Eco Factor: Speed reading device runs on solar power.
In some places you get a ticket for speeding above the limit, others just warn you and leave you to drive at a decent speed, but the City of Calgary is trying a new approach – scolding you like a parent. The city has installed new speed reading devices that are equipped with radar that checks the speed of a passing vehicle and if it’s above the rated limit it displays a scolding message.
The city has purchased 16 of the new devices that only flash the limit, each of which is priced at $5940. The devices carry a solar panel that generates all the power the system requires, which lowers their operating costs and means less ground wiring.
