV), each weighted about 3 to 5 tons with elevating-poles to assemble the huge platform in figure. This reconfigurable platform has a cone or cornucopia shape metal structure,

Making Fuel from Greenhouse Gases

A thermal plasma technology capable of instantaneously dissociating large carbon containing molecules directly into a mixture of ionized particles can generate energy from gases attributed to the greenhouse effect.

About 95% of the hydrogen produced today from natural gas using steam-methane reforming,

Marstian Wind Turbines for Clean Future

The futuristic technology for the colonies on Mars.

---------------------------------------------------------

The Planet Mars has been an issue of scientific curiosity for centuries, not least because Mars is the only terrestrial planet whose surface can be directly observed in detail from the Earth. Although Mars is smaller at 11% of Earth's mass and 50% farther from the Sun than the Earth,

Microbial Fuel Cells (MFCs) for Recovery of Energy and Nutrients from Pig Waste

Technologies based on microbially-catalyzed reactions are cost-effective for managing waste at a large scale. 125 million dry tons of pig waste is produced globally every year. Pig waste has high concentrations of organic carbon and nutrients like nitrogen that, when discharged to the environment, can lead to surface water eutrophication,

Midnight Sun

Who says the sun can't shine at midnight? What if solar panels charged up a battery during the day, which then went on to power a street light at night?

The EIA reports that up to 12% of all electricity goes into lighting. Needless to say, it's a big part of our energy footprint.

Modifying Highways to Improve Fuel Efficiency

At highway speeds, a large amount of energy is used to overcome aerodynamic drag. I believe we can make changes to our highways that can reduce that drag.

Currently one way to reduce drag is to drive slower. The force of aerodynamic drag goes up with the square of the vehicle’s speed, so driving slower reduces the drag.

Molten Salt Solar Agri-Crop Dryer

Due to lack of cold storage facilities and packed food processing facilities in developing countries most of the vegetables and other crops get rotten within week of harvest. By drying the vegetables and crops they can be preserved for longer periods and the supply of vegetables and crops can be extended up to six month or longer.
