Eco-friendly bitcoin competitor Chia, Invented

Share this

A bitcoin transaction wastes as much electricity as it takes to power an American home for a week, and legendary coder Bram Cohen wants to fix that. Considering he invented the ubiquitous peer-to-peer file transfer protocol BitTorrent, you should take him seriously. Cohen has just started a new company called Chia Network that will launch a cryptocurrency based on proofs of time and storage rather than bitcoin’s electricity-burning proofs of work. Essentially, Chia will harness cheap and abundant unused storage space on hard drives to verify its blockchain. “The idea…

Aluminium foil increases your wireless speed

Share this

Researchers at Dartmouth University have found that a 3D printed shape covered in aluminum foil can improve wireless range and increase Wi-Fi security. The project, which appeared on Eurekalert, involves placing a reflector on and around a Wi-Fi router’s antennae to shape the beam, increasing range and preventing it from passing through to unwanted spaces. “With a simple investment of about $35 and specifying coverage requirements, a wireless reflector can be custom-built to outperform antennae that cost thousands of dollars,” said Xia Zhou, a Dartmouth assistant professor. In their paper,…

New startup that helps you scan, send and print yourself

Share this

Kat Kinkead and Peter Weijmarshausen met at their old company, Shapeways. Weijmarshausen recently stepped down as CEO and was looking for something cool to do when he and Kinkead realized that the most popular application of 3D scanning and printing was in 3D figurines. These tiny action-figure-like representations were wildly popular print subjects back at Shapeways but they were notoriously difficult to capture and print. Now, thanks to improvements in scanning, color printing, and software, they’re surprisingly easy. Thus Beheld was born. Kinkead, the CEO, has an MFA in industrial…
