Light bulbsStarting in the early 1800s, inventors looked for ways to convert electricity into light.
Sir Humphry Davy, an English physician, successfully passed an electric current through platinum strips in 1801. Unfortunately, the strips evaporated quickly and Davy was unable to create a light that lasted more than a few minutes.
In 1809 Davy (England)created what would become known as the Arc lamp. He made an electrical connection between two charcoal rods connected to a battery. The light from this was very bright but small.
For the next 50 years, others sought ways to lengthen the amount of time the light source would remain. In 1840 Warren de la Rue, a
British scientist, placed a platinum coil in a vaccum tube. When he passed an electric current through it, light was formed. This design was efficient and the light lasted longer, but platinum was very expensive which made it impossible to be distributed on a commercial level.
In 1841
Frederick de Moleyns of England was given the first patent for an incandescent lamp. His design used powdered charcoal. He heated this material between two platinum wires in a vacuum bulb.

On the past June 15th, 2002, the US Congress officially recognized that the
italian inventor Antonio Meucci is to be credited for the invention of the telephone, and not Alexander G. Bell, as so far claimed.
AutomobileThis question does not have a straightforward answer. The history of the automobile is very rich and dates back to the 15th century when Leonardo da Vinci was creating designs and models for transport vehicles.
There are many different types of automobiles - steam, electric, and gasoline - as well as countless styles. Exactly who invented the automobile is a matter of opinion. If we had to give credit to one inventor, it would probably be Karl Benz from Germany. Many suggest that he created the first true automobile in 1885/1886
First Automobile - Nicolas-Joseph Cugnot (1769) France
STEAM / Built the first self propelled road vehicle (military tractor) for the French army: three wheeled, 2.5 mph
Robert Anderson (1832-1839) Scotland
Karl Friedrich Benz (1885/86) - Germany Patent DRP No. 37435
Gottlieb Wilhelm Daimler and Wilhelm Maybach 1886
and finally George Baldwin Selden (1876/95) United States GASOLINE / Combined internal combustion engine with a carriage: patent no: 549,160 (1895). Never manufactured -- Selden collected royalties
i am not sure Peanat butter .... but i do love Disney World in Florida( a wee expensive though)
