I was looking through the current edition of Scientific American and saw a blurb on a device that attaches to your knee and as you walk it generates power. This is, as I remember, still in the development stage but if it ever becomes a usable device it might be a way for hikers to keep all sorts of batteries charged.

On a more serious note are there batteries out there that are better at holding a charge than others?I use my cameras intermittently so do not have a need to charge my batteries everyday as part of a normal routine. Having had a digital camera with a voracious appetite for batteries I decided to buy a dozen batteries, planning on keeping two recharged sets in the camera bag as spares.Alas all too often I found that not only the batteries in the camera but also the spares were unserviceable when I wanted to use them. Now I include a set of disposable batteries in my bag as back-up .MichaelPS my woes having been eased by a later camera which uses two AA batteries instead of four and which last longer when in use but the basic problem remains.
