Nokia-developed Cell Phone to warn against Lightning Strikes
Scientists at Nokia have developed software that transforms a mobile phone into a signal receiver and warns the user of an approaching lightning strike.
Basically, a lightning bolt is an electric current that emits radio waves, which each bolt producing frequencies between 10 hertz and 5 gigahertz. However, the distribution of these signals depends on how far away the lightning is.
According to the scientists at Nokia, the multiple receivers in a phone, such as Bluetooth, FM, tri-band GSM, Wi-Fi and RFID, can be tuned to pick up these signals.
The newly developed software then interprets them, works out the distance to the lightning, and tells the user if the lightning strikes are getting closer.
As of now, Nokia has filed a patent (US patent application 2007/0085525) in the United States (US) for the software.

Here in Fla. one sure knows when lightening is in the area. However, when my husband walks the dog this phone might just be something that he can use. He will know if its safe to stay out for a few minutes longer. Unlike other dogs Belle could’nt care less if its thundering andlightening but my husband sure does.
