T3 writes a company called Nethercomm is working on broadband Internet through natural gas pipelines:
The crazy-sounding concept is still just that - a concept - but a company called Nethercomm claims it will be able to deliver a Terabit wireless link over the last mile of current broadband networks by "beaming" signals down gas pipes. It calls the service "broadband in gas" or "BIG" for short.
Because the gas pipelines are isolated, there won't be any trouble with interference from other wireless sources - and the only piece of equipment required is a $200 receiver box on your gas meter. Amazingly, Nethercomm claims that its service would deliver speeds of up to 6Gbps to the home - meaning you could download huge files in the time it takes somebody to say, "can anyone else smell broadband?"
