555 crazy induction heater idea.?

Hey guys, just wondering, and looking around, would it be possible, to make an induction heater using a 555 timer? I built a circuit online using falstad's circuit creator, and it seems to work relatively well. What would be the limitations of this circuit? Here's the circuit itself actually.

The transformer on the circuit ups the voltage from the 555 timer so that you can use higher voltage on the mosfet. The op amp is there to increase current, and to invert the signal from the 555 timer so that it comes out normally from the transformer.

Would this work correctly?

Or, moreover, what more improvements could i make to it so that it would work better?

Update:

...i know that it cant be higher than the source, its just an example of how to keep it in the +20 - 20 voltage safety range for the fet.

    You blow the MOS-FET right away if it really has 224.8V on the Gate. And it is impossible to have GATE voltage higher than the Source value. It is a failure design.

    there is no autotune (length over time) or no control.
