Frontotemporal dementia (FTD) or frontotemporal degenerations refers to a group of disorders caused by progressive nerve cell loss in the brain's frontal lobes (the areas behind your forehead) or its temporal lobes (the regions behind your ears).
Solar thermal (heat) energy is a carbon-free, renewable alternative to the power we generate with fossil fuels like coal and gas. This isn't a thing of the future, either.
Solar energy is energy which is created from sunlight, or heat from the sun. Solar power is captured when energy from the sun is converted into electricity or used to heat air, water, or other fluids.There are currently two main types of solar energy technologies:1  solar thermal: these systems convert sunlight into thermal energy (heat). 2  Most solar thermal systems use solar energy for space heating or to heat water (such as in a solar hot water system). Most solar thermal systems use solar energy for space heating or to heat water (such as in a solar hot water system). 2  However this heat energy can be used to drive a refrigeration cycle to provide for solar based cooling.
