Oak Ridge National Laboratory researchers demonstrated that an electrochemical sensor paired with a transmitter not only detects propane leaks within seconds, but it can also send a signal to alert emergency services.

Bruce Lester has had a lot of jobs: fisherman, horse trainer, “professional stair builder.” He last worked for a real estate company, surveying land using geographic software. “When the bottom fell out of the construction industry and the company downsized, I got laid off,”
