2024-02-27 MOSFET Driver
The gate driver circuit shown in the screenshot uses BC547s, which are limited to less than 200 mA current. Instead, if the two transistors were BC337 or PN2222A which can easily handle over 500 mA, they could charge and discharge the gate faster, and thus reduce the dissipation in the MOSFET.

There is one issue that all nuclear plants have and that Sabine didn’t address, and that’s the huge consumption of water that all thermal plants have. Building nuclear or any thermal plants near a source of coolant water is necessary, and that can become a major conflict when most populated areas are also near water.
