This invention relates to a variable pitch hub for propeller-blades in order to maximize efficiency and output in terms of rotational speed and torque to a wind power driven generator, maximize strong wind survivability for propeller, generator and support-tower, as well as a speed regulating gear.
This is a self energizing Heating & Cooling furnace and air conditioner. Concept of this is to use 1/3 less electricity than your ordinary furnace. All furnaces have a blower motor, a heating source and air conditioning source of either gas or electricity.
The SST is a simple, but highly accurate, tracking system to keep photovoltaic panels or other sun energy receivers oriented accurately to obtain highest possible receiver efficiency.
Description:
The SST simply consists of small photovoltaic panels, a shadow board, and small double pole-single throw relays to drive the receiver’s aiming motors.
This idea provides two benefits simultaneously - it produces free electricity and reduces flooding and erosion.
The idea is to put large rain-storage tanks on the roofs of skyscrapers. Then hours or days after a rain storm, the water would flow to ground level through a pipe with a water turbine to generate electricity.
In Developing countries, the Power plays a crucial role in development. In the Electrical Distribution Systems, Power Billing is crucial as it involves collecting Revenue for the Government. But due to Power Corruption, the quality of Power is being reduced and thereby affecting the different electrical equipment connected to it.
This idea combines 3 forms of energy usage into 1 yielding a reduction in electric and gas consumption. Heated water is used by every household and, in many parts of the world, AC (air conditioning) is used for several months of the year.
Many older buildings including homes are constructed or painted with dark, heat collecting materials that increase the cooling costs in the summer months and do little to heat the home or building in the winter months.
The system use the refrigeration cycle principle working in reverse by the refrigerant absolving heat from sun panels and the refrigerant cooling from earth buried heat exchanger (liquidification). Under the refrigeration cycle principals the temperature difference is converted in pressure difference,
I haven't driven a car since November of 2009 and I use my bicycle as my primary mode of transportation. During these past months I realized that my iPhone would run out of power while riding my bike using GPS navigation and stopping to take pictures, surf the web, play games, call, watch videos and listen to music.
This entry seeks to draw attention to the looming crisis plug-in automobiles will have on our outdated, inadequate electrical grid infrastructure. For any benefit to be gained from plug-in automobiles, adoption rates will have to be substantial enough to cause severe stress to our already overtaxed electrical grid.
