On the run up to the Second World War, there was an amount of anxiety in Britain about the Germans having a potential technological edge over the British, much as they had had in the First World War initially with the use of zeppelins and bomber aircraft.
The solution to this, in the 1930s at least, was the British Air Ministry offering a £1000 prize for anyone that could invent an energy projection weapon that could kill a sheep at 100 paces.
Now, despite English inventor/crank Harry Grindell Matthews (main image) claiming to have invented a death ray that could ignite gunpowder and "incapacitate" enemy troops from four miles away all the way back in 1923, he ended up not presenting anything useful for the competition.
Instead a pair from the Radio Research Station, Robert Watson Watt and Skip Wilkins (after concluding that it would require too much energy to actually create a death ray that works like they do in science fiction) were inspired to create radar instead, which both gave the British an edge over German bomber planes once the technology was perfected in the 1940s and actually had peaceful applications , such as with civilian passenger aircraft.
Perhaps unsurprisingly, both the Germans and the Japanese were also experimenting with death rays of their own, with the Japanese allegedly being the most successful with their experiments with directed microwave weaponry. The Ku-Go, as it was supposedly called, was ultimately not created (obviously) by the end of the war, but it did reportedly make a lot of rabbits, mice and such very unhappy.
