Solar Taxi
A Swiss inventor has completed the first trip around the world in a solar-powered car.
Louis Palmer travelled 32,000 miles through 38 different countries since setting off in July last year
The car arrived in the Polish city of Poznan in time for the UN conference on climate change The car arrived in the Polish city of Poznan in time for the UN conference on climate change.
Mr Palmer said he wanted to raise awareness of alternative energy sources as delegates from some 190 nations work towards a new treaty to limit pollution.
He said: "I hope really that the car industry they hear these signs and they really change and make electric cars in the future,"
Mr Palmer's prototype was not cheap to manufacture - it cost him about the same as two Ferrari sports cars.
But he reckons his invention would sell at around 8,700 if the big car makers manufactured it.

New Ultra Efficient Motor Just Sips Electricity
Nova Torque Inc. in California have announced on their website that they have now developed a brushless dc. electric motor that runs on 10% to 30% less electricity than conventional electric motors.
Since billions of electric motors consume more than half of all electricity in the world, any improvements in motor electricity consumption could represent a massive difference in world electricity consumption.
DC sources of electricity such as solar power systems do not now require an expensive dc./ac. inverter to operate these cheaper, lighter high torque dc. motors thus potentially lowering the cost of many power systems.
Applications include motor drives for equipment where high efficiency, high speed, continuous torque and cool operation are important.
For example, Pumps, dishwashers, geothermal, pool, well, irrigation, HVAC & refrigeration: air conditioning, freezers, ventilation fans, cars, scooters, bikes, golf carts, forklifts, marine, motion control robotics, factory automation, conveyors and so on.
Smaller lighter conical magnets are used in these compact newly patented motors that require 40% less steel and 50% less copper to manufacture reported Anita Hamilton in Time magazine.
Sizes of the new Nova Torque motors range fro 500 watts to 150 KW or Fractional Horse Power up to 200 Horse Power.
Specialty: aeronautics, down-hole motorsa patented technology which provides unprecedented levels of energy efficiency. We are proud to offer an important breakthrough in the efficiency sector of the Clean Tech market. Read more
Nova Torque motors provide more output power in smaller sizes than any other electric motor on the market today. Our unique DC brushless motor design provides numerous advantages over conventional motors, and is ideally suited to applications where high efficiency, high speed, greater continuous torque or cooler operation is critical.
This ground-breaking motor technology has countless possible applications, including:

World Economic Forum
December 4, 2008 -- Cologny/Geneva, Switzerland -- NovaTorque, Inc. has created a patented electric motor technology which represents an important breakthrough for the motor industry and an exciting development in the "clean tech" field. NovaTorque's innovative motor structure provides:
Much greater efficiency than existing motor technologies
Higher torque in smaller sizes
Better thermal performance
Competitive manufacturing costs.
Importance of Motor Efficiency
Motors consume about half of all electricity produced. Because there are billions of electric motors in use, even small efficiency improvements could make a huge difference in total electricity consumption and save $100 billion annually in energy costs. NovaTorque motors are an astounding 10-30% more efficient than conventional motors. Their unique design is also more compact, runs cooler, and produces more output power than any other type of small motor.
NovaTorque History
NovaTorque's technology grew from the confluence of several factors: improved magnetic modeling, improved materials and techniques with which to make motors, and the need for much more efficient motors. NovaTorque has spent four years developing this new technology, which can scale from fractional HP (500W) to greater than 200 HP (150 kW). The motors are DC brushless motors (also categorized as Electronically Commutated Permanent Magnet motors) and run with standard motor drive electronics.
