The Future is Green
A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.
What is DiGeSPo?
DIstributed CHP GEneration from small size concentrated Solar Power (DiGeSPo) 
The DiGeSPo project aims to research and build a modular 1-3 kWe, 3-9 kWth micro Combined Heat and Power (m-CHP) system based on innovative Concentrated Solar Power (CSP) and Stirling engine technology. This CSP m-CHP unit will provide electrical power, heating and cooling for single and multiple domestic dwellings and other small commercial, industrial and public buildings. It integrates small scale concentrator optics with moving and tracking components, solar absorbers in the form of evacuated tube collectors, a heat transfer fluid, a Stirling engine with generator, and heating and/or cooling systems.  
The solar power plant is based on a series of small 40 cm parabolic dishes that concentrate solar radiation onto an evacuated tube through which thermal fluid flows, and is heated to temperatures of 250-350°C. This enables a stirling engine to simultaneously co-generate heat and electricity by recovering the engine’s heat. Our target is to achieve 60-70% global efficiency compared to incident solar radiation.  
DiGeSPo intends to incorporate this small thermodynamic solar powered and hybrid system into residential buildings, in an architecturally acceptable manner and with low visual impact, that will generate heat and electricity. The project covers the whole of the R&D chain from initial concept to development, modelling including simulation of each sub-module; production and testing of prototypes, production and field trials of full system prototypes.  
Distributed m-CHP Generation from small-scale Concentrated Solar Power
  1. New glass technology enable parabolic trough solar concentrators for small scale systems;
  2. New ceramic-metal coatings can provide improved optical behaviour and material durability for evacuated tube collectors;
  3. Modified stirling cycles and new compact heat exchanger technology can improve the performance of small heat engines;
  4. There is an urgent need for alternative m-CHP systems.
