Sorry, basic thermodynamics says this can only reduce the overall vehicle efficiency, and the tires additional energy to power the system will be more than they harvest. So this article is misleading. TPMS only needs a tiny battery. However it could be useful to power a pump in a tire.
Seems the six-speed automatic transmission is a dead weight in the i8. The transmission-less Koenigsegg Regera is the way of the future.
"Use the reaction water for cooling" after storing it and letting it cool, or cooling... (lots of options) The scooter FC power pak would make a great range extender for EV's. FCEV's should be based on the smallest cheapest H2 FC just for range extending. Make it like a generator with a standard power connector for all EV's.
With an excess of cheap electricity, this would be ideal to replace the carbon based fuels used in long haul trucks. But to really compete with BEV's the round-trip efficiency will have to be improved. Of coarse a huge investment in cost competitive H supply and associated electricity is needed. Seems more likely to be a niche product.
An interesting and worthwhile concept to explore in chassis design. Seems combining with all electric power would maximize the advantage. Otherwise go the koenigsegg regera route. I would like to see a comparison of this concept versus the opposite layout like the t-rex motorcycle.
I really like my Mitsubishi electric car but this technology is not for and earth application. The problem is diffusion in atmosphere will lead to radiation leakage. To be viable for power transmission, power will be much higher than communications signals. So even a small 1% leakage will be very polluting, but acceptable for business. I oppose all wireless power that has potential to leak energy at higher levels than existing communications emissions. Many people choose not to live next to high power lines, so that should not be considered an acceptable level. Maybe in space this has some niche when launch costs become trivial or solar cell manufacturing is done in space.
It probably has a catalyst. Most motorcycles sold in California have them now.
This most likely has no future for short and medium range light passenger vehicles. Vastly improved battery technology soon to be available will cement EV's technology lead even more. However this may be an ideal environmental solution to long range large truck and train transportation.
Why don't they cut the length of the internals, shaft etc. and use multiple sections stacked, and offset by some angle to smooth out the torque ripple. Just like more cylinders in an ICE is used primarily to smooth out torque. This is even more critical to have smooth torque in electric motors to take advantage of the zero RPM capability.
SCE has a ripoff EV plan that does not really save any money because day rates are so much higher. Is PG&E any better? The real reason this is happening is providing power to charging EV's is so profitable. Selling kWh for roughly 5 to 10 times production cost, and the more you sell the lower the delivery cost. $0.20/kWh is equivalent to $7/gallon of gasoline. EV's are so efficient that it's accepted. But this is really not encouraging EV's and zero emissions unless you go solar, not possible for everyone. The ICE fuel business has so much smaller profit margins due to competition.
DavidJ, it's a pure mechanical flywheel KERS. Another advantage of this design is it allows maximum kinetic energy recover during braking. The front brakes could be downsized a lot. In contrast, F1's current rules greatly limit braking energy recover by the KERS.
I would like to see how it works. Stiff springs and traction control will make it easy to manage weight transfer. I see the advantage here. Aerodynamic center of the more efficient under body ground effect wants to be forward. Chassis have become super lightweight while the rest has become heavier. So a rear wheel drive design suffers from excessive rear CG unless a draggy rear wing is added. So this could be more efficient aerodynamically. The other big issue is will this have good stability, i.e. no possibility of flipping... Why not use rear electric motors?
The technology from this will trickle down, especially to high performance cars. Funny how they always show the picture with the fake exhaust layout.
This would be good to make carbon free H2 to replace home natural gas.
Totally agree with Smil. Obese ICE cars should be taxed extra to provide incentive to light weighting. Ford did a good step with the Aluminum trucks. EV's and HEV should be less taxed proportional to MPG. There should also be mandatory higher insurance coverage for other persons injuries in accidents. Airlines should also charge extra for obese. Why should a little kids airfare subsidize...
I like the idea of self driving cars, except if they drive too slow due to programmed lack of confidence.
The reduced mass of 12V Lithium Ion could save more than lead. If 12V Lithium Ion became mass market the cost would be reasonable since less overcapacity is needed. The question is how much over sizing is needed for 12V Lithium Ion in cold weather.
Wiring up home EV charging is so much easier and cheaper. EV's are also so much simpler. The revolutionary battery tech will make EV's the way to go before HV's. The Mirai looks equally expensive and complicated to a ICE car. Long term, H range extender's might be worthwhile.
Is this related to the submetering pilot program in California.
Perfect direct drive EV range extender, allowing 4wd. Connect it to the wheels with a simple clutch single speed gearbox with ratio optimized for highway driving. The turbo is not needed, but might be better for emissions and extra power.
Top reasons for this: Always hitting red lights - Need more micro hybrids, or full hybrids to recover energy. How many years before everyone can use the EnLighten App to avoid burning fuel and brakes? Winter warm up losses. Lots of new ways to improve are coming to market. More weight in car in real world versus testing? Low tire pressure? Make TPMS mandatory. Front end alignment degradation. Engine degradation.
"five stronger than steel wheels they replace" is most likely engineering dumbed down to marketing. What was lost in translation is the critical failure mode, buckling, is easily increased by 5 times because the alloy is 3 times lighter and so generally needs to be 3 times thicker. Steel wheels are likely buckling critical, whereas alloy wheels are likely fatigue or fracture critical.
You forgot to mention reducing driver stress, fatigue and other negatives of driving in congested traffic...
So what about the other 20% loss EM energy? How do you prove it is safe to be nearby? Until now most EM is much lower power comm.
The video and narration is good. Take a look at it. The added cost could be offset by downsizing to fewer cylinders and better MPG from efficiency and a lighter engine and vehicle.
