David Taylor of Dallas-based Electric Mobile Cars, LLC brought one of his models to show off at the downtown convention. They take Renault bodies and outfit them with a batttery.

"We just decided we don't want to be the guy standing on the porch saying, 'It's coming! It's coming!'" said the EMC rep.
