11 states sue EPA over attempt to reverse ban on ozone-harming HFCs
The Scott Pruitt-era EPA is facing yet more legal action over its attempts at reversing US environmental regulations. A group of 11 states (including New York and California) and the District of Columbia have sued the EPA for violating the Clean Air Act by "effectively" lifting a ban on climate-changing hydrofluorocarbons (HFCs). The states contend that the agency's April "guidance" document illegally removed the entire HFC ban rather than going through the necessary public rulemaking process.
Treaty ending use of planet-warming HFCs takes effect in 2019
The treaty phasing out the use of Earth-warming hydrofluorocarbons now has an official start date. Sweden has become the 20th country to ratify the Kigali Amendment, invoking a clause that has the measure taking effect on January 1st, 2019. From then on, wealthier countries (less fortunate nations have until 2024 or 2028) must cut back on use of the greenhouse gas in everything from air conditioning to refrigerators. Ideally, this pushes companies to use and develop eco-friendly coolants.
Mercedes-Benz aims to take hydrogen fuel-cells mainstream
General Motors' confidence in hydrogen fuel cell (HFC) vehicles seems to be sparking something of a renaissance among other automakers. In April, Toyota announced it was testing a HFC semi truck, and now Mercedes has announced a hybrid crossover utility vehicle that combines the pricey alternative-fuel tech with something a little less exotic: a battery-powered electric vehicle. The GLC F-Cell will carry 4.4 kilograms of hydrogen onboard, in addition to its 147 kilowatt lithium-ion battery. The automaker says that the the F-Cell's range can hit 437 kilometers (roughly 271 miles) with a governed top speed of 99 MPH, and that it'll charge in about 1.5 hours.
The Army could save hydrogen cars from a premature death
Over the past 25 years, hydrogen fuel cells (HFC) have been the butt of countless jokes in the automotive industry. Many critics see the technology as something long in the works that will never have a future. It's seen some spotty progress over the past decade, existing alongside compressed natural gas vehicles. But in terms of public perception, HFCs are still on the fringe compared with plug-in hybrids and electric vehicles. In 2016, the Los Angeles Times reported that Toyota expected to sell 3,000 of its $60,000 Mirai sedans by the end of 2017 -- and that was an optimistic forecast, mind you. In contrast, Tesla racked up over 232,000 preorders for its all-electric Model 3 sedan in just 24 hours, and Toyota crossed 3.9 million in global sales for the Prius in February.
Gordon Murray reveals new Batmobile, Dark Knight gets serious about reducing carbon footprint
So you've finished building your Batman Forever-style Batmobile, your Tumbler's up on blocks in the front yard, and you're itching for a new project. It's not too early to start planning a DIY version of Gordon Murray's newly unveiled Bat-ride (part of the Batman Live World Arena Tour). The designer drew on his experience with the McLaren F1 for his new concept car, which includes a healthy dose of imagineering: there's a carbon-fiber body that "breathes," as well as LED-lit "virtual wheels." We're not sure how carbon fiber breathes or what virtual wheels are, but as Murray explains in the video below, they're based on Formula One materials as he imagines them 15-20 years from now. He also envisions a greener Dark Knight, whose ride runs on hydrogen fuel cells and lithium-ion batteries -- no longer will the caped crusader suffer a guilty conscience due to his excessive carbon dioxide emissions.
RC car runs on soda can rings, Doc Brown approves (video)
Many a future engineer was inspired by Back to the Future's Dr. Emmett "Doc" Brown, and not just because he proved that unkempt eccentrics could truly change the world. No, he also pioneered Mr. Fusion, the coffee maker/cold fusion reactor that turned garbage into energy. And while we're still waiting for cold fusion and time travel to become a reality, today we're all one step closer to waste-powered cars. A pair of Spanish engineers have recently unveiled the dAlH2Orean (see what they did there?), a R/C car that runs on aluminum. Dropping a few soda can tabs into a tank of sodium hydroxide produces enough hydrogen to power the little speedster for 40 minutes – at almost 20mph. Hit the video above to see it in action, along with your daily helping of the Chemical Brothers. Fitting.
Now you're playing with ... no hands
Never one to shy away from innovative gaming setups, Nintendo experimented with dozens of unusual peripherals and controllers decades before the Wii remote debuted its motion sensing capabilities. The NES's Hands Free Controller, a 2.5-pound device that strapped over your chest and provided a chin-fitted joystick (or a foam-covered ball) as its directional pad, was definitely one of those unconventional setups. Using an articulation tube, physically-limited gamers with special needs could "sip and puff" with the HFC instead of pushing the A and B buttons on a traditional controller. Sipping and puffing with more force would translate into hitting Select and Start. The button modes and pressure settings were adjustable with several knobs and switches on the device's control panel. Because it was never sold in stores and was only available for purchase through Nintendo's customer service line, the HFC is one of the most rare NES accessories out there. An unused bundle that showed up on eBay recently commanded a Buy It Now price of $379.99! Head past the post break for some old magazine scans advertising Nintendo's Hands Free Controller.
