Thursday 4th December

Inspired by his visit to Energy Cafe last week, Andrew returned today with his fantastic invention: a Swirl Stove.

Made from a customised flue, the stove ignites with a micro amount of electricity from a battery.

Andrew added sawdust pellets and a drop of parafin to get it going.

The flame spins in a smokeless swirl…

How long will it take to boil water in the storm kettle?

Just three minutes and one handful of pellets!

The wood chippings that Andrew donated burn just as well. A great advantage of this stove is that: “it could continuously produce char from dried tree surgery waste…and still do your cooking.” It did a great fried egg!

You will need: willow branches and a tin can with lid.

Chop willow branches into even lengths…

Fill the can with lengths of a similar width and close the lid.
