Wireless electricity is one of the most emerging solutions to the global power crisis. It is defined as the transfer of wireless electricity or power from a source to a load without the use of any artificial interconnecting conductors such as wires. Wireless electricity is being used primarily on the basis that at times, wires can be inefficient (power is lost as wires transmit electricity over long distances), inconvenient (in terms of cost and labor) and sometimes hazardous (many people may be electrocuted or put in some sort of danger).

Our team paid attention to two different forms of wireless energy transfer- the first is through resonant inductive coupling, whereby energy supplied to a coil is transferred to a similar parallel coil without the use of any wires in order to provide enough electricity to light LED’s (Light Emitting Diodes). The second is through the use of a laser that reflects onto a solar panel attached to a capacitor that stores the energy converted by the solar panel, and transmits it to an LED placed at a distance. This time, the LED is connected through wires as the laser already shows the transfer of wireless energy. Other forms of wireless electricity transfer not looked at include the use of microwaves etc.

I have honestly scoured the net to find a 500uf cap that small and they simply don't exist. Where did you get yours??

Hi NerdToob.

I got mine from a store here in Pakistan. I think I remember seeing some on Ebay as well. Or maybe you could visit a home depot if you live in the US or some electronics store in your area.

Hi ! Your project proved to be very interesting! What do you mean by high efficiency coils? Is there any technical name or a rating associated with it! Also is the capacitor a variable one or fixed?WHat type of capacitor is it!

nerdtoob lbadri22 days ago

The schematic symbol shows that it is a non variable no polarized capacitor.

hey admin i have buyed copper coil 22 gaug and i am trying to run a moter pls tell me do i really need to manke circut and use 2500UF capacitor just now i am oly using loop of coil

he meant 500uf caps x2 I made the same mistake.

Your concepts are good but you have more focused on just telling about Tesla coil, and nothing about how to make it.... please add a little more description about all the componants.

I live on a farm. How could I get energy from my solar panels about 1 mile away to my home. What is the most cost efficient way.
jelte1234 333272 months ago

use a wire.

how did u know whether the coils are in resonance......are there any formulas or anything
howtowithmanish (author)  geekostate4 months ago
Both coils have the exact same design. For example the first coil is 8 by 4 inches with 35 turns. The second coil also is 8 by 4 inches with 35 turns. Hence, they resonate.

One can do this with a circular coil too with radius of 4 inches as long as the transmitting and receiving coil are of the exact same design, they should resonate and hence work :)
then why did u put those capacitors

can't this be done without an oscilloscope??
I HAVE AN IDEA HOW TO TRANSMIT ELECTRICITY BY THE METHOD OF MUTUAL INDUCTANCE I SEARCHED EVERYWHERE BUT DID NOT FIND HOW TO TRANSMIT ELECTRICITY USING DIFFERENT TYPE OF RADIATIONS
EXAMPLE:- WIFI RADIATIONS, RADIO WAVES......ETC

PLEASE UPLOAD SUCH PROJECT

THANK YOU
You mean like this?

It will be nice when the electric cars and or hybrids can just start self charging. Pull into your garage hotel parking space etc... and your car starts to utilized the wireless charger without any user interaction. A few years off true, but just like star trek items used, their ideas have created products some now consider to be neccessities in their daily lives.

Why don't you try to build a few more receiving coils with the same resonance and see what happens if you put them around transmitter coil, or in a row , one behind the other :)
howtowithmanish (author)  zabac701 year ago
Yeah that would actually help grasp the intersecting field lines theory. And those which weren't in the field lines would not light. :) Thank you for the idea.

"We have, in fact, 163 billion barrels of recoverable oil-nearly six times higher than what President Obama and the Democrats like to claim. Let’s think about 163 billion barrels for a moment: that is enough to maintain our current levels of production and replace our imports from the Persian Gulf for more than 50 years.

"But oil resources offer only a glimpse of the full picture. As I noted earlier, CRS found that America’s combined recoverable natural gas, oil, and coal endowment is the largest on Earth. It’s far larger than that of Saudi Arabia, China, and Canada combined."
howtowithmanish (author)  lloydrmc2 years ago
While patriotism is great, nationalism which hinders science is not, it is an accepted fact that oil is running out and future generations will beat a loss unless a gradual shift to greener technology occurs, we can at a maximum stretch our current lifestyle to maybe 150-200 years with natural gas etc, but the resources are non renewable and may not be affordable for all, it is foolish to think otherwise.

HI Manish,

I love how you are doing this type of research. I think there is some severe positive implications and results than can happen from it! Best of luck!

As for the claims, they are all baseless. In order to know the end of something, you have to know the total of it. That just isn't happening. Noone knows how much of any amount of minteral/substance there is in the whole world. Period. A ludicrous claim by people who want to promote an agenda.

That being said, I think Oil is a doomed tech simply because it is inefficient (I believe the number is something like 25% of actual usable power from internal combustion engines?).

People also either have forgotten, or simply not bothered to look but the first cars made were actually electric cars (re: The Electrobat).

As for ancient technology, peopel who say it never happened are the people I want to see proof they were actually there. It is a shame that people simply close their minds to possibilities. New ideas and proofs pop up all the time, disproving previously preconceived notions of 'what was'.

Manish, I look forward to seeing what else you come up with :)
Well, yes, in the early days of the "horseless carriage", all sorts of things were tried, including steam.

