What’s the maximum number of people that could live on the Earth?

A recurring theme in society is that of food shortage. Thomas Malthus is now mainly known for his theory that population growth would outstrip food supply. [0]
As it turned out, human beings are good at making lots and lots of food. [1] But the question is still interesting; what’s the absolute maximum capacity of the Earth?
1. Energy
How might we calculate this number?
One possibility is this: energy consumption. If a human being needs 2000 kCal/day to survive at a normal level, that energy must come from somewhere; but where?
The sources of energy on the Earth itself can be used up; coal gets burned, oil is spent, uranium is fissed. Almost all new incoming energy must originate from the Sun, the Sun produces 1.740×1017 watts of power. [2]
Google thus identifies the maximum number of people we could ever support with only the earth: 1.79655832 × 1015 people. [3] This doesn’t take into account crowding or energy efficiency, but we can know with absolute certainty that without a change in the human species or space colonization, it is impossible to get past this number, which is incidentally about a million times the current population of Earth.
Great Scientific Discovery!

I will do something for the blog, since i’m a stooge. I am going to test a product. I think this will qualify under games and food. Cheng has been up since 3:30 pm on the 16th, its 7:17 am on the 17th. Thats not too bad, but what about during today? Chengameepheus must stay up until 5 pm and will attempt to stay up longer. I’m going to test the new product
I am going to see how long I can stay up. This should be interesting. I will check back in, probably later tonight.
Dec. 17th- (10:25 am)- Despite not feeling very tired, Cheng feels like he should keel over.
I actually haven’t tried an MDX yet, but will.
10:30 am - I was forced to correct a previous statement. I now, have to say i went Mark Henry-style.
Mark Henry

HE’S A MACHINE.
(4:04 pm)- Cheng has managed not to keel over so far. I see cipher’s link, so i must answer. hahahahaahhaahaha, cheese and church. I will chugalug an mdx as a tester before I’m in prime position to keel over.
(9:38 pm)- I had a chugalug of mdx, then if forgot i had it. The one reason you know u’ve had it is because of the ninnish taste. I don’t think it worked too well, i nodded off a few times today, but not for any substantial sleep. “A safety can change the whole momentum of the game.”
Dec. 18th- (12:14 am)- STACKS. My dora isn’t advanced enough to play Fifa 2002 for no apparent reason. I don’t know if i should blame dell, fifa, ea, or some random company.
(2:28 am)- I guess my dora was too fast, won’t last. EA’s ploy is working though, i have a massive urge to buy the reduced price of game, most likely 04, possibly 03. 03 would seem like a minor upgrade. I don’t really think it makes sense to buy a game every year, i would normally go with the combo-pack every 4 or so years. The combo pack puts 4 games in 1, and makes them not so much, but they are a year or two old. Usually they throw in something like golf, but Tiger Woods is a machine. I really have to buy a fifa game, because Chengameepheus already has a disease.
(3:00 am)- The “disease” got me going.
3 Things You probably know about US soccer- 1)Freddy Adu plays soccer (and his age). 2) The US was in the last World Cup and did well. 3) We are in the next World Cup.
3 Things You might know- 1) Landon Donovan- star on US team, played in Germany and in the MLS. 2) Bruce Arena- US coach, spent years at the University of Virginia and a few in MLS before having great success with the national team. 3) The US team finished first in CONCACAF over Mexico (in 2002, US finished 3rd behind Mexico and winners, Costa Rica).
3 Interesting Things- 1)The MLS is developing talent- two major examples being Demarcus Beasley (PSV Eindhoven) and Tim Howard (Manchester United), who are both in europe after starts in MLS (Chicago and Metrostars). 2) US might be developing an interesting niche position. Already at an elite level, goalies seem to be abundant. It all starts with Kasey Keller at the top, and continues with MLS development. Tim Howard, followed by Joe Cannon, Thornton, and others in the MLS. 3) A group of strong defenders abroad, such as Berhalter, Bocanegra, Cherundolo, and big guy Onyewu.
Things to watch- 1) Watch to see how Arena decides to fill out his roster, with more to choose from than ever. 2) Watch how the Czech Republic, Italy, and Ghana are doing, as well as pre-World Cup matches against Canada, Japan, Norway, and Germany. 3) WATCH SOME SOCCER GAMES.
