US fusion startup makes history by converting plasma energy directly into electricity

​

The mechanism relies on a direct energy converter positioned at one terminus of the magnetic mirror apparatus. As moving, electrically charged particles arrive at this end of the device, the converter forces them to decelerate. This deceleration process creates an electrical potential difference, which subsequently forces a current to flow through the connected circuit.

This approach eliminates the requirement for conventional thermal systems, like steam turbines, to extract power from that specific segment of the plasma energy.
