Automated voltage regulation (AVR): Also known as line-interactive topology, this can be a much more Sophisticated type of electrical power management that uses a small transformer like a buffer to compensate for energy dips and surges without relying on the battery.

What is it about steel propellant that can offer a "magnitude improvement in thrust, using a magnitude reduction in quantity and mass”?
We really have only just one downside of Take note for this unit: its useful content superior price.
