Le biocarburant aux micro-algues, une alternative au pétrole ?

Le biocarburant aux micro-algues, une alternative au pétrole ? | Sustain Our Earth | Scoop.it

INNOVATION - Fermentalg, jeune société girondine a présenté un véhicule roulant avec un biodiesel intégrant 7 % de biocarburant d’algues, en décembre 2012. Le rendement est trente fois plus élevé que l'agrocarburant issu de l'huile de colza ou de palme et ne nécessite pas de mobiliser des terres fertiles.

Stupidity Is Not A Valid Defense For Us - The Automatic Earth

Stupidity Is Not A Valid Defense For Us - The Automatic Earth | Sustain Our Earth | Scoop.it

If we can't plead stupidity, what else is there? How do we live with ourselves? Is it all the stuff we buy that manages to numb our brains and consciences?

 

When I see a headline like this one at Bloomberg today, World Needs Record Saudi Oil Supply as OPEC Convenes, there’s just one thought that pops into my head: what the world needs is for us to stop doing this thing we’re doing. Even apart from peak oil concerns, it’s obvious we’re going to run out at some point or another, and it doesn’t matter whether that’s tomorrow or at some other point in the future, though we do know it’s not going to take another 100 years, or even 50.

 

And nothing will ever take the place of oil; once those unique carbons are gone, that’s it, we’ll have to find a completely different way of running our societies, and if we’re not smart enough to prepare for that beforehand, we’ll be cats fighting in a sack and use the last scraps to kill off each other. And our legacy won’t be the Greek thinkers and Picasso and Dostoyevsky and Walt Whitman and Maria Callas, since there won’t be the means for our children anymore to share what makes man great between them. Our main legacy will instead be bloodshed, we will have gone the exact same path that any non-thinking or even primitive organism would have taken, who don’t have opera or philosophy or poetry to their name.
