Human Energy Harvesting to Power Portable Devices

Micro-Energy Harvesting is possible through two identified sources of energy: 1) the energy provided by a living being like an animal or a human; 2) the energy supplied by the environment. Human Energy Harvesting technologies enable the power independance of portable handheld electronic gadgets, and thus reduce the dependancy of the battery and mains power. […]

Solar Power Generation possible during night time? Yes. As you know the output of a solar power plant depends on the time of day and cloud cover. To generate power from the solar power plant, you need to store the solar energy. Different ideas have been cooked up by researchers for storing the power created by solar power plants – batteries, ultracapacitors, fuel cells, hydrogen generation, flywheels – but all of these are far from being affordable enough for large scale power needs. The better alternative is to store power as heat before it’s converted to thermal energy.

Thermoelectric (TE) energy harvesting is based on the heat flux through a thermoelectric element or a thermogenerator comprising a multitude of such elements. The heat flux is driven by a temperature difference across the element. The generated voltage is proportional to the number of elements and the temperature difference. Thermoelectric thin-film micro devices with high […]

Developers have been investigating light-harvesting thin film solar panels made from nanotechnology, and promoting solar power efficiency metrics to make the technology marketable. New theoretical approach with computer simulations shows that current predictions to increase efficiencies won’t work. The increase in efficiencies cannot be achieved yet through Multiexciton Generation, a process by which several charge carriers (electrons and holes) are generated from one photon.
