Batteries

Wednesday, October 29th, 2008

Many things are noted as moments of great advancement of mankind - the making of fire, weapons (they an advancement?), steam power, the wheel and the list goes on and on. I don't think I have ever seen anyone mention the battery but where would we be without them? Just think how many batteries there are around your home and where you would be without them.

Oh yes, you could use a candle instead of a torch but a candle won't work a portable radio. And then outside, there is your car. How many of you, have hand cranked one? Yes it works, but you have to watch your thumb. Just imagine the sympathy from fellow road users if you had to get out and hand crank if you stalled at the traffic lights.

But then I was chemist and batteries are an example of practical chemistry personified - your own little chemical experiment going on with you even noticing. Love them.
