That's pretty good. Compare this with our biological friends: plants like
sugarcane usually get around 4.5% efficiency with photosynthesis and a
yield rate of 1/10th that. So, with the sun giving averaging us 100 watts
per square meter 24 hours a day/365 days a year, we would get about 400
milliwatts of sugar per square meter...
So how many potato plants does it take to run a Debian Linux box on either
technology?
