The thinkers at IBM tend to be optimistic when conjuring the near future. In 2006, the company released a set of prognostications for 2010 that saw widespread real-time speech translation and the use of sensors to allow for the remote monitoring of patients’ health care. Not quite yet, huh?

Now the company has released five predictions for 2015 that seem just as ambitious. My favorite one is the idea that heat from data centers can be recycled and repurposed to provide heat and air conditioning for cities, conserving energy and lowering power costs. But those holographic cell phones also seem pretty great. The following video from IBM Labs shares the quintet of innovations that may be on our doorstep.
