Forget in-office gyms, slides and nap rooms.

If you want to attract the best talent, what you really need is a rollercoaster.

This is according to billionaire, Elon Musk, who says he wants to build giant office rollercoasters for his employees at Tesla and SpaceX.

'It would take you around factory but also up and down. Who else has a roller coaster?,' said Elon Musk

'Everybody around here has slides in their lobbies,' he said. 'I'm actually wondering about putting in a rollercoaster - like a functional roller coaster at the factory in Fremont.

'You'd get in, and it would take you around factory but also up and down. Who else has a roller coaster?

The comments were made in Musk's recent biography, 'Elon Musk: Tesla, SpaceX and the quest for a fantastic future'.

'I'm thinking about doing that with SpaceX, too. That one might be even bigger since SpaceX has like ten buildings now,' said Musk'

'It would probably be really expensive, but I like the idea of it.'

SpaceX has more than 3,000 employees at its headquarters in Hawthorn, California and Tesla has around 6,000 employees at its headquarters in Palo Alto.

EMPLOYEES IN A GOOD MOOD ARE 12% MORE PRODUCTIVE Researcher has shown that Elon Musk may have the right idea - and that happy employees really do work harder. In a series of lab tests last year, scientists found happiness made people around 12 per cent more productive. The study by Warwick University included four different experiments with more than 700 participants. During the experiments a number of the participants were either shown a comedy movie clip or treated to free chocolate, drinks and fruit. Others were questioned about recent family tragedies, such as bereavements, to assess whether lower levels of happiness were later associated with lower levels of productivity. 'The driving force seems to be that happier workers use the time they have more effectively, increasing the pace at which they can work without sacrificing quality,' said Dr Daniel Sgroi.

It also has a number of satellite offices, include one in Fremont, California.

'I think our Tesla headquarters looks like crap,' he added. 'We're going to spruce things up.

'Not to sort of the Google level. You have to be like making money hand over fist in order to be able to spend money the way that Google does.'

Google famously offers its employees everything from laundry facilities to volleyball courts - and even naps pods and a slide.

And with a rooftop pool, an indoor football pitch and a private climbing wall, Google's vision for its Kings Cross headquarters could be even more lavish.

The architect's plans showed pictures of staff cycling between meetings, and lounging about in cosy nooks in a carefully manicured roof garden.

But Google boss Larry Page recently ordered the extravagant plans to be ripped up because they were too boring.

Google's current offices rival YouTube's hip San Bruno headquarters, where staff have a putting green and slides, as well as treadmills linked up to computers.

The 550 employees who work at the California headquarters can enjoy nap pods, massage chairs, scooters and food cooked by a top chef.

Nearly every need is catered for at the workspace - for employees and their pets. Many of the staff bring their dogs to work with them every day.

While it seems excessive, scientists claim YouTube, Google and Tesla have the right idea in creating 'fun' offices.

Recent research has found that keeping employees happy with slides and gyms make them work 12 per cent harder.
