The process in which a solid fuel is converted into a gas; also known as pyrolitic distillation or pyrolysis. Production of a clean fuel gas makes a wide variety of power options available.

These brines are hot (300 F to 400 F) (149 C to 204 C) pressurized waters that contain dissolved methane and lie at depths of 10,000 ft (3048 m) to more than 20,000 ft (6096 m) below the earth's surface. The best known geopressured reservoirs lie along th ...

The natural, convective movement of air or water due to differences in temperature. In solar passive design a thermosyphon collector can be constructed and attached to a house to deliver heat to the home by the continuous pattern of the convective loop (o ...

The cutting of a grid pattern of grooves in a semiconductor material, generally for the purpose of making interconnections.

A measure of air purity that is equal to one complete air change (in an interior space).

see Peak Power

Air brought into a building from outside to replace exhaust air.

An air heater in which air is blown over electric resistance heating coils.

A curve that indicates the number of hours per year that specific wind speeds occur.

Waste material from households and businesses in a community that is not regulated as hazardous.

Solid fuels made from primarily wood sawdust that is compacted under high pressure to form small (about the size of rabbit feed) pellets for use in a pellet stove.

The maximum load that a device is capable of carrying.

A heat storage system that uses a heat storage medium, and where the additional or removal of heat results in a change in temperature.

A thin sheet of material (metal) of a heat exchanger that conducts heat to a fluid.

Any gaseous, liquid, or solid fuel used for indoor space heating.

The effect of cooling by the radiation of heat from a building to the night sky.

A unit of electrical capacitance; the capacitance of a capacitor between the plates of which there appears a difference of 1 Volt when it is charged by one coulomb of electricity.

An incorporated right, liberty, privilege, or use of another entity's property, distinct from ownership, without profit or compensation; a right-of-way.

A device for converting mechanical energy to electrical energy.

A unit of measurement for the ability of a material to retard the diffusion of water vapor at 73.4 F (23 C). A perm, short for permeance, is the number of grains of water vapor that pass through a square foot of material per hour at a differential vapor p ...
