These are regular vehicles for everyday use, not sports cars where fully independent suspension has been around for a while and transversely mounted FWD cars with rear independent suspension are a recent innovation and save space. A car with independent suspension will perform better, but the point was about sprung weight, and a traditional rear axle has a lot. In many EVs there are transversely mounted rear motor(s), though with CV shafts driving the wheels.

I am talking about regular cars for daily use, like Honda Civics or small four-door VWs. It is a sufficiently contested customer space that a serious performance/safety/ride comfort ding that comes with multiplying the unsprung mass is really not an option. For pickups or delivery vans, perhaps different case. But for a passenger machine, there will be considerable loss of stability under transient loads, such as encountered in a panic avoidance maneuver. Reducing the safe performance envelope is a Bad Idea imo.

To summarize, I don’t think hub motors confer a benefit that buys back the detriment to the car’s road manners.

The engineers will fight it out.

That might be fun to watch.

One thing though (imo) that suggests that the engineers are not the shot-callers is the popularity of SUVs. They make engineering antisense: resource-hungrier in manufacture, less efficient to operate and less stable than proper cars, but the marketers love the things and their higher per-unit profit. People can be dumb.

Solar canal shades … sounds easy but

apnews.com

Solar panels on water canals seem like a no-brainer. So why aren't they widespread?

The idea of putting solar panels on top of the world's thousands of miles of irrigation canals has long seemed like a good one.

On the surface it seems like a good idea, saves water and cools panels while using wasted space. Perhaps leave some gaps between the panels to let some light through and to ease maintenance concerns. I see in CA they plan on using a saltwater redux flow battery for long term storage of the power generated.

People are waiting for better batteries and prices, many people who would buy an EV know what is coming in a few years since it's in the news. There should be some deals on EVs soon, buy cheap and put in a rebuilt battery pack in 5 years with even better range.

Thats me. Im commited to my next purchase being an EV, budget and needs being what they are I will be buy a vehical in the 4-7 year age range. The economey evs with suitable range are the volt and the leaf both ran fisrt generation 2012-2018 with 3rd gen set to be realsed in 24/25. I hope i can milk enough life out of my 2012 fit so i have a more robust market of suitable options when its time for my new car.

There is one ev charging station at my apartment complex of approximately 300 apartments. I have been living here 3 weeks and not one car have I ever seen charging . I never see ev cars here. Yet another town is the USA that has no interest in EV.

First it was too cold, and now it’s too hot. That Goldilocks is one picky (burst of static).

It's Too Hot For EVs To Work Right

We already knew electric vehicles don’t do so well when it gets really cold outside. Well, apparently they don’t really like extreme heat either. According to Automotive News, the recent heat wave across much of the Southern and Western U.S. has brought their range issue to the forefront.

theres tons of stuff to or that will save the enviroment, but it wuill taqke a new world order in order to get it done.
tezler had it right with electricity, not edison, edison was money orientated, tesler wanted to give it away foor free, so they cut him off from funds to compleat his endevour.
theres giant co2 scrubbers to fix the co2 problem.
the problem is money, where its to be made, it will be made at the planets expence and ours

Don’t even seem to have enough money to provide clean drinking water to people. Just read 2 articles about contaminated water in Helena-west Helena Arkansas and many small trailer parks in Colorado, including Aspen, where people have undrinkable water, some for years. No one wants to fix it for them. Many folks in the USA live in trailers because living in a trailer costs$600 a month compared to the average rent of $2,200 in an apartment complex or small house. Things are only going to get worse . And…no one talks about….about all the heat that is being caused by the artillery and weapons and bombing going on from the Ukraine war. That war needs to end Now. I will vote in a new President if they promise to stop that shit.

Arctic heat is coming our way. And fast!

6,243 views Jul 23, 2023
Arctic temperatures are rising at least three times faster than the global average. That's causing a whole raft of very unwanted consequences in our global climate system. Now a new research paper has analysed the fundamental long term changes in the way heat is carried into the Arctic Ocean from the much warmer Pacific and Atlantic oceans. And it's not great news!

it’ll be a lot less cool if it turns out that you need a megawatt-plus wondercharger to hit those marks, and pay $100 a charge.

Assuming a 200-kWh battery and “better than industry average” 5 miles per kWh, that’s still $70 a full charge from home, without paying the charging-station markup. I pay less to go a mile in my gasser, at $4.59(9) a gallon.

Dammit guys: the way forward is efficiency.
