The purely air-powered can't may not be a reality, but is a clever way to use compressed air to store energy for later use.



Let's be clear: There's no such thing as a truly air-powered car. But PSA Peugeot Citroën has a new take on how to use compressed air to store energy that a car can use for propulsion. Showcased in two concepts, a Citroën C3 and a Peugeot 208, the Hybrid Air system powertrain combines air, hydraulics, and gasoline. Peugeot claims its system improves fuel economy by 35 percent and is capable of 81 mpg in the New European Drive Cycle test. A projected price of about $26,000 means the Hybrid Air would be roughly $7700 less than what a Toyota Prius costs in Europe. If Peugeot brings out the Air Hybrid in 2016 as promised, it could challenge electrical batteries as a hybrid power reservoir.

How it Works

An 82-hp 1.2-liter gasoline engine provides most of the power, driven through an epicyclic automatic transmission. During deceleration, the wheels' energy drives a hydraulic pump that pushes hydraulic fluid into an accumulator and compresses the nitrogen gas within. When the car needs to accelerate, the system works in the opposite way: The pressurized nitrogen gas pushes the hydraulic fluid, which drives a hydraulic motor connected to the transmission.

Driving Modes

Gas only: Intended for highway driving
Air only: For speeds below 43 mph, where the engine stops and hydraulics power the wheels 80 percent of the time
Combined: Powered by the gas engine and hydraulic motor


Feasibility

Hydraulic systems are an established technology. The motors and pumps are simple, relatively low-cost, and easy to package—as are epicyclic gears—so the Hybrid Air could be lighter and cheaper than a gas–electric hybrid. And unlike chemical batteries, hydraulics have fewer recycling issues.

Roadblocks

With no big battery to run the air conditioning at standstill, the engine would have to run, using gas; a crash-safe accumulator large enough to hold the requisite amount of pressure (up to 4351 psi) might be heavy enough to negate any benefit. With unproven reliability, hydraulic systems could find it difficult to gain consumer acceptance.

For almost the entirety of Firefox’s 12-year history, Mozilla — and thus Firefox — has been primarily funded by a lucrative deal with Google. Since 2004, Google has been paying Mozilla around $100 million per year — or about 85% of Mozilla’s total income — to keep Google as the default search provider. Today, that finally changes: Google is out and Yahoo is in. Kind of.

If you've ever signed up for an account or bought anything online, chances are you've had to fill out a CAPTCHA. It's that small box that asks you to type in a few words or a series of characters that have been distorted in an image (sometimes to a point you can't really tell what they are.) The idea is that machines can't read the letters and numbers, making this a good way to prove you are in fact not a robot.

It's a service provided by Google's reCAPTCHA. However, Google recently discovered that artificial intelligence robots could solve even the most difficult CAPTCHA thrown at them with a 99.8 percent accuracy. To combat that, Google implemented an Advanced Risk Analysis for CAPTCHA that determines how long you engage with a CAPTCHA to prove your human. Now, it's evolved that technology into something even better.

Unveiled today, the new "No CAPTCHA reCAPTCHA" finds out whether you're a robot just by asking you. It uses an API that can confirm your human status with just a click instead of typing in numbers and letters. It's a lot simpler from a user perspective, and a whole lot more secure.

In instances where the API can't determine you're human on its own, you'll be kicked over to an old-school CAPTCHA to get the job done. There's also a new mobile-friendly version of CAPTCHA that has you select similar images rather than zooming in on some awkward lettering on a tiny screen.

Google is already trying out the new No CAPTCHA reCAPTCHA with Snapchat, Wordpress, and Humble Bundle, and those sites are reporting positive results. On WordPress' site, for instance, more than 60 percent of its site traffic last week was able to get through with the new API and without needing to enter a traditional CAPTCHA. Humble Bundle was even better, with more than 80 percent of site traffic getting by with just the No CAPTCHA experience.

Expect to see more "I am not a robot" CAPTCHA boxes in your future.
