"Efficiency first", step by step and why can't we go 100% (Discussion thread)

[insomartin]

so what's efficiency?
http://en.wikipedia.org/wiki/Energy_conversion_efficiency
http://en.wikipedia.org/wiki/Energy_conservation
http://en.wikipedia.org/wiki/Efficiency

dahil ba boring ang word "efficiency" kaya hindi ito nagagamit sa ibang thread? wink wink! 

so let's be efficient first. before we dig deep to something over 100+ % efficient. 

puyat na ako sa isang project ko about a clock and how to make it efficient (yup mataas yung burden current nang dmm ko!) pero it's waaaaay so tipid sa kuriente. estimated ko mga 6-9 months with a 2 pcs na double AA battery. eh naandar pa din tong circuit ko.

arm, rockchip, atom's srun @ 1ghz and still has a good battery life. but not 100%

we propelled matter (hehe matter) to near light speed with 574 TeV (92.0 µJ) per nucleus and supplying the machine with a nuclear power plant to run it!
1 TeV: A trillion electronvolts, or 1.602×10−7 J, about the kinetic energy of a flying mosquito.

the question is... is it possible? are we there yet?

up!

Gusto ko pseudoscience.
Using zero-point energy to power my ultra efficient machine in order to achieve 101% efficiency.
http://en.wikipedia.org/wiki/Zero-point_energy

On topic:
A 3V coin-cell could power a PIC up to 5 years or more using low-power techniques.
An example is to run as fast as possible in shortest possible time and sleep the processor as much as possible.
Pull-ups/pull-downs could also add to standby power consumption as well as quiescent currents of your regulators.
External peripherals should be turned off as well if not used when sleeping, even the built-in peripherals too.

Does higher efficiency always mean higher profitability?

How about safety?...why the sign "Safety First" in many hazardous location facilities?

[Born2BeWired]

Marami namang thread dito ang pinauusapan efficiency ah!? over 100% efficiency pa nga ang target, how could that be boring?

Yung baliw na scientist na nagimbento ng law of conservation and entropy ang may kasalanan kung bakit di natin machieve kahit 100% efficiency man lang eh. I hate that guy!

Hintayin natin ang comment ni nukleeyus, sigurado may interesting idea din siya pagdating dito.

[toasted siopao]

Kahit machine lang na 100% efficient, makakita lang ako, ok na yan.

[Born2BeWired]

Kahit machine lang na 100% efficient, makakita lang ako, ok na yan.

Yan na nga lang major problem na eh. 
The law of entropy says 'no way' (you can't even get even - michio kaku). Basta nagconvert ka ng energy from one form to another, this law says part of it must be spent (e.g. heat) along the way.

kapag merong thread na ganito naalala ko yung sinabi ni sir motion55 na mauna pang maimbento ang warp drive kaysa yung 100% efficient na makina hehehe.pero pag na-achieve eto(minsan ang claimed overunity pa hehehe)siguro its time to replace our God Almigthy or playgod in ourselves  

[Ganda692002]

maybe close enough in real life.. superconductivity.. superconductors.. zero dc resistance.. can maintain current without applied voltage..

floating superconductors on permanent magnets.. can they be considered as machine..

[marcelino]

mismo nga yung pagkain(charging) natin nangangailangan pang energy

[rdpzycho]

tama sir they maintain current without voltage, pero they also do this with the help of a cooling agent to maintain superconductivity, commonly nitrogen.

[toasted siopao]

Kahit close enough, wala. Unless kung yung wasted na energy ay ma-iconvert mo dun sa gusto mo na output and yung waste again ng conversion na yun ay ma-iconvert mo ulit dun sa desired mo na output.

It is like creating a machine na will do a conversion of waste to your desired output, then other machines that will convert specific type of wasted energy to your desired output.

Your goal is to have a decaying wasted energy while your are boosting your output.

[toasted siopao]

tama sir they maintain current without voltage, pero they also do this with the help of a cooling agent to maintain superconductivity, commonly nitrogen.

You cooling agent absorbs the heat, therefore there is still a wasted energy.

As long as there is a waste, it means the system is not 100% efficient.

[rdpzycho]

^ tama sir. kaya sa large scale applications lang magiging above 90% efficient ang superconductor applications. 'yung laboratory experiments na nagpapalutang ng maliit na magnet, baka nasa 40% efficiency lang 'yun. few watts lang ang kailangan to make the magnet float, pero it may take kilowatts to maintain 30K (-243 C).

[Born2BeWired]

Let me correct my Michio Kaku qoute - it should be

You cannot even break even.

and not 'get even', Puro paghihiganti kasi ang nasa isip ko kanina

Ate yelo, I agree with what you mentioned. Over-unity efficiency implies that you are generating more energy than you put in. Where does that extra energy coming from? From another universe, maybe?

An over-unity machine necessarily implies that machine creates energy out of nothing. If you are able to build such machine, you are just a step away from creating matter out of nothing (Remember the famous mass energy equivalence equation E=mc^2?). Power of creation only God can have. Therefore, you are now a god!

Physicists believe the only moment something close to this happened is during the moment of creation itself- the Big Bang, where we and everything around us (the whole universe) came into being out of some quantum fluctuation that occurred in an unimaginably tiny blob of pure intense energy. The ultimate free lunch, as physicists Alan Guth called it. Even during the moment of creation, a pure energy source already sits there to seed it. Where did that pure energy came from? Nobody knows.

if there is a 100% efficient electric motor (conventional design using armature and stator), this would mean na yung counter EMF na generated nung armature windings will equal the voltage that is applied on the input of the motor and thus they will cancel each other and your motor will not run..

so this means that a 100% efficient electric motor is useless  ..

parang power supply na 100% efficient dahil di ginagamit hehehe(di nakasaksak)

nanggaling yan tita sa another universe kasi parallel universe ang ating mundong ginagalawan natin,di natin maexplain eto kasi di na natin naabot ang knowledge ng ating creator o di natin maabot ang ating creator.

['yus]

"pure energy" ? nasa ASAP sya every sunday..

parang power supply na 100% efficient dahil di ginagamit hehehe(di nakasaksak)

nangayayari din sa amin yung 100% and above na efficiency
'pag hindi maganda and/or hindi calibrated na power meters ang ginamit.
lalo na yung Voltech PM100, nung ginamit namin sa inverter, above 100% ang efficiency..

Colliding branes ba? Yan ang idea ng mga string theorists (mga disipulo ni 7 kaya mga impakta din), pero idea pa rin, nobody can figure out how to test this as yet.
