The Hovercraft

The first time that it was mentioned in historical record of the principles behind hovering  was by the Swedish scientist Emanuel Swedenborg in 1716. But it wasn’t until 1915 that Dagobert Müller actually designed and built the world’s first air-cushion vehicle. experimentison of the hovercraft contuined beyoned the 1910’s. right through world war 2. it wasn’t until the American inventor Norman B. McCreary, who inventing and patenting the “Double-Walled Flexible Skirt”. Which would become the conventional design for the current hovercraft.

The Segway

the inventor of the seaway is Dean Kamen. the product was launched in 2002 an when launched it was claimed that the Segway was the future mode of transport for people and would eventually replace the car. well obviously this was not the case as global sales figures have shown that sales of the product have only reached into the tens of thousands. as it has been a flop. Dean Kamen did recently say that the Segway would can never completely replace the car, because it doesn’t have near the same capabilities. its speed range is 20 kph and it can only store enough energy for 24 km. that is in fact quite poor performance slightly faster than walking speed but only for 24 km . there are now electric mopeds that can reach 40 kph and last for over 30 km. that would make the Segway quite useless. also other reasons like each country defines the seaway differently e.g. some states don’t permit its use on side walks, roads or bicycle lanes. where some countries states that it must b insured and treated as a moped. so my view of the Segway is that it is a toy an expensive cool looking useless toy with no real world applications.
