A Colorado Firm Claims It Can Triple the Power of Electric Engines


The team started from scratch, looking at the various components of the electric motor. Comprised of a gearbox, a power delivery system, and a main motor, these components are usually housed separately to allow sufficient cooling space, without which could result in engine failure.

However, using advances in material science and electronics, coupled with the ability to 3D-print structures such as copper, the team managed to put all components together into a single housing that weighs just 33 pounds (15 kg) without impacting their cooling needs.

Apple’s Most Back-Ordered New Product Is Not What You Expect

OAKLAND, Calif — Apple this month unveiled an array of new gadgets: more powerful MacBook laptop computers, AirPod wireless headphones with longer battery life and HomePod Mini speakers in three more colors.

But a different and unheralded Apple release is garnering so much interest that it has become the company’s most back-ordered new product: a $19, 6.3-by-6.3-inch cloth to wipe smudges and fingerprints off screens.

The US Copyright Office just struck a blow supporting the right to repair


The US Copyright Office is expanding a legal shield for fixing digital devices, including cars and medical devices. This morning, the office submitted new exemptions to Section 1201 of the Digital Millennium Copyright Act, which bars breaking software copy protection. The resulting rules include a revamped section on device repair, reflecting renewed government pressure around “right to repair” issues.

Super-efficient linear compressor could vastly reduce air con power use


So compressor efficiency is set to be a very big deal in the coming decades, and by proxy, that makes Magtor's Magtorpressor a device worth looking into – because this Maltese company claims its demonstrator units are already delivering 90 percent more pressure than the average air compressor for the same power consumption, and some 29 percent more than the best current devices on the market.

How? Well, Magtor does away with the rotating crank and piston assembly used by today's standard reciprocating designs, replacing it with a much simpler linear oscillating design capable of compressing air in both directions as it moves back and forth.

Can ocean cleanup boats power themselves by turning plastic into fuel?


With the amount of plastic swirling around in the ocean, wouldn't it be handy if the boats charged with cleaning it up could use the trash to fuel their own operations? A new study has crunched the numbers on such an approach and found that ships carrying reactors to convert the waste into "blue diesel" could indeed power themselves, which would reduce the need for trips back to shore and the associated burning of fossil fuels.

Waymo will start operating in New York City


Much of Waymo's self-driving vehicle use has largely focused on warm climates, but it's about to give those machines a harsher trial. Waymo will start driving its autonomous Chrysler Pacifica vans in New York City on November 4th. This and a later wave of Jaguar I-Pace EVs will rely on human drivers to map streets and learn from the environment, and there aren't any immediate plans to offer driverless rides to passengers. However, Waymo clearly hopes to use this knowledge for its long-term autonomy goals in various cities.

Coal could find new use in eco-friendly desalination tech


The burning of coal may be falling out of favor as a means of generating heat and electricity, but that doesn't mean the material no longer has any valuable uses. According to a new study, it could be utilized in the desalination of seawater.

In a project led by Assoc. Prof. Andrea Fratalocchi, a team at Saudi Arabia's King Abdullah University of Science and Technology (KAUST) explored the use of a material known as carbonized compressed powder (CCP). It is created by grinding coal or charcoal into a powder, then compressing that powder back into a solid which is more porous than the original material – it can also be molded to a desired shape.
