He was famous as a lover of technology.

Whether it was piloting jets, sailing boats or subscribing to Flying Saucer Review, Prince Philip royal spent hours immersing himself in workings of mechanisms and machines.

Today, it is easy to forget that, for much of his time as husband and consort to the Queen, Philip was a decidedly modernising force in a rather stuffy monarchy, often to the discomfort of courtiers.

Gadgets were a particular favourite. It has been reported that, as a young Naval officer, Philip had air-conditioned his own quarters with a system of fans, radiators and thermostats. 

Some claim he had devised an early tea-making device – before the likes of commercial hit Teasmade entered the market.

More seriously, Philip served as the president of the British Association for the Advancement of Science.

According to the Royal Collection Trust, his interest ‘in many ways reflects and continues the role of the great-great-great-grandfather, Prince Albert.

And when, later, a giant water turbine was installed on the Windsor estate to provide energy for Windsor Castle, few doubted that the Duke of Edinburgh was a keen part of the planning.

As he once put it, ‘everything not made by God was made by an engineer.’

Even towards the end of his life, the restless Philip was keen to keep up with the latest gismos, devouring books on his Kindle screen, for example.

Prince Philip spent much of his time at Wood Farm on the Sandringham estate. While enjoying traditional pursuits such as carriage driving, Philip was keen to keep up with the latest gadgetry

Until he lost patience.

According to author Tina Brown in her best-selling book The Palace Papers, ‘Philip often extolled the joys of his Kindle until, disgusted by all the direct marketing of books he didn’t want to read, he threw it in the bathtub.’

This had apparently taken place at what Brown describes as his ‘man cave’ at Wood Farm, a simple house on the Sandringham Estate where the Duke of Edinburgh spent much of his retirement reading and painting.
