This is a very good approach! The OEM's tend to do the "expensive add-on packages" scam, as they would rather you crash and scrap your recent car, to sell you a new car. The negative incentive to not make these safety improvements standard, especially on EV's increases vehicle production emissions in the name of profits. Health, safety, and pollution are compromised. "Connected-vehicle technologies allow vehicles to relay important safety information to each other to avoid crashes" is long overdue. There should be an incentive structure to accelerate Connected-vehicle technologies.
Looks like the i-MiEV, which had terrible aerodynamics, maybe better going backwards. But at these speeds it may be a good tradeoff.
Blending the H2 tank into the wing would make a much more efficient design overall. All the appendages that are not bombs, refueling, or radars are starting to look ridiculous. Except if the H2 storage tech is evolving to fast. Great to see aviation decarbonization progress!
Wow, turning a dangerously abundant, powerful greenhouse gas into 2 useful high value products, like killing 3 or 4 birds with one stone!
Kudos to those who discovered this! It's great for aviation, heavy duty small trucks, long haul trucks, ... Most EV's don't need H2, and will not use it until the cost gets competitive in at least 10 or 20 years. Perhaps EV's can use this H2 tech sooner with a rentable self powered trailer that is controlled via an OBD dongle.
Maybe good for some small niche, but it's best not to make CO2 and then spend money to sequester it. Law of Entropy!
Perhaps the technical risks have been reduced enough that it's worth accelerating to start manufacturing for grid storage and EV ASAP! Seems like a huge cost improvement.
Seems like hybrids with 15-25 kwh and a really small, simple, cheap ICE with direct drive for highway only would be a best cost balance. 1.5kwh is only $150-$250 worth of battery to power a much more expensive e-motor, and only cover very limited range. 15-25 kwh would cover 90% or more of mileage.
These linear extrapolation projections will probably be completely wrong in predicting the S curve disruption.
Seems good as the H2 heat of combustion is 286kJ/mol as compared to the endothermic cost (8.9 cal/mole = 0.037 kJ/mole), much less than 1%. Next research task here is figure out how to use this process to produce carbon fiber, and you have a huge new high value zero carbon emission alternative use. Ref:
Lot of those maybe not the latest longer range EVs. We drove my 1st EV, a 2012 Mitsubishi i-MiEV 12000 miles per year, much more than the 2nd car , a VW TDI, as it was so much cheaper to operate and maintain and was ideal for 99% of trips. Finally replaced them both with newer EV's. The "if an EV is the second car" is a good point. It would be good to look at how much % energy is save by all the low usage EV's. With the short around town trips, the EV's get 4X to 5X better MPGe on average.
For commercial aviation the Powerpaste 6X higher "fuel" weight will limit range to roughly 3000km unless speed is reduced and propfans are utilized, allowing perhaps 4000km range, but this is still much better than Lithium batteries. How much will it cost compared to other carbon neutral options?
Quick math estimate looks like about 200K chargers more needed to even it out nationwide.
How about using nuclear power thermal for high temperature natural gas inert gas pyrolysis into carbon fiber and hydrogen production
Tires with less toxic dust emissions would be nice.
I didn't read the whole 95 pages, but searching thru it could not find much mention of T&D Transmission and Distribution, zero mention of HVDC. Seems like an upper limit to storage needed without those considerations.
Between this and 100 kW is an ideal level for restaurants on interstate highways to offer free charging with validation. Much easier to integrate charging spots into any grid. Stop during your trip, go in and eat and activate your charging.
You can get 2-axis solar with very high utilization by building giant floating lily pads the rotate about vertical axis, and with each panel inclination controlled by pneumatic or water hydraulic control for horizonal axis control. Low cost 2-axis solar, free land, reduced evaporation, no curtailing, ...
SpaceX must use this for starship long range commercial passenger travel instead of dirty methane...
There is an old laser driven fusion concept that is looking promising with new lasers. The fusion energy directly produces electricity. Now imagine that the two are combined to create a "simple" air vehicle with incredible range and hypervelocity.
This is retarded. Coal is near perfectly sequestered Carbon. And then the carbon engineering scammers say it's cost effective to remove it from air defying the law of entropy. Rulled by idiots, human are doomed.
The Wright's engine tech can be used with hydrogen or ammonia derived power for long haul.
A standard measure of cost should be $ per kwh per cycle
Mandatory V2X in phones could accelerate adoption.
1 cylinder Rex with bigger battery would be better
