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.

1).can u tell me that what is the efficiency of this project.?
its look like the distance b/w ur primary and secoundry coil is just 3cm, its not so efficient .

how much power is loss during transmission?

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.

use a wire.

That's not very efficient. I don't think 2 miles of wire would be cheap either. You'd have such a voltage drop there would be nothing left. Why not just put some solar panels on your home?

In comparison, it will definitely be. I don't know what sort of wire would be most cost-efficient though.

the voltage drop would be less of a problem the higher the voltage is, so try to get the highest voltage possible. (and possibly down transforming it later on again) this is the same reason the powerlines have several thousands of volts.

"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."

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 :)
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.

It was my understanding that the first internal combustion cars used a simple form of fuel injection, and that the carburetor (a hodge podge of several systems, to handle idling, acceleration, decelleratiion, etc - instead of ONE device that does the job right in the first place) was invented later.

Then again seed oils were used a fuel before gasoline/petrol back then too. Often the choice was hemp oil, because every farmer grew hemp (without all that hemp to make sails and ropes, the navies of the world - including all trade - would have disappeared, and that includes the merchant fleet that made the US rich on the triangle of "slavery, sugar and rum").

"first electric motor" -

Well now, that depends on what KIND of electric motor you mean. Early electro static motors were made by the Monk Andrew Gordon in the 1740s (not useful). Faraday had a simple mercury motor in 1821 (again not useful - it was the first conversion of electrical energy into mechanical energy using electromagnetism). This was refined into Barlow's Wheel (Peter Barlow,1822 - again using mercury) and it was the first device made to rotate using electricity.

Anyos Jedick had the first DC motor with electromagnetic coils in 1827 (with all its basic pieces - stator, rotor, commutator) but it was not usable for anything in that model - it is a 'proof of concept' model that looks like a roughly made toy.

However it was Moritz Jacobi who made the first DC motor with any real output (1834). Sturgeon made the first DC motor that could run equipment in 1932.
US Inventor Davenport created and patented the first direct-current
electric motor made with the intention of commercial use (1837).

But is was Jacobi (again) who made a better motor in 1838 than his first one was - good enough to run a boat and move people across a river. However none of these were commercially successful until

Then in an odd turn of events, in 1871, Zenobe Gramme made a new version of the of the dynamo (the anchor ring dynamo) which removed some problems, and then he used one of them to create energy, used to TURN another one - and IT became the first VIABLE commercial motor.

.As for electric cars -

The one that Anyos Jedick made in 1828 was a tiny model (not one you could drive in), and so was the one made in 1934 by Thomas Davenport.

In 1835, Professor Sibrandus Stratingh (the Netherlands) & his assistant Christopher Becker created a small-scale electrical car, powered by non-rechargeable primary cells, but not useful yet.

Trouble was there were no rechargeable batteries yet - not until Plante invented the lead-acid battery in 1869.

*** BUT ***

The inventions that gave us seriously useful electricity (not just Faraday's laws) came from Tesla and AC electricity (the patents are his - indisputably), but he made the mistake of working with people who stole from him. Edison stole his AC electrical generation systems, and then Tesla got screwed again when his temporary assistant Marconi stole radio from him. Mind you, Marconi was claiming to have invented radio, at a time when Tesla had a simple remote control boat that use radio.

Then again, Edison was a lot like Bill Gates - big on marketing, big on ego... after as much cash as he could get, and no ethics to speak of. Mostly he was very talented at convincing intelligent/talented people to work for him under contracts that said HE owned everything they made... and keeping their work for his own profit. He was also very good at stealing other peoples inventions outright and getting away with it.

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:

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.
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.
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:
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.

Wow that actually means a lot. :) Thanks Follow me and you'll stay entertained. My next project will be on be a detective, fingerprint and footprint analysis so stay tuned :)
"Accepted fact"? It is nothing of the sort, and how is this nationalism? The report cited actually attempted to enumerate worldwide reserves.
howtowithmanish (author)  lloydrmc3 years ago
USA might have 163 billion barrels of oil remaining but that is numbered. Therefore the amount 163. Why can't they say infinity. Because It WILL run out someday or another. That should be accepted. And due to the current speed of technological advancements, burden on these resources is increasing.
Interesting point about the "burden on these resources", as the advancement in technology also encompasses exploration for, extraction and production of fossil fuels.

The post I read noted that we have had somewhere on the order of 22 Billion barrels of proven reserves since the 1940s. As technology advances, so does the recoverable supply. As prices increase, so does the feasibility of extracting more and more reserves.

No, the supply is not infinite. And, believe it or not, I wholeheartedly support any privately funded idea as to what we can do and how, once the economics of fossil fuels play out.

For instance, Wikipedia has a splendid page about growing algae and processing to use where fossil fuels are now - I even learned a few things there. I noticed that one effort is being partially funded by Boeing. Yes, despite what one commentator might comment, it is possible to fuel an airliner with renewable fuels. It has even been done, on an experimental basis, more than once.

I believe that this instructable is the very essence of what this site is supposed to be about: come up with an idea, experiment with it, publish your results (along with some ideas for improvement), and discuss in an open forum, with mutual respect.

I believe that commenters here have all adhered to the "be nice" policy, even pointing out what they see as errors and shortcomings in a polite fashion.

Unfortunately, I am currently in a pitched battle in the comments section of another instructable ( ) with a couple of people whom, IMNSHO, *don't* get what all of this is about, and are attempting to stifle any and all discussion that runs counter to their orthodoxy. Sadly, I admit that - in the face of unrelenting attacks - my own comments have devolved to the point that I'm not complying with the "be nice" policy as well as I would rather.

At any rate, please keep up your experimentation, and please keep posting instructables. It is young people like you that give me hope for our future.

My physics teacher in school yelled out the word "Sir" every time a student would solve a question correctly. It was his way of showing respect. And today I yell out to you "Sirrrrrrr" Respect. Cheers

Thank You, young man, for such high praise as to be compared with a teacher that you seem to admire.

It means a great deal to me.

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.

If the coils were in the road, the cars could charge while they drive... forever.

What sort of copyright issues will I have to deal with if I intend to publish a paper or exhibit this device? Your group has retained the name... 'Wi-Ticity"... did u have to?

Does anyone else have an idea about this?

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

howtowithmanish (author)  nerdtoob1 year ago

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!

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
