Must see doco

and Al Gore is no where in sight
Just watched it, well worth it to see the perspective.
My favorite is this page http://www.lifeaftertheoilcrash.net/SecondPage.html about alternatives to oil and why they are next to nothing.

Make crude oil from algae...this tech has legs, and may be part of the solution.

The site I posted has a chapter "What about Biodiesel?".

Its not biodiesel, its green-oil.
That is...
refined into gasoline, jet-A, ect...
using current/existing refineries
that is consumed by existing planes, trains and automobiles.
produced using NO arable land
produced using NO potable water
feedstock is sunlight and CO2 and WASTE water.
WILL NOT displace farmland
WILL NOT harm drinking water supplies.
But...thanks for reading the site I posted. I read your links, you're an alarmist.
IF you are NOT part of the SOLUTION
YOU are part or the PROBLEM!

First thing I look into when discussing a particular alternative energy is - what is the source of the energy? In the case of green-oil it is solar energy.
From here you can see the problems it brings. There are two main interconnected problems with solar energy:
1) it has limited potential (you cannot force sun to give more energy)
2) thus you need to use extremely large territories covered with solar energy equipment.
Now what kind of solar energy equipment does not matter. Be it algae based or photovoltaic modules. The most important characteristic is - efficiency. For example, the record in solar cell is 40% energy conversion efficiency by Boeing-Spectrolab. Algae bioreactor efficiency currently is only 15%. So you can see who's the winner. These numbers deal with the potential part.
Now the second important part is land related. I think these two quotes will speak for themselves:
Solar compared to Gasoline
The amount of energy distributed by a single gas station in a single day equivalent to the amount of energy that would produced by four Manhattan sized city blocks of solar equipment. (There are over 170,000 gas stations in the U.S. alone.). Source: http://www.energybulletin.net/node/3624
and...
Low starting point for industrial solar
It would take close to 220,000 square kilometers of solar panels to power the global economy via solar power. This may sound like a marginally manageable number until you realize that the total acreage covered by solar panels in the entire world right now is a paltry 10 square kilometers.
