Biodiesel from Algae

Funky Fuels | The Big Money:

"Algae

Because it grows quickly, has a high oil content, and needs only sunlight and water, algae looks promising as a source of both ethanol and biodiesel. It also serves as a filter for dirty water and as a carbon sink. Ideally, an algae farm could be located downstream from a large-scale farm or factory, where it can clean the water of pesticides, carbon, and heavy metals.

Estimated production cost: $1 to $2/gallon.

Prospects: Good. Algae is cheap and easy to grow."

That sounds like a possibility...

I remember seeing that a guy was doing this himself at home, on a small property.

I think this is him:

And a Google search of homemade algae fuel brings up quite a few results including this video:



While that set-up looks interesting, I'm sure it has a long way to go before it produces fuel on a usable level. There are currently books on the subject, but I've seen the information selling at $100, and that's a bit steep for an e-book in my mind. That type of price-point online makes me trust it less for some reason.

And if you aren't ready for using algae to produce biodiesel (I know I'm not), then take a look at the setup in this video.
