About Us

RTSL was established by its founder and serial inventor, Andrew H Mackay, to provide space heating and hot water for all by exploiting the 'cold renewables' such as wind, waves, tides and river flows in innovative ways using wind, wave, tidal and river thermines.

RTSL will shortly be pitching for investment to build a wind thermine factory to prepare for the inevitable hoarding of fossil fuels by exporting countries as early as 2035. Burning imported biomass to heat buildings is unsustainable to our island nation because by 2035 ships will have to dock every 12 minutes to keep our homes, hospitals and other commercial buildings heated throughout the year.
