World's Oldest Lightbulb – Working for 111 years
The world's oldest light bulb has been burning for 111 years - so little
wonder it has a fan club with thousands of members and its own website.
As EU rules deny householders the right to use traditional filament
bulbs, the so-called 'Centennial Light' has been on almost constantly
since 1901. It holds pride of place in Fire Station 6, in Livermore,
northern California.
The longest time the Guinness World Record-holding bulb has ever been
turned off for is just a week. Dangling above the fire engines, people
come for hundreds and thousands of miles to see the diminutive symbol.
The bulb was designed by Adolphe Chailet, who competed with the likes of
the world-famous Thomas Edison to make the best bulb.

World's Oldest Vacuum Cleaner – Working since 1904
Still sucking after 108 years, Harry Cox owns the oldest known working
vacuum. He rescued the cleaner and accessories from a skip at work
before it went to a landfill site. Harry, at 53, less than half the age
of his 1904 American Sturtevant vacuum cleaner No.4 said, “There was a
walk-in skip at the factory and I rescued it.”
Despite his enthusiasm for old machines, his wife Jacqueline ignores the
noisy, heavy antique and prefers to clean their three-bed semi in
Timperley, England, with a more modern model.

Old Refrigerator – Working for 77 years
It was the era of the Great Depression, a decade of austerity when
household finances were stretched. So when the Kinghorn family bought a
brand new refrigerator in 1936 they hoped it would prove a good
investment. They could never have imagined that three quarters of a
century later, with the nation again facing tough economic times, the
fridge would still be working as well as ever. The Frigidaire – a 1935
model – is now a contender for the title of the oldest
continuously-working refrigerator in the country. It has never needed
repairs, apart from the occasional replacement part. It takes pride of
place in the kitchen of Rosemary Kinghorn, who inherited the appliance
when her mother-in-law, the original owner, died in 1957. The
79-year-old said it had not had any maintenance for over 30 years, when
her husband last replaced one of the parts.
Mrs. Kinghorn, of Marchmont, Edinburgh, said the refrigerator was one of
the last to be built without a light, but served as a reminder of an era
in which things were built to last.

Oldest Working Computer – Working since 1958
In Japans Ikeda Memorial Hall sits the FACOM 128B that was built in 1958
and still works today! It has gone through some small upgrades over the
years to keep it running, but still has the same core system. The FACOM
occupies 700 feet of floor space and has less calculating power than a
real calculator. The company's goal is to keep it running until the year
2016 when it will have reached its 60th year of operation.

Oldest Humanoid Robot – Built in 1950
He didn't have any intelligence. And he moved with just a slow,
lumbering shuffle of his metallic feet. But one of Britain's first
humanoid robots, built just after the Second World War, has been given a
new lease on life after having languished in a garage for the past 45
years. Former spy catcher and RAF officer Tony Sale, 79, built the
incredible 6 ft-high robot, George, in 1950, for just $20. using scrap
metal from a crashed Wellington bomber plane. At the time Mr. Sale was
only 19 and his amazing man-sized model, which could walk and ‘talk,'
stunned the world.
Sadly, computers of the time were too crude and big to give George
memory and intelligence so he was packed away in Mr. Sale's garage in
Bedford and left to gather dust. But now after nearly five decades Mr.
Sale has got the radio-controlled robot working simply by putting in two
new batteries and oiling his joints.

Britain's Oldest TV – Working for 75 years
For £5,000 you might have expected a bigger, flatter screen. But this
television does come with 75 years of broadcasting history – and you can
still hook it up to a Freeview box. Built in 1936, the Marconi type-702
is the oldest working television set in Britain. It was bought for just
under £100 only three weeks after transmissions in Britain began. And
with just one channel broadcasting for two hours a day, there wasn't
much need for a remote control.
But what the television lacks in modern technology, it makes up for in
reliability. Only 30 per cent of its components have been replaced
during its lifetime, all with identical parts.
The 75-year-old set has a 12-in. screen contained in a walnut and
mahogany case, with the picture reflected on to a mirror for the viewer
to look at. The TV has now a pre-sale estimate of £5,000, but experts at
Bonhams expect it to fetch much more. It cost Mr. Davis £99 and 15
shillings – more than half the annual average wage at the time and
equivalent to almost £4,000 today. Its serial number is H1007, and it is
thought the sequence began at 1,000, making it number 7.
