At 100% efficiency the energy from sunlight in North America gives about 600 gallons of oil per acre per day. I forgot the "per day" bit.
If the "pond scum" process is 5% efficient at converting sunlight to oil then that could make about 10,000 gallons per year. Of course it's a "big if".
Apologies for this. I didn't spot the error because my result was in line with the figures for the real-world crop yields - but clearly they are very inefficient at converting sunlight to oil.
"Soybeans can give you 50 to 60 gallons of oil an acre compared to 75 to 125 gallons for canola, but algae is almost limitless because it grows so fast, so potentially you could get 10,000 gallons per acre."
At 100% efficiency the energy from sunlight in North America gives about 600 gallons of oil per acre. Not 10,000. Also "pond scum" will be much less efficient than this.
So the solar energy which hits an average US acre in an average day is about
= 250*4046*24 / 1000 KWh
= 24,276 KWh
And the energy in a barrel of oil is about
= 5.8 * 1,000,000 * 1055.87 / 3,600,000 KWh
= 1,701.12 KWh
This means the solar energy which hits an average US acre in an average day is about
= 24,276 / 1,701.12 * 42 gallons
= 599 gallons

America doesn't need a war on terror, it needs a war on butterflies.

Suppose... x/0=y x!=0 Which means... x=y*0 x!=0 Which means... x=0 x!=0 Which is never true, QED, so "x/0=y" does not generate a value for y when x is non-zero.
Suppose... x/0=y x=0 Which means... x=y*0 x=0 Which means... x=0 x=0 Which is always true, so "x/0=y" could generate a value for y when x is zero
The equations tell us nothing about what this value is, so I'd prefer it to be "0/0=unknown" rather than "0/0=infinity".

Personally, I would rather have confusing choice rather than have to eat a bunch of bland tasting Communist O's that have a picture of Stalin on the box.
Unfortunately capitalism gives you those same bland-tasting O's, except with added sugar frosting and a huge choice of cartoon characters on the box.
For genuinely informed choice, they should decorate each supermarket aisle with a different life-size photo of a someone in their underclothes, demonstrating how you'll look if you mainly eat the food sold in that aisle.
the first institution in the world whose contents, with the exception of a few turtles swimming in an artificial pond, are entirely fake.
Nice trolling in the original post, but this museum was built a couple of years earlier. Probably there are thousands of fake institutions across the world, given how many powerful people such as Stalin have believed in pseudo-sciences such as Lamarckism down the years.

Here's the math: in North America the average insolation [sunlight] at ground level over an entire year (including nights and periods of cloudy weather) lies between 125 and 375 W/m (3 to 9 kWh/m/day)
http://en.wikipedia.org/wiki/Solar_power
1 international acre is equal to:
4046.8564224 square metres
http://en.wikipedia.org/wiki/Acre
1 barrel of oil equivalent = 5.80 million Btu.
mean Btu 1 Btu = 1055.87 J
1 kWh = 3.6 x 10**6 J (exact).
1 barrel = 42 U.S. gallons
http://www.aps.org/policy/reports/popa-reports/en
So the solar energy which hits an average US acre in an average day is about
= 250*4046*24 / 1000 KWh
= 24,276 KWh
And the energy in a barrel of oil is about
= 5.8 * 1,000,000 * 1055.87 / 3,600,000 KWh
= 1,701.12 KWh
This means the solar energy which hits an average US acre in an average day is about
= 24,276 / 1,701.12 * 42 gallons
= 599 gallons

You should have offered to exchange a Wii for it - then everyone would have been happy.
Also, did you get her autograph? You could sell that on ebay too because it would be the closest that most of us Brits will get to a PS3 this year.
Ironically this game is proof of that. See also War on Drugs, RIAA, Oil Business.

The Wii looks very good, but to be honest I think the DS is the better choice for adults, though it's not "next gen", because you can take it to work.
