This Engine Generates Electricity Using Waste Hot Water

A new engine converts waste hot water from industrial equipment into electricity.

NATURE WORLD NEWS - Exergyn, a startup based in Dublin, Ireland, is planning to run the first industrial trials of the new energy-efficient engine by next year, New Scientist reports. The engine generates electricity from heated water that is left over from other equipment. According to co-founder and chief executive Alan Healy, waste hot water (low-grade waste heat or LGWH) from industrial processes amounts to about twice the energy in Saudi Arabia's oil and gas output per year.

The power of heat - Decentralized Energy

'The whole idea of renewables versus non renewables has become a focus - the thing for me that Europe has got to do is be very strongly focused in delivering an energy system for all of our energy users in a way that is affordable. 

'Fifty per cent of the energy lost in our system is heat from thermo-generation - we are throwing away as much heat as we are using. It's bad for the economy and climate.'

Each arched Watly unit is fitted with photovoltaic solar panels that generate heat and solar power. Water is pumped into the tank and made drinkable through a process called vapor compression distillation, which uses solar thermal energy to vaporize water and separate it from contaminants ranging from sea salt to poisons.
