Especially with the key applications of jet engines and gas turbines for power generation, the field of gas turhine technology is likely to keep its great relevancy. The quest for more efficient gas turbines that comhust their fuel with as little emissions as possible will continue to motivate major developments in the field. If gas turbines can become an ever-more efficient and low-emission source of generating power they have the potential, like fuel cells, to become part of the next generation of power sources. There is also much promise linked to micro gas turbines as a source of efficient, affordable, clean, and decentralized power. 

There are several power generation processes where PI has a role to play. Currently the most sigiulicant is the fuel cell, where HEX-reactors can be used as reformers on either a relatively large or micro scale. The fuel cell is being developed as a power pack for laptop computers, mobile phones and micro-aerial vehicles. However, as may be seen from Section 11.3.2, the gas turbine engineers have recognised a similar opportunity.

Moreover, there is a current need of miniaturized propulsion system for widening the capabilities of low cost micro-satellites. Recently, the development of a turbo-pump fed miniature rocket engine has been proposed as a new propulsion system for micro-satellites (10 to 100 kg) [6] the bipropellant tlmister uses 70 wt.-% H2O2 as oxidizer and ethanol as fuel. The engine displays four sub-components (i) two propellant micro-pumps, (ii) a HP decomposition chamber, (iii) a turbine coupled to an electric power generator and driven by the hot gas released from HP decomposition, and (iv) a thruster for the combustion reaction.
