1814 Stephenson's Locomotive

STEPHENSON'S LOCOMOTIVE.
The accompanying photograph represents the first locomotive built by George Stephenson, which was constructed for the Killingworth Colliery Company, in the year 1814.
After doing its share of useful work as one of the notable pioneer locomotives, it came into the possession of Sir Charles Mark Palmer, who presented it to the mayor and corporation of the city of Newcastle-on-Tyne, England, on the occasion of the centenary of the birth of George Stephenson, which occurred June 9, 1881.
Free-Piston Sterling Refrigeration
Originally conceived in 1816 as an industrial prime mover to rival the steam engine, its practical use was largely confined to low-power domestic applications for over a century.

animation of basic absorption cycle using heat
Absorption cycle refrigeration without need for a pump was invented by two Swedish students, Carl Munters and Balizar von Platen at the Royal Institute of Technology in Stockholm. The machine they invented utilizes the fact that ammonia (NIL) is very soluble in cold water but much less soluble in hot water, while hydrogen is hardly soluble in either and balances the pressure throughout the system.

The cycle is
Work in with a compressor, to an heat exchanger heat out, to work done (turning a turbine or pushing a piston) to heat absorbed.

The Arc Electric Lighting
Brush Arc Electric LampsIn 1775, Italian scientist Alessandro Volta devised the electrophorus, a device that produced a static electric charge and in 1800 he developed the voltaic pile, a forerunner of the electric battery. Building on these electrical discoveries, Sir Humphry Davy found that bright sparks were given off when the voltaic pile was discharged and a specially bright spark could be obtained by using well-burnt charcoal as electrodes.
