nPower Personal Energy Generator
US energy start-up Tremont Electric has developed the nPower PEG (Personal Energy Generator) – a device that gathers and applies a consumer’s kinetic energy (created by physical movement) to power more than 3,000 types of handheld devices.
When placed upright in a bag or purse, the PEG – a 10.5-inch-long cylinder – begins collecting user-generated kinetic energy. The amount of charge the PEG can supply to handheld electronics depends on the power demands of the device. An iPod Nano needs the equivalent of about one minute of energy generated by walking to power one minute of audio playback. However, a smartphone may require the equivalent of nearly 25 minutes of kinetic energy for one minute of calling time.
Plugging a portable mechanism into the nPower PEG can also help conserve and prolong its existing battery charge. The device, which retails for around $200, gives more freedom and security to consumers who engage in traditionally tech-averse activities, such as camping and long-distance hiking.
