### power:

Solar power
* IS workable as are a number of other renewable energy sources.
* can enhance performance and reliability of general water boats
  - help California
  - now substitute for plutonium on space probes
* captures the heat and light of the sun to generate electricity.
* comes from solar panels that gather energy from the sun.
* costs half as much as lighting with kerosene.
* creates forward drive from an electric motor, which in turn creates 'relative wind'.
* diffused energy source - it is available only when the sun shines.
* drives an ultra-violet water purifier.
* has domestic, commercial and industrial usage
  - two big advantages over fossil fuels
* helps keep livestock out of riparian areas
  - to save energy in all seasons
* is alternative energy
  - clean power
  - complicated due to changes in seasons and from day to night
  - employed to supply lighting
  - nonpolluting
  - often less expensive than extending power lines
  - one of the simplest forms of renewable home power
  - pollution-free during use
  - produced silently with no pollution and no depletion of resources
* is the fastest-growing source of energy
  - technology of obtaining usable energy from the light of the sun
* is used in everyday life
  - to charge batteries so that solar powered devices can be used at night
* makes sunlight important.
* means exactly that, power or energy derived from the sun.
* operates all the electrical lights, fans and the water pump.
* provides light and operates a fan, and shower water is heated via individual heaters
  - at the flick of a switch
* relies on the energy produced by nuclear fusion in the Sun.
* remains one of the world's fastest growing energy sources.
+ Renewable resource, Types of renewable resources, Solar power: Energy :: Materials :: Economics
  * Solar power is the technology of obtaining usable energy from the light of the sun. Solar energy has come into use where other power supplies are absent, such as in places far off from the national electrical grid and in space.

Spiritual power
* comes from prayer and other renewing experiences.
* is based on love and truth
  - related to both mental and physical health
  - released through prayer

State power
* is economics as well.
* is, therefore, the principal dimension of political power.

Tidal power
* Most tidal power is generated by energy.
* can harness ocean movement resulting from gravitational forces of the moon.
* cheap source of energy.
* has no toxic waste.
  - used in a few locations world-wide
* operates by building a barrier across a river estuary.
* uses reversible turbines that both manipulate the flood and ebb tides.
* way to make electricity from currents.

Unpredictability
* intrudes at larger scales where most systems are fluid and chaotic.
* is power
  - quality
* is the beauty of science
  - nature of life in Afghanistan
  - uncertainty

Water power
* Most water power is used to generate electric power.
* is an old and safe source of energy.
* meets about two thirds of the nation's electrical needs.
* predates the use of electricity.
* uses no fuel in the generation of electricity and so has very low operating costs.

Wattage
* determines how much light is produced, with higher wattage bulbs producing more total light.
* has nothing to do with the amount of light produced by a lamp.
* is also a measurement of heat
  - determined by multiplying voltage by circuit amperage
  - the measure of electricity consumed
* practical way of measuring light.
* refers to the average power load.
