According to testimony from a police corruption trial currently roiling the city of Philadelphia, officers from an undercover drug squad took the latter route back in November 2007. After arresting their suspect, Michael Cascioli, in the hallway outside his 18th floor apartment, the officers took Cascioli back inside. Although they lacked a search warrant, the cops searched Cascioli's rooms anyway. According to a federal indictment (PDF), the officers 'repeatedly assaulted and threatened [Cascioli] during the search to obtain information about the location of money, drugs, and drug suppliers.' That included, according to Cascioli, lifting him over the edge of his balcony to try to frighten out of him the password to his Palm Pilot. That sounds like a good time for a duress password.
But utilities say that solar-generated electricity flowing out of houses and into a power grid designed to carry it in the other direction has caused unanticipated voltage fluctuations that can overload circuits, burn lines and lead to brownouts or blackouts. "At every different moment, we have to make sure that the amount of power we generate is equal to the amount of energy being used, and if we don't keep that balance things go unstable," says Colton Ching, vice president for energy delivery at Hawaiian Electric, pointing to the illuminated graphs and diagrams tracking energy production from wind and solar farms, as well as coal-fueled generators in the utility's main control room. But the rooftop systems are "essentially invisible to us," says Ching, "because they sit behind a customer's meter and we don't have a means to directly measure them." The utility wants to cut roughly in half the amount it pays customers for solar electricity they send back to the grid. "Hawaii's case is not isolated," says Massoud Amin. "When we push year-on-year 30 to 40 percent growth in this market, with the number of installations doubling, quickly — every two years or so — there's going to be problems."
