Cyanobacteria use phycocyanin for photosynthesis, as an accessory pigment to chlorophyll. A number of pigments can serve accessory to chlorophyll, and there are several types of chlorophyll. Larger multicellular organisms such as trees other macroscopic plants can use a number of these pigments together to capture a broader range of the EM spectrum and therefore more energy from sunlight. Cyanobacteria use only a narrow range of the EM spectrum for photosynthesis because they use only a narrow range of pigments. I was given the benefit of the doubt in my calculation of the best-case scenario, but logically the energy efficiency therefore must be FAR below the photosynthetic limit of ~14%, which makes this company's claims thermodynamically impossible and patently absurd. http://en.wikipedia.org/wiki/Photosynthesis#Efficiency http://en.wikipedia.org/wiki/Cyanobacteria http://en.wikipedia.org/wiki/Phycocyanin http://en.wikipedia.org/wiki/Accessory_pigment

typo shows "10,000" gallons instead of 15,000, but calculation is still correct...

Definitely too good to be true. The energy contained in 15,000 gallons of biodiesel ~= 10,000 gallons x 133,000 BTU/gallon x .000293 kwh/BTU = 0.58 MM kwh The energy falling on one acre of land in the tropics ~= 5kwh/m2/day x 365 days/year x 4046 m2/acre = 7.4 MM kwh/year/acre So they're capturing 8% of ALL solar energy falling on each acre of land in their fuel, assuming they are in the tropics and not in the continental United States. The efficiency limit for photosynthesis is around 14%, which isn't calculated on a per-acre basis, but on a molecular exposure basis. Even if you could cover each acre with pure chlorophyll, the conversion efficiency would not exceed 14%. So they are claiming they will exceed 50% of the theoretical photosynthetic limit AFTER all the energy and efficiency loss of processing, for a net yield of 15,000 gallons? Total BS. If they claimed 1000-2000 gallons, maybe, but with their claims you can bet it's a pump-and-dump green stock scam.

Oops, my bad, I read 40,000, not 20,000. So their actually at 10% efficiency, which while unlikely at least has the merit of not being theoretically impossible.

The energy contained in 40,000 gallons of B85 biodiesel = 40,000 gallons x 133,000 BTU/gallon x .000293 kwh/BTU = 1.55 MM kwh

The energy falling on one acre of land ~= 5kwh/m2/day x 365 days/year x 4046 m2/acre = 7.4 MM kwh/year/acre

So they're capturing 21% of ALL solar energy falling on each acre of land in their fuel. The efficiency limit for photosynthesis is around 15%, which isn't calculated on a per-acre basis, but on a molecular exposure basis. Even if you could cover each acre with pure chlorophyll, the conversion efficiency would not exceed 15%.

This is therefore a green scam, undoubtedly designed to temporarily pump the company's stock. The last big one I heard of to do this was Valcent Technology's subsidiary Global Green Solutions. Don't believe the hype, especially when it's physically impossible.

"We require our suppliers to treat all workers with dignity and respect"

Because nothing says dignity and respect like working in a sweatshop and being paid pennies an hour...

Not complete? No shit.

I downloaded Windows 7 RC and for most stuff it's actually fine - I'm using it as I write this. Not unbelievable, but quite good ... once it's working. Fast, pretty stable, all that stuff. But some serious problems getting it working.

First, the activation key didn't work for me. I did it all legit: downloaded and installed W7 from microsoft.com, created a live.com ID, got the activation key, pasted it in and "we're sorry, the activation key you entered is not valid for this version of Windows". Just plain broken shit, no excuse.

Dude, if you can't fucking get your basic shit together, why wouldn't I just use Ubuntu? With Linux, if it doesn't work at least I have the consolation that it's free.

It's like test driving a prototype Chevy and the fucking _key_ doesn't work. Pro Tip 1, you moron engineers, the FIRST thing you make sure works on a new car/OS/whatever is the FUCKING KEY.

The comedy continues. There's also a bug in the W7 RC that causes the OS to crash when running installer packages off CDs ... from Microsoft... So I, like hundreds of others, had to do a reg-edit hack to install MICROSOFT OFFICE. http://windows7news.com/2009/01/21/fix-for-installers-and-updates-crashing-in-windows-7/

Pro Tip 2, you FUCKING IDIOTS: before you release a new OS for testing, the second thing after making sure the FUCKING KEY works is to make sure YOUR OWN FUCKING SOFTWARE WILL INSTALL ON IT.

Seriously. This is stupidity on the "I forgot to put my pants on before I went to work this morning" level.

"Pass"? That's your argument? It's written on an old piece of paper, therefore you don't need to mount a logical defense of the criticism of privatizing all goods and services in a modern global economy? Since when does any theory, economic or otherwise, get a pass? Oh I know - it's like when Copernicus and Galileo said "The Earth goes around the Sun" and the Church pointed to what was written on an old piece of paper and said "pass".

The truth is, tabloid (i.e. neoclassical) economic theory does a shite job of arguing for privatization of a whole range of public goods and services, particularly those that were traditionally under common property rights regimes.

Any real economist will tell you that most markets must be regulated or else they tend toward inefficiency, that profitable markets are inefficient by definition (because economic rents, aka net profit, can only be extracted from an uncompetitive and opaque market), and many markets - like the ones mentioned by the parent poster - are too inefficient for private ownership at all.

Couldn't agree more. iPhone works like complete shit where I am unless I log into my home wireless network with cable internet. On 3G it's slower than 14.4 modem. The internet is virtually unusable for anything but gmail. Weather info almost never updates. The iPhone has great potential, but in my experience it basically just sucks shit in real life when running on AT&T's network, and isn't worth the money - especially since it's far faster to text with a full qwerty keypad.

I'm actually surprised at how confident and competent the NSA seem here

No offense to West Point and the other military academies, but I'd like to see NSA take on the top team from MIT, Cal Tech, etc and see how they fare before putting total confidence in the NSA.
