This is a work in progress based off a patent from 1987. Converts any frequency to DC given that component values are correctly adjusted. This is the fruition of my first goal when I began studying electronics. I wondered why someone hadn't modified the crystal radio to double as a passive voltage collector in standby. Using these designs and some added componentry, I believe such a goal is certainly realistic.
The power cells are supposed to be tuned LC tank circuits. Resonant with the input frequencies. Dipolar antenna is used to receive signal and transinduction is used to convert the signal into direct current.
For the crystal radio concept a dpdt switch should be used to activate standby and the signal coming off the germanium diode would be isolated with positive and negative voltages going to their respective cell banks.
This circuit, when properly configured, will sustain a DC motor, charge a 12 V battery, power a heater or run the electric on a small camper. All of these things are dependent on initial signal strength, but more importantly the values chosen to create the power cells. Design around incoming signal characteristics as well as desired output wattage rating. As the wattage will equate to available power.
For now I need to brush up on the math for resonant frequency and LC circuitry.
Energy is the breath of life, so long as there is intelligence in the universe the quest to understand and conquer this force will eternally persist. To silence the voice of one seeker is only a means of evoking the tenacity of another.
