OK illusion blown it wasn't Scott tents and man food boxes!
The grey water filtration plant developed by ESA (European Space Agency) for the
mission to Mars at present
this prototype is been tested at Concordia. They are to
receive the black water (urine etc.) filtration plant equivalent
next year. As well as a neat water purification system they
had a neat system of recovering the heat from the
generators and exhaust gases and producing hot water (during the summer
the boiler was not needed and even during
the winter only ran 25% of the time)
