A Spanish engineer and aeronautical pioneer, Juan de la Cierva, developed the original “autogiro”. Its name was derived from the self stabilization accomplished by a four-bladed horizontal screw turned by wind produced in the sky. In addition to the nam…
The invention of individual diving suits in the early 18th century allowed a more refined exploration of the ocean depths. The initial drive for the creation of diving suits was to aid salvage missions, at a time when many ships (carrying many treasures) w…
The R100 airship was built as part of a British government programme to develop airships to provide passenger and mail transport between Britain and the countries of the British Empire, including India, Australia and Canada. Originally, it was proposed tha…
Early electric cars found a lucrative market for driving around cities. Rechargeable batteries that provided a viable means for storing electricity on board a vehicle did not come into being until 1859, with the invention of the lead–acid battery by French…

Until the atomic bomb could be tested, doubt would remain about its effectiveness. The world had never seen a nuclear explosion before, and estimates varied widely on how much energy would be released. Some scientists at Los Alamos continued privately to h…
In 1973, the US Army started testing possible designs for an anti-tank grenade. Commanders in Europe had asked for some sort of ordnance for destroying tanks in close quarters. If Warsaw Pact troops had invaded, NATO soldiers could have found themselves ta…
What use is an inflatable dummy tank in a very real war? A lot, if the enemy believes that it’s real. During World War I, Allied forces made use of dummy versions of the British heavy tanks. These were constructed from a wooden framework and covered with p…
