WHAT DOES SCARF TECHNOLOGIES SELL?
SCARF Technologies manufactures and sells a new type of power source. This power source provides an endless small amount of continuous power that can be integrated into a number of devices. The extra power, in some cases, can keep the device constantly powered without the need to change batteries or plug the device into an electricity outlet. In other cases, it can supplement existing device power and greatly increase the duration between battery replacement or outlet recharging.
HOW DOES IT WORK?
The device that SCARF Technologies has developed is a new type of RF energy harvester, deemed the SCARF module. The SCARF modules collect a broad spectrum of radio and microwave signals, aggregate their energy, and convert this energy to a useful form.
WHY RF ENERGY HARVESTING?
Radio and microwave frequencies are ubiquitous in our everyday life. Signals with these frequencies are emitted from multiple sources, including: TV & radio towers; cellular base stations; WiFi routers; and satellite radio. Only a tiny fraction of the signals broadcast from these sources actually reach their intended targets, while the rest are dissipated in space. In a sense, this is free energy that is constantly being wasted. So SCARF Technologies decided to make good use of this free energy.
IS THIS SAFE?
The short answer is yes. While current RF energy harvesting companies rely on transmitters to broadcast signals to the power module, the SCARF module does not add any new radio or microwave radiation to the air. Unfortunately, the energy harvesters aren't perfect and do re-radiate some of these signals. However, these re-radiated signals are weaker than the initial incoming signals. So, in a way, SCARF modules can be thought of as a shield that blocks us from receiving the full brunt of the signals. Who would have thought that there would ever be a device to protect us from radio and microwave radiation and power our portable electronics?!?