I believe that we ended up with the (mostly) gasoline-powered ICE simply because that is the best solution. While there is some disagreement on the exact number, a gallon of gasoline is the approximate energetic equivalent to 36,650 watt-hours. Even at the efficiency level you cite (and the attendant higher efficiency of electric motors), that is an advantage that is quite difficult to overcome.

At the present, state-of-the-art technology, it takes a $40,000 battery to take a car any appreciable distance, without being recharged in some fashion.

Yes, I know that Chevrolet Volts don't cost that much to the consumer (aside from the debate as to whether 40 miles is an "appreciable distance), one commentator added up all the upstream, government subsidies of the volt, and they amounted to $50,000 to $250,000 PER CAR, depending on production, which hasn't been much (the production line has been temporarily shut down due to lack of demand).
We ended up with ICE (petrol/diesel/LPG powered) , because of Mr Henry Ford. Before him (his car factory , with moving production line and standardized parts and production procedures) , cars were made like carriages - manually , one at the time , depending on a skill of a craftsmen and design , which made them very expensive. Therefore - great variety of different propulsion systems in early days. Mr Ford asked Mr Edison about system of propulsion(over a dinner , in some social event) - should it be electric (most of cars, or at least very significant percentage were electric in those days) and Mr Edison answered: go with petrol Henry ! (I don't have links to that anecdote , but you can Google it...)
Since than , all the efforts of car manufacturers were in the direction of ICE technology improvement , not in electrical energy storage direction (batteries or capacitors...) . There are new technologies in that field (i.e. NanoSafe - again : google) , but that isn't commercially available from various reasons (mainly - because protection of current state of order of things and relations in world).

I admit I misspoke when I said the first car used a carburetor but the first car that lead to transportation change used a means to mix fuel vapors with air, and is electric or steam. When I mention peak oil it's in the manner put forth by M King Hubbert. I believe the first sentence in the Wikipedia article sums it up concisely "Peak oil is the point in time when the maximum rate of petroleum extraction is reached, after which the rate of production enters terminal decline". I agree petroleum is a magical substance, and man will be hard put to find a replacement that matches it's portability of energy. I don't believe I ever mentioned the Chevy Volt. Of course what's an acceptable range with any vehicle will vary with the needs of the individual, but I can see the Volt meetings the needs of many. As far as subsidies the Federal government has always subsidized new trends in one way or another. I don't know where Chevrolet messed up. Last I heard when the Volt production was suspend the Nissan Leaf was selling well. Best I can tell the Volt is in effect a half-assed hybrid, and the Leaf  may be a better version of the electric car GM stopped building.
No one can't measure what they can't see or has a crystal ball that can predict future demand. However with those hindrances Hubert was able to use the data available to him to predict when peak oil would occur with US production. From here on out when peak oil will occur is going to be a moving target, and chances even those who are watching for it may not note it until we moved beyond it Actually the what is considered the first car used a carburetor, the Electrobat came along about 9 years later
'Moving target'? Is that the buzz-term people use when they want to hype up a date they can't possibly know? Wow. Delusion doesn't even begin to describe that.

Now if we're all gonna get picky, the car is attributed to being patented by Luigi De Cristoforis in 1876. The first GASOLINE Carb was done by Enrico Bernard I in 1882.

The first electric motor is attributed to Anyos Jedlik. The first electric vehicle (train) was created in 1842. The first electric two wheel cycle was displayed in 1867 World Exposition.

I am not concerned about commercial/retail. Electricity was in people's minds before gas. That is the point.
I don't get it you used everything I admitted wiyh statements in association with my statement of "moving target, to attack "moving target". No hyping at all when it is a moving target because of so many factors that will effect the time when global peak oil does come about.  Demand is unpredictable. Production projections unreliable, fortunes where lost believing production projections where reliable. So much of those projections depends on an economy that allows the public to afford the higher costs of production. Much of the projected production depends on the public's willingness to waste much more precious resources like water.  Hydraulic fracturing while being use for years with problems seems to be problematic when used with discoveries in different formations. I know you are not concerned about  what was the first that lead us to the most widespread transportation method used today. I admit I misspoke when I said the first car used a carburetor. the fact of the matter remains the first car power plant used a fuel whose vapors mixed with air  how that was achieved has to irrelevant, carburetors took over the vaporization, and then fuel injection. Conceptually it would seem steam was on everyone's mind. Anyos Jedlik certainly made a contribution to our modern life but it wasn't the automobile.

Can you explain to me what you mean by "peak oil". I have heard things about this, and I would honestly like more information about it, from your point of view. I promise that I am sincere in this.

It depends on what you mean by "car". I found this page, which I found informative: http://www.ausbcomp.com/~bbott/cars/carhist.htm

My understanding of the first Mercedes Benz (considered by some to be the first car) was that the fuel was vaporized in a externally heated tube. Thus, it didn't have anything resembling a carburetor. I admit that my recollection may be faulty.
I'm pretty sure steam engines pre-date electric ones. Are you sure the first cars were electric and not steam? Electric came before internal combustion, but external combustion (steam) most likely was first.
I found a physics professor's web site that has a fabulous page about fuel efficiency, and how an ICE works: http://www.uwgb.edu/dutchs/pseudosc/200mpgcar.htm
Agreed . Dragondon. I read in many other places where electric cars
were already invented long ago but those with hidden agenda just killed it off. we must promote renewable energy like electric . many people have come up with something practical but no financing. I do hope some rich guys out there will come in to help, eh ?
It's the nature of the free market that if someone devises a superior alternative, the financing can be had. I believe that the "invisible hand" has no hidden agenda.
