Charge Your Cell Phone with Water

Novel mobile phone chargers are on display at the Mobile World Conference in Barcelona, demonstrating innovative fixes to the growing energy requirement of our mobile devices. 

What's the Latest Development?


The World Mobile Conference, currently underway in Barcelona, is the industry's showcase for new and innovative technology. This year, a Swedish company called myFC has introduced a portable charging system for mobile phones that needs just one teaspoon of water to generate enough electricity to charge a phone. "A Californian firm, meanwhile, has launched a phone that it claims can remain charged for up to 15 years, making it the perfect spare in emergencies or disasters." Wireless charging is another staple of this year's conference. 

What's the Big Idea?

We are increasingly demanding of our mobile devices, wanting them to perform greater feats while feeling ever-more inconvenienced by having to charge them. "The difference between the energy on a phone and the energy we consume is increasing. We need to charge more often but you don't want to be hooked onto a wall," said myFC executive Bjorn Westerholm. For everyday purposes, wireless charging mats may hold great promise. Mobile devices fitted with a special case could be charged by mats located in offices, cars and restaurants.

Strange Maps
  • America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
  • Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
  • Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America

Water may be an inevitable result of the process that forms rocky planets

New research identifies an unexpected source for some of earth's water.

Surprising Science
  • A lot of Earth's water is asteroidal in origin, but some of it may come from dissolved solar nebula gas.
  • Our planet hides majority of its water inside: two oceans in the mantle and 4–5 in the core.
  • New reason to suspect that water is abundant throughout the universe.
