Is this feasible?
If so how can I go about building it.
QuoteIs this feasible?It doesn't seem likely.
There is a problem with radio waves: If you use only a coil, you get a lot of everything, but the result is almost nothing.
Tentzeris says exploiting a range of electromagnetic bands increases the dependability of energy scavenging devices as if one frequency range fades due to variations in usage, other frequencies can be used to pick up the slack.The team is also looking at combining the energy scavenging technology with supercapacitors and cycled operation so that the energy builds up in a battery-like superconductor and is utilized once the required level is reached. The team expects this approach would be able to power devices requiring over 50 milliwatts.
