18 year old American girl invent a charge deity for 20 seconds to complete a cell phone charge
according to the British media in May 19th, the United States A female university student in California has attracted the attention of technology giant Google Corporation by virtue of her invented magic charger.
it is reported that Esha Hal, 18, is studying nanoscale chemistry at the Harvard University. The super fast charger she invented is actually a "supercapacitor" that can charge the same amount of electricity as a regular cell phone in 20 seconds. At the Intel international science and engineering Grand Prix held recently, Hal won $50 thousand (about 300 thousand yuan) by virtue of the invention.
Hal said in an interview: "my cell phone will always turn off because of insufficient power." It is this kind of annoyance that becomes her motive to study charging technology, and Hal, who is studying nanochemistry, applies her expertise to inventions. "Nanotechnology can greatly improve the technology in many areas, and the super fast charger I invented has adopted this technology."
besides charging time, the charging frequency of this charger is also very amazing, reaching 10 thousand times, which is 10 times the ordinary charger. In addition, Hal also hopes that the improved charger can be applied to any battery operated device such as mobile phones and automobiles. At present, Google Corporation is actively contacting Hal's technology and the two sides are hopeful to cooperate closely. According to China Daily
