     With the Tesla Roadster and other plugin (插入式) electric vehicles hitting the road, demand is

growing for accessible refueling points to recharge them. Carbon Day Automotive, a Chicagobased

company, has now demonstrated a solarpowered recharging point, known as the Solar PlugIn Station,

which lets motorists easily charge their cars using electricity that has been produced without any

environmental damage.  

     The Solar PlugIn Station has gone on show in Chicago as part of the city's bid to host the 2016

Olympic Games. According to Carbon Day Automotive, the Solar PlugIn Station on show in Chicago is

part of the vital infrastructure(基础设施) required for electric vehicles in Chicago and was the focus of

a recent visit by the International Olympic Committee.

     These solarpowered electricity points will be used daily to fuel the city's electric vehicles with power

from the sun. By producing the electricity from pollutionfree solar cell, the CO2 emissions are reduced to

zero. "Solar energy and electric vehicles are a partnership that is one more step to reducing our

dependence on foreign oil," says Richard Lowenthal, CEO of Coulomb Technologies. Coulomb

Technologies recently developed the components (部件) required for individual recharging stations,

marketed as ChargePoint Networked Charging Stations. Carbon Day Automotive is the Midwest

distributor for the ChargePoint stations. The Solar PlugIn Station consists of giant solar panels (电池板)

that shade the tiny ChargePoint Networked Charging Station.The solar panel is connected to an

underground battery pack, ready for everyday refueling.

     "Without these stations it would be like driving around in a traditional car without the availability of

gas stations," says Scott Emalfarb, CEO at Carbon Day. "The day of true plugin electric vehicles will be

here sooner than most people realize and the world needs to be ready to accommodate them."
