Figure 1. Self Sufficient Home with Combined Heat and Power Combined Heat and Power (CHP) Engineers combined heat and power (CHP) systems, also known as cogeneration, generate electricity and useful thermal energy in a single, integrated system. CHP is not a technology, but an approach to applying technologies. Heat that is normally wasted in conventional power generation is recovered as useful energy, which avoids the losses that would otherwise be incurred from separate generation of heat and power. While the conventional method of producing usable heat and power separately has a typical combined efficiency of 45 percent, CHP systems can operate at levels as high as 80 percent. Some micro-CHP technologies use mechanical engines, such as internal combustion [...]

Material Engineers : Pros and Cons of Solar Powered Cars

2018-07-25T09:17:33+00:00

Figure 1.  Solar Powered Cars in the Future Although a solar power car may not be commercially viable right now, there are ways that solar power can be added to existing designs to make vehicles more efficient. Material Scientist examine the pros and cons of this technology, it can continue to move forward in development to help save on fossil fuels, and the electric grid and pollutions. Solar-powered vehicles (Solar Cells ) have zero emission level, as they don’t utilize non-renewable resources and burn fuel. The electric motors generate electricity (See Figure 1.) that doesn't emit any greenhouse gases or any other pollutants. These cars are quieter than the vehicles powered by conventional fuels, which don't cause noise pollution as well. Lets [...]
