Less than 3% of the input energy is converted into usable light.

You are trading time for mechanically input energy and chemicals.

Generally at all performances a part of the input energy will be dissipated as heat.

Concentration of the input energy accordingly is one option for efficiency and economy.

Prior to fusion ignition, the reaction needs constant input energy to continue.

The conversion of input energy to heat is not always undesirable, however, as there are some practical applications.

A well-designed motor can convert over 90% of its input energy into useful power for decades.

Each class may or may not be homogenized, depending on the amount of input energy.

About 60% of input energy ends up as useful kinetic energy.

Whether the natural source is air, moving water, coal or petroleum, the input energy is a fluid.

Input energy is the energy stored in the fuel.

Thus the input energy is shed as mostly heat (infrared) but also as visible light.

The energy distribution below is represented as a percent of total input energy:

Direct transformation of energetic particles to electricity or other input energies."

Since all the input energy for such processes is heat, they can be more efficient than high-temperature electrolysis.

These sensory organs transform the input energy into neural activity-a process called transduction.

The input energy propels the work and is mostly converted to heat or follows the product in the process as output energy.

Slope efficiency can similarly be defined in terms of output and input energies instead of powers.

Active stability systems are defined by the need to input energy to the system in the form of a pump, hydraulic piston, or electric actuator.

However, production of hydrogen from water requires large amounts of input energy, making it incompatible with existing energy generation.

Recovering some of the heat that would otherwise be wasted - typically equal to one-third of the input energy - impoves efficiency.

Plant energy is produced by crops specifically grown for use as fuel that offer high biomass output per hectare with low input energy.

In energy, the break-even point is the point where usable energy gotten from a process exceeds the input energy.

However, realistically, geometries must accommodate the input energy (fuel injection or input light) used to heat the emitter.

Just as the nutritionists of Selene had learned, aquaculture produced more protein per unit of input energy than barnyard meat animals could.
