Student accelerates battery charging smartphones
A young American student won a competition supported by Intel with a device to charge a smartphone in less than 30 seconds.
It is a repetitive daily exercise: plug your phone for a few hours to recharge the battery. A student of 18 years old may have found a solution to go faster. Eesha Khare, Saratoga, in California has won the purse of 50 000 dollars Contest International Science and Engineering Fair Intel.
She presented a device named "supercapacitor" capable of charging a smartphone in less than 30 seconds. This very small device that can fit into a mobile phone, allows up to 10000 load cycles, whereas conventional batteries generally accept 1000 cycles. Apple, for example, guarantees 80% of the original capacity of the battery of an iPhone after 400 full charge cycles. To do this, the student worked on nanochemistry and storage of energy in a small volume.
About its speed, manufacturers are also interested in the flexibility of the small charger Eesha Khare. This would make an ideal component for future devices that will equip our wrists (watches connected) our eyes with Google Glass. The Mountain View company has already contacted the young student about his invention. Another focus of his invention could be the electric car like the Tesla.
Other academics have been rewarded as Henry Lin Wanjune Shrevesport in Louisiana for his work on mapping data of the cosmos. A 19 year old Romanian Ionut Alexandru Budisteanu, won the Gordon E.Moore detection solution for its streets and sidewalks for autonomous cars less than 4000 dollars.
