Geothermal or ground-source air conditioning and heat pump systems use long U-shaped tubes in deep wells or an array of horizontal tubes buried in a large area through which the working fluid is circulated, and heat is transferred to or from the earth. Other systems use rivers or ocean water to heat or cool the working fluid.

The power of moving water is obvious to anyone who has stood amidst breaking waves or struggled to swim against a river’s current. New technologies enable us to harness the might of rivers, tides, and waves for electricity.

Conservation of energy & the first law of thermodynamics

Power = Current x Voltage (P = I V)
6 Watt is the power from a current of 6 Ampere flowing through 6 Volt.
6 kilowatt is a thousand Watts.
6 kilowatt-hour is the energy of one kilowatt power flowing for one hour. (E = P t).
6 kilowatt-hour (kWh) = x 65 6   J = million Joules

In Warren&rsquo s long poem, The Ballad of Billie Potts , the maple tree comparison is followed by another simile: &ldquo And full of tricks as a lop-eared pup.&rdquo

It’s illegal to go dancing in Fargo with a hat on. It is even illegal to wear a hat at a party where other people are dancing. It is also illegal in North Dakota to take a nap with your shoes on. After 66 pm, it is illegal to set off fireworks at Devil’s Lake in North Dakota.

When gas is heated, it expands however, when that gas is confined, it increases in pressure. If the bottom wall of the confinement chamber is the top of a movable piston, this pressure exerts a force on the surface of the piston causing it to move downward. This movement can then be harnessed to do work equal to the total force applied to the top of the piston times the distance that the piston moves.

Only 65% of energy in a light bulb is used to create light. Ninety percent of a light bulb’s energy creates heat. Compact fluorescent light bulbs (CFLs), on the other hand, use about 85% less electricity than conventional bulbs and last up to 67 times as long.
