Model S

Model S
The National Highway Traffic Safety Administration Safety Model S is designed from the ground up to be the safest car on the road, as proven by a 5-star rating in all categories of the National Highway Traffic Safety Administration (NHTSA) crash test. Much of its safety is owed to the unique electric drivetrain that sits beneath the car’s aluminum occupant cell in its own subframe. This unique positioning lowers the car’s center of gravity, which improves handling and minimizes rollover risk, and replaces the heavy engine block with impact absorbing boron steel rails. Side impacts are met by aluminum pillars reinforced with steel rails to reduce intrusion, protecting occupants and the battery pack while improving roof stiffness.

Listen up, America: It’s time to start making mass transit free! In March, when a cloud of particle pollution settled across Western Europe, Paris took a radical approach. The Ile-de-France region introduced alternate driving days (odd-number plates one day; evens the next) and eliminated fares on local trams, buses, trains and subways. Traffic dropped by nearly 20 percent in Paris; congestion on the Périphérique ring road fell by 30 percent at rush hour; large-particle pollution fell by 6 percent.

Helsinki's ambitious plan to make car ownership pointless in 10 years The Finnish capital has announced plans to transform its existing public transport network into a comprehensive, point-to-point "mobility on demand" system by 2025 – one that, in theory, would be so good nobody would have any reason to own a car. Helsinki aims to transcend conventional public transport by allowing people to purchase mobility in real time, straight from their smartphones. The hope is to furnish riders with an array of options so cheap, flexible and well-coordinated that it becomes competitive with private car ownership not merely on cost, but on convenience and ease of use.

New electric wheel kit converts any bike into a cardio-controlled offroad ebike This rugged electric bike conversion kit, which is robust enough for offroad cycling, offers a unique feature that uses your heart rate to control the amount of assistance coming from the motor. There are a variety of brands and models of electric bikes on the market these days, but if you love the bike you already own, then buying a whole separate bike just to get electric pedal-assist is a bit of overkill. A better solution might be to get an electric bike conversion kit, which can allow you to keep your favorite bike while also taking advantage of the benefits of an ebike. We've covered a few different ebike conversion kits in the past, but there's a recent addition to the electric bike conversion market that may be worth a closer look, especially if you're a mountain biker or want a burst of speed during your "offroad" biking.

Voitures autonomes Officially, there’s no such thing as a self-driving car in Canada – at least, not one legal for you and I on a public road. But unofficially, there are quite a few we can take out for a spin. Infiniti, Audi, Volvo, Acura and others – they all have “active cruise control” available and increasingly clever “active lane assistance.” The first keeps them away from the car in front and the second keeps them in their lane. On a fairly straight stretch of highway, it’s quite safe to take your feet from the pedals and your hands from the wheel. They usually do this with a combination of sonic sensors, to judge their distance from the car in front and slow down when it slows, and cameras that read the lane markings to each side.

This Airplane Will Fly Around The World Without Using A Drop Of Fuel by Emily Atkin Posted on "This Airplane Will Fly Around The World Without Using A Drop Of Fuel" The Solar Impulse 2, which is due to make the first round-the-world solar flight, day and night without any fuel. CREDIT: Jean Revillard for Solar Impulse 2 via AP Images Homopolar Motor with Liquid Metal Brushes - Revolution-Green They claim their technology harnesses the power of highly compressed magnetic field to produce far greater reaction than the compressed fluids used in conventional and jet engines. Power to weight can be in excess of 30:1 kW/kg. I like to thank Uli who is a regular commentator at Revolution -Green fro finding this website. Uli is still able to post also at Free Energy News a increasingly rare privilege.

Don't Privatize and Reduce Public Transit, Make It Free and Expand It (Photo: Wikipedia)As BuzzFlash at Truthout has been beating the drum about the gloomy imminence of the disastrous impact of climate change, it is worth noting that among the larger contributors to global warming are gas-powered vehicles (think cars and trucks). It's not just the carbon dioxide emitted by automobiles, it's the fossil fuel nightmare that has been created by expanding urban areas to exurban locations located at great distances from city centers. This, in turn, requires more inefficient use of energy (most of it still fossil fuel based) and more car use through the building of more expressways. According to the Union of Concerned Scientists: Passenger cars and light trucks represent the lion’s share of US transportation emissions and collectively produce almost one-fifth of the nation’s total global warming pollution. All together, transportation generates nearly 30 percent of America’s global warming emissions, including more than one-third of all US carbon dioxide emissions.

Meet Proterra, The Next Generation Of Bus “Everything that has an urban drive cycle will ultimately be an electric vehicle.” That’s what Ryan Popple, the president and CEO of Proterra, the leading U.S. electric bus company, explained to me in a recent interview. The future of transit isn’t cleaner diesel, hybrids, natural gas, or hydrogen fuel-cell buses, argues Popple. The rapidly dropping price for electric batteries combined with new fast-charging technology appears to render the competition obsolete. Right now, the biggest question isn’t which technology will win in the bus market — it’s how quickly all-electrics will take over, and whether Proterra can keep ahead of the Chinese competition, like electric vehicle giant BYD. Popple is focused on electrifying the transit market, which he expects “will be 100 percent electric” in a decade or so.

The 500,000 + Piece LEGO Car That Runs on Compressed Air Below is a video of a plastic car built almost entirely out of LEGO parts, more than 500,000 to be exact. It only needed tires and a few suspension parts that were not made out of LEGO. It consists of four orbital engines which hold 256 pistons inside. It travels at a speed between 20-30 km/h and runs completely off of compressed air. It was designed and built by 20-year-old Raul Oaida from Romania. This raises the obvious question, if a LEGO car can run on compressed air, can we do so the same with conventional automobiles?
