Fusion rocket engines speed trip to Mars

The video explains a fusion rocket that could transport a crew to Mars in 30 to 90 days. The rocket pulses once per minute, expelling exhaust at 30 km/s. Solar energy charges capacitors to power the rocket's magnets. Each pulse crushes lithium rings around plasma, creating thrust. The rocket is active for 10% of the trip, half for acceleration and half for deceleration. Unlike chemical rockets, the fusion rocket's fuel is only 50% of its mass, compared to 98% for a Saturn V.
