Check back through the posts. You will find similar comments. I hope you graduate from Primary School.

Hi Bam

I wish some one would offer me squillions to do some research on the selection of algae for carbon capture.

While working in the mines I noticed that where ever we built a pond algae would soon colonise, didn't seem to mater how saline the water was.

There is probably a huge spread of genetic variability in our wild algaes

if we could harvest them, and select the traits we were looking for, perhaps we could utilise saline ponds (which we have in excess) to soak up some CO2 from the exhausts of our power plants.
Perhaps the algae could be harvested via pumps and filters, the hydrocarbons removed from them and the waste returned to the saline ponds as a nutrient for more algae.

I see this as one possible stopgap measure until we can move a bit further away from our carbon economy.

Algae is indeed a viable source of biodiesel, if you have the right strains. Some algae can be as much as 50% oils by mass.

Widescale Biodiesel Production from Algae (originally published by University of New Hampshire (US) Biodiesel Group)

What is probably not viable is the idea of growing plants like canola for biodiesel, especially if those plants require arable land.

Thanks IV and Bam

Got to be careful when scientists design things, they can over complicate things.

They need a farmer on the team, that can grow algae in the most simple and cheap way.

Our North West would be perfect for growing algae, the only thing missing might be the CO2.

I have been considering WA's potential for producing artificial fuels for some time. Biodiesel from algae or synthetic diesel by Sunfire's process could both be produced there. As long as the equipment is robust enough to survive an occasional direct hit from a cyclone, WA could be on a winner.

We just need to overcome the Liberal Luddites who insist on a 19th-century approach to energy. ("Coal first"? Really?)

The right method needs to be chosen. Algae for biodiesel cannot always be grown in open ponds because it can be contaminated with undesirable strains of wild algae. Weeds can occur with algae too.

Kelp is a viable alternative. It's very vigorous and easy to grow. It may even offer side benefits - kelp beds attract marine life and could be a boon for commercial fishing by providing shelter for growing fish.

I want to use something that has been degraded or is seen as having no value, old mine sites,

While messing with the ocean has some potential down sides.

There is no reason why we can't do both.

Not to diss what looks like very exciting technology if feasible, but did anyone else giggle when they read this?:

I am sure that a number of people probably did, but that is her name and, as the information I posted was a press release from Audi, I can't imagine that it would be a hoax.
