As merchants wrapped up a recent day at the St. Helena Farmers Market, curious shoppers stopped for a look at the market’s newest attraction — an all-electric delivery truck freshly imported from Coventry, England.

Unlike hybrid vehicles, this two-seater runs solely on a battery.

“Oh wow!” said Colleen Chappelet as she strolled by the new truck with her 4-year-old son and his young friend. “That’s really great. How much does it cost?”

About $50,000 to $60,000 is the answer, although the vehicle is not commercially available in the U.S.

Ted and Laddie Hall, owners of Long Meadow Ranch in Rutherford, obtained a prototype and plan to use it primarily to deliver wines, oil and other products to restaurants and stores in Napa County. The Halls, who also own Rutherford Gardens, an organic farm off Highway 29, plan to use it to carry goods to sell at the St. Helena Farmers Market as well.

Ted Hall, who recharges the sodium-nickel-chloride battery at the family’s solar-powered ranch, notes the truck emits no emissions  and leaves a “zero carbon footprint.”

The Halls test-drove the truck in England last October. Ted Hall said the truck is quiet, fun and easy to drive.

“There is no compromise,” he added, as he executed a smooth U-turn.

Laddie Hall said the truck only needs to be recharged once or twice a week. Once recharged, the truck can carry a 2-ton payload and drives up to 100 miles at about 50 miles per hour.

A friend of Ted Hall’s, Jamie Borwick, invested $50 million into the development and production of the vehicle by the British firm Modec. The company has produced 80 vehicles so far, according to Modec spokesman William Doelle.

Tesco, a supermarket chain in England, has purchased eight Modec trucks, said Doelle, who did not rule out the possibility that Modec could manufacture all-electric trucks in the United States.

Doelle, who is analyzing the U.S. market for Modec, said the model must be tested by federal regulators before the all-electric truck can be sold in the United States.

Ted Hall, said one run for the new truck was to the famous Sonoma County hideaway Bohemian Grove in July.

“Everyone was amazed,” he said.

The truck is also scheduled to be shown at the International Electric Vehicle Symposium and Exposition — or EVS 23 — Dec. 2-5 in Anaheim.

The first prototypes, designed at London Taxis International, were built four years ago.

Tony Robson, who sells fish at Cap’n Mike’s Holy Smoke near the Long Meadow Ranch’s stall at St. Helena Farmers Market, last week said he first loved the look of the all-electric truck and would love to put a camper on it.

“I’m so totally taken by this vehicle,” he said.
