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.

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.
