can we generate our waste energy?

Answer 1

Waste heat recovery, also known as Recycled Energy, methods used with industrial process heating operations intercept the waste gases before they leave the process, extract some of the heat they contain, and recycle that heat back to the process.

Various Methods for Recovery of Waste Heat

Low-Temperature Waste Heat Recovery Methods – A large amount of energy in the form of medium- to low-temperature gases or low-temperature liquids (less than about 250 degrees F) is released from process heating equipment, and much of this energy is wasted.

Conversion of Low Temperature Exhaust Waste Heat – making efficient use of the low temperature waste heat generated by prime movers such as micro-turbines, IC engines, fuel cells and other electricity producing technologies. The energy content of the waste heat must be high enough to be able to operate equipment found in cogeneration and trigeneration power and energy systems such as absorption chillers, refrigeration applications, heat amplifiers, dehumidifiers, heat pumps for hot water, turbine inlet air cooling and other similar devices.

Conversion of Low Temperature Waste Heat into Power –The steam-Rankine cycle is the principle method used for producing electric power from high temperature fluid streams. For the conversion of low temperature heat into power, the steam-Rankine cycle may be a possibility, along with other known power cycles, such as the organic-Rankine cycle.

Small to Medium Air-Cooled Commercial Chillers – All existing commercial chillers, whether using waste heat, steam or natural gas, are water-cooled (i.e., they must be connected to cooling towers which evaporate water into the atmosphere to aid in cooling). This requirement generally limits the market to large commercial-sized units (150 tons or larger), because of the maintenance requirements for the cooling towers. Additionally, such units consume water for cooling, limiting their application in arid regions of the U.S. No suitable small-to-medium size (15 tons to 200 tons) air-cooled absorption chillers are commercially available for these U.S. climates. A small number of prototype air-cooled absorption chillers have been developed in Japan, but they use “hardware” technology that is not suited to the hotter temperatures experienced in most locations in the United States. Although developed to work with natural gas firing, these prototype air-cooled absorption chillers would also be suited to use waste heat as the fuel

Answer 2

some wasted energy can be reused

for instance a car that stops , thje kinetic energy can be stored in a rotating massive wheel , the difficulkty with this is the gyroscopic effects

You can put mirrors in your house so that electromagnetic energy is reflected back into the hous instead of the space where no-one needs it.

when boiling water it is better to do that in a magnetron than on a fire outside in the garden

do not take a car just walk , the enry of walking can also be stored in batteries, by wwearing magnetic shoes and coil stockings where the electricity is genearated as wyou walk. The enegry you can use to warm you , or to power you mobile telephone to tell your boss you will be late again

Answer 3

Bio gas can be produced with degradable bio waste.

Answer 4

yes wastes can be recycled and while recycling heat is produced which can be converted to electricity by various processes

Answer 5

no
