I saw that on TV the other night. I was getting annoyed at the beginning, but then they got it together on the EV front. I was also surprised that they mentioned Aquion based in Pittsburgh.
I still can't tell if Nova's Koch funding has any effect on the content or if it's just a red herring.

I did peruse Aquion's site and noted that they have a distributor network with one here in Arizona. The product looks quite small in comparison to lead acid batteries and appears cheaper than say a powerwall (but this needs to be confirmed). I sent an inquiry to the AZ distributor about a home configuration. We'll see.
Here's their distributor link: http://aquionenergy.com/distributors/find-distributor/

Here's the roadmap for what's needed.

That would certainly be nice to see happen.
Even though our i-MiEVs are a quantum leap ahead in energy efficiency over gas-powered cars, electric bicycles are 10-20 times more electrically efficient (achieving 35-80 miles/kWh compared to our 3.5-4 miles/kWh). I went on a group ride yesterday around Pittsburgh. For 7 bikes to travel 20 miles, total electricity consumption was about 2.5 kWh. While true that most of us were pedaling (one wasn't, I was more or less just spinning the pedals), we all ended with nearly the same charge level. To compare, 2.5 kWh would power:
1. A Ford Focus (35 MPG) for 2.4 miles,
2. An i-MiEV for 10 miles,
3. An eBike for 140 miles.
For my 23 mile commute, the 6 kWh my i-MiEV uses on average in one day would power my commute for 10 days on the bike. Even if four people were in the car, we'd still be better off on four bikes.I guess what I'm trying to say is that even though electric cars are a considerable jump in energy efficiency over ICEVs, they are definitely not enough.

PV1, it's wonderful to see the thousands of bicycles in use in, for example, Copenhagen. Bicycles, complemented by electric bicycles, as slowly making inroads into our culture.
In the big picture, there are two considerations -
1. Emissions
2. Energy efficiency
If energy generation can become emissions-free, then efficiency, while laudable, becomes less of a consideration. For example, almost all of my (inefficient) electric-car driving and home power consumption utilizes emissions-free energy. It's adverse emissions we need to curb … no, eliminate, and, as pointed out in the article, figure out how to reverse.
Here's the precursor article (to the one above) talking about 2degC:
http://www.vox.com/2014/4/22/5551004/two-degrees
Unchecked, we're heading for a 4.9degC rise by the end of this century. Terrible legacy we're leaving the next generations, especially when knowing what needs to be done NOW to prevent that. Don't get me going on the absence of political will to do that.
Sadly, a significant percentage of the population still denies that we are facing a crisis.

I've seen some of the videos of Copenhagen at rush-hour, and if those were cars, it would be an endless parking lot (funny, but sad).
While it's true that energy efficiency is less important with clean power, It can make a huge dent in emissions in the meantime. A perfect example of that is the transition into LED lightbulbs. Currently, not only do they reduce emissions, they make off grid solar installs much more effective and cheaper. Even for folks like us that have grid-tied solar power, better energy efficiency allows more of that solar power to flow to the grid and offset dirty power.
Even with totally clean power, the much higher efficiency of an electric bicycle compared to a car would allow a single 100 W solar panel to power my transportation needs, compared to eight 275 W solar panels. While the environmental impact of manufacturing solar panels is fairly minimal, the more efficient our energy usage is, less generation equipment is required, further saving energy and resources.

Looks like this thread has evolved into solutions rather than scaring us to death...
They're addressing their FlashBattery being able to quickly absorb a high power jolt, but the allied issue with EV rapid charging is having a very-high energy source available and then being able to dump it quickly into the vehicle without blowing up the source or connection between the two. Last night I spent quite a few hours freezing way up in the remote Sierras at an RV campground resetting their (expletive deleted) 50A circuit breaker which was popping open as I was trying to charge Tesia (my Tesla) … I had to dial the current waaay down… 32A finally held. :twisted: These FlashBattery people are talking transferring energy at thousands of amps.
Rapid charging is only needed when doing an extended and continuous trip (like Rick on Route 66), whereas ordinary L1 and L2 normally meets most people's needs; that said, this would be really useful technology for the commercial industry, especially long-distance truckers.
As far as this FlashBattery is concerned, to paraphrase Elon, "bring me a fully-developed production-ready battery to test, and then we'll talk".
Clueless marketeers, using the soundtrack of an ICE vehicle as the BEV starts and drives off at the 00:40sec mark. Doesn't every BEV driver now just cringe when hearing an ICE car start?Phximiev said:
