@wakeangel2001 They would not only be charging stations, but would be grid feed stations (in the case where electric cars had solar cells on the roof), so that there is a benefit to the grid which gets more power to meet peak demands, as well as a benefit to the car owner/user who gets to recharge their car. Assuming sunlight, and assuming tough solar cells on car roofs (we recently had a hail storm here that has left a lot of cars on the road looking like golf balls).

(CNN) — A highway-worthy airplane moves one step closer to production with a recent weight exemption approved by the Federal Aviation Administration.

The Transition Roadable Aircraft, developed by Massachusetts-based engineering firm (…)

Transition is designed for trips of up to about 450 miles and can travel about 100 miles per hour in the air and “highway speeds” on the ground (…)

the Transition will cost $194,000. The first delivery will occur in about 18 months (…)

Supercar!

Why feed the energy from the car battery to your grid? Why not just directly power your house with it? Only surplus goes into the grid.

amazing video! this explains a lot of my questions about electric cars! Thanks

I see, compared to the potential revenue the grid could gain the investment of setting up charging stations around the block (which could be as simple as a weather protected outlet sticking out of the ground) is a minor cost.

@wakeangel2001
When apartment buildings and housing projects figure out that charging stations plus electric vehicles produce revenue, you will see them become available. There are a number of initiatives in several states to set up charging stations.

this is all fascinating, but I have one question. I live in an apartment in the projects, I and hundreds of neighbors don’t have a garage, we all simply park on the street. I’m certain that this situation is true for millions of city dwellers throughout the world. If we were to get plug in hybrids, where exactly would we plug them in? I think we’re going to need to commit to at least one more change in infrastructure so we can all have outlets available.

@tantpwei Their power plants are up to 40% less efficient than our latest plants. Batteries are terribly inefficient (takes 1.6 watts to charge 1 watt). They are also far dirtier. Coal fired power plants produce all kinds of nasty stuff besides co2. Believe me, right now the Chinese are better off with diesel fuel cars.

@christo930 Electric cars are more than 80% efficient in converting its energy while gasoline cars’ efficiency less than 15%. So even if the electric power plant is 40% less efficient it still makes plenty of sense to switch to electric car.
