Even we laughed a little when Google X announced Project Loon -- an ambitious experiment built to give rural areas balloon-powered Internet access -- but one year later, the company may have proven its point: this could work. Since the project was announced last June, the company has made huge strides in balloon flight time and connectivity. Wired reports that Google's latest floating hotspots have been given LTE capabilities, freeing them from the range limitations the original WiFi-based designed burdened them with. These new radios offer better transfer speeds, too -- as high as 22 MB/s to an antenna or 5 MB/s to a phone. More importantly, the balloons are staying aloft for much longer: earlier this year, one test circled the globe three times before dropping to the ground, and another has been floating for over 100 days - and it's still up there.
