Wireless Electricity

if we can find a way to induce electron flow independent of any power source (battery, outlet power), then we have something better than wireless power. we have power on demand.

by "find a way to induce electron flow" what you're saying boss is to make an "electrical potential difference" or commonly called Voltage..this is the only way in order to make as you call it "electrons flow"..regardless of whatever application you're using.. simple example is battery.. and the only way to do that is to have a power source to generate "electrical potential difference"..

let me cite two examples used above:
1. solar cells:
->as i've mentioned, to generate electricity we need to have "electrical potential difference"..solar cells do that by "photovoltaic effect"..when photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon, electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. Due to the special composition of solar cells, the electrons are only allowed to move in a single direction. Complementary positive charges, called holes, are also created and flow in the opposite direction to the electrons. This is what creates the "electrical potential difference", since all the "electrons" (negatively charged) are on one side, while the "holes" (positively charged) are on the other side..in effect, making an effective DC power source..
2. human body
->to simplify matters, think of our body as rechargeable battery..the "electrical potential difference" is made by the imbalance between potassium and sodium ions inside and outside the cell. This is basically a type of electro-chemical power source (i.e., battery)..
->for details, pls refer HowStuffWorks "How does the body make electricity -- and how does it use it?"

thus, we can't induce "electron flow" without power source (electrical potential difference or voltage)..it simply cannot be done..
maybe what you've meant boss is that we have to have better alternative power sources like wind, solar, tidal, fuel cells, etc..and something which we could fit in our pocket or in our cars..the technology is already under development, with some already in prototype stage..
thanks..

unsa ba jud, could it really be possible?

[moklo]

maybe if that type of source of energy is fully harnessed, then mochange nasad cguro ang electrical designs sa mga electronics nato?

Sakto jud ka bro, kinahanglan cguro ma less pa jud ang power consumption sa ato mga appliances kay aron ma gamit ani nga technology.

botom line ? technology kills?

nya ang pina ka bottom pa jud kay technology kills mother earth. this is why we have global warming, daghan na kaau manga calamities... etc....

@gaevwa: that's exactly the problem. a lot of people are like you and are still stuck in that particular mindset of electron flow. there are actually other ways of inducing electron flow. one particularly interesting way is through vibrations which could be the basis for wireless "power".

my point is that too many people are stuck in a "science proves everything" mindset, ignoring the fact that a majority of science comes from observations. science is, in fact just informed guesses. thinking that science is the be all and end all of knowledge is a big mistake a lot of people make.

@john_yo: you shouldn't make generalizations that are too easy. you ought to think it through first. and your so called "mother earth" is not the one getting "destroyed". it is humanity that is killed. we could reduce our cities into nuclear wastelands and the earth will still go on. we could all die off and we would matter less than a proverbial eye blink to the earth.

people who would have you believe that you are actually "saving mother earth" are doing you no favors. don't follow their arrogance. it's not saving "mother earth". it's saving yourself.

ok..i'm open to any new ideas...can you explain to me unsaon ni?

i'll just update my post nalang:

Sa pagkatinuod lang bai..nalibog jud ko sa pasabot nimo..and you even told me that people like me is the problem since were "stuck" on some particular mindset of electron flow? asa ato pasabot nimo, kadto "no power source"? or kadto "wireless energy"?

If ang "no power source", Ok..let me ask..the vibrations you've mentioned which would in turn produce electron flow..is it not a technically a "power source"?

I wasn't actually arguing on how to make electricity..i'm just pointing out that making electricity is actually what a power source is all about..regardless of what kind of electron physics (electromagnetism, atomic theory, coulomb's law, quantum, Electrostatic, triboelectric effect, etc.) were discussing, if we want it to be utilized into electricity, then we have to call it as "power source"..

Basic closed circuit diagram: (DC and AC)

E- stands for Electrical Potential Difference (Voltage), thus the power source..
I- current
R- resistance (or the load)

One concept of using"vibrations" and other kinetic energy as you've mentioned is through the use of crystals and some other materials exhibiting piezoelectricity..this is what they are using at experimental dance floor power source, sound powered cellphones (charges your phone while talking), or even typing powered cellphones also..best common example is the new cigarette lighter nowadays.. the spark that you see is an example of breakdown of high voltage field..

Now, let me quote Britannica (through Answers.com: Wiki Q&A combined with free online dictionary, thesaurus, and encyclopedias) on case of piezoelectricity..the mechanical pressure (through vibrations) exerted on some non-conducting crystals polarizes them, by slightly separating the centers of positive and negative charge. The resultant electric field is detectable as voltage. Thus, a power source gihapon..
->piezoelectricity: Definition from Answers.com
Piezoelectricity - Wikipedia, the free encyclopedia

sample product:
Kinetic energy powered Kyocera cellphone

but if you're referring to "wireless energy", wala man siguro ko'y gi-post diria nga nag-oppose ani?

let's try lightning. This is a "wireless power" source. There was an attempt to harvest it..and was able to succesfully light a 60W bulb for 20minutes from a small flash in a modified lightning rod..but still the term applies. It's a "power source"..

Regardless of whatever you mean, you cannot do away with 4 important terms: voltage, current, resistance and power..and by saying "voltage", that will always come with a power source..even the "vibrations" you've mentioned will produce the electrical field.. even if we use magnetic fields, you will always end up with same four terms.. and you'll always end up with the term: "power source"..

possible ba ni? karon pko kadungog ani dah

[pepau]

very possible. pero dili tag as nga rating. think of the rfids nga gigamit sa mga call centers. where do you think their id's(with the chip inside) get its power to transmit the data to its reciever..

Indeed very much possible.

There are generally three types of RFID tags: active RFID tags, which contain a battery and can transmit signals autonomously, passive RFID tags, which have no battery and require an external source to provoke signal transmission, and battery assisted passive (BAP) which require an external source to wake up but have significant higher forward link capability providing great read range.

sa passive and BAP RFID, morag mas nindot to ang explanation sa post ni Comcam.

So possible with low Volt - make one yourself
