Nuclear Weapons

France has reduced it's Carbon emissions by 90% through the creation of the largest group of nuclear reactors per citizen. They produce 77% of their power this way.

The United States ranks first in total kiliowatt hours at 101,000 MwH's but only produces 20% of our power this way (shamefully).

Slovakia is the most balanced user with about 50% of their power from this awesomely affective method.

Under the correct conditions, indefinitely.

While the mechanics of an atomic bomb can be stored a long time, assuming proper maintenance, the fuel decays noticeably over time. After about a decade of storage, the fuel has naturally fissioned enough to produce "pollutant" fission by-products which ruin the bomb's explosive potential. That is, the fuel naturally decays, and the natural decay atoms will inhibit the proper chain-reaction needed to have a usable weapon. So, the fuel will last about a decade before it needs to be removed and reprocessed.

Also, if the fuel core is stored in the weapon (i.e. the weapon is stored "fully functional"), the residual radiation and heat that the fuel decay gives off causes significant problems for the weapon: the fuel configuration itself may change slightly or crack, the sensitive electronics may suffer damage from the gamma radiation emitted, and the chemical explosives may likewise suffer degradation.

Overall, while the time a given weapon design can be stored varies, and the exact times are of course classified, it seems that discussions about such topics in the open literature indicate that an atomic bomb needs to be serviced and checked regularly (at least every 6 months or so), and that few can be stored for more than a decade before needing a serious overhaul.

they made them out of stone

Carved swords and spears

Sticks and stones have always been available for use as weapons. Either one could have been the first, but the stick may make more sense.

an arms race

to intimidate the opposistion, fear is a powerful weapon it can make your opponent make mistakes during a war and it makes them belive that they cannot win

During the Cold War aircraft carriers had a secondary mission of nuclear warfare and its attack aircraft were nuclear-capable. However, it was policy to neither confirm nor deny the presence of nuclear weapons aboard any naval vessel. Pres. George H.W. Bush cancelled the nuclear mission for all naval forces except SSBN submarines. Today there are no nuclear weapons and no nuclear-capable aircraft on our carriers.

MK-I Little Boy & MK-III Fat Man

Yes, dramatically. Especially if we switched to hydrogen fuel cell cars and produced the hydrogen in the nuclear power plants by direct thermal conversion without generation of electricity.

the answer to this question is simply no. The mere fact that nuclear weapons were developed until the 1940's makes it just a little bit hard to use a nuclear weapon in WWI (1914-18)

To protect the country that made them or most countries use it to gain more protection of other contries or to threaten other countries. :)

as per today's update Russia has more than 3000 nuclear warheads(deactivated),1200 warheads ready for use. US has nearly 2400 nuclear warheads stockpiled and 400 nukes ready for use.

There are several Asian countries that could be considered secretive and who use nuclear power. For instance, there are North Korea and China.

Plutonium-238 power cells were used to power cardiac pacemakers some time ago (it prevented an operation to replace the battery -- back then, batteries weren't as efficient), but nowadays, long-life lithium batteries are being used.

Plutonium is toxic to the body, radioactive effects aside, so it's not used in medicine that I know of. Its half-life is somewhere in the neighborhood of 87 years, and generally you don't want something that takes that long to decay in the body.

yes , India is truly with all for nuclear disarmament but at the same time it cannot disable its nuclear powers in this time of developing technology. \\\\\\!!!!.

Probably not but it wouldn't surprise me

Japan

You put a detenator inside and you set it of.

We did it to ourselves plenty of times from 1951 to 1963 at the Nevada Test Site. The fallout hit all lower 48 states and parts of Canada and Mexico.

Most nuclear power plants currently operating in the US are classified as pressurized water reactors (PWRs). These reactors use water as both a coolant and moderator to generate electricity through nuclear fission. PWRs are the most common type of nuclear reactor in use worldwide.

Started in 1946 continued about every other year until early 1960s.
