most energy comes from the sun. an extremely small amount of this solar energy is absorbed by photovoltaics (pv) and converted to elecrticity. most of the time solar energy is
- absorbed by the earth, typically resulting in temperature rises. temperature differentials follow, creating winds, which blow over the ocean creating ocean waves
- or its absorbed by water, evaporating, precipitating, and causing rivers to flow
- or its absorbed by a living plant, getting stored in cells as chemical bonds with various properties, used for food or fiber, as well as fuel.
these forms of energy can be utilized. for hydroelectric and wind, efficiency usually increases with larger scale. for small scale implementations, technology should be chosen that doesn't need to be large to be efficient.
biomass gasification tech -
NOT logging big trees, using fallen branches, overcrowded understory, and powerline maintenance. waste, burnt in piles, called slash
gasification is fascinating in that it very quickly reveals itself to be the operating system of the fire, it is a low level series of mechanisms and processes that combine together usually invisibly within a combustion environment that result in the thing that we call fire
