Considering that most wireless devices need to be powered, it makes sense to invest in an emerging technology that provides wireless power. I could see many applications: cellphone/tablet/car charging on major highways (for a fee of course). Perhaps, in the conference rooms at companies and universities/colleges there would be power available for those in attendance. Some interesting possibilities to think about..
Moving towards energy industry seems very ambitious. A very long term plan is necessary so I have excited to see the commitment from Qualcomm. This company is moving so fast! From a small company selling IP, to a chip vendor and now moving towards a whole new system level in another industry. Good luck!
