If paying for something with your smartphone still seems like a strange concept, then news that you’ll soon be able to do so with a selfie is likely all the more confusing. Indeed, though, MasterCard is set to roll-out both facial recognition and fingerprint payment authorization. read more

Hydrogen Car of the Future

Finally, a sleek, affordable British-built hydrogen-powered electric city car has arrived.

Hitting the roads from today, the electric car will reduce emissions, with just water coming from its exhaust, and it even has DeLorean-style gull wing doors.

Called Rasa, the green vehicle runs on electricity generated by hydrogen fuel cells and gives the equivalent of ‘250 miles to the gallon’, according to its backers.

Despite hydrogen being a highly-flammable gas, Rasa’s makers Riversimple insist the car is safer than conventional petrol models because the gas is contained in a pressurised tank and dissipates upwards in the event of a crash.

Although they’re still far from being common, 3D-printed metal bicycle frames do now exist. Usually they’re made using a sintering process, in which a laser is utilized to selectively melt steel powder, building it up in successive layers. Now, however, a team of students at the Delft University of Technology (TU Delft) in the Netherlands has taken another approach – they’ve created the world’s first stainless steel bike made via awelding-based 3D-printing technique. read more

The Hank Direct Bike offers an alternative to traditional folding bikes … and to chains or belt drives

Folding bicycles definitely have an advantage when it comes to easy toting and storage, although their chain presents a design challenge – it can’t just be folded sideways along with the frame, and there’s a risk that it will transfer gunk onto the rider’s clothing as they’re carrying the bike. read more

A Greecian Laptop?

Legend has it that the Oracle of Delphi connected priests with super natural beings who passed along advanced technology and information.

And conspiracy theorists claim that is how a modern-day laptop ended up in a Greek sculpture from 100 BC.

But historians say the sculpture is just a deceased woman ‘touching the lid of a shallow chest’.

The Rubbee 2.0 has a longer range and is “smarter” than the original model

While there are plenty of add-on electric bicycle motors out there, the Rubbee takes a particularly interesting approach. The product of a successful Kickstarter campaign, it incorporates a powered polyurethane roller that rubs against the bike’s rear tire (hence the name), helping to augment the rider’s pedaling power by driving the wheel forward. read more
