I was perusing the HMRC rules (again, as you do) and noticed this in section 4.2.1:
https://www.gov.uk/government/publications/excise-notice-179e-biofuels-and-other-fuel-substitutes/excise-notice-179e-biofuels-and-other-fuel-substitutes
4.2.1 Exempt producers/users
If you have produced or used less than 2,500 litres of either:
any biofuel
any other fuel substitute or additive
within the last 12 months, and/or expect to produce or use less than 2,500 litres in the next 12 months, you are an exempt producer and do not need to register with us and account for duty. However, there are simple record keeping requirements, which are described in paragraph 4.9.1.
That bold bit I've highlighted above - it defines other fuel substitutes as:
Any liquid that is not hydrocarbon oil, biodiesel, bioblend, bioethanol or bioethanol blend but is used in place of mineral oil to fuel any engine, motor or other machinery is classed as a fuel substitute.
I wonder what that covers?

Probably alcohol fuels. I found this.
Methanol fuel has been proposed as a future biofuel, often as an alternative to the hydrogen economy. Methanol has a long history as a racing fuel. Early Grand Prix Racing used blended mixtures as well as pure methanol. The use of the fuel was primarily used in North America after the war. [clarification needed] However, methanol for racing purposes has largely been based on methanol produced from syngas derived from natural gas and therefore this methanol would not be considered a biofuel. Methanol is a possible biofuel, however when the syngas is derived from biomass. In theory, methanol can also be produced from carbon dioxide and hydrogen using nuclear power or any renewable energy source, although this is not likely to be economically viable on an industrial scale (see methanol economy). Compared to bioethanol, the primary advantage of methanol biofuel is its much greater well-to-wheel efficiency. This is particularly relevant in temperate climates where fertilizers are needed to grow sugar or starch crops to make ethanol, whereas methanol can be produced from lignocellulose (woody) biomass.
Looks like what it was produced from makes it a biofuel or not. Now all we need to build is a portable nuclear reactor. Looks like a project for the 2016 BBB.

the main problem with methanol is the fact that it burns with an invisible flame. the main problem with a nuclear reactor is they are difficult to turn off, so you would to have a large tea pot to use all the spare heat. this could prove costly in tea, plus you would have a large pile of used tea bags as well as spent fuel rod to dispose of. you could of course use the used tea bags to produce some of the methanol. not sure how much you could make though. i am sure the ligmun % of tea is on the web somwhere.
-
Using the used tea bags would be in keeping with the Ethos of bio diesel as it would be bio methanol. Now to use up some of the excess energy from the portable reactor all we need is a Delorean and a flux capacitor. Or falling that an old mot failure with a tank full of newly made bio methanol and someone to light the fuse. Both have the same end effect in a flash of burning tyre tracks a spinning hub cap and no more car, or fuse igniter.
-
Someone to light the fuse.

My thoughts exactly.

You build it I'll drive it.
Note to self : No, No, No you silly fool, never say you'll drive anything that Arrash has built.
If the rest of you build it I'll drive it.
Strangely I still don't feel confident with this statement either.
Count me out, I'll not be driving anything faster than a snail smoking dope, I'll stick to my Disco then.

Mark is your disco as slow at that.

Your far safer taking the Arash option ... it's got to work before you can drive it!

You make a very good point there.

No. I overtook the snail yesterday, but it's taken three weeks to do it.

Ah well, look on the bright side, at least the neutron bombardment will keep him warm. It's kinda like a cabin heater. Wombles make great neutron moderators, so long as you keep the reactor away from criticality, as they perform less well when they form steam voids while boiling.
-

Don't worry, with Arash's stick welding at least you'll have built in burst panels when, ahem, IF the reactor ever has a prompt criticality excursion!
-
So we're back to boiling the Womble then.
That's so last year.
-
Well, we had a go at slow simmering him this year at least :D

only if we used fairtrade organic tea. that would of course raise eyebrows at the local organic stall at the farmers market when you turn up with a wheelbarrow and explain you need to feed your nuclear reactor.

Get scrounging boys Need vacuum chambers, and as for tig welding it bahhhhhh if mma is good enogh for a turbo jet is good enough for a fusion reactor!

They make it sound so hard. You only need a few plastic bottles, some string, plastic pipe, twisty cable(assorted colours to make it look less home made). Wood for the frame work. And what looks like a kettle. This is obviously for water cooling and making the tea to help with the methanol production side of things. They also speak of a video camera. This is very important as we need to be able to see when we reach critical from behind the wind break and also to post the results on here afterwards.

Womble will, in full tradition, take cover behind a fuel can for protection.
As a side note, I've always fancied building a Fusor

a friend of mine made one. the difficult part is creating a decent vacuum and maintaining it. i have a vacuum pump and a diff pump if anyone want s to try. you need a a cheap source of silicone oil and fittings. the heater on the diff pump needs replacing. £100 for both.
his fusor was chucked in the skip at uni but i think he rescued it. may even still have it. could try and find out if anyone is serious about it.

Fusion is for pusses we want Fission.

Maybe a "Challenge" at next years VA? :)
