--06.10.2012--Businesspeople with good hearts looking to make a difference usually start with three questions: "How can I give back?" "How do I pick a good cause?" and "What skills should I contribute?" But the businesspeople I've met who have made the biggest contribution usually started with a different question: "What can I get?" As a result, they engage more deeply, contribute more of their skills, and do so for longer duration. #cause
--06.10.2012--It is thus flawed, a weightless, overly romantic attempt at economic analysis, special only in that it is not an entirely boring read. #weightless

--06.10.2012--I'm not entirely sure what literary fiction is "supposed" to be...but it is something that we can recognize when we read it, and in terms of speculative stories, it's a suggestion of internal struggle. #weird

--04.23.2012--Scientists published their work in journals that only scientists read, classicists in volumes that only classicists read, and engineers in blue books that no one read. So the reference book was born---the compendium of facts, the chrestomathy of passages, and the anthology of extracts---by which the rest of us could learn and use the information that print technology was producing, filling bookshelves that could be measured by the mile. #wikipedia
--04.23.2012--
The numbers don’t work.
1 acre = 4000 square meters
8 hours a day max sunlight (overestimate)
1kw per square meter sunlight (overestimate, ignores clouds)
Thats 11680000 Kilowatt hours per year of sunlight max
i.e. 11 mega watt hours
1 litre of petrol contains 9.7kwh of energy
So even at 100% algae efficiency with 100% of the light from the sun, we’re talking 1204 litres a year of petrol per acre not 20000.
A more realistic measurement is 300 litres per year, which is 2 barrels of oil per acre per year. Pretty good, but no way near as good as he makes out.
84 million barrels a day consumed, so we’d need 365*84/2 million acres = 15 billion acres
So we’d need 23437500 square miles. Area of United states is 3537441 square miles, i.e. an area near the equator 7 times bigger than the United States to grow enough algae just to replace the petroleum we use (never mind the natural gas).
