Holographic 3D phone calls and batteries powered by air could become a reality by 2015, according to IBM.
The company predicted the changes in an annual survey, asking 3,000 researchers to name five ideas that are expected to become a reality in the next five years, Bloomberg reports.
This year, mobile phones able to project holographic images topped the list of predictions.
The other ideas mooted by the scientists were batteries powered by air, software that predicts when and where traffic jams will occur, sensors on cars and mobile phones that give environmental information and cities powered the heat generated by computers.
"New technologies, such as novel on-chip water-cooling systems developed by IBM, the thermal energy from a cluster of computer processors can be efficiently recycled to provide hot water for an office or houses,” IBM said.
