Flame jet drill

Flame jet drill

The Flame Jet Drill is a type of drilling equipment whereby there is no contact with the drilling surface.

Therefore in theory, the drill never wears down.

It expels ultra heated hydrogen gas to bore away at a drill surface.

Another prototype drill called a Hydro Jet Drill is able to work in hot damp conditions.

This is a recent technology that hasn't been sold commercially yet.

The devices were featured in a "National Geographic" "MegaStructures: Deep Earth Drillers" documentary about geothermal energy. [List of National Geographic MegaStructures series. cite news|url=http://natgeotv.com.au/Programmes/EpisodeGuide.aspx?Id=674]
