Rising pollution, global warming and shrinking fossil fuel reserves have focused world wide attention on how engines generate electrical and mechanical power.
Previous airliners from Boeing, Airbus and other manufacturers have used a combination of electrical and mechanical power drawn from a plane's engines.
The lower density means dramatically less drag force acting on the spinning disk stack so that mechanical power into the motor is substantially reduced.
ENGADGET: HGST develops helium-filled, high-capacity hard drives: no, they won't float away
By combining data from the two steps an equation linking mechanical power (dependent on mass) to electrical power (calculated by multiplying voltage by current) can be derived.
The question is when storing of electricity in batteries or a fuel cell feedstock will become more eonomicial than burning a form of chemical energy to gain mechanical power.
FORBES: Why Solar-Powered Cars Won't Go: They Can't Keep Up With The Combustion Engine
The Department of Defense does not have a submersible that can reach 5, 000 feet with the mechanical arm power to do the types of things that BP and other oil companies buy equipment to do.
Scary yes but inevitable because mechanical technology, muscle power, has barely budged while machine brain power has rocketed ahead, leaving the integration of the two grossly underexploited.
Cold-ironing allows ships at dock to plug into shore-side electricity sources to power electronic and mechanical systems needed for loading and unloading activities.
Power, with perfect scores in the individual mechanical, powertrain, body and interior, and features and accessories categories.
The masters of today's micro-mechanical universe have restored timepieces to the upper echelon of power toys, with attendant bragging rights.
Inside of the Stranger watch is a Ulysse Nardin produced mechanical caliber UN-690 automatic movement with a 48 hour power reserve.
FORBES: Luxury Music Box Wrist Watch Plays "Strangers In The Night"
It has no mechanical moving parts, it uses less than a hundredth the power of a hard disk, and it can be made very small.
In another exciting development, researchers at Georgia Tech have developed a self-charging power cell that's able to directly convert mechanical energy into chemical energy, making it possible to harvest up to five times more energy from footsteps.
Dr. Dennis Leung, assistant professor at Hong Kong University's Department of Mechanical Engineering, says the innovative design will enable people to harness wind power and reducing greenhouse gases at an affordable price.
But for the most part, large power plants cannot shutdown for just one hour as there are thermal and mechanical concerns that put the plant at risk of being damaged for doing so.
Flash memory does not have the mechanical limitations of hard drives, so an SSD has better speed, noise, and power consumption.
FORBES: SSD Flash Storage is Transforming Tomorrow's Business
The so-called Ekso, a mechanical skeleton created by California-based company Ekso Bionics, is designed to give paraplegics the power to walk unaided.
CNN: Bionics: From Hollywood movies to life-changing reality
Fuel pellets can also be placed in the target site using conventional mechanical systems and these should easily be able to cope with the five mini-explosions a second needed to generate power.
So now for something completely different: advanced technology for the last sixty years has meant computing power and its application but the interface with much of the 3 dimensional world is still extremely feeble because mechanical technology has been mostly overlooked since the mindset has been that mechanical has all been done plus it was never and will never be flashy.
