Mr Biodiesel

It's a sort of Mr Biodiesel which you feed with waste oil and methanol and it chugs away making a 50 litre batch of fuel. Kinda like a bread machine for recycling fuel. This sort of consumer-grade processor's a great idea and I think it will have a big market.

On a large scale I agree.
Micro-renewables have to be the way to go. That will work. I just wish home design was already doing it.

On a large scale, biomass doesn't scale up well, nor does hydro. Wind can. Tidal is like fusion, permanent Future Tech. I think it's pretty clear that the govt want to go towards nuclear + renewables.
