@frederickgraff they dry it reducing its liquid contains then they use mechanical pumps to apply pressure to it squezzing oils from it because water will dry but the oil will lock into the algae because oils low release rate

Does anybody know how to filter that algae?

@77OM616 There are ten times more processes in refining crude oil compared with digging up coal and burning it. Coal fired power has a conversion efficiency of about 50%, compared to 25% in a combustion engine. I'm not arguing that coal isn't dirty but it's way more efficient than petroleum or diesel. And when you start adding renewables to the mix it gets cleaner again. Even based on the dirtiest coal fired plant on the planet i'ts still less energy than wasting it in a combustion engine.

@DingoBabyEat For what it's worth, coal must also be mined and transported, and it burns dirtier than petrolium products. As a solid, it cannot be piped. (Ethanol and corn also can not be moved through a pipeline) Furthermore, the internal combustion engine is not the most inefficient kind of engine... if it was we would still be using (coal fired) steam power.
Part of the reason that Diesel made his engine was because nothing was on the market that was affordable to operate (efficient)

its great that people are trying and sure we'll see new tech & efficiencies, but short of fission there simply are no viable alternatives to fossil-fuels, at least not for 6.7billion people. 'demand destruction' is what we're in for.

" a better solution would be to use the carbon that's already in the atmosphere'
its Energy , not Carbon, that we need.
having said that agree that piping burnt fossil c02 into algae tanks is a great idea for 'damage limitation'

But the algae could still be used to sequester carbon from any number of industrial processes. It's not a solution in and of itself but it has potential to clean up some dirty industries in the short term. Petroleum is not great! - the energy that goes into extracting, trucking, shipping, refining, storing, trucking, pumping and then burning in a combustion engine (which is the most inefficient kind of motor). Coal fired electricity is way more efficient than that

growing algae is pretty simple, but the major question is energy input and ouput for extracting the algae. for most industrial production, the major fuel source is still from fossil fuels. algae fuel may not be a viable source of energy if the energy input is more than the output. petroleum is great simply because all the energy input is free from years of under the earth pressure. however

to grow algae is pretty simple job but the question is how to convert it into biodiesel in an economic or cheaper way ?
