Anti-Matter vs Solar Energy

Wikipedia puts average daily solar irradiance at 21.6MJ per square meter. Multiplying by the surface area of the Earth and dividing by two (since only half the planet is facing the sun at a time), we get 5.48x10^21 Joules.

A kilogram of antimatter would annihilate with a kilogram of matter, releasing energy according to e=mc^2. For the total 2 kilograms of mass, we get 1.78x10^20 Joules.

So by these estimates, it would take roughly 30 kg of antimatter to equal the energy the Earth receives from the Sun in a day.

The solar energy intercepted by the Earth at any given time is around 173,000TW (a calculation using the solar constant, radius of the earth and that of the sun)..

Energy produced by 1kg of antimatter reacting with matter is around 600MJ (easy calculation of e=mc^2)

So in an extremely tiny fraction of a second, the solar energy wins. You should be able to work out the numbers to break even (divide the power of solar energy by the nergy of the kilogram of antimatter to get how many times more you need for an equality during one second)

>Energy produced by 1kg of antimatter reacting with matter is around 600MJ (easy calculation of e=mc^2)

1 kg of matter + 1 kg of antimatter = 1.8*e17 J

E=mc^2
E=2 kg*9e16 J/kg
E=1.8e17 J

derp, I forgot the kg is the base unit for mass >.>

So it would take more like 30,000 kg of antimatter.

That's a lot indeed.

>So it would take more like 30,000 kg of antimatter.

30K kg of matter and 30K kg of antimatter would produce the same amount of energy as 8 hours and 40 minutes of sunlight falling over the entire planet.

>no science or math background
acquire background fgt pls

Is it true that antimatter goes "back in time"?
I call BS, but I'm ignorant.

>>9099287
no

>>9098965
Power means usable energy. Since we can't really use antimatter energy in a really useful way because it's just gamma radiation, no matter how much antimatter you get, sunlight aways wins.

>>9099287
Antimatter is mathematically equivalent to time reversed matter, but the physical importance of this is debatable.

It's modeled as such when using Feynman diagrams in QED. Feynman seemed to think there was a significance to this, but again, this is debatable.

That triggered me.
