[MCU] How do people stand near Tony Stark without being baked alive?

The arc reactor in his chest produces three gigawatts of power. That's around a million times more than what an oven uses, which means that at a thousand times the distance the power would be the same. But lots of people have stood within a kilometer of Tony Stark with no ill effects. For example: Tony Stark.

Because he's not radiating that energy out the same way an oven does. Either the arc reactor isn't pumping out 3 gigawatts every second, and instead only outputs what the devices attached to it are drawing at any given moment, or he has some way of storing the energy for future use without much waste heat.
