#1844: Flamenergy

Visiting Australia recently made me think a lot about the dangers of bushfires.

Today’s invention is an attempt to help.

When a fire approaches one of a number of outstations, the temperature difference between the firefront and underground can be used to power eg a Stirling engine.

This could then be used to automatically pump water onto the roof of a building under threat, damping down any windblown sparks and smouldering embers.
