In the Independent back in May last year there was an article about portable solar energy packs. The Tag lines were “Solar has always been fixed to the roof, but kids can carry ours on their back packs”

By September The Mail on Sunday another use had been found for this ingenious invention.

“Frontline troups could soon be carrying a new piece of high-tech gear into battle - solar panels.”

Soldiers will have them moulded onto their back packs to help power the array of electronic equipment now used in combat.

Well I never!
