The universal rationale for the massive public commitment to wind power is that it is environmentally benign. But land based wind power has at least two major environmental problems—noise and the killing of bird populations that has begun to cause serious concern among mainstream environmentalists. As an alternative we propose an airborne wind turbine. The turbine will be launched in tow behind a moving vehicle on land or a vessel at sea. In the space of less than 100 meters it will be airborne and achieve working altitude (550-850 meters) within 5 minutes after the launch. It will stay aloft indefinitely once anchored to the ground or sea bottom, and will provide power at 100% of its rated capacity ...

AHGS is an idea to create a future system grid to substitute the actual distribution of gas for cars.
Hydrogen is one of the interesting future fuels besides charging batteries. So hydrogen is used in fuel cell-powered cars. To generate hydrogen autonomic AHGS is an approach. The system collects filtrated water from the rain and electric power from the wind. With this inputs hydrogen can be generated in the water electrolyses. If the system is in regions without enough rain, it could also be used water from other sources. With the water from the rain and the power of the wind the suggestion don't need any further inputs or equipment like offshore exploration drillings, tankers and so on. ...

This is a new concept in renewable energy production, called AirWatt. It can produce much more electrical power per unit area of land than solar, wind, or hydro power plants. Whereas solar works only during sunlight hours, the AirWatt power plant can usually run 24 hours per day in appropriate locations. AirWatt plants use atmospheric air as the heat source and evaporating water as the heat sink. The warm air is used to boil a refrigerant, which turns a turbine, and the water evaporation condenses the refrigerant.
Our computer simulations of the thermodynamics and aerodynamics have already demonstrated that AirWatt functions well.
The average amount of water flowing through the turbines at Hoover Dam is about ...

Alair aluminum-air battery for sustainable electricity production

This device is intended as a standalone electricity generator for off-grid living, in either developed or developing countries. It uses the chemical reaction:

4Al + 3O2 + 6H2O ? 4Al(OH)3

to produce 12 VDC electricity which is then inverted to produce either 120 VAC or 240 VAC output. The device is simple to manufacture and uses easily-obtainable materials. Salt water is used as an electrolyte, aluminum plates for anodes, and activated charcoal as the air electrode. A carbon waffle grid embedded in the charcoal serves to collect electrons. Sponge is used to contain the electrolyte. Since the saltwater reaction produces about 0.5 V, 24 cells are required.

One of the major problems ...

The MicroUtility will provide modern utility services to rural sub-Saharan Africa at a low capital and operating cost, using easily maintained, low-tech equipment. The services that the MicroUtility provides are: (1) wastewater treatment; (2) potable water supplies; (3) high-protein animal feed; (4) fertilizer; and (5) gas service for lighting and cooking. The MicroUtility utilizes solar energy and biomass recycling as the sustainable inputs for the system. Wastewater treatment is a key function of the MicroUtility. Animal waste, food waste and human waste are collected and mixed together to form a slurry. The slurry is delivered to one or more anaerobic digesters. The anaerobic digesters are made of low-cost components. The main tanks are rugged plastic. A solar oil heater ...

Storage of electrical energy is a growing problem.

This concept is based on the well-known pumped storage, which is a type of hydroelectric power generation. The method stores energy in the form of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost off-peak electric is used to run the system pumps. During periods of high electrical demand, the stored water is released through turbines. The efficiency off a pumped storage system is typically 75 to 80 %.

Countries like Denmark have only few hilly areas, with are suitable or available for pumped storage systems.

This new form of pumped storage system is based on an underground storage reservoir, where the water is enclosed in a bladder ...

Ships have propellers which are designed to fling water relatively rearwards in an efficient manner. Tidal power is one area of ‘alternative energy’ which seems as if it has some chance for being cost effective.

My invention is therefore to combine this information and create a simple source of renewable energy.

Take ships which, due to economic conditions, are not currently being used and moor them securely in regions of high tidal flow activity.

Equip each with a generator, if they haven’t already got one on board. Disconnect the propeller shaft from the engine (using whatever clutch system is already being used). Then, allow the tidal movements to drive the props with the hull anchored in position (they might ...

Spills of oil from drilling and transportation operations will continue to cause environmental degradation and economic losses.

Millions of tons (annually) of sustainable (U.S.A-available) resources can help reduce the impact of the environmental insult of uncontained oil. Poultry feathers are being incinerated or disposed into landfills instead of being used as a renewable resource. Feathers have been used in various applications, such as insulation or circuit boards.

Feathers, alone, can help contain oil spills by limiting the spread of the oil in water. The adsorbent quality of chicken feathers, and other poultry feathers, can contain oil, just as living birds collect oil and must be cleaned.

When poultry-feather pieces are coated with oil-eating bacteria, augmented with nutrients, that can ...

The US Interstate Highway System consists of about 47,000 miles of highway. Dividing the highway is a median strip that average about 40 feet in width. Thus, Interstate Highway median strips constitute about 9.93 billion square feet, 228,000 acres of land.

If this land were used to grow biomass whose primary function was to act as a carbon sink, and assuming an average optimized biomass production rate of 7 dry tons per acre per year, then approximately 1.6 million dry tons of biomass could be grown each year in the highway median strips. Assuming that a dry ton of biomass is minimally about 40% carbon, this would provide a carbon sink for 638,000 tons of carbon each year. Since ...
