There is quite a push from media on electric vehicles these days.
Most of the proponents are saying its the future, and ICE's (internal combustion engine) days are numbered. That we are going to see an exponential adoption curve, because, everyone wants an EV (electric vehicle). That the only cars in the future will be EVs.
They are assuming everything will remain as it is today:
- That people will live in cities
- That people will drive to work in congested traffic each day
- That people work in those cities.
If you assume these things, then yes, the EV is a wonderful solution. (but not the only one)
However, all of these assumptions are false.
People are leaving the cities for all kinds of reasons.
Mostly it is because the city exists only because of manufacturing.
Everything else in the city is to support that manufacturing.
And when the manufacturing leaves, everything else dries up.
Just like all those ghost towns of forming booming mining towns.
Further people are leaving the cities and suburbs because the quality of life is dropping.
And don't forget, if ever there is a disruption of food, water or electricity, then those cities become prisons fairly quickly, with everyone on death row. People who are survival minded are fleeing the cities too.
This results in the need, and usefulness of an EV dropping drastically.
The EV is great for around town. It sucks out in the rural areas. Almost all of its advantages turn into disadvantages.
Next is the point that people will continue to drive to work.
And we already know this isn't going to last. Not only are the jobs diminishing, the internet has made it possible to work from anywhere. This trend is growing faster than the hyped up curves for EV sales, and so, we will see fewer people driving to work.
Make America Great Again... well, the one thing that America was great at, was the great depression. And, we are about to hit an even greater depression.
In a depression car sales do not go up. And new technology, especially if it is more expensive, tends to have its adoption rates severely impacted.
Lastly, the EV is not a technology in and of itself. The Tesla was built out of book written in the 1970s. It has no new innovations except its flat screen.
When you consider the total emissions and pollution of creating the car, it is far less environmentally friendly than a gas guzzler. If just one magazine did an article about the Lithium mines, and how aweful the condition there are, EV sales would drop like a brick. But, fortunately that stuff is kept out of news.
And when you compare the EV with actual really innovative transport improvements, it is really lack lustre.
Things like running a multi-fuel turbine. Turbines are much more efficient, the problem has always been how to make a transmission that works with an engine that doesn't like changes in speed. But, if you pair up the turbine with a genset, and store the energy in supercapacitors, then we have a hybrid that is much more efficient than anything on the road today.
So, what is the real reason that EVs are being pushed right now?
Well, the same reason smart (dumb spying pieces of shit) appliances are being pushed.
Imagine a world where if you don't pay your license fee, you car doesn't go anywhere.
If you don't pay your traffic tickets, your car doesn't get charged.
And every time you plug your car in, the govern-cement knows exactly where you are.
It is the ultimate in control grid.
Further, since the EV is completely electronic, it is easy for a cop to send a kill signal.
Now you know why so many articles are coming out about how good EVs are.
Like global warming and "fossil fuel" electric vehicles are this weeks big scam aren't they...
I would agree that they are this week's big scam... but they are little ^_^

In fact pushing a vehicle with an electric motor does not require it to hook into the botnet. My grinder has an electric motor, yet hackers can't touch it.
Lithium enough to make the batteries necessary for us to have enough EVs does not exist on the planet, however, so EVs aren't going to suddenly replace infernal combustion engines until better batteries are available.
Pushing a vehicle with an electric motor, as you suggest can be done by using various chemical fuels and a turbine to create requisite charge to turn the motor, is simple and far less complex than ICE engines. This is hard to overestimate as a plus when it comes to durability, and decreased maintenance costs.
As 3D printing becomes more ubiquitous, I expect we'll see many more people rolling their own cars, and using hybrid systems to power them using chemical fuels to produce electricity onboard that powers electric motors. I am confident we'll see folks making their own PCBs and chips too, which is going to eliminate the factory backdoors that enable the panopticon.
Chips don't have to be superminiaturized, after all. Eniac was huge. While we can't print microscopic circuits (yet) we can certainly print simple circuits for our bespoke vehicles. They only need to be small enough to fit in the structure of the vehicle. Cars are pretty big, and there's room enough for a lot of printed circuits incorporated into the structural components.
Thanks!
Yep, it does not have to, but all the "smart" vehicles that Fjord and Doy-ota sell do.
Did you see the college kids that took over a car and caused it to steer into a ditch, just using the radio? Scary!
I would really like to see garage built cars.
One of my ideas is a 1000 cars in a 1000 garages.
Each garage building a machine that produces a single part, and then swapping with 999 of your closest friends, and viola. Cars.
I am thinking about plans for a tesla turbine powered generator.
If it works, than it would be the simplest build, simplest maintenance.
Dunno if you've come across this by @corbettreport:
I have probably watched it.
Technology is not Corbett's forte, so he is not my number one source.
I mostly talk to engineers who wonder what happened in the 70s.
Not exactly.
A capacitor charged to a million volts lost weight.
Bigger and better stacks, at higher voltages, floated.
A supercapacitor, as the term is used in the industry are actually very low voltage with a very high (for a capacitor) power storage. Capacitors are also usually spiral wound and so they will not float, even if they could somehow withstand the ultra-high voltage.
I am no good at links and even worse at names.
I will try to find them, and then write a post about them.
Then, if i can find it later on steemit, i will have a reference.
... right?
The problem with compressed air is that energy storage is tiny. Pretty much like batteries in an electric vehicle.
So, you have a large, heavy tank, that doesn't take you very far (compared to gasoline)
However, they have been using it to power buses around cities.
And, just like battery charges, compressed air is not a renewable, it is a storage media. The energy is made somewhere else, somehow else.
