Reading Chippyteas's message about the cost of electricity got me thinking, has anyone here heard of rocket stoves, theres load to see on youtube and they really work. I had mine on today and boiled 2ltrs of water in less than 15 minutes using a small amount scrap wood, my interest came about because i like my cups of tea but using a 3kw kettle just didnt sit right, i also use it when wine making to boil the sugar syrup etc. There is one other trick but i havent tried it yet which is auto syphon which might be usefull for beer brewers. I have 2 vacuum flasks which are topped up and next mornings brew just takes a tickle in the dreaded electric monster, cheers Dave ps no good with links so no links !!
