12 volts dc wireless power transfer
Built a full wave bridge rectifier as an energy receiver. The voltage is over 12 volts dc and will run a motor for a second if I charge a cap. I need to know how to run the motor longer

Single Wire Energy Transfer & AM Radio Transmitter
Experimenter`s Corner...by Lorrie Matchett epowerplusgmail.com First Turn up your volume so you can here what is going on....This single wire energy transfer unit is capable of transmitting electricity over sixty plus feet with the use of a simple one transistor AM radio transmitter....Here is what you are seeing in this video 1 6-volt dc battery bank square black case 2 AM-Radio yellow unit 3 AM Radio Transmitter black plastic case where the red / green wires are connected, one wire going to ground and one to the receiver... 4 Energy Receiver black plastic case with dipole antenna & led light 5 Myself acting as the dipole antenna the metal antenna is optional ... The AM transistor radio is set to an off station and each time I touched the contact point on the energy receiver, it reacts as seen & heard... A Voltage Supply = 6-volts dc B Current draw on power source with receiver not connected = 7.5mA`s C Current drops to 2.8mA with receiver, led light & myself in circuit.... D Working Frequency = 430KHz

Single Wire Energy Transfer & A Human Dipole Antenna
Experimenter`s Corner..by Lorrie Matchett Single Wire Energy Transfer & A Human Dipole Antenna.... Experiment No.1 requires one high frequency 12-volt dc electronic ballast to act as the oscillator transmitter , a 11-watt CFL light bulb with the internal electronic ballast removed and 16-feet of No.18 insulated hookup wire... Experiment No.2 with No.1 requires a human dipole antenna myself allowing for the transfer of energy from the transmitter to the 30-blue led lights... Experimenting with high voltages / currents can be very dangerous, so be aware of what you are doing...Please do not perform this experiment if you are not qualified to do so...I am not giving anymore information on this experiment, what you see is what you get.... epowerplusgmail.com

Wireless electricity demo
A wireless electricity demonstration that we did as part of a freshman design project in Drexel University. We made the whole setup ourselves and also wound the coils which were made to be bifilar. The concept used for this transfer of electricity wirelessly was electromagnetic induction as well as magnetic coupled resonance If you want to contact me, my email address is cnn29drexel.edu. Feel free to ask any questions you might have. And also post any comments, these will be really appreciated.

Extending the field - with power
Wireless electricity field expansion tests. My C3198 transistor based Wensleydale tower exciter is shown here transmitting wireless power over 10ft, with the use of 1 copper wire. The wire runs from the top of the tower, to the top of a pop bottle tower. Energy transferred is strong enough to light my lightsaber 15W flourescent tube well. Power is from an old Nokia 3.7V 340mAh cell phone charger....which is shown to charge the old phone wirelessly too

Wireless Electricity Car Charging Exhibit 2011
This miniature wireless electricity car charging exhibit in which I designed and built was just demonstrated during this years engineering week of 2011...How it works...As the car gets close to the garage door, it is detected by a sensor within, turning on wireless transmitter which sends electricity to a tracking coil below the driveway. This coil tracks to the center of the car to maximize the energy transfer to the onboard receiving coil...The transmitter will stay in the on position until the battery bank of the miniature car is fully charged to a preset voltage... Indicator three windows on the garage door lights up blue when charging and off when fully charged. When the voltage is reached an infrared led located on the front end of the car transmits a beam to a detector on the garage door turning off the wireless energy transmitter...Its stays in this standby mode until needed... The green & red led lights that you see on top the miniature car are charging indicators. These led lights draw current, that is why the blue lights in the windows of the garage door is turning on & off.....They are for demonstration purposes only and can be switched off.....Note I am not giving any information on how to build such an exhibit... It`s up to you to design your own....

Tesla Wireless Power Transmission - Experiment 3
Wireless power transfer from a TX Tesla Coil to a twin RX Tesla Coil. Distance between center of both coils is 50cm. TX Coil Primary is 5 turns Secondary is 1000 turns bifilar Core diamater 12.4cm Core length only winding 435mm RX Coil Secondary primary is the same 1000 turns bifilar primary secondary is 30 turns Solid State oscillator drives primary 70V Resonance frequency is 176.5KHz max power transfer Current absorption of TX with load on RX is about 0.53A 220V 125W Load on RX coil is 60 Watt softone lamp shining much brighter than normal much overvoltage. Shunt resistor in series is 1Ohm, thick film, non inductive. Voltage peak-to-peak is 1.05V so 0.372VRMS/1Ohm * 230V = 85, 6W Input Power with load approx 120W
