The conclusion is simple. There is no point to invest a broken penny into this power station.

Homework Statement Effective Power generation of the plant is 5.43*10^{7}W but it will required 9*10^{16}J to be created. Essentially the break-even will after solving equation Energy required/Power Generated however I get results of almost 50 years. Would this be correct...

Hello, I'm a very curious EPE student (electrical power engineer) who is trying to figure out why there are variable gaps between joints of large steel structures. Because of this gap the stress seems to be distributed with peak force at the intersection of the bottom plate, why is this...

Thanks, I was right :cool:

Hello, I just came across this question and no answer could be find, my best assumption is that kitchen foil is simply 'holding' into positveley charged materials? Thanks, JJ

Super simple, thanks.

Hello, I can't figure out what's the difference between the two: Gain - how much the amplitude of the signal was increased/decreased Amplification - how much the amplitude of the signal was increased/decreased If we take a basic inverting amplifier circuit: http://alturl.com/39n78 We...

Very basic one which I used long time ago (but it's good to start with) is: flastad.com/circuit (free) More advanced toy is: pspice (9.1) - http://www.engr.uky.edu/~cathey/pspice061301.html which is also free. I would recommend to start with pspice, find a few tutorials and you will be fine.

"what's the difference between electrical and electronic engineering" - that's the only question I was asked.

Hi, I'm currently in a dead spot of my mini-project where I've to decide upon the coil shape. I can't find adequate definition of both coils by the means of: - size - losses - frequency range - inductance - skin depth which makes it impossible to argue which one would be better...

Pretty much answered by jtbell.

#1 I've tried to remove the account but looks like it's impossible? Does Data Protection Act 1998 doesn't supposed to work everywhere? #2 is it also impossible to change my nickname?

This is the final correct solution. Thanks, thread can be now closed.

All right, thank you very much. I will use the very first formula, still it isn't exact 2.5msec.
