Tesla Hackers Show an Energy Revolution Closer Than Once Thought

Day trader Jason Hughes works on running electoral wiring to junction boxes used to convert captured solar energy to store in Tesla Motors Inc. batteries in Hickory, North Carolina, U.S., on Tuesday, Feb. 10, 2015. Hughes spent the better part of last year hacking a 1,400-pound battery recovered from a wrecked Tesla Model S and reworking it into a stacked array that can store energy from his solar-power system.
