EMPOWERING HEALTHCARE
In many parts of the world hospitals have none of the
modern health equipment that is common in western
countries. This is partly because it is expensive, but also
because electricity supplies are often unreliable, while
trained staff who can read the complex displays may not
be available. Now, Freeplay Energy, the company which
developed the wind-up radio, is planning to introduce a
range of medical equipment which can be used in those
areas. All the machines will be of simple, robust design
which will either use solar power or foot pedals, making
expensive battery replacement unnecessary. Prototypes
are currently on trial in South African hospitals, where their
performance can be compared with more sophisticated
machines.
