Nissan Leaf battery  (Source: gas2.org)
The home charges the Leaf battery, and eventually, the stored electricity in the battery can be used to charge the home in the event of a blackout

Just last month, Nissan was looking for ways to utilize the battery packs inside of its Leaf EV once the vehicle has reached the end of its lifespan. The automaker found that these batteries will still have 80 percent of their original charge capacity once the Leaf is ready to be laid to rest, and with its plans to release seven EV models (in addition to the Leaf) by 2016, that will be a lot of leftover batteries.

Nissan found that using these batteries as energy storage devices made the most sense. In fact, the company kept four old Leaf batteries in a cellar in a Nissan building, and the batteries were hooked up to 488 solar panels on the roof. This allows the batteries to store the energy that these solar panels create, and the power produced is enough to charge 1,800 Leaf vehicles annually.

Now, Nissan is introducing another similar initiative called "Leaf-to-Home," which will use electricity stored in Leaf batteries to be distributed to residential homes and appliances. The new plan serves as a two-way charging system, meaning that the Leaf can be charged as usual, but the Leaf can eventually return the favor by supplying electricity from its battery when there's a local power outage.

The system is currently being tested in Japan, since March's 9.0-magnitude earthquake caused an energy shortage. The Leaf's 24 kilowatt hour (kWh) battery is capable of powering a Japanese home for two days.

An American home, on the other hand, may not benefit quite as much from such a system due to the fact that the average U.S. home uses 908 kWh electricity per month, which equates to 30 kWh per day. According to recent reports, the Leaf battery would barely charge an American household for a day at full charge. However, it could be useful for a local brown-out. 

Nissan hopes to be able to sell a commercial version of the "Leaf-to-Home" next year in Japan.

I think the leaf and the volt are two of the best looking vehicles irregardless of their electric drivetrain.

Nissan has few good looking cars left. The GTR looks great, but the Sentra and Versa rank up their with the ugly Korean bunch.

Toyota has 0 good looking cars, including Lexus. But they're reliable, functional, and the quality of materials is good for the money, so people buy them and enjoy them from the steering wheel perspective.

Scion is a love-hate thing with just about anybody you ask.

Honda has some good looking cars but they don't get the fuel economy other manufactures get and they cost too much for what you get.

Ford has good looking cars lately mostly due to their European influences.

GM is in a similar situation as Ford, carrying over their European and Australian styling to the American market.

Crystler...I'll leave it alone.

BMW, Audi and Mercedes are all so obsessed with eachother that they practically make the same vehicles. I'm tired of everybody ripping off the Audi LED accent lighting too. It didn't look good in the first place, so why are you copying it? I've also seen a unbelievable number of Audi's with the LED lighting failing, ie, left side works, right side doesn't...

The Audi is the meanest looking car on the street. That LED look is enough to make me buy one. And their sport editions - sweet jesus can those go.
If only I could afford it...
