New electric developments

"all of them had to be parked to cool off after the test drive", New take on "over-heating"

 

One motor-group (club ish) is gluing fins onto oil-pans & filters. Seems to be for towing/going up steep hills, & they say it Works.

 

Trolley buses should have been used in Sydney !.

Spacey, you can purchase aftermarket alloy diff housing covers, and transmission pans, with fins cast into them. In the case of the Ford 6R80 transmission, you can purchase a deeper aftermarket oil pan with fins, that holds an additional 3 quarts (2.8L), which reduces transmission operating temperature, not only via the fins, but via the additional oil capacity, as oil does as much cooling as it does lubrication.

Another fantasy. Car race tracks are still in existence because we built safety fences and catch fences to protect spectators from flying debris.

 

Flying above a race car circuit would certainly provide a ready-made venue with parking, seating, eating, toilets etc, but there's no way the aircraft could race above them safely. In some cases there may be tracks where the aircraft could fly outside the circuit so centrifugal force threw any failed aircraft outwards into open land.

 

Electric RC competition aircraft are sensational to watch because they are so fast, and slot cars were like lightning, so there's no doubt spectacular speeds could be achieved with powerful motors and short races.

 Make for interesting collisions at some stage. Well we do have plenty of oil tankers on the road but I try to keep well away from them.  nev

Batteries in EV's pose no more fire threat than perforated petrol tanks.

 

The vehicle designers smartened up their act probably 3 decades ago, in relation to improving fuel tank protection, after quite a number of lawsuits related to fuel tank fires, caused by poor placement of fuel tanks, and inadequate tank protections.

 

The same design criteria are applied to battery placement in the EV's, it is well protected, and will only get badly damaged in the very worst of high speed major collisions with solid objects, or head-on collisions.

Yes, It's of similar magnitude but the anti electric mob will seize on it when it happens. It will be like a miniature  atomic meltdown rather than an oxygen fueled "normal" type event with flames over a largish area. Nev

Just a note !.

 

" Batteries in EV's pose no more fire threat than perforated petrol tanks."

 

Race car's run alcohol, not ethanol/petrol like road users.

EVs don't pose any higher risk than ICE cars in that respect, but they need a new breakthrough in battery technology to avoid thermal runaway, where there have not been just a few, but many spectacular fires from EVs already. Unless they can can get a battery design breakthrough there will inevitably be design rules in reaction to the fires.

 

Same reason we're seeing the current pause in autonomous car development until computer capacity can be found to avoid all types of collisions, not just the most obvious - crashing into the car in front etc.

I mentioned on another thread… I expect there will be YouTube’s galore after Aero 25 at Friedrichshafen next week that feature all kinds of electric and possibly hydrogen aircraft innovations. I’m looking forward to see how good they could be and what the critical limitations are.

[onetrack]

Some Chinese ones are still in the "testing" phase, obviously. Maybe someone crossed up the wiring?

Imagine taking a very good and useful aircraft like a Beech Kingair 350 or Cessna SkyCourier and adding batteries and motors to "help" the PT6 engines, the result would be a dog.

Electra’s hybrid-electric aircraft is turning heads in the aviation world—not with flashy designs, but with its quiet performance and impressive flexibility. Capable of lifting off at just 35 mph and needing less runway than a soccer field, this short takeoff and landing (STOL) aircraft combines the practicality of traditional planes with some of the access advantages of vertical takeoff designs.

 

While eVTOLs have dominated headlines, Electra has quietly racked up over $9 billion in pre-orders for its eSTOL aircraft—outpacing even the most hyped electric air taxis. The secret? A conventional fixed-wing design with eight electric propellers along the wing and “blown lift” tech that allows incredibly short takeoffs and landings. And it’s quiet, too—flying overhead at 500 ft, it produces just 55 decibels, about as loud as a normal conversation.

 

Still in testing, Electra’s EL2 prototype has already shown promising results, with takeoffs in under 150 feet and airspeeds as low as 25 mph. A full-scale, nine-seat demonstrator is scheduled to fly in 2026, with certification expected by 2028. For operators seeking versatility without the complexity of eVTOLs, Electra’s offering is becoming hard to ignore.
