Where X equals…
The 50 Years Anniversary of Victory is a Russian nuclear powered icebreaking ship, the largest icebreaker in the world.
The Tupolev-119 was a modified Tupolev-95 bomber with two regular engines and two experimental engines powered by a nuclear reactor in the bomb bay. The bulge created by the enlarged fuselage is clearly visible in the photograph above.
Because pacemakers require surgery to implant it’s a good idea to make the batteries last a long time. The Medtronic 9000 was powered by a radioisotope thermoelectric generator that used a tiny plutonium-238 source and at least one nuclear powered pacemaker is still running 34 years later.
