This is really interesting, take a look:
That is a great use of Google Glass for helping to save the lives of paragliders. No one would want to be fried by power lines! This is a really great use of science and technology to protect paragliders from death-dealing occurrences with high power lines.
Apparently deaths by this accident do not need to be reported so statistics are really not known on how often this occurs.
Clearly, rescuing a person hanging from power lines is no easy task and requires highly specialized rescue personnel who are not always likely to be available everywhere.
Great inventive use of technology for helping others.
