Products in the Marketplace


Airnergy: The Device That Charges Your Gadgets From WiFi Signals - RCA, a U.S. – based company, presented their Airnergy device at the Consumer Electronics Show (CES) taking place in Last Vegas last week. Airnergy is capable to harness useful electricity from Wi-Fi signals everywhere, and deploy it into its own battery, so you can use it later to charge any gadget that has a mini-USB connector.

Directory:M2E Power - M2E Power is emphasizing the commercial applications for their technology, with a specific goal: revolutionizing cell phone batteries. An external charger generates between 300 and 700 percent more energy than current kinetic energy technologies, and may eventually replace cell phone batteries altogether. (PESWiki Aug. 21, 2008)

Image:Parker piezoelectric generator Thumb.jpg

Fingertip Powered Charger - The working principle for these electricity generators is the piezoelectric effect. These units can be built up in laptops/cell phones and recharge your device's battery while you type.

Image:BattEQ 95x95.jpg

SmartSpark Energy Sytems - BattEQ makes rechargeable batteries last longer by shuttling charge from strong cells to weak cells in a battery string. This increases the life, performance and safety of virtually any battery chemistry including lead acid, Li-Ion, NiMh and NiCd. Laboratory and field testing has seen performance increases up to 250%.

Charging Batteries without Wires - New MIT research reveals a way to send wireless energy to mobile phones and laptops. (MIT Technology Review Nov. 15, 2006)

Image:AccelRate Battery Charger 95x95.jpg

AccelRate battery charger - AccelRate charger technology can be used with lead-acid, NiMh, NiCd, and lithium batteries. Charger utilizes a charge/discharge algorithm that enables a full state-of-charge in 80% less time than conventional technology, and will extend battery life to its original capacity because of heat reduction during charging.

Image:Motorola P970 battery charger 95x95.jpg

Battery-Powered Battery Charger - Motorola's P970 is essentially a 1700mAh rechargeable battery with a USB port on top. May prove handy for other gadgets that can recharge through their mini USB ports, such as phones, PDA and MP3 players. (Impact Lab Oct. 14, 2006)

There was an error working with the wiki: Code[1] >SunCat: Solar Batteries Powered by Sunshine - The portable power SunCat C-cells are wrapped in flexible photovoltaic panels and will slowly recharge when left to bask in the sun - just like a cat. [Remember: heat, batteries and longevity don't usually go together.] (Inhabitat Feb. 18, 2009)

Research and Development

Drawing power from the road - Engineering company Ingenieurgesellschaft Auto und Verkehr (IAV) is looking to embed roads with electrical conductors that would “refuel” the electric cars of the future while they are driving or are parked. Inductive loops buried in the roadway would generate a magnetic field to supply the cars with energy without the need for cables and connectors. (GizMag October 1, 2009)
