Narrative:

I performed a straight in autorotation to a power recovery with my student. I reported final for runway while a cessna was taxiing on taxiway alpha. As we did the power recovery and were in a hover on the runway I took the controls from my student to see what the guy in the cessna intentions were since he never made a radio call. As I applied a small pedal input I saw that the cessna was right behind us on the runway accelerating and started to become airborne. Immediately; I applied aggressive right cyclic to the grass between taxiway alpha and the runway to avoid a collision. I tried to call him on the CTAF frequency with no response.
