I'm not surprised. Biodiesel (B100) has such a low vapor pressure it isn't even classified as a flammable liquid. I think it would be very difficult to get biodiesel to burn in a camp stove.
Ok, I watched the video - he isn't using biodiesel - he is using cooking oil. The stove is designed to be used in third-world countries to replace highly polluting charcoal burners. This is a good idea, but he shouldn't be spamming for funding on ecomodder I think, no matter how worthy an idea it may be.

For an alcohol stove, you can use a soda can instead of a fancy $100 gizmo weighting over a pound. Plus, alcohol isn't that cheap, at least where I live. 1 liter of diesel or gasoline here costs around US$1, biodiesel a few cents less, while a liter of alcohol goes for somewhere around US$30.

I made one of those aluminum-can camping stoves last year to use for bicycle camping and it works great. Methanol here in the US is only about $6/liter. For fuel I use gas-line dryer that removes moisture from fuel tanks - it's pure methanol and comes in 12 oz bottles for $3 and is available in any hardware store, and lasts me about 3-4 days of camping. Maybe specialized camping fuel is $30/liter here, but I don't use it since its just dyed methanol.
