...by switching on the air con every time the thermometer went past 70...for example. But I do think @Kemosloby makes a point - there are very often unsophisticated and non-technological solutions that are far easier for each of us to implement but we look right past them in our earnest desire to find a clever fix. The fan argument in this thread is a perfect example...it seems like most 'sophisticated' people don't know that cooling is best achieved by an appropriate combination of air circulation and evaporation - and yet people had hand fans 5000 years ago and indigenous people in hot climates built houses with high roofs and natural materials that achieved cooling quite efficiently long before the modern technological equivalent was packaged into a convenient remote-controlled device. Mind you, termites have been doing it for millions of years.
