Lontra Blade compressor (http://goo.gl/czsej) first uses: waste water aeration, oil free industrial air compressors and automotive superchargers.
PyroPure (http://goo.gl/VMBKN), Ethos Energy (http://goo.gl/5LPEF) also Mitie has published paper on potential (http://goo.gl/Ygm8w); for hazardous waste pay back can be only c. 2-3 years.
Oxford Photovoltaic's solar cell technology uses cheap, abundant, non-toxic & non-corrosive materials screen printed on glass. (http://goo.gl/kcJF4).
KiWiPower helps companies remove stress in National Grid by reducing electricity consumption when most polluting & expensive. National Grid pays for service as reduces peak demand (http://goo.gl/LDuUA)
Oxford PV and Lontra certainly looked quite unique; the former still working to finalise details; improve efficiencies (today 5% but aiming for 20%), scale up and guarantee a 25 year life span or something equivalent to the glazing facade in which they will be placed etc. Very exciting though the range of applications and colours etc..
