Electric vehicles

After reading about a Victorian(?) politician who became part of a company called Better Place which is seeking to develop marketable electric cars and most importantly electric car "re-fuelling" stations, I checked out their website www.betterplace.com and signed the petition to show market support for the idea.
I sent that link to a bunch of people and one mentioned the AEVA (Australian Electric Vehicle Association) www.aeva.asn.au
It's great to see how many people have made the effort to convert a car themselves (also check out worldwide conversions www.evalbum.com )
The Garnaut report apparently says that electric vehicles are not significantly more energy/carbon efficient than petrol vehicles. However, this is based on the power coming from coal fired power stations via the national grid. As soon as you get it from renewable source (your own roof top solar/wind, or via suppliers such as Jackgreen 100%, then it's all clean driving.

So, I'm heading down the path of doing a conversion. Information and even parts are quite readily available but the hardest thing is deciding what vehicle to convert!

Options
1) Small, old, cheap car that will be cheap to buy and run (but will have a pretty ordinary interior, possible other mechanical failings and doesn't do anything to promote/sell electric as an attractive option)
2) Small, newer car that's cheap to run and is in reasonable condition (but again doesn't really promote electric as an option to the current market)
3) Light commercial vehicle, newish, more acceptable to current market (but more costly to convert)

I'm favouring 3 as my best chance to help change the world in some comfort and style but I'll need to first set my wants and needs in specifications and project parameters.
*Minimum travel per charge
*Charge time
*Conversion cost including:
-vehicle
-motor
-battery pack
-controllers
-vehicle mods
*Vehicle surplus capacity#
* Vehicle body style


# - Electric conversions can weigh more than the engine etc that they replace, so smaller cars with less spare GVM (gross vehicle mass) capacity can result in the car going over the legal GVM (such as www.mightyboyev.com ). So a bigger car, while needing more power, can actually be a better choice to be able to carry more than just the passengers.

Vehicles and powers sources

So following on the ethanol fuel question.

I'm currently of the opinion that the capitalist way that ethanol fuels are being developed and managed is a BAD thing.
Pros
* Short CO2 lifecycle (plants grow taking CO2 out of air, we burn fuel putting it back in)

Cons
* Food crops are being diverted to ethanol production due to simple market economics and as a result it is contributing to world food shortages. (Fuel producers and car drivers are paying more.)
* Forests are being cleared to produce the ethanol sources.
* Ethanol is borderline on energy efficiency (ie: net energy in is sometimes greater than net energy out, mostly depending on fuel source)


As a tip, if you buy E10 or whatever fuel due to cost, be aware that;
1) not all cars can handle ethanol due to gumming up the jets
2) In my tests, E10 gives about a 6% reduction in fuel efficiency (ie: less km/L), so if the price is not >6% less, you're paying more $/km.

Global warming - who's interpreting for you?

Amongst the noise and arguments about global warming which is now more generally accepted as being true than not*. One of the things we mere plebs have had to rely on is interpreted data. I found this website www.free-the-memes.net (by searching NASA hottest year on google).
I think it gives a good dose of context on the data for the more scientifically minded.

Now out of this, I decided two things;
1) Global warming is happening with a link to CO2 etc
2) Human activity is contributing to the rise but may not be solely responsible (but we can do something about it to protect health, wealth and happiness).

* - Interestingly baby-boomers/people who were around in the 70's who went through the "next ice age" scare seem most sceptical (understandably)
