PV convert light into electric current using the photoelectric effect. Applications
Kaloyeros, Ph.D., vice president of CNSE. "In healthcare, for example, nanotech will be used to develop biochips for blood testing and DNA sequencing, smart chips for spinal cord injury and other physical challenges, chip-controlled patches for drug delivery and monitoring of bodily functions, and non-intrusive sensors for detection of disease, such as cancer cells." Other key sectors that will benefit are alternative renewable energy (environmentally friendly biofuels), solar cells and photovoltaics, and national defense. "The power of nanotechnology is rooted in its ability to impact multiple industries," says Kaloyeros. "Nanotechnology is quite simply the most critical and enabling science and engineering discipline of the 21st century. As such, it will drive technological innovation and economic prosperity far into the future."
average rate of 20¢/kWh . The program is designed to help promote the government's green agenda and lower the strain often placed on the energy grid at peak hours. With the incentives offered by the program the average payback period for a residential solar installation (sized between 1.3 kW and 5 kW) is estimated at 18 to 23 years, considering such cost factors as parts, installation and maintenance, as well as the average energy production of a system on an annual basis. Photovoltaics are 85 times as efficient as growing corn for ethanol. On a 300 feet (91 m) by 300 feet (1 hectare) plot of land enough ethanol can be produced to drive a car 30,000 miles (48,000 km) per year or 2,500,000 miles (4,020,000 km) by covering the same land with photo cells. The deserts of the South Western United States could produce sufficient electricity to fulfill all of the electrical needs of the United States, and could use electrolysis to produce Hydrogen from water to power aircraft
