That is a gas powered van, but it's towing a battery, not a generator.

Another misleading meme, they are not popping up everywhere, they are being built in places where there is no access to electrical power.

And it does not take 3 hours to get 200 miles of range either in most EVs.

Memes are nearly always stupid.

Ok, but the fact that you have to install petrolium powered generators to power your electric car, kind of ruins the whole "save the plant" purpose of the EV. The point of the meme is to point out the absurdity of the whole EV trend. 

Look, I have no problem with EV's, I think they could be the future of personal transportation. But the infrastructure is not yet in place to support them no matter how much some people and politicians want it to be. California was having rolling blackouts long before EV's became a thing and with a slightly smaller population. Now there are over 600,000 EV's in that state representing a fraction of the total number of cars on the highway. And in 13 years, they hope to be almost fully EV, yet they are already having trouble keeping the lights on. 

As far as EV's being carbon neutural or emissions free, that is another lie being perpetuated by many. Just the mining of the rare earth minerals to build the batteries, consumes enough petrolium to power a ICE vehichle for a number of years. And then, once the batteries are worn out, they become a environmental hazard to dispose of.  Never mind the fact that we have to import those materials from places like China or Chinese controlled territories.

that's not a 350KW generator
probably 35KW

might use 1 gallon of fuel per hour

Yup.  The actual facts about EVs are important, they have tradeoffs, some pos some neg, like nearly everything in life.

The biased folks will present only one side.

1). The infrastructure is coming. Slowly, but surely. On the flip side of things, I can’t refuel my ICE vehicle at home. 

2). The disposal and recycling of batteries is in its infancy. I would guess that most large li-ion batteries would be recycled. Some can be repurposed. 

3). Agreed on the lithium mining industry, but it’s no dirtier than coal mining or some o&g production.

The problem with turning water into hydrogen and oxygen is thermodynamics.  That can't be "solved".

We had a lab once where we did it at room T.

I finally listened to the piece, it's 100% BS. 

I found another article which makes more sense:

Scientists Find a Simple Way to Produce Hydrogen From Water at Room Temperature : ScienceAlert

They developed a gallium-aluminum nanoparticle thing that splits the water.  You need aluminum for this to work and it is consumed in the process, or converted to Al2O3.  Then you have to reclaim the aluminumm which takes energy.  This is mildly entertaining but I don't see any plausible large scale utility.  I could generate lithium hydride and do the same thing.

I'm hoping for a breakthrough

I'm not hopeful, but hoping none the less

Using aluminum and water to make clean hydrogen fuel — when and where it’s needed | MIT News | Massachusetts Institute of Technology

This is a twist on old stuff, no breakthrough.  It takes energy to split water, no way around that, ever.

1. I can. However, most people cannot so they take the car to a gas station. The difference is that it takes about 5 mins to fill my truck and leave. It would take hours to fully charge a truck similar to mine (not that I can even buy a 3/4 ton EV truck), so taking it to a charging station is not practical. 

2. Yes it is. And that is only part of the problem, with the other being the price. A new battery for you EV with run well north of $10,000. For some, that is a significant outlay for a vehicle that they already own.

3. I won't disagee with you there execpt that we have coal and oil available in this country. We have to import the materials to produce EV batteries. And a majority of those imports are from China which has demonstrated that they are not very sympathetic to American issues.

The US could produce battery raw materials and is to an extent today.
