In remote and poor places, batteries are expensive and hard to comeby.
Radios are of course of great value not only for news but for useful information such as weather forecasts.
One might add that even in developed and rich places, mains electricity does from time to time fail.
A wind-up clockwork (batteryless) radio is hardly rocket science, but one must wonder why this invention was not thought of before.

Clockwork Torch
Later on, Baygen introduced a clockwork torch. Weighing about 1 kg, the clockwork torch incorporates two improvements over the clockwork radio. First, the on/off switch halts the spring from escaping. Secondly, internal enegy storage keeps the torch shining while the spring is rewound. One version of the clockwork torch is enclosed in clear plastic so that the inner workings can be seen.
The award winning BayGen wind-up radio has grabbed quite a few headlines around the world in the last few months.
The BayGen FreePlay Wind-Up Radio is ideal for emergency use, cottages, boats, camping, teenagers, hunters, remote areas or anytime in these last days.
The BayGen Radio will pay for itself in just over a year with the savings on batteries.
