Battery powered cars spark debate and trial in Boston
Boston Edison installs fast charging gear for electric cars amid state zero emission rules and industry pushback. Ford notes cost and battery limits while Solectria plans mass production. Mechanics adapt as inspectors query nonexistant exhaust and alarm at new tech challenges.
Solectria Aims for Mass Production of Zero Emission Cars
Solectria Inc aims to mass produce electric vehicles by 1998 joining the push for zero emission cars in Massachusetts New York and California. since 1989 the Wilmington company has converted dozens of Geo Metros and small trucks to battery power while improving lead acid and nickel zinc chemistries to extend range to 100 200 miles.

Electric cars powered by massive batteries and high costs
The article notes electric cars run on large batteries weighing about 500 pounds, half the vehicle weight, requiring six to ten hours to recharge. They offer about 40 miles per charge now, with projections to 100 to 200 miles, and price ranges from 20 000 to 50 000 dollars. Industries see cattle and oil impact and debate persists among Detroit automakers and utilities over government mandates and micro-power potential.
