Not sure about enzymes?

Both of those methods use alcohol esterification... I'm asking about the enzyme method that Bicycle Bob suggested.

lipase enzyme

theres also a pdf on it, but it cost money

As a long time home brewer, I think the solid catalyst idea and the enzymatic/lipase approach are about like making practical electricity from a hydrogen fusion reactor. We see periodic press releases about how great it is, and how soon it's coming. Just another 2-3 years and it will be on the market. Electricity too cheap to meter. Blah blah blah.

It will be great when it gets here, I'm sure.

The glycerin byproduct apparently makes an excellent feed additive for cows if you remove the extra methanol first.

It also burns well in my wood stove in a small steel box about the size of a shoe box. I mold it into 1 liter blocks and burn it with wood. It reduces my wood requirements about 40%. It does burn hot, being in the alcohol family, so you need a stove with good combustion air control and a good damper in the flue as well. Use at your own risk.

Finest regards,

Makes good soap, too. Also OK fertilizer, I'm told. There are 1,000 potential uses for the waste stream, actually.

Where have you people been the last 9 years???

Solid Catalyst to Convert Algae into Biodiesel - Oilgae.com

I can't located the specific one now but originally it was announced on the original from the fryer to the fuel tank forums about several scientists that had a solid catalyst method where the catalyst was not used up but their funding was pulled by the government, a few years later a company offering the systems large scale popped up. This has been at least 4 years ago and the fryer article was probably 9 years ago.

Anyway there are MANY solid catalyst methods floating around, I just can't find the one I remember. I will keep looking

Please do - interested.
