Inventors on hunt for way to make clean water on moon

UK Space Agency awards 30k in funding to 10 teams racing to solve the complex problem

Inventors hope to crack how to create a reliable clean water supply on the moon - and it may involve a microwave oven from Tesco.

The goal to set up a crewed lunar base was launched many moons ago but has yet to come to fruition. With reliance on water supplies from Earth risky and expensive, one of the many challenges is how to extract and purify water from ice lying in craters at the lunar south pole.
