IBM predicts a sci-fi future sooner than you think.
According to Bloomberg, IBM says mobile will be able to project a 3-D image of callers using batteries powered by kinetic energy.
The predictions come from the computer firm's Almaden research centre in San Jose, California.
Other forecasts include computer programs that can tell when and where traffic jams will take place, environmental information generated by sensors in cars and phones, and cities powered by the heat thrown off by computer servers.
IBM invested $5.8 billion in research and development last year, 6.1 per cent of revenue.
At Almaden, scientists have researched nn electric car battery that runs 500 miles on one charge, a filtration system for desalination and a program that shows changes in geographic data.
Maybe they could get phones to get 3G connectivity in London at rush hour.
Perhaps in 3015.
