Theoretical arguments establish that the electron temperature to ion temperature ratio in the hot plasma is likely to be close to unity. This implies that a hot ion component (ion temperature, approximately 40 x 10 to the 6th K) is also present. It is pointed out that under these conditions, heat flux limitations by electrostatic turbulence is ineffective. A reduction of the heat flux, however, is still possible in response to the breakdown of classical theory. It is shown that only nonclassical current dissipation processes can sustain a hot source against cooling by a saturated heat flux. An investigation of collisionality as a function of position along a magnetic loop reveals that the breakdown of classical theory should be expected to occur first near the base of the loop. It is concluded that the newly discovered hot source is important for the energy budget of the flare, even if the heat losses are considerably reduced. It is estimated that for the flare of May 21, 1980, a total of about 10 to the 31st erg was necessary to maintain the hot source against heat losses over the period (about 10 min) that it was observed.
