Trolley-Buses? (Or Trolley Cars?)
Thats a nice idea, I think... If it could be adapted to cars (Yep, messy and probably fraught with electrocution, tangling and all sorts) it would be great.
Cue using the atmosphere as a means of transmitting power as envisaged a long time ago by crazy scientists.
I'm not completely sold on electric cars. We've already had the Tesla fire debacle, and the "range" debacle. If technology can overcome this, great. Doesn't mean to say that people demanding less for even less won't cause fires and poor-quality batteries to abound.
Nor am I sold on hybrids - particularly because of the amount of resources that are used in shipping components here, there and everywhere across the globe. Yes, fuel economy is a boon - but if it only mitigates the effects (i.e. consumption of fuel, emissions) of production. In the end, is there really any benefit compared to a simplistic, domestic car of the 1950s or 1960s - or even something produced more recently?
The question with these battery-powered cars is what happens to the batteries when they are depleted. Are they really easily recyclable, or is this yet another product we'll poison the soil with? Are the batteries cheaply refurbished or replaced, so you aren't forced into a new car every time one dies?
And with hybrids, do they really net big savings? Delaney's figure of 70mpg is quite impressive for long runs. But as reported, 40-50 around town is expected with the stop-go-stop of city traffic.
A lot of non-hybrids can come close, and depending on the driver, a hybrid may not yield much benefit - a common "soccer mum" driver floor-boarding round town and standing on the brakes would probably not see much benefit if the ICE is running hard to accelerate and charge the battery.

I wonder too where the Hydrogen options have gone? There was quite a bit of hum a few years back, but they seem to have lost press recently. Surely hydrogen would be something "BigOil" could get into, after-all, someone has to make it, right?
Chrysler experimented with their Turbine Car from the 1950's-1980s. While they weren't much in terms of emissions or economy early on, they eventually did develop into great engines. Sadly, thanks to Chrysler's bankruptcy, this concept was scrapped. With today's technology, I bet you could get some nice cars out with this concept: Smooth running (No more 3-cyl rattle boxes!), good economy, low emissions and relatively low noise too. The biggest boon is lack of servicing. Turbines are far more simplistic and seemingly only need minor attention from time to time.
We won't get into nuclear cars, for obvious reasons. Though I think Ford was pushing the idea for a time in the 1950's - complete with an electronic forcefield to ensure any accidents didn't produce a comical-sounding, "meltdown on Main St."
