Sometimes I use a chimney starter. Wrap bottom with aluminium foil to cover vents on one side. Fill with lump charcoal, light, wait until fully glowing. Put blow dryer to the uncovered vents. Low speed first until the ash clears. Then up the speed and flame will jet from the top. Put on the steak, using a little grate (steal it off your range) or cast iron pan that you've preheated on the chimney or on the rangetop. Really freaking hot - probably as good as you can do at home - and fun too.

I do this for searing tuna blocks. It might be too hot for steaks that you want more than rare in the center.
