Mikhail Vaga, a 19-year-old student in Minsk, Belarus showed off his invention – a power bank which uses the gyroscope and human kinetic energy to charge electronic devices.
Vaga explained the science behind his gadget.
Setting up a crowdfunding campaign on Kickstarter, to receive backing for his innovative idea, saw his project gain over $50,000 (€42,317) in two weeks.
The backers already received the powerbanks from the first production run, for $79 (€66.8) a piece, and Vaga is now preparing for mass-production.
