And another fuel-cell breakthrough claim.

In regards to my previous post https://endless-sphere.com/forums/viewtopic.php?f=7&t=89002&start=5850#p1564705 I think folks are going to be surprised how far and deep Hydrogen Fuel-Cell technology weeds its way into everyday life, but I think the home car will be one of the last spots it will come.
Check out this all in one fuel-cell home energy station, forget about Elon Musk's crappy 13.5 kWh, this one can store 1.5MegaWh of electricity. That's 1500KWh.
It contains a battery, electrolyzer and fuel cell all working together for a self-sufficient and customizable house energy system.
It makes use of the Hydrogen fuel-cell waste heat for heating the home water and heating the house for winter/cold nights increasing overall efficiency.
In addition, the waste heat generated during the operation of Picea is provided to the house as heating or hot water, thus further reducing your energy bill.

I constantly see the Victorian government funding drone usage for every type of usage imaginable, including finding injured koalas etc.
This one is distributing seeds for bush areas destroyed by fire.

Police buy 50 drones.

Again, I can't help but imagine a large amount of the running cost is having to swap batteries over every 25minutes, these are government jobs where a lot of time is spend in downtime of the drone.
So again I can't help but see the extra cost of Fuel-Cell drones negligible to in fact being a long term money saver.

Looking at 15 of these EVTOL flying cars out there, only 3-4 are going to use hydrogen fuel-cells.

It's now been 41years since Lithium-ion battery chemistry we use today were discovered, I think the folks designing these EVTOLs are foolishly optimistic that some new breakthrough will occur.
https://en.wikipedia.org/wiki/Lithium-ion_battery#Development
1979 – Working in separate groups, Ned A. Godshall et al., and, shortly thereafter, John B. Goodenough (Oxford University) and Koichi Mizushima (Tokyo University), demonstrated a rechargeable lithium cell with voltage in the 4 V range using lithium cobalt dioxide (LiCoO2) as the positive electrode and lithium metal as the negative electrode.
This innovation provided the positive electrode material that enabled early commercial lithium batteries. LiCoO2 enabled novel rechargeable battery systems. Godshall et al. further identified the similar value of ternary compound lithium-transition metal-oxides such as the spinel LiMn2O4, Li2MnO3, LiMnO2, LiFeO2, LiFe5O8, and LiFe5O4
13years of lithium battery breakthrough promises and they have all turned out to be baloney.
