This article is more of what's needed- a holistic view that looks at tradeoffs.  The non-technical public needs to be better informed as well.

Good example is the Nissan Leaf...it claims "Zero Emissions" on an emblem or as a great big decal down each side.  All of us know that's blatantly false but I'm sure most owners truly believe they are not creating any emissions anywhere.  (I'm surprised some attorney hasn't taken this up as a "hobby case"!)

I've wondered what pollution issues the manufacturing and disposal of photovoltaics  create?  Something to investigate when I have more time.  Hopefully it's minor.

I'm not anti-EV, they have their niche.

Tesla has stated that recycled batteries can be used for grid storage and other purposes.  The aged batteries will only hold 80% of their charge but this is fine for other applications.

As a long term hybrid driver (Honda Civic Hybrid with over 100,000 miles at 49.2 mpg), I believe that the EV and hybrid vehicles serve as testbeds for many technologies that can benefit us all.  I'm still running on my original brakes (50% front and 90% rear still remain) because my braking energy is recovered in the battery rather than being worn off my brake pads. My engine turns off at stop lights whereas the SUVs behind me burn gas even when they're not moving. Early adopters may pay a little more to drive exotic vehicles, but the lessons learned should benefit us all as they are deployed across the next generation of vehicles.

Yes, that would be a nice PhD, I would had done it myself if I had the time...anyone conducts a research like this pls email your dissertion! ;-)

Kris, wow, you are definitely taking this whole concept to another level -- in terms of the entire food chain in the ecology. Would be a nice project for some PhDs, huh?

The article doesn't mention the obvious, the most green car is just no car...just walk or bike...although one can argue that you needs to eat more due to extra physical activity and consume some extra calories resulting in extra emissiono of green gas (especially if you are eating meat, see methane release by cows)...I wonder whether has anyone done this type analysis, would love to see you it...Kris

So it is the combination of Solar energy, Fuel cell and the batteries that can make a long range , non polluting and economical EV. Right?

If offices provide solar charging facilities  at the parking stations and the highway gas stations provide the Fuel cells on rent then EVs can be a very attractive proposition.

Another way of having a fully charged battery on the go is to have battery exchange stations on freeways where one could exchange the discharged battery replaced by a fully charged battery in a jiffy.

Also air conditioning, which is most needed when the sun is blazing away.

A good long-term solution IMO is solar-generated hydrogen for fuel cells.  You can make the hydrogen while the sun shines and convert it back to electricity whenever you want.  Renting a fuel cell for long trips might be a dandy way to extend EV range.

@GogoGeek - good point.  I have never understood this.   The big disadvantage of solar is that it is only available during the day.   And what are a good percentage of vehicles doing during the day?  Sitting in parking lots while their owners work.  Ideal marriage - use solar to charge EVs during the day.  EVs are the answer that Solar power has been waiting for.

I don't mean to sound fervently anti-nuclear, though. My only point was that JUST BECAUSE some technology might represent a theoretical "zero carbon footprint," it does not mean that there are no big or even huge costs involved. These other costs cannot be ignored either, in the heat of the moment.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
