IAW CXCVII - Ingenious Inventions

Throughout history our means by which to hunt, cloth and feed ourselves have evolved. From the bone implements of the pre-historic peoples to the advanced instruments and equipment of the Modern Era. Ever since we weren't forced to hunt for food we could find time to think up new solutions to everyday issues. The theme for this week is... INGENIOUS INVENTIONS
Im looking forward to view and comment on your entries. Enjoy.
Wish you all...

All the Best from Anders

In addressing the question of who invented the incandescent lamp, historians Robert Friedel and Paul Israel list 22 inventors of incandescent lamps prior to Joseph Swan and Thomas Edison. They conclude that Edison's version was able to outstrip the others because of a combination of three factors: an effective incandescent material, a higher vacuum than others were able to achieve (by use of the Sprengel pump) and a high resistance that made power distribution from a centralized source economically viable.

The Rules:

Each week we will post an original photo with words on it. The idea behind this group is to expand our minds through our photography.
Photos must be your own, but the words can be someone else's as long as credit is given after the words.
Your post can either be serious, or if you'd like comical, but never obscene .
Posts can either have one word on them,quotes, or full poems ... Your choice.
All posts are to be done on your own site in a blog form with a link back to it being left here. New topics will be posted on Sundays.
Posts can be made through Saturday.
One post per person only please.
