Thoughts about sphere worlds

[Karibu]

Omnicron has good point. Sphereworld would only be the biggest atomic bomb ever made. Unless there would be the way to gather all that extra energy and lead it to some place else.

In addition Omnicron suspected that we get about 1% or less of sun's energy, we can check with simple math:

The amount of surface of earth to face us is equal to area of our planet when you cut it half in the middle (yes, the area actually having sunlight is bigger because earth is not flat and not always directed towards sun, but the effect is less on those "not directed towards sun" areas. Equator gets near 100% of the energy but north pole and south pole gets only fraction of that). The 100% effective area would be as follows:

pi~ 3,14159265359
r = radius of our planet (12756 km /2)
pi*r^2 = 511185932,523 km^2

Then we imagine a sphere which radius is same as is earths distance from sun.
r = radius from sun (149,6*10^6 km)

The area of the sphere would be then:

4*pi*r^2 ~ 2,812*10^17 km^2

Now we simply calculate how much is the amount of "earth 100% effective area" of "sphere world aea" which get the 100% of sun's radiation.

Earth sun facing area
--------------------------
sphereworld sun facing rea

~ 1,818 *10^-9 = 0,0000001818 % of sun energy.

On other words, there could be 550 million areas size of our "100% effective areas" in one sphere world. SEIV sphereworld seems to be utterly ineffective construction. Damn engineers!

That is the amount of the energy earth receives from the sun. The calculation is rough, but decimals are right. If I am not wrong, of course.
