Watch: video suggests you’re paying for car wheel spokes you don’t need

When trying to explain the physics behind driving a car, you can go the charts-diagrams-and-calculations route or you can go the tinkering-until-something-breaks route.When it comes to answering the questions Can you drive a car on a wheel with all but three spokes cut out? Two spokes? One? Russian YouTuber Garage 54 chose the latter, pulling off an interesting and, uh, scientific experiment by completely destroying some old rims.His YouTube channel works basically like a Russian car-themed Mythbusters — we really dig the clip where he tries driving a Lada with four engines strapped end-to-end.But more than that one, we dig his most recent video. It starts with a bunch of junk, some mismatched wheels and a question: how many spokes can you cut out and still drive?After being fitted to the car, each of the three wheels receives some added lightness by way of removing the spokes, one by one. First, a six-spoke wheel is cut down to three; a 16-spoke is cut down to eight; and an eight-spoke cut down to four.None of the wheels seem to notice the lack of structure, and perform their job dutifully. Its when the wheels start to become more asymmetrical that problems start to occur, and Garage54 keeps cutting at the rims until there is only one spoke left on each.The conclusion? Its amazing what kind of forces the single spoke of an alloy car wheel can take when put under some pretty extreme stresses. Eventually, all the wheels are destroyed, but, surprisingly, they lasted a pretty long time. Obviously, absent the aforementioned charts and diagrams, we cant really go into the details of the forces acting upon any part of the wheels at a given point.But its safe to say the video is entertaining and that maybe you can afford to get away with a couple fewer spokes on your

EVs need paying and charging conformity, says top charger maker

The adoption of common charging and payment standards is a vital step towards the widespread take-up of EVs, according to one of the biggest makers of charging points.  Swiss-based technology firm ABB supplies equipment to a number of charging networks worldwide, including Ionity, which recently opened its first 350kW rapid-charging station in the UK.  Tarak Mehta, the boss of ABB’s electrification division, said working towards common charging standards is “a role we take very seriously”.  Mehta said that although he understands the reasons for car firms wanting to gain an edge with their own systems and infrastructure projects, this complicates the situation. “With the nature of politics, the way the automotive OEMs (original equipment manufacturers) feel about themselves lends itself to not having too many common standards,” said Mehta. “The infrastructure is proportional to the (number of) standards, so one standard versus two has a substantial impact on the cost of infrastructure you need in any one geography.  “On the commercial vehicle side, we see a far more collaborative evolution. On the automotive side, let’s put it this way: it’s a bit more challenging. The good news is that, so far, in any one geography, we’re down to one or two standards, and that’s probably good enough.”  Although there has been a move towards a common charging plug design, EV owners still face the need to sign up with several companies in order to use a variety of charging points.  “The biggest issue (on the payment side) is data,” said Mehta. “Convergence could happen very quickly if there was an agreed data-sharing model, because a lot of data that comes with EV charging has value. Getting that data shared is a bigger issue than getting credit cards working (across different accounts) and having it standardised might take some regulatory
