A real lava flow has very mottled appearance with 1000s of dark spots on the surface and lumpy flows instead of a smooth column. Lava also has a large Poisson's Ratio so the flow will be very tapered from the point of fall. .
Yes, I bet it could generate steam to keep a pretty large power plant running.The amount of energy contained in that stream is mind boggling.
That's for lava that's exposed to air as it flows.A real lava flow has very mottled appearance with 1000s of dark spots on the surface and lumpy flows instead of a smooth column.
