Charge your phone battery with a wind turbine

While solar cell phone chargers are currently quite diverse, they are limited to inactive at night or cloudy. Recently, Skajaquoda (USA) unveiled the Trinity mobile wind turbine - the device capable of charging the phone in all circumstances, because only a slight wind is needed.

Trinity consists of two main parts: the plastic body section with the upper and three propellers attached, with a height of 30.5cm when folded. To use it, users simply need to unscrew the 3 aluminum legs of the turbine to form a solid tripod, then set up the device in the wind.

Especially, Trinity is waterproof, so it still works well in the rain. When the rotors are rotated, they also rotate a 15-watt power generator inside. The device then converts energy into electricity to fully charge the 15,000 mAH lithium-polymer battery. At this time, users can choose one of two available USB ports at the bottom of the turbine to plug the phone charger cord or other compatible devices.

According to the manufacturer, the lithium-polymer battery when fully charged can charge 4-6 phones. If desired, users can also charge the phone directly from the generator.

Currently, Skajaquoda is planning to introduce Trinity to Kickstarter startup website. The estimated retail price for a Trinity set is $ 399, but interested people can pre-order for $ 279 and the first delivery will take place early next year.

+ Also in an effort to improve phone charging technology, a team of experts at the Korea Advanced Institute of Science and Technology (KAIST) has successfully developed a wireless remote charging device."Bipolar Coil Resonance System" (DCRS) is capable of charging 40 smartphones at the same time within a 5 meter radius.

In fact, DCRS was invented based on the idea of ​​the "Magnetic Resonance System" (CMRS) developed by Massachusetts Institute of Technology (MIT) in 2007, which takes advantage of magnetic fields to transmit energy. within 2.1 meters to the device.

The DCRS system consists of two boxes made of solid ferrite material and connected by wires. It is said to be much simpler than the CMRS but has a farther range of power transmission, up to 4.5 meters. In it, a box is responsible for creating the magnetic field and the other box produces voltage. Simply put, any device placed within a 5-meter radius between these two boxes can be charged.

The leader of the research team, Professor Chun T. Rim, said that although the equipment is quite expensive and is in the process of completion for commercialization, it is a right direction in the trend of supplying electricity in the future. .
