teempakguy shey u see what i was saying the other day?
STAKEHOLDERS in Akwa Ibom State have rejected the plan to site of a nuclear power plant in the state. Instead, they called on the Federal Government to partner with the state at ensuring that, the independent power plant is put to maximum use for the benefit of all.

you got that right. grin

It seems I lack proper architectural background. Despite the fact that I love the subject.
Damn, architecture is bomb men. . love that shiit and am marvelled by ancient architecture and i read them well. . . in fact ancient architecture captured my interest that was why i read more about history too

lol. . .told you to stick aroundwink

many times when i hear some people makes assertions that are supposedly scientific in the religion section, i just slap my fore-head . . .it has gone all red due to numerous of such post, there have ruined my education honestly cheesy

I'm now sticking around. I'll ask question when necessary.

Maybe using the rear earth electro magnetic power we may come up with a hypothetical concept of a hovering house wink

The architectural designs of the cities in those two pictures will greatly increase the build-up of greenhouse gases due to the burning of fossil fuels,and arable land will be used up!

disagreeing doesn't count on anything with the pace science is advancing in the past 150 years or so.

i do have the same feelings sometimes.

Ah, there we go cheesy

Now. We know in radioactivity, there are three kinds of spontaneous radiation. Of these, two are charged. We know them to be the beta particles, which are electrons, and Alpha particles. Using solid state physics, we can trap these charges. And convert them into current electricity. The main concept is not difficult. However, nature is a bitch and as such, problems and complications arise when putting a beta voltaic to practical use.

The below is a list of its problems which I found in a suite where it was suggested the tech be used to power phones.

Power produced is non-adjustable. The battery produces power at nearly constant rate (slowly decaying with time). It cannot be increased and if not consumed (or stored) the power is lost.

(Mentioned by DumpsterDoofus) low power density. 63Ni for instance produces ~5 W/kg (and kg here is just mass of radioactive material, the actual battery would be at least order of magnitude heavier). There are, of course isotopes with power densities much higher but they encounter other problems.

Semiconductor damage. If we try to increase power by using isotopes with higher decay energies we find that the high energy electrons damage semiconductors, reducing service life of batteries to times much shorter than isotope halflife. Alpha particles, especially, damage the p-n junctions, so even though (for instance) 238Pu produces 0.55 W/g of alpha radiation, it is mainly used in the thermoelectric schemes rather than in direct energy converters.

Gamma radiation. Many isotopes has gamma emission as a secondary mode of decay. Since this type of radiation is difficult to shield, this means that the selection of isotopes usable for batteries is limited only to pure beta emitters.

Bremsstrahlung. Electrons braking produces this type of radiation, that had to be shielded. Again, this limits our selection of isotopes to those with relatively low decay energies.

Low volume of production / Economics. Many isotopes cost too much to be practical in wide array of applications. This is partly explained by low volume of production and partly by production process which will be costly at all volumes because it requires energy consuming isotope separation and special facilities for working with radioactive materials. For instance, tritium (one of the materials for betavoltaics) costs about $30 000 per gram and its world annual production is 400 g (from wikipedia).

All this means, that nuclear batteries are limited to a selection of niche applications, typically those with low power / long autonomous lifetime requirements. That is not to say that there can't be innovations expanding their use or reducing costs.

[1] Tsvetkov, L. A., et al. "Possible Way To Industrial Production of Nickel-63 and the Prospects of Its Use." (2005). online version

Update. Your updated calculations on power output from 63Ni is essentially correct with one crucial distinction: 67 keV is total decay energy and approximately maximum energy of electron. But, since the decay also produces neutrino the mean energy of electron is much smaller: 17 keV (look at this NUDAT reference, or this java applet for electron spectrum). So the usable power from 1 mole of 63Ni is:
W=63Ni specific activity×17keV×63g=0.36W,
where specific activity could be, for instance, taken from Wolfram Alpha. This is not sufficient to provide iPhone peak power consumption, which is about 1.5 W (see my reason 1).

Incidentally, we come to one more reason (though not, strictly speaking, related to physics):

Safety / Regulations / Perception: 63 grams of 63Ni constitute more than 3500 curie of radioactivity, which would definitely require regulations for handling and probably would not be allowed inside a single unit for unrestricted civilian use. We know that when properly used betavoltaics are safe. But what about im-proper use / improper disposal / potential for abuse? At any rate, current perception of nuclear power by general public is not that good, so marketing nuclear batteries will present certain challenge.

My intention is to bypass these disadvantages and make the atomic battery a reality. smiley

Look at these pictures.







Yes. Scientists intend to build a bloody elevator. Stretching from the surface of the earth, and extending two thousand, three hundred miles above the earth's surface. Having a length of more than five times the radius of the earth! shocked shocked

Share your views. smiley

I don't really think it's a brilliant idea persay. But the technology required to build such can be repurposed to build other more impressive and more useful things.

LOL grin grin

It seems that the person who came up with this idea wa actually a mad scientist. His name is Konstantin Tsiolkovsky and he looks like this.

Thank you!

Well, usually, they're from Google, but there is also wikipedia and physics forums and quora.also, there are often hidden secrets in textbooks and stuff like that.

Lots of sites out there. Waiting for you to discover them. It all starts with a little curiosity. smiley

He is a mad genius i agree but yet again in the arena of scientific innovations, madness is actually a plus wink
In avatar, Avatar aang told Bumi "you are a mad genius"

If such technological wonder is achieved, no doubt it would be a great revolution to the world of space travel, it would be easier and the link gap between earth and space will be lessened a bit.

An ordinary lay man can then go to space for sight seeing and back and no doubt our children would go to space on excursions for science class project cheesy (lucky bastards grin)

i actually think its a nice idea but a very mad one at that. . .the ISS currently the most expensive man made structure will be jealous when compared to the cost this baby will worth. . .its a huge technological leap of faith which am sure gives goose bumps to those conceiving it in their minds
