Nerdy stuff but its all good Nerdy stuff but its all good.

Catlanta: Nulear fusion? really! what movie did u just watch? In Nigeria? smh

wat is "SMH" ?

I BELIEVE THIS

So this is where all the nairalandnerds have been hiding..cool stuff.

The beauty of science

SimonAndal: Nuclear fusion takes 4 H atoms and combines them to make 1 He atom. In the process, only 0.7% of the initial mass is converted into energy in accordance with e=mc^2. Fusion doesn't convert all mass to energy, only a small fraction. This site mentions the 0.7%:
http://en.wikipedia.org/wiki/Nuclear_fusion

This site is far more interesting.
We can calculate the 0.7%:

From Answer 1, the masses involved in a single reaction are: initial: 4 x 1.673x10^(-27)kg = 6.692x10^(-27)kg
final: 1 x 6.645x10^(-27)kg
mass lost (converted): 6.692x10^(-27)kg - 6.645x10^
(-27)kg = 0.047x10^(-27)kg
percent lost: 0.047 / 6.692 x 100% = 0.702%
The above site also calculates the energy released from one reaction as: 4.3 x 10^(-12)J/reaction
Let's calculate: Assume the water consists of pure H2O. Assume further that it will be it will be separated into H & O. Ignore the energy involved in this
separation (it's minor). Assume all of the H (hydrogen) will be used in the fusion process.

How full is your glass of water?
Assume 8 fluid oz. There are about 29.57g/oz of water.
Mass of water in glass = 8 oz x 29.57g/oz = 76.56g
Number of water (H2O) molecules in the glass:
76.56g / (18.051g/mol) x 6.0221415×10^23 molecules/
mol
= 2.544x10^24 molecules H2O.Each molecule of water (H2O) has 2 hydrogen atoms. Number of hydrogen atoms in
the water: = 2.544x10^24 x 2 = 5.108x10^24molecules H
Four hydrogen atoms are used in each reaction. Number of reactions possible: 5.108x10^24molecules /4molecules/reaction = 1.277x10^24 reactions
Energy released: E = 1.277x10^24reactions x
4.3x10^(-12)J/reaction= 5.491x10^12 J
There are 3600000J per kWh. Energy released in terms of kWh: E = 5.491x10^12J / (3.6x10^6J/
kWh) = 1.524x10^6 kWh
Rounding the results, and converting to MWh and TWh:
E = 1500000kWh = 1500MWh = 1.5TWh
The 8 oz glass of water has about 1.5 Terra-Watthours (TWh) potential fusion energy.

To put this in perspective, the entire USA used about 4000 TWh in year 2010. That glass of water
would power: 1.524/4000 x 100% = 0.04% of the USA's need for 1 year. Or viewed another way, the number of glasses of water that it would take to power the USA
for one year is: 4000/1.524 = 2600 glasses (rounded)

There are over 2600 cities in the USA, so on the average, a glass of water would power more than 1 city. Note that there are extreme difficulties containing a fusion reaction. It is not technically
feasible yet, but scientists are working on that problem.

JAGBAJANTIS

Run with it.
God didn't make the whole world 70% water for no reason.
The person meant to bring that breakthrough into the world is either still sleeping, getting there, or still chasing silly girls around town
If figured out, water, along with solar could be the best renewable energy source on earth.

Bro let we here in nigeria just forget about this nuclear fusion stuff, we have excess water, excess gas then what stop us from producing electricity? Nigeria cant even generate electricity with nuclear reactor not to talk about the nuclear fusion unless u want to wipe out the entire country. This country need serious resolution without it nothing will change.

I was about to get some rest before I saw this so let me help a little bit. Nuclear fusion is a feasible/possible but extra-ordinarily difficult process of generating usable energy. its different from nuclear fission where you can enrich Uranium to a chain reaction sustainable enrichment %( I think about 3% or there about). Someone used the word "bombard Hydrogen." Well, in fusion the word bombard does not apply rather we compress the hydrogens to a critical temperature where the 4 hydrogens (one proton each) fuses into one Helium (atomic number 2, mass number 4). difference in mass * c^2 becomes our energy yield. This theory sounds great but in practice its close to impossible. the only time men did fusion was during hydrogen bomb explosion and even in that about 4 nukes were used to funnel the hydrogen into a tight small space where the energy released by the nukes did the compression before fusion occurred. So in a nutshell, dont even think of fusion in Nigeria yet. PHCN is going to be king for a very very long long long long timeeeee, Lol!

I suggest people go pay their electric bills 'cause even the best phycists haven't figured out the best way out (the only consolation now is that USA, Korea, UK, France, I think Brazil is part of it too, are working together in France for a sustainable fusion chain reaction). Its still a long way but there is hope.

Nuclear Fusion? Isn't that a Russian concept? Besides such a power source will be a political bargaining chip.
Wind, solar, and geothermal are yet to be maximized if explored.

The problem has always been how to harness that energy

shey una no want make i drink water again? lol

Energy released: E = 1.277x10^24reactions x
4.3x10^(-12)J/reaction= 5.491x10^12 J

kWh) = 1.524x10^6 kWh
Rounding the results, and converting to MWh and TWh:
E = 1500000kWh = 1500MWh = 1.5TWh
The 8 oz glass of water has about 1.5 Terra-Watthours (TWh) potential fusion energy.

To put this in perspective, the entire USA used about 4000 TWh in year 2010. That glass of water
would power: 1.524/4000 x 100% = 0.04% of the USA's need for 1 year. Or viewed another way, the number of glasses of water that it would take to power the USA
for one year is: 4000/1.524 = 2600 glasses (rounded)

There are over 2600 cities in the USA, so on the average, a glass of water would power more than 1 city. Note that there are extreme difficulties containing a fusion reaction. It is not technically

Is it FEASIBLE?

All this is good but we I still don't see how you can initiate the process without you blowing up the whole effing world

yeah why it is not feasible is because the heavy water tritium and deuterium needs a gargantuan temperature of about 15 million degree celcius that which is been provided in the sun and stars. It is also feasible in the sense that this high temp can be provided through fission e.g pitheblend, but this reaction would not be controllable and so can cause massive destructure

virgo: @Op Can you break it down in layman's terms? Not all of us are conversant with scientific language.

go n enroll in science class , sorry no simpler terms for dis

jes 1 observation.....i think the amount of energy u calculated had a lil mistake,1500MWh=1.5GWh not TWh.........so maybe we might need abt 1000 glasses of water

Fusion requires a great deal of heat,this heat cant be contained by any material,the only place where fusion occurs is the core of the Sun not even its surface....fusion on earth :/

Nice theory

We have two problems.
Controlling
tapping.

Obviously, if we tapped just 0.7 percent, the 99.3 percent remaining will form an energy excess that can take out a city.

noxide:
Nuclear fusion will be possible. It's only a matter of time

the problem is, can we live to see that time?
