Personally, I prefer the free floating piston design (FKLG) from Fraunhofer because its ideally suited for a serial hybrid drive with an overall efficiency over 50%. No connecting rods and no crankshaft just "gas springs" at each end; it runs on H2 and is also adaptable to various fossil fuels.

Back in 1975, during the second oil crisis, I'd suggested a serial hybrid and was scoffed and ridiculed and was informed that something like that would never work.

I've been driving different BEVs for several years; the worst of those was the Leaf. Presently )'m driving a BEV with a range of ca. 300 miles in the summer. That leaves me about 200 miles in the winter and suits me just fine. I've never fast-charged any of my BEVs because presently no battery on the market is compatible to fast-charging without detrimental depreciation. I've never experienced range problems, not even with the lousy Leaf.
Considering my age, I'm what you would probably call an "old geezer" and I do have a mind of my own. Personally, I need a PHEV as direly as I need a hole in my head.

Facts that speak against PHEVs are the following:
a) Lugging around all that extra needless mass of the ICE while in E-mode increases energy consumption.
b) The ICE reduces otherwise available space and complicates distribution of available space.
c) Increases the overall size of the vehicle.
d) When in ICE mode, operational pollution continues.
e) Preventive and corrective maintenance of the ICE is rather expensive.
f) Overall pollution of the complete fossil cycle continues.
g) Hampers the development of better battery cells and improvement of our environment etc. etc..

Employing renewable energy to produce H2 via electrolysis has an extremely low overall efficiency and subsequently, is a pure waste of energy. It is highly recommendable to use that energy for a far more efficient process e. g. charging a battery. If it must be H2, then produce it without wasting precious energy; e. g.

For many US-Americans (too many) the world begins and ends at the continental borders of the US. Most are unaware of the fact that when referring to America most people worldwide relate that expression to the two continents constituting America namely, North- and South America. The US is located on the North American continent together with Canada. The US is a part of the NA-continent and is not America itself. Using the term America when meaning the US is a sign of over-boarding and exaggerated confidence not meant to imply a certain arrogance. Electrify America is a great slogan but for the present it would suffice to limit that to "Electrify the US".
Electrify America increases access to solar-powered EV charging for rural Californians with 30 stations
Electrify America, the nation’s largest public ultra-fast charging network, has added 30 solar-powered electric vehicle (EV) charging stations with two Level 2 chargers each to its network in the state of California. The off-grid, standalone chargers are strategically located throughout the C...
A battery-cell with a high energy density implicates a massive shift on the atomic level. Ions being shuttled back an forth whilst charging and discharging constitute such a shift. The contraction and expansion rate of silicon electrodes is inherently high. Subsequently, an electrode capable of high energy density compounds the expansion / contraction rate. This inherent attribute of silicon renders it insufficient as an electrode despite it's attractive energy density potential.
JAIST team investigates how self-repairing polymer can improve durability of silicon anodes
Although silicon anodes could greatly boost the capacity of Li-ion batteries, their performance rapidly degrades with use. Polymeric coatings can help solve this problem, but very few studies have explored the underlying mechanisms. Now, researchers from Japan Advanced Institute of Science and ...
@ Paroway:
Well, Tesla is in a completely different boat. They have the great advantage that they're not confronted with the task of transitioning from ICE-vehicle production to EVs; that switch is a considerable disadvantage for conventional MFRCs. Besides that, Tesla's existence is not sponsored from welfare and moral obligations / philosophies. They burned millions of dollars until they finally started to reach profitable levels.

I'm convinced that, generally, the high price of EVs is not based solely on the relative high price of a battery.
Car MFRCs have a low margin of profit on conventional ICE vehicles. Their (blind) profits are based on spare parts and maintenance philosophy. In comparison, an EV has very low maintenance and subsequently lacks those avenues of profit. I can't imagine that any MFRC would be satisfied with these inevitable results. One way to "iron that out" would be to slap those missing profits right unto the sales price and that makes EVs really expensive.

That's common procedure on aircraft carriers; they just don't use cables. On an airfield, linear 3-P e-motors - fed from the grid (via a buffer) - could be used for initial acceleration.

Sorry to disagree with you but the term as used is quite correct. Part of the energy invested to accelerate the vehicle induces potential energy in the vehicle mass. Recovery of such potential energy via an appropriate "braking mode" certainly is recuperation.
Mercedes-Benz introduces the EQA: entry-level to the electric EQ vehicle family
Mercedes-Benz has introduced the EQA, the new entry-level model to the all-electric world of Mercedes-EQ vehicles. The EQA is the first all-electric member of the compact car vehicle from Mercedes-Benz. A close relation of the GLA, it delivers all the characteristics of that vehicle, combined i...
"Researchers found that installing charging stations on residential streets, rather than just in central locations such as shopping malls ...."
Presently, residential streets are clogged up sufficiently with "lantern parkers"; this kind of solution would encourage ever more so and hence, impede local traffic. Not so good.

I have the impression that most EV builders are building cars for the race track and not for every day usage on the road. I'm convinced that a vehicle with two motors at 50 to 60 kW each, suited for AWD, with an acceleration time of 0 - 60mph in 10 sec. or slightly below, would do just fine. At any rate, I place more emphasis on range than acceleration.
