They only need to weigh less than batteries. Over a third of a Tesla Roadster's weight is batteries.
Interesting articles. I think that “Booze in a Bag” has a real future.
Some good back-of-the-cereal-box-reading here: http://flywheel.esmartbiz.com/facts.htm
I remember those! I had the Black Jack in blue chrome.
I had the Black Jack!
And how will the extra energy needed to spin the flywheel and carry its weight be offset by transferring its reduced spin to power the wheels? Sounds like perpetual motion to me.
The E-2A Navy airplane carried a drum data storage drive. It was big and heavy and turned at a high speed. When they test flew it the airplane wouldn’t turn because of the drum’s gyroscopic rigidity in space.
It’s not a ‘new’ technology. It has been used in the past. Switzerland used it to power trolleys and it has even been used in a Formula one racing engine. The process works and has worked. It seems just right for hybrid cars.........
They would still need to mount it like a gyro.
On rotating axis.
Those things will act like C4 in an accident.
They’re running them in F-1 and those boys wreck pretty hard.
Think of an electric DC motor, you have the rotor and the stator around it. Make the rotor flat and wide, and make the stator all-enclosing, not even a driveshaft protrudes. Then suck all the air out of the stator.
Apply electricity to spin that sucker up. Then remember that a DC motor is a DC generator, just depends on whether you’re adding electricity to create torque in the rotor, or using the rotor’s existing torque to create electricity.
People used to worry about the idea of driving a car that carries ten gallons of a highly flammable liquid.
The torque issues are real, no matter how the flywheel is oriented.
But equal counter-rotating wheels will address the issue fully, given a sturdy frame to connect them.
I wonder if a normally sealed unit - as sealed as most ordinary sealed units are in cars today, filled with some very slippery but dense liquid..
Accompanied by the repeal of the laws of physics that govern gyroscopes.
Oh, wait... it sounds sorta like that already (not as much cam lope). They did do a good job of making it read the engine speed through the cigarette lighter socket, though.
Just the newest version of this concept, I guess.
No wonder I am NOT an engineer in the field of fluid dynamics. Thanks for the reality check.
Since F-1 cars turn both left and right, I assume they have dealt with your concern.
