Land Rover has showed off some alternative, environmentally friendly technologies that it expects to incorporate into its vehicles soon. The Land-e concept includes environmental technologies that feature a function that slows the engine to a stop when the vehicle comes to a halt. The vehicle then restarts automatically — quickly and smoothly — when the driver pushes the pedal. At low speeds, the vehicle also uses a 100 percent emission-free electric rear drive.
While off-road, both mechanical and electric power feeds all four wheels. This hybrid system is designed to improve the vehicle's capabilities, as electric engines produce good low end torque and can supplement the low down power of gasoline engines. The vehicle gets greater fuel economy from the automatically disconnecting Powershift gearbox. Land-e also incorporates Land Rover's Terrain Response system, which is designed to optimize on-road fuel economy even further.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Neil Fromer is the executive director of the Resnick Institute, a program for energy and sustainability at the California Institute of Technology, working to develop new ideas and research technologies related to providing a sustainable future. He spoke to us about the severity of the current drought in California and how solar energy can help prevent such situations in the future.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
