India is suffering from severe power-cut problem (especially the villages and small towns).Is there any method by which energy can be bought from those countries which don't have this problem and have enough money and resources to generate power?Maybe by storage of energy in large capacitors or so.....is it possible?I don't have any idea.Your comments.

I've been told, but not by any reliable source, that urine is hygienic. That makes no sense to me. So here's my list of questions about that:
1. Is it true that urine is hygienic?
2. What does hygienic mean in this context?
3. If it's true that urine is hygienic, why are we supposed to wash our hands after urinating?
4. If it's true that urine is hygienic, what chemical in urine makes it that way?
5. If it's not true that urine is hygienic, why do people believe it is?

Proof for hyperbolic universe?
we heard that universe is elliptical
In Elliptic space, every light ray is a geodesic line. Light rays will be circling the geodesic line forever unless blocked by some object. We can see the same light ray of star many times, because the light ray circles in the space forever. Also, we can see the same star from opposite directions many times, because the light ray from other side of star circles in the space forever too. Since the Universe was at least many billions old. All the lights of the sun and stars had collected so many billions of years. The Universe should be so bright even at nighttime. Of course that is not the case. So the possibility of the Universe is only Hyperbolic Universe.

This is actually a correct version to my previous question:
if x is more than 0 and less than 180
then sin x = y, means x has two values
while tan x = y and cos x = y
x only has one value?
is it correct?
