Floating Doorstep Anti-flood Defence
Hello
The New Scientist magazine, published in Britain, referred to my invention of a floating doorstep to protect buildings against flooding. This created a great deal of interest from the press, television, and radio stations, with a station as far away as Australia doing a telephone interview. I thought your readers may also be interested.
The device is automatic and acts as a conventional doorstep until activated by floodwater. Because the step is hollow it sits on the surface of the floodwater and is always above it. A fexible bag is attached to the step and floodwater inflates it, providing a screen across the doorway.
In effect the energy of floodwater is being used to repel itself. Some development work has been done at Abertay University Scotland. The device is being patented.
Best wishes
