How do you improve a great invention like the bicycle? For one company, it means removing its chains.

CeramicSpeed, a manufacturer of bicycle parts, has teamed up with the Mechanical Engineering Department of the University of Colorado to create an innovative bike that’s being marketed as the “world’s most efficient.”

CeramicSpeed’s concept bike drivetrain Driven is completely chain-free.

How does the bike exactly work, you ask? And how is it different from a regular bicycle, apart from being chainless?

Well the official CeramicSpeed website tells us that Driven “sets a new benchmark in drivetrain technology, increasing optimal efficiency to 99% and creating 49% less friction than market leaders.”

Unlike other drivetrain systems, this new tech removes friction “caused by the articulation of a chain due to it’s innovative pinion drive shaft design.”

Or as Jason Smith, chief technology officer of CeramicSpeed, puts it: They made the bicycle aiming “to create a drivetrain that only had one-percent frictional losses.”

Driven is equipped with 21 hybrid bearings by CeramicSpeed.

Every bearing comes with unique ceramic balls that are “58% lighter and 2.3 times harder than traditional steel, increasing the speed of the bearing by 30-50%.”

Currently, Driven is still under development and doesn’t have a release date yet.

So yeah, don’t expect to see this bike in the market anytime soon as it is still a work in progress. Still, its impressive to know that Driven has already won the Eurobike Award, “a competition that included 365 other entrants” reported Maxim.

As for now, you can check out the video below for more details about the chainless Driven drivetrain bike:

This female astronaut has definitely boldly gone where no Star Trek fan has ever gone before! We are, of course, talking about Samantha Cristoforetti, a European astronaut and a certified Trekkie, who rocked a Star Trek uniform and took a selfie while she was in space.

According to reports, the photograph was taken while Cristoforetti was aboard the International Space Station. She later posted the image on her Twitter and it went viral from there.

"'There's coffee in that nebula' ... ehm, I mean... in that #Dragon," said Cristoforetti in her tweet.

World hunger may no longer exist in the near future. China has just developed a new grain of rice that thrives in seawater. The amazing development could feed up to 200 million people on a regular basis.

Researchers took their plan to a field in the coastal city of Qingdao in the eastern Shandong province in China. The location was chosen for its vicinity to the Yellow Sea. The scientists planted up to 200 different types of grain to see which would grow best in salty conditions. One particular grain thrived, delivering up to 9.3 tonnes of rice per hectare.

China has been developing the seawater rice for several decades.

The time has come for anyone who dreamt of cruising in a Hoverbike since seeing Return of The Jedi. Hoversurf has created the world's first personal hovering vehicle. It's currently available for pre-order but doesn't come with your own personal Princess Leia or band of Ewoks.

The Hoverbike S3 2019 has a carbon fiber body and looks like a traditional quad bike with four heavy-duty propellers. The model also promises new ergonomics on the pilot's seat so you can sit comfortably at any height. The bike's weight is 114 kg (253 pounds) but it can still hover properly. You can still reach an altitude of 16 feet and go up to the maximum speed of 96 km/h (60 mph or 52 knots).

The world's first Hoverbike will start rolling out in 2019.
