OK, most forums like new members to post a bit of an intro.
Not sure if that is a req here, but here we go anyway.
I'm in Poole, Dorset.
I looked into bio long long ago, as an aside, whilst I was researching LPG sytems. Ran LPG for about 15yrs, but now I'm on diesel, it's time to revisit bio.
I have a central heating cylinder coming at some stage, possible to make a small reactor from. But this weekend I'm going to make up a conical bottom vessel from a 205ltr barrel.
I am still collecting the bits together, and have yet to start polling around for oil supplies. So it may take a little while before I make my first brew.
