Still my favourite non-electronic gadget: a Stirling engine for your coffee/tea/hot chocolate

Welcome to my toy Stirling engine. It gets a good turn of speed with just a small nudge to overcome initial friction.

Turn up the volume to hear just how fast it is turning by the end:

The name Stirling engine comes from Rev. Robert Stirling, a Scotsman who patented the device, called the Heat Economiser, in 1816. Hopes that it would become a rival to, or even replacement for, the steam engine were never met as Stirling engines required temperatures that the materials of the day could not cope well with.

  1. the answer to all our energy self-sufficiency woes – the power of tea! Only thing is, will it generate enough to boil a kettle?

  2. The red kettle ? Why do you not approve of it ? I purchased it for Mark when first he moved into the flat that has been his home ever since, secure in the knowledge that red is better than blue, if push comes to shove. There were no yellow kettles available at the time.
