Hi,
I have a question for the experts in safety.
I was researching solar power for my house this evening, and started calculating some stuff. But I have to be wrong at this somewhere. Because the results are nuts.
Sunlight on a good day: 1367 Watt/m2 = 0.136W/cm2 = 136mW/cm2
Your eye: 7mm. so the surface is 3.5mm x 3.5mm x 3.1415 = 38mm2
Your eye gets 38mm2 x 1.36mW/mm2 = 51mW
I told you the result is nuts...
And I thought my 30mw laserpointer was dangerous
Seriously, can somebody tell me where I am wrong ? I know that looking at the sun isnt very wise either, but 6.6 billion people do it everyday for a fraction of a second.
here is the suns spectrum:
