Nuclear Reactor, What Do You Know About It?

I am much scared about nuclear reactors. In Italy we had a petition about nuclear energy in the late 1986...or 1987 and Italian people voted NO. It was right after the Chernobyl incident...so we was very scared. I am still scared that core could meltdown again in some reactors...maybe still russian ones. Do you know that in Russia they still have 17 reactors, still of the old type, that can have the same incident as Cernobyl? I was in Russia last summer...and this is a true thing!:-/ So bad! I've heard, when I went to Germany, that Germany was trying to abandon nuclear and only use eolic generators (wind power) or other "clean" energy...isn't true?!? I would go away...I don't trust nuclear...

hehehe....i think you more know about it my friend. As long as I know, it takes the energy yield from fisi reaction. Am I right or wrong?

Unfortuantely nuclear reactors are always dangerous. And the whole world could be destroyed by one of them. But, nooooo! They had to make many in order to evaporate us all! See ya!

Wave power.
refers to the energy of ocean surface waves and the capture of that energy to do useful work - including electricity generation, desalination, and the pumping of water (into reservoirs). Wave power is a form of renewable energy. Though often co-mingled, wave power is distinct from the diurnal flux of tidal power and the steady gyre of ocean currents. Wave power generation is not a widely employed technology, with only a few experimental sites in existence.

The fundamental challenges of wave power are:
- efficiently converting wave motion into electricity... generally speaking, wave power is available in low-speed, high forces and motion is not in a single direction. Most readily-available electric generators like to operate at higher speeds, with lower input forces, and they prefer to rotate in a single direction.
- constructing devices that can survive storm damage and saltwater corrosion. Likely sources of failure include seized bearings, broken welds, and snapped mooring lines. Knowing this, designers may create prototypes that are so overbuilt that materials costs prohibit affordable production.
- low total cost of electricity... wave power will only be competitive when total cost of generation (p/kWhr) is reduced. The winning team will be the one that develops the lowest-cost system (which includes the primary converter, power takeoff system, mooring system, installation & maintenance procedures.... )

Wave power could yield much more energy than tidal power. Tidal dissipation (friction, measured by the slowing of the lunar orbit) is 2.5 terawatts. The energy potential of waves is certainly greater, and wave power can be exploited in many more locations. Countries with large coastlines and strong prevailing winds (notably, Ireland and the UK) could produce five percent or more of their electricity from wave power. And excess capacity (a problem common with intermittent energy sources) could be used to produce hydrogen or smelt aluminum.

hi yainal,
the solution for nuclear crisis will never end, if no proactive action been taken.
Nowadays people are not interest to discuss further on this topic.
But recently Malaysia going to built new power reactor for electric electricity.
My opinion very open on the reactor.
So i agree with the reactor.
To me reactor will give high feedback if there are someone knows to use it.

Regards.
