On a typical aircraft wing, a surface that rises from the top surface to help with laminar flow, and depending on the speed, it may eliminate or reduce the sonic boom by creating a secondary shock wave that would cancel out the primary shock wave before it reaches the ground. This would be on each wing top, and a computer would have to control this, so that the correction can keep up with changes in altitude and speed.
My thinking on this is that the secondary wave might be out of phase with the primary shock wave at altitude, and as the waves propagated towards Earth, they would intersect and cancel out. Kind of the same way an audio ...
In the classical movie/TV shot of an aircraft touching down, tires meet the payment with a load squeal and a puff of smoke as they spin-up. Annual commercial flights in the United States are approaching 10M (Research and Innovative Technology Administration (RITA) • U.S. Department of Transportation (US DOT) yielding more than 27,000 commercial landings per day in the United States alone. The proposed design reduces spin-up wear and the associated replacement frequency, resulting in a twofold cost savings. Reducing spin-up wear would allow a greater number of takeoff/landing cycles per tire, reducing material cost for the aircraft owner. Indirectly a reduced maintenance frequency can also allow greater coordination of scheduled “out of service” time for the aircraft operators....
Wind energy harvesting technology has established its market due to the excellent advantages it possesses. At the same time, severe limitations of this technology has emerged. This is a step forward from the combustion based energy generation techniques used before; in a way that the ill-effects of green house gases were realized much later in time. The intermittency of power generation is the largest pitfall of current wind energy source. Therefore, an integrated system that can harvest more than one energy source, while operational, is proposed.
Along with wind, rain and snow are also highly energetic resources, if harvested right. A long pendulum like structure will gather large swing distances during high winds. It will naturally continue swinging even ...
Energy conservation is a key issue faced by all the countries these days. It has been estimated that 20 to 50 % of the energy consumed is due to lighting. When vehicles stop for signals the kinetic energy gets wasted as heat. We can trap some part of this energy and utilize it for lighting streets as wells as signal lights. Piezo electric crystals convert mechanical energy to electrical energy. However the voltage generated using piezo electric crystals is proportional to the applied force which in turn is a function of time.
In this work we place the piezo electric crystals at the traffic line as shown in figure 1 marked by black boxes. Whenever a vehicle crosses the ...

The Trekr 3X-1© is a design for a revolutionary and radical electric 3-wheel vehicle (F-117 Stealth Fighter inspired) intended to be totally amphibious and to be piloted on either land or water utilizing the same controls. The facet body segments are composed of aluminum panels which are formed in the shape of cake-pans. These panels are joined in the assembly at their upturned edges, which face the outside, to form an external exoskeleton frame. Once panels are joined, the voids left are filled with formfitting urethane panels for aesthetics as well as to provide additional buoyancy and aero/fluid-dynamic efficiencies. The panels that make up the roof and the hood are also covered with photovoltaic cells to provide additional charge ...
Of a city’s total electricity consumption, more than 25% of the power is just consumed by the very basic need for air conditioning – to keep the temperature inside offices, homes, malls, shopping complexes, hypermarkets, cinema halls, factory complexes – at an ambient temperature for comfortable working, living and leisure.
MY INVENTION makes it possible to generate a self-perpetuating source of electrical power from an everyday appliance – the AIR CONDITIONER – a power-guzzler found in almost every household and every office and factory, in 80% of the parts of the world – and turn it into a POWER GENERATOR.
An air conditioner has 2 main components :
a) An electric fan motor revolving at a very high speed, ...
A Cellular telephone unit should be made that a common regular telephone can be plugged into it. This Cellular unit will have or be plugged into a normal AC power outlet, as it will have to provide common battery for the regular telephone. In this case the cell unit would be some distance from the user and thus would have much less of any possible radiation hazard. Also you would have the option of placing the cell unit near a window where they usually work better. Thus then this would allow for having the telephone any place where just a wire connection or a telephone outlet is located.
The cellular unit could also have adjustable volume and frequency compensations ...
The invention refers to an installation for the termo-formation of the multilayer polymer plaques made of composite polymers in view of the re-introduction in the economic circuit of the polymer waste. The technical problem which is resolved with the invention is the one with which through the realization a formatting installation of the multilayer plaques made from polymer waste, it is mixed, stratified, and then is thermo-formed through specific procedures, the plastic debris considered waste, in new products used in different areas.
With the utilization of the formatting installation of the multilayer plaques the following advantages are obtained:
- The superior employment of the polymeric waste;
- High and constant quality of the products;
- Important energy and prime material savings;
The SuperCritical Air Mobility Pack (SCAMP) provides breathing air and full body cooling for hazardous materials workers, firefighters, and industry. Breathing air is essential for workers under oxygen deficient conditions or where toxic gases are or may be present. In addition to providing the basic air supply, SCAMP solves the major, recognized problem of heat stress in workers in impermeable suits and/or hot environments. Working time in confined suits is at present normally limited by the heat stress produced in the worker that reduces productivity and dehydrates and debilitates the worker. Use of SCAMP will allow each worker two to six times the working time in the suit each day as is obtainable with a standard Self Contained Breathing ...
