The Greatest Engineering Achievements of the 20th Century

[iLOVENATURE2011]

without those great engineers, maybe there are no computers...thanks to them and their great minds...=)

After what happened in Japan, I doubt confidence in nuclear technology is growing.

[hocoking123]

@dave474c maybe for coast cities

[dave474c]

@hocoking123 I could be wrong, but I think it was the quake that damaged the reactors. Although a tsunami slamming into it wouldn't help. I guess being a Kiwi maybe I'm a little slanted against nuclear energy :-)

[Merecir]

@dave474c The reactors where not affected by the quake at all, they shut down automatically as planned, the cooling power was switched over to the emergency generators and everything was perfectly fine.

Then the tsunami struck and killed the emergency cooling generators...

Besides, light water uranium reactors are yesterdays technology. The future lies in LFTRs (Liquid Fluoride Thorium Reactors). Do a youtube search for that and join the revolution! =D

[davegamemaster]

@Merecir No, I think that the future lies on solar electricity, tidal, and wave power and other ones such as wind power and geothermal energy.

[Merecir]

@davegamemaster So you did not follow my recommendation to learn about LFTRs...

Solar have potential but it will never be able to provide the vast amounts of power needed in the future. Tidal and wave only provide power to coastal areas. Wind is a total failure and a scam.

Geothermal is natural nuclear power.

If you're ok with that then you should have no problem with LFTRs as they use the exact same material to generate heat: Thorium. A reactor is just far more efficient.

@Merecir First of all, its just a coincidence that that guy is also called David, but I'm another guy :D. And about what you said about tidal power etc, you should watch this video: watch?feature=player_detailpag­e&v=pxr51DrzdrE#t=268s

[davegamemaster]

@Merecir Secondly, Wind's not a scam, it generates a lot of energy. They range from 200 watts per square meter or less at 50 meters altitude to 800 to 2000 watts per square meter.

And lastly, Geothermal is not nuclear power as such, its heat, the geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface.

Gary Oak did all this in the 19th century

problem, afrika?

hey thnx 4 this video i am gonna present this video in techno fest in our college
