Summary:
The cheetah is not only the world's fastest land animal, it is also one of the most energy efficient, expending only what it needs to survive. It's that efficiency that engineers at MIT are working to emulate in a robotic cheetah, already clocked as the second fast robot ever developed.

The Physics Behind Oracle's America's Cup Victory

The Physics Behind Oracle's America's Cup Victory

FORA.tv (Oct. 4, 2013) — The Physics Behind Oracle's America's Cup Victory California Academy of Sciences - African Hall Why go fast? Compared to moving slowly, the advantages seem obvious: find food first, forage more widely, and escape more rapidly! But, in the water, being speedier incurs huge energetic costs, with moving a little bit faster skyrocketing the amount of fuel you need. This trade-off between speed and energy propels the evolutionary race for fish, robots, or sailboats: you have to find ways to go faster with ever-greater efficiency. Over generations, the evolutionary race can produce biological and engineering surprises: distantly related fish and boat hulls that have similar streamlined shapes, materials and construction techniques that manage to both stiffen and lighten bodies and hulls, specialization of propulsive systems, and constraints on making turns and tight maneuvers. While the evolutionary processes employed by nature and engineers are similar, there are important differences in how fish or boats are built. For both kinds of designers, the laws of evolution and physics interact to create and constrain the drive for speed. Dr Long will discuss how robotics research lab studies fast fish! A book signing will follow the talk for Dr. Long's latest book titled Darwin's Devices: What Evolving Robots Can Teach Us About the History of Life and the Future of Technology.

Thailand Climate Protection Through Energy Efficiency

Thailand Climate Protection Through Energy Efficiency

Deutsche Welle (Mar. 13, 2012) — Thailand needs ever more energy for its industry. It already imports up to 10 percent of its electricity. The growth of industry is bringing a sharp rise in greenhouse gas emissions. Now a German-Thai project funded by the International Climate Protection Initiative is working for a more efficient use of energy, thereby contributing to climate protection.The Thai government has a long-term goal of "Low-Carbon Industry". It is collaborating with Germany in the umbrella organization "Energy Efficiency for Small and Medium Enterprises" on several pilot energy-efficiency projects in small and mid-sized companies. The Environment Ministry holds consultations regularly. The aim is to cooperate with German experts and develop an "Energy Use and Climate Protection Plan" for Thailand's economy.

2014 Tesla Model S P85+ Takes on the Ike Gauntlet Review (Part 3)

2014 Tesla Model S P85+ Takes on the Ike Gauntlet Review (Part 3)

TFL Car (Nov. 14, 2013) — ( http://www.TFLcar.com ) The Tesla Model S P85 is a revolutionary car that says goodbye to the internal combustion engine and hello to the electric motor. But how will this all electric car do when the road gets steep and the altitude gets to two miles above sea level. From Dillion, Colorado to the Eisenhower Tunnel US I-70 climbs 8 miles to a maximum elevation of 11,158 feet or 3,401 meters. That's enough elevation and grade to test a small economy car like the 2014 Ford Fiesta and the Chevy Sonic Turbo, but how will the 2014 Tesla Model S P85+ perform on the same stretch of American Highway? In Part 3 of another accurate, informative and fun TFLcar mashup review Nathan, Emme, Andre and Roman take on the Ike Gauntlet in the new 2014 Ford Fiesta and Chevy Sonic Turbo and the most powerful electric production car...the 2014 Tesla Model S P85+ to see how these small cars handle the steep grade and lack of air density in the Mountains of Colorado.
