Jordan McCollum wrote at Marketing Pilgrim that Google is looking to partner with H3tec on their detection technology within mobile phones. She goes on to explain that there are several different applications, including tainted food and explosives.
Here's a mock-up of the device:

And forum members think it's a good idea:
Use an existing network that exists practically everywhere (mobiles) to give authorities pinpoint location of explosives. Perhaps a bit big brother ish though.
This could be interesting.

H3Tec is a fraud! Chuck Christensen lies e.g. Dear Sir, I received your email, copied below, about H3Tec’s statements about receipt of a Utah Innovation Award. H3Tec has not been a winner of a Utah Innovation Award. I will contact the company shortly to ask that they correct the references on their website. Thank you for your assistance in this matter.
