JAKE LINGEMAN for AutoWeek: Aim for those bumps; save the planet. Audi is working on a new suspension system called eROT (electromechanical rotary damper) that turns the kinetic energy of damper travel into usable, fuel-saving power.
“Every pothole, every bump, every curve induces kinetic energy in the car. Today’s dampers absorb this energy, which is lost in the form of heat,” said Dr. Stefan Knirsch, board member for technical development at Audi AG. “With the new electromechanical damper system in the 48-volt electrical system, we put this energy to use. It also presents us and our customers with entirely new possibilities for adjusting the suspension.”
The electromechanical dampers are arranged horizontally and feed electricity from the motion -- 100 to 150 watts on an average road during testing in Germany -- to a lithium-ion battery. A DC converter connects the 48-volt electrical subsystem to the 12-volt primary. Cont'd...
Professional weather sensors form the heart of large solar plants supporting their operation and performance. Lufft was the first manufacturer to combine several sensors in one housing, bringing the largest multiparameter weather sensor family with 19 members into being.
Many of them are well-suited for solar site assessment and continuous monitoring. The most commonly used one is the WS600 delivering data on temperature, air pressure, wind, relative humidity and precipitation. Through its open protocol, it can easily be attached to radiation sensors e.g. from Kipp&Zonen. Other models have an integrated Silicon, Second Class or Secondary Standard radiation sensor.
