A small company in Wales is reinventing clean motoring with a handmade ecological car, the Rasa, powered by fuel cells and emits water rather than CO2.

In the U.S., air travel accounts for about a third of all Co2 emissions. A startup called ZeroAvia wants to clean things up in a big way.
ZeroAvia recently emerged from stealth with a zero-emission powertrain for small aircraft. It’s electric, but there are no big, bulky batteries involved. ZeroAvia opted for compressed hydrogen instead.
Why not use batteries? Compressed hydrogen is about four times as energy-dense as today’s best batteries. Founder, physicist and pilot Valery Miftakhov told FastCompany “actually getting a sizable aircraft in the air for a reasonable amount of time will be quite difficult with batteries.” That’s something he believes isn’t likely to change in the near future.
Before an A.I. system can learn, someone has to label the data supplied to it. Humans, for example, must pinpoint the polyps. The work is vital to the creation of artificial intelligence like self-driving cars, surveillance systems and automated health care.
Artificial intelligence is being taught by thousands of office workers around the world. It is not exactly futuristic work.

The few available range-extended electric car models give drivers added flexibility by using gasoline engines as onboard backup generators.
But using the range extender too often may consume a significant quantity of gasoline, somewhat offsetting the purpose of owning an electric car for some buyers.
Electric-car advocate Tom Moloughney faced that dilemma about two years ago, when he decided to buy one of the first BMW i3 electric cars in the U.S.
Imagine making the 2,710-mile trip from Philadelphia to Los Angeles using just one gallon of gas.
You might look silly doing it, but students from Université Laval, in Quebec, have theoretically made that outlandish trip possible with their prototype gasoline-powered car that gets 2,713.1 miles per gallon.
The Laval team took home the big prize at this year’s Shell Eco-marathon Americas, a competition in which university students design a prototype car using various fuels, from gasoline to hydrogen fuel cells, in an attempt to maximize efficiency on a Detroit, Michigan test track.
Tesla CEO Elon Musk says that the automaker is working on a new battery pack to come out next year which will last 1 million miles.
When talking about the economics of Tesla’s future fleet of robotaxis at the Tesla Autonomy Event yesterday, Musk emphasized that the vehicles need to be durable in order for the economics to work:
“The cars currently built are all designed for a million miles of operation. The drive unit is design, tested, and validated for 1 million miles of operation.”
This week, two companies say that their technologies were able to work together successfully broker and transport a load without any human help.
On Thursday, July 8, Starsky Robotics and Loadsmart issued an announcement about the trucking industry’s first autonomous dispatch and delivery.
The companies say that this “marks the first time an autonomous company and a digital broker have collaborated to price, book and load a shipment without any human involvement.”
A software engineer has built an impressive real-time counter-surveillance tool for Tesla vehicles on top of Sentry Mode.
It looks like something the CIA or James Bond would have in their car.
