Amazing. Anyone has an idea what kind of bearings used in the wheels? The if you would spin its wheel, it would not stop spinning for almost 2 miles, whatever that actually means, makes it sound like they are something special.
Also somewhat funny how such competitions are usually sponsored by fossil fuel companies. It's like they are preparing for the future with a business model idea like 'so, within x years there's going to be not enough fuel for the cars. Prices will skyrocket. Hmm, better make some cars that don't use a lot of fuel so we can stretch it to the fullest'. Perfectly understandable from an economic point of view, but would't research into alternative, cleaner mobility a better solution for everyone in the long run?
- Loughla 12y agoCorrect me if I'm wrong, but isn't moving the same distance using less fuel cleaner?
- TylerE 12y agoDepends. If you have to build a new car to do it, the answer is almost certainly no.
- smoyer 12y agoNot always ... the emissions of a push mower are dramatically higher than automobile emissions (on a per horsepower basis).
- saalweachter 12y agoIt's probably better than where we are (assuming, as someone else pointed out, emissions standards aren't reduced). I think the point being made was more about local minimums versus global. The most optimized ICE car possible will be impressive, but the emissions will never beat electric (assuming clean electric sources, obviously), and the rolling resistance will probably never beat trains or canals (which are of course only useful for arterials, and possibly only freight).
- hengheng 12y agoCup and cone bearings are about the best you can get with some manual fine tuning. If you carefully hone the surfaces with wax and toothpaste, and then select the beads running between the two halves of the bearing to have almost equal size, you're already good enough for track cycling championships. Regarding the sponsoring by Shell, I doubt Shell cares. They are paying for this with pocket money, and they get some greenwashing in return. Doesn't sound bad.
