# Five unpopular, amazing ideas
## Here's a lesson for future scientists - never give up. Here are five ideas
that took perseverance to take off.
Roger Highfield 3:11PM GMT 16 Dec 2010
**Gyro power**
The two-wheeled gyro car, patented by engineer Louis Brennan in 1903, used a
spinning gyroscope to stay upright on a monorail. The vehicle failed to catch
on, but entrepreneur Elmer Sperry bought the patents, founding the Sperry
Gyroscope Company to make ships' equipment; today, gyroscopes are used in much
guidance, steering and stabilisation equipment.
**Killer proteins**
When research suggested that puzzling spongiform brain disorders like scrapie
in sheep could not be transmitted by a bacterium or a virus, Stanley Prusiner
suggested a new infectious agent: a rogue protein known as a prion. The idea
was so outrageous that he was ridiculed, but doggedly pursued it. In 1997 he
won a Nobel prize.

**Heavier-than-air flying machines**
A few centuries ago, scientists and the public were adamant that flight was
impossible with an artificial wing. But English scientist George Cayley
disagreed, building increasingly complex model flying machines, culminating in
a full-scale glider which flew in 1853. His pioneering work was a huge
inspiration for the Wright brothers.
**Boring measurements**
In the early Eighties, like today, British research, including the measurement
of atmospheric ozone in Antarctica, faced government cutbacks. Then, in 1985,
Joe Farman, Brian Gardiner and Jonathan Shanklin measured dramatic losses of
ozone, which showed everybody how human activity can damage the global
climate.
**Electromagnetic shock**
Perhaps the best-known example of an unlikely idea that worked came from
Michael Faraday, who developed the electric motor then found that a magnet
moving in a metal coil was able to induce a current. When an eminent
politician asked Faraday: "What good is it?" Faraday replied: "Soon you will
be able to tax it." By the 1880s, electric power was in widespread use. And,
of course, taxed.

For 20 years the Hubble Space Telescope has shown us amazing images like
these. Giles Sparrow, author of Hubble: Window on the Universe, explains why
it's a modern marvel.

Graphene is harder than diamond, just a single molecule thick and conducts
electricity. Kat Hannaford talks to the two Nobel prize-winning scientists who
discovered it about why it could revolutionise everything.
