The UK is suffering from some pretty horrendous weather. Lots of snow in a country that is normally pretty temperate and bear in mind that people here lose the ability to drive if there is more than an inch of snow on the ground.
This coming weekend I shall be driving half way up the country to spend a long weekend in a field with 2000 other people who are just as stupid as me. (I shall also be testing out my Frontier Stove
So I've decided that if I am indeed going to be sleeping under canvas, I'm going to be snug and warm doing so... And without either suffocating from carbon monoxide or turning my tent into a toasty conflagration.
The solution I've come up with (aside from ludicrous amounts of bedding on my camp bed) is to make a storage heater.
The principle is simple enough. An object with a high thermal energy storage capacity is heated up... then when the heat source is removed it stays hot and radiating heat for quite some time.
Modern storage heaters tend to use ceramics... but in this project I shall be using house bricks and sand (to fill the gaps)
IMPORTANT SAFETY NOTE AND DISCLAIMER
This Instructable involves very very hot items (such as fire, heated steel and brick). Do not place the storage heater anywhere it could do damage to people or property. I am not responsible for anyone being a muppet.
