Desktop to Laptop. Fixed phone to mobile. Wired connectivity for the laptop to wireless connectivity through WiFi. All important steps in the untethering of people from places in the communication process.
But one wire remains. Every time we want to recharge a battery (or work for a long time in one place) we have to find a power outlet and connect with a wire. Hopefully, not for too long, if the research reported from Intel has legs.
This also has implications for the generation of clean power from the sun using satellites in orbit. Can easily be done, but the problem is getting the power down to earth. Intel’s work in close range, but may be someone else is working on the long range.
