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? https://play.google.com/store/apps/details?id=com.otsys.notifier&hl=en 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.
Actually it looks more compact than conventional overhead cams.
"pick their own gears" is a great idea! So the buyer can choose an economy/quiet 6th gear and just downshift when needed. The torque looks good enough that it may do well with a big overdrive. What is the MPG? This car looks very practical, fast, and probably very good MPG.
Low profile tires end up having much more rotating inertia (bad), wasting fuel in stop and go driving. Maybe they also have more drag with a more squared shoulder. Look at top level race cars, none have very low profile tires.
The aero wheels might look better with different paint options, like all black, or all metallic.
I wonder if the break-in period, which can be long, still reduces the MPG.
Will this lower mercury content as well?
What about mercury from bunker fuel?
That would be such a waste to replace the well engineered wheels with guzzler wheels.
What is the cause of the worst pollution in Southern California, that is not also in the Los Angeles area?
I wonder how much the SOFC unit will cost. Unless I get my electricity usage down 80%, I am paying ~$0.32/kWh, $200-250 per month. It looks like it should cost no more than a few thousand $. But not good for GHG. I would rather go with PV which looks to be maybe getting very cheap thanks to recent developments. SOFC combined with electric motors is really a good replacement for ICE and liquid fuels, with much lower GHG and no range issue. Big trucks would be an ideal application. Maybe add thermoelectrics to get more efficiency. Seems like the SOFC durability is really just an engineering challenge.
Fuel consumption is highly dependent on vehicle choice. Fuel tax is enough in UK to give incentive to buy smart. Mandating overly sedate highway speeds is a drag on the economy.
Actually the 500 kJ limit is very useful if the charging/discharging rate can be high enough. It equates to 810 hp for 1 second.
