What comes first? The sexy all-electric car, or the smart carbon-free grid to power it? Whichever way round it is, its going to take machines like the one above to turn enough heads quick enough to make a new generation of transport a reality. (And the current crop don't quite do the job.)
The changes that are going to be required over the next couple of decades to move to a sustainable relationship with CO2 are only going to be possible with a radical transformation and adaptation of our existing behaviours as we reconsider everything about the how and why of what we produce and consume.
The tension between the need to rapidly get our act together and the reality that trying to cut our way to success is probably not going to change things quick enough means that a big part of the solution is going to have to come from introducing enticing alternatives to our existing way of doing things.
The soon to arrive new generation Toyota Prius and the young upstart Honda Insight hybrids are certainly a first step on the journey, however the sooner we can go all-electric the better, with low-carbon juice of course as standard.
So if Tesla is to be believed the car's nearly there and we're even starting to get the rather lovely looking charging stations popping up around the West End of London, but the way things are going the 'Political will' seems to be somewhat lacking if we're going to get enough carbon-free juice to power these babies in a short-enough time-period.
It would be naive to think that enough people are spontaneously going to be prepared to individually reduce their use of energy and consumption habits quick enough to make enough of a difference. And to be honest to be really believe that the way to achieve this is by heaping further guilt on to and already economically battered and bruised population?
So clearly we're also going to need some of what Terry Macalister outlined in the Guardian today;
None of this is trivial, but the reality is that this will only work if it all works. The whole journey encompassing, idea, product, delivery and experience.
