just gave me an idea how to weaken the greenhouse effect of methane being released from perma-frost. The idea is basically to build swarms of methane consuming quadrocopters that combust the methane into the weaker greenhouse gas CO2 (and water vapor). Something like this:
It would detect methane leaks with a
Telpos Hyper-Cam Methane. The needle could possibly be made of a light heat resistant plastic or carbon-carbon composite fibers.
Perhaps other designs are conceivable, for example a very light, gliding aircraft that simply pierces the ground, ignites the methane directly and uses the explosion for uplift.
