Tennessee residents are able to see and touch environmentally-friendly cars, trucks and buses that don’t use even a drop of gasoline during the next two weeks.

The Alternative Fuel Vehicle Roadshow in Tennessee is underway and is co-sponsored by Efacec.

The event stopped in Kingsport and Knoxville, will be in Chattanooga today; and in Memphis March 25 and Nashville March 26. The showcase is open to the public, though registration is required.

Efacec demonstrates its DC fast charger at the showcase. It looks like a fuel pump, but instead of filling cars up with expensive gasoline, it quickly powers them with domestically-produced clean electricity. Instead of plugging in an electric car overnight, Efacec’s fast charger recharges a battery to 80 percent in just 28 to 30 minutes. The company said several are already installed in a number of cities.

“Efacec is helping to power the cars of the future,” said Mario Santos, Efacec’s Director of Business Development for Transportation, Electric Mobility. “Electric cars need charging stations just as gasoline-fueled cars needed gas stations to catch on. The more fast chargers there are, the more likely people in Tennessee and all over the country will be to buy and drive energy-efficient vehicles.”

The event features several clean-energy vehicles — even a school bus — that run on fuels that are not gasoline. In addition to electricity, these fuels include compressed natural gas, propane and biofuel.

Efacec previously sponsored roadshows in Georgia and Florida.

East Tennessee Clean Fuels Coalition director Jonathan Overly directs the program in Kingsport, Knoxville and Chattanooga, while Atha Comiskey with Middle Tennessee Clean Fuels and Paul Rice with West Tennessee will host in Nashville and Memphis.

The Tour is produced by AdVentures, a private company, producing nonprofit and educational events with a social purpose.
