The world’s oldest engine is on the verge of getting a new life in a big way.

The engine that powered the British navy from 1750 to 1800, which ran on coal-fired boilers, has been found abandoned in the Gulf of Thailand in a small cove off the coast of Thailand.

It was abandoned at a depth of 6,000 metres (20,000 feet) and was corroded by the salty sea water.

The engines had been converted from diesel to a compressed gas turbine engine in the 1950s, but the Thai government had to halt the conversion because of the rising sea levels and the rising cost of diesel engines.

The new engine will be powered by a specially built, carbon-fibre composite, and will be able to run on the current diesel engine, which was replaced in the 1970s by the more efficient hydrogen fuel-cell system.

It is not the first time that the engines have been found in the sea.

Last year, a diesel engine was found in a shallow sea off the shores of Singapore, but experts had to drill down through the sand to find it.

The latest discovery was made in a deep, shallow sea about 10 metres (32 feet) below the surface.

It had been submerged for decades, but it is not clear what caused the engine to have been abandoned there.

The engine was badly corroded and had been covered with rust.

Experts believe the engine was abandoned because it was not built to run the new hybrid fuel-turbine engine.

It will not have a good future in the shallow sea.

The diesel engines have become an object of fascination for marine engineers and scientists worldwide.

In the US, the engines were developed to replace the old coal-burning boilers used by British ships.

In Japan, they are being developed as replacements for older diesel engines used in the early 1900s by Royal Navy ships.

The British navy had its first diesel engines in the late 18th century and they were powered by coal.

They ran on gas.
