[Greenbuilding] Opinions on electric plug-in cars - time for atomic batteries?

Steve: "less well-understood" by whom? We sent the Voyager deep space probes out of the solar system -- well beyond the range of their solar cells; and their atomic batteries kept on tickin'. Even if we were allowed to develop afffordable, safe & reliable atomic battery the budding oil cartel would have blocked it. They were used to power pacemakers in thousands of people; so why not cars we naively thought. long before OPEC was created?

I NEVER said hydrogen or electric cars were safer.  I do think danger from nuclear batteries are less well-understood.---- Steve (KZ6LSD)

Steve: You think it's safer to crash electric- or hydrogen-power cars? Did you know Russia has developed a new “top-secret” submarine, possibly using advanced RTG's, according to: 
"Russia: A new development in naval propulsion." (Kuwait Times Website, September 13, 2007)
   
 What do you think are used to help power nuclear subs, remote lighthouses & beacons, etc? If you Google "atomic battery" you get lots of hits and this summary:
The terms atomic battery, nuclear battery, tritium 
battery and radioisotope generator [RTG] are used to describe a device 
which uses the emissions from a radioactive isotope to generate electricity. Like nuclear reactors they 
generate electricity from atomic energy, but differ in that they do not use a chain 
reaction. Compared to other batteries they are very costly, but have 
extremely long life and high energy density, and so they are mainly used as 
power sources for equipment that must operate unattended for long periods of 
time, such as spacecraft and automated scientific 
stations in remote parts of the world.Carmine

"Atomic Battieries"?  AFAIK I know those fancy batteries in satellites are powered by highly radioactive isotopes of strontium, etc.  Many years ago, one came down in northern canada and spewed radioactive wastes.  Spread over a wide area lowers the radiation risks to a non-issue but imagine a car accident in an urban area.....

Tedd: Have you checked out the EPA-certified performance of  the Chevy Volt? ("Chevy Volt", IEEE Spectrum, April 2011, pp. 36-7)
   If we ignore source energy, the EPA estimates the Volt returns the equivalent of 93 mpg and will cost US $1.50 to drive 40 miles with electricity costing 12 cents/kWh.


   How the volt will cut Greenhouse Gas emissions, the EPA doesn't say?
   Four decades ago, compact versions of atomic batteries like those used in Sputnik & Voyager were supposed to help us from gassing ourselves with CO2 & NOX.


   What happened?
