Test: The Perpetual motion Quiz

The earliest references to perpetual motion machines date back to 1150, by an _____n mathematician-astronomer, Bhāskara II.

The most conventional type of perpetual motion machine is a mechanical system which sustains motion while inevitably losing energy to friction and air resistance.

The entire _____ relies on a system where thermal output exceeds the thermal input.

The seemingly mysterious ability of _____s to influence motion at a distance without any apparent energy source has long appealed to inventors.

In a _____, forces tending to turn the ratchet one way are able to do so while forces in the other direction aren't.

This has been debunked by _____ as constituting a perpetual-motion device.

Serious work in _____ often involves thought experiments that test the boundaries of understanding of physical laws.

_____ created a series of claimed perpetual motion machines in the 18th Century.

If someone points out to you that your pet theory of the _____ is in disagreement with Maxwell's equations — then so much the worse for Maxwell's equations.

Devising these machines is a favourite pastime of many eccentrics, who often come up with elaborate machines in the style of _____ or Heath Robinson.

Scientists are currently spending many research hours in attempt of getting more power out of _____ than what it takes to run the power plant.

This would actually be a low-efficiency solar generator, far less efficient than conventional _____.

This need not violate the law of conservation of energy, since the thermal energy may be equivalent to the work done; however it does violate the more subtle _____ .

Such a device or system would be in violation of the law of _____, which states that energy can never be created or destroyed, and is therefore impossible.

_____ in 1235 described, in a thirty-three page manuscript, a perpetual motion machine of the second kind.

_____'s self-flowing flask appears to fill itself through siphon action.

A rejection under _____ U.S.C. _____ for lack of utility should not be based on grounds that the invention is frivolous, fraudulent or against public policy.

Perpetual motion violates either the _____, the second law of thermodynamics, or both.
