Thanks to discussions/links at Instapundit and Jerry Pournelle’s site I got interested in how much space would you need to replace the world’s crude oil consumption with algally produced oil. From this US DOE graph we see that world crude demand is c. 82M bbl/day. which equates to some 30 Billion bbl/year (365.25*82 = 29950.5). According to various places ( google search ) one barrel of oil makes 28 gallons (US) of gasoline/petrol and contains 42 gallons of crude. Hence depending on how you do the calculation we need either 840B (28*30) or 1260B (42x30) US gallons of algal fuel per year. So how much algae is needed for that?

Mark Helprin - Greedy or Idiotic?

Obviously, as an author, Mr H will benefit from this extension but I’m not so worried about the greed he exhibits as the basic errors of concept he demonstrates. Essentially Mr H thinks that because Copyright is a form if "Intellectual Property" it should be treated like real property and be a p... more

This is something different. Last weekend I ran around Le Bar sur Loup and found this. Someone has taken the time to try doing topiary with an olive tree. It seems to work well, but I think it has taken quite a while to get to this point.

Wolfowitz vs Pillock-Brown

Melanie Phillips has commented on the Wolfowitz World Bank "Scandal" and links to two articles that add fuel to my suggestion yesterday that the scandal is being pushed by the corrupt and/or their defenders. The most interesting in that regard is in Canada’s Financial Post . First the article explains that currently the World Banks major competitive advantage appears to be that it doesn’t ask nasty questions about how the money it lends is spent ...... more
