What if we invent a way to harness abundant energy source like nuclear
fusion,

once done the energy will be very cheap and a lot of wastage will
happen, cuz it is cheap and there is not a restriction of fuel
shortage(oceans).

by doing so will we not heat up earth by our own energy created
instead of co2,
cuz this energy was not existent,it was packed in matter which we are
releasing,

apart from sun heating the earth we will also heat the earth from our
fusion produced energy cuz no mater what the conversion is(to
light,motion,air conditioning etc),it is ultimatly going to be
released to the environment after what ever is done(cuz of
Thermodynamics law 1).

and as i, u and history knows now humans are restricted by energy,if
that is solved we will not stop unless we make the earth a sun, so
that we meet our needs ohh sorry greed....

so are we not seeing solution to a current problem of global warming
in a much more greater problem of global heating???


i am not talking about entropy,i am talking about
"energy can neither be created nor destroyed"

what ever energy we have here on earth is from sun,

Now if fusion comes into picture we are going to create tremendous
amount of energy from matter which was not there...
by tremendous i mean humangus(to satisfy our greed cuz its cheap n
abundant )
which will be ultimately released to the environment...

Well, it's not guaranteed there is no restriction on fuel shortage, even
though it's coming from the vast oceans. We didn't think there was ever
going to be a shortage of oil, since it was coming from under the land.
We didn't think there would be a shortage of Uranium either, but it
looks like there may only be enough U-235 to power us for 40 years, if
we switched to fission whole-hog (which we haven't done, thank god). If
U-235 ran out, then we'd have to switch to the far more nasty Plutonium.
Plutonium is made from a reaction of the far more abundant U-238, so
this type of Uranium won't run out as quickly; but U-238 is not nearly
as radioactive as U-235, so we turn it into the nasty Plutonium to get
it to become radioactive.

The type of hydrogen we need for fusion is deuterium, which is the heavy
hydrogen that makes heavy-water heavy. Currently we use heavy water
simply as a nuclear regulator in fission reactions, so any heavy water
that comes in, goes out unchanged. If we switch to fusion, then that
heavy water goes from being simply a regulator to being the fuel itself.
Even though there is plenty of heavy water in the oceans interspersed
with the regular water, who can tell if it too would become scarce?

Deuterium fusion is an easier reaction than regular hydrogen fusion. All
of the fusion work being done right now is based around deuterium,
rather than regular hydrogen. If we ever get deuterium fusion right,
then hopefully we can get to the next step and get hydrogen fusion right
too. Then we can use all of the hydrogen in the oceans, and not just a
specific subset. The only place where there is regular hydrogen fusion
going on right now is in the Sun.

That's really what's happening right now anyways, even in chemical
reactions. A chemical reaction might release 0.001% of the mass into
energy, while a fission reaction might release 0.01% of the mass, and
fusion might be 0.1% of the mass. A matter-antimatter reaction will
release 100% of the mass, of course.

And despite all of the hype over global warming, we've been heating up
the Earth since we invented fire. The Earth then finds a way to release
that heat through radiation into space.

Well, we will only produce as much heat as we need on Earth. Chances are
that a lot of future uses of fusion will be outside of Earth, in space,
to power our spacecraft as we venture into interplanetary and then
interstellar space.

Well that's a bit of a dramatics. Human energy demand will go up
inevitably, but I don't see it being restricted to applications just on
the Earth any longer. With that kind of power at our disposal, we'll be
ready to spread that energy around the whole solar system, if not further.

How do you get an environmentalist to support and indeed demand nuclear
power? Tell them it'll alleviate global warming. :)

Energy cannot stay put like that: you can't have static energy unless
you turn it into matter. Otherwise, energy will always radiate away in
the form of light. In fact, mass is just a special highly-packed form of
energy. So congratulations, you're a being of pure energy.

Entropy is the way of the universe.

I think there was an paper pentioned in New Scientist some time ago about
this. I believe it concluded it could be a concern but only if poulation
growth rates continue to be high.

When I dream, I have a pony. And it's radiation free also.
