Trying to predict the future can be difficult if not impossible. What appears to be the next success
story now might be thrown in the bin tomorrow. However, there are inventions that have the
potential to alter the world we now know.
The DEKA prosthetic arm will allow amputees to raise their hands above their heads. This lets
them perform much more complicated tasks than ever before.
The Smart Pipe is designed to reduce the amount of wasted clean water by monitoring water flow
and leaks in public water systems. The leaking is estimated to have cost millions of dollars
annually in the US.
In the future you might end up seeing delivery people and construction workers wear Titan Arms.
In addition to helping them lift heavy things, Titan Arms could be used by people with back
injuries caused by lifting heavy things or even by people recovering from a stroke.
Slingshot is a device made to clean water from almost any source. One device would be sufficient
to serve the needs of 300 people. After a decade of being developed, the Slingshot technology is
now to be taken to parts of Africa and Latin America.
