Apps can include background services, but by design they can't start the services on install, they are only allowed to start them when the application is run for the first time, or when the device is rebooted. However they can hook system events on install so the app can be launched when the phone receives an SMS for example.
The lead-acid battery GM EV-1 was supposed to get 100 miles on a 10 kWHr charge (yeah, yeah, YMMV).
The EV-1 lead-acid batteries were 16.5kWh and 55-75 miles range according to Wikipedia (0.3-0.22kWh/mile). The 27kWh NiMH battery pack had a similar kWh to miles ratio (75-150 miles range so 0.36-0.18kWh/mile). The Volt does about the same with 10kWh (it doesn't use the full battery capacity to increase longevity) for a 35-50 mile range (.28-.2 kWh/mile).
Under normal, battery-charged conditions and under 70 MPH, the gasoline engine does not run at all.
This is not correct. The gas engine doesn't turn on at all when the car is in electric mode, even when driving over 70mph. When the car is in charge-sustaining mode, that is the battery is depleted, the gas engine is directly connected to the wheels under certain conditions from 30mph.
GM says:"The engine WILL NOT turn on while the car is in electric driving mode (which for your trip two days ago approached 50 miles) – simply put, it is a full-performance battery electric vehicle.
Once the battery is depleted, the Volt’s gas-powered engine engages to create the power needed to extend the range of the vehicle several hundred additional miles. In extended range mode the Volt is powered by either a 1-motor series or 2-motor combined mode. The vehicle will select the most efficient mode for the driving condition: 1-motor series – for operations almost exclusively below 30 mph; 2-motor combined almost exclusively above 70 mph. At speeds in between 30-70 mph, the Volt will select the most optimally efficient drive mode amongst the two."
At the time of the vote in parliament to approve the war the war British public opinion based on a simple yes-no poll was in favour of the war, and remained so for quite a while afterwards.
