"How many BTUs do they generate?" he relents, head tilted and eyes squinted in mild curiosity. "What would be the limitations on converting them to mobile power generators?

He tilts his head back again, gaze on the middle distance as his mind kicks more fully into gear. "Where are you at with forcefields?"

Not necessarily something powerful enough to stop weapons, but a mobile means of providing protection from the weather? That could help a lot of people.
