Large modern power plants works with an efficiency of 55 percent. They consist of a gas (fuel/cool) turbine with an efficiency of 35 percent and from a steam turbine which use the very high heat which comes out from the gas turbine to produce more energy- about 20 percent more, enabling those power plants reach 55 percent efficiency. They are called "combined cycle" power plants.

While re- using the heat to the steam turbine is achieved with very little energy, it requires the building of huge, expensive construction for the steam turbine. This huge construction is suitable only for power plants producing 100 MW and more. Since current combined cycle power plants costs around 700 USD per 1 KW for large power plants, they are produced almost only per order with a time delivery of 3-5 years, and financial commitment many years ahead.

Furthermore, those power plants requires a big land area and infrastructure. This fact also causes the need to have a few central power plants and causes the need to have a long leading power supply lines which result in a lost of aprox. 5% from 55% (2.5% totally) of the electricity.

Relaying on central power plants creates a security risk during war or terrorist attacks and vulnerability (also in regular days) of the total electric system where collapse of one power plant can create electricity collapsing in an entire country or region- like in August 2003 in the East Cost of the US and Canada .

Agam Energy Systems Ltd (AGAM) who specialize in ‘energy wise’ technological solutions is developing a small- mid power plant with an efficiency of 55-60 % compared to 38% of the best that are in the market in the same size. Those small dimension power plants will be for a 100KW- 40MW .

Those power plants can be part of the total electricity system or for local use, especially in rural areas, saving the need for long power supply lines and loss because of the leading lines. The price of the unit will be, per KW, half even compare with combined cycle units.

Since those power plants are small in size, they can also function as "on demand" power plants.

Agam's power plants can be more efficient per KW than combined cycle power plants because:

a) We build an high efficiency quasi isothermal compressor, where the compressed air is being cooled to 80 C as compare with 480 C in a conventional adiabatic compressor. Less turbine shaft work is required to compress cold air and therefore more of the turbine work is available to run the generator.

b) The heat exhausted from our turbine can be used to heat the compressed cold air (80 C) before being introduced to the combustion chamber. Thus it re-uses the heat from the turbine inside our engine, saving the need to re-use it only with huge steam turbine.

c) The liquid in the liquid ring turbine will be kept at 400 C and thus protect the turbine from being overheated even when the combustion temperature is high and there is no need to cool the turbine by bypass the combustion chamber.

The high temperature increases the efficiency farther more.
