>>Dr. Harvey: Since you cited an article about hydrogen pumps, let me ask you: do they need hydrogen sensors, such as DCHT makes? How much do each of these things cost? What do they actually do - beep when there is hydrogen around? Why does anyone actually need them?<< Hydrogen burns with an almost invisible flame and is extremely explosive if the gas were to accumulate before igniting. You may have noticed that during space shuttle launches NASA has a bunch of "sparklers" going off near the engine nozzles on the launch pad. These "sparklers" are supposed to ignite any leaking hydrogen before it can accumulate rather than have the shuttle engines ignite the accumulated gas when they startup, causing an explosion on the pad. --Dennis--
