Helium Fields Forever?
Experts develop technique to locate Earth's helium reserves.
When prospectors discovered the first underground helium reserve in 1903, they deemed the gas useless because it wasn’t flammable and couldn’t be sold as
fuel. Over a century later, liquid helium is an invaluable coolant for MRI scanners, and the gas also has applications in nuclear power, deep-sea diving
and (of course) party balloons. Yet supplies on Earth are finite and unreliable because reserves have only been found accidentally during petroleum
