I am just an ignorant old country boy, but to me it seems the scientific hucksters are managing to get government money to work on another version of a perpetual motion machine. Is it possible to put X energy in and get X+ energy out? :wacko:

"Perpetual motion describes hypothetical machines that operate or produce useful work indefinitely and, more generally, hypothetical machines that produce more work or energy than they consume, whether they might operate indefinitely or not.
There is undisputed scientific consensus that perpetual motion in a closed system would violate the first law of thermodynamics and/or the second law of thermodynamics. Machines which extract energy from seemingly perpetual sources—such as ocean currents—are indeed capable of moving "perpetually" (for as long as that energy source itself endures), but they are not considered to be perpetual motion machines because they are consuming energy from an external source and are not closed systems. Similarly, machines which comply with both laws of thermodynamics but access energy from obscure sources are sometimes referred to as perpetual motion machines, although they also do not meet the standard criteria for the name.
Despite the fact that successful closed system perpetual motion devices are physically impossible in terms of our current understanding of the laws of physics, the pursuit of perpetual motion remains popular.

Basic principles
Main article: Thermodynamics
There is an undisputed scientific consensus that perpetual motion in a closed system violates either the first law of thermodynamics, the second law of thermodynamics, or both. The first law of thermodynamics is essentially a statement of conservation of energy. The second law can be phrased in several different ways, the most intuitive of which is that heat flows spontaneously from hotter to colder places; the most well known statement is that entropy tends to increase, or at the least stay the same; another statement is that no heat engine (an engine which produces work while moving heat between two separate places) can be more efficient than a Carnot heat engine.
In other words:

1. In any closed system, you cann
ot
create new energy (first law of thermodynamics)

2. You always lose a little energy (second law of thermodynamics)

3. Therefore a machine cann
ot
make more energy than it uses or even enough to keep itself operating.

Machines which comply with both laws of thermodynamics by accessing energy from unconventional sources are sometimes referred to as perpetual motion machines, although they do not meet the standard criteria for the name. By way of example, clocks and other low-power machines, such as Cox's timepiece, have been designed to run on the differences in barometric pressure or temperature between night and day. These machines have a source of energy, albeit one which is not readily apparent so that they only seem to violate the laws of thermodynamics.
Machines which extract energy from seemingly perpetual sources - such as ocean currents - are indeed capable of moving "perpetually" until that energy source runs down. But they are not considered to be perpetual motion machines because they are consuming energy from an external source and are not closed systems."

The Scientific community and their priesthood spend a great deal of their time educating us to the fact that they will be the saviors of the world. The God of creation says it ain't gonna happen! :lol:

God bless,

Ge 3:19 In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.

Man's dream is not to put out any sweat, labor,, yet eat as the king does, no sweat.

I can remember our science teacher, back in the 1950s, telling us of m an's attempts at creating perpetual energy. I can only remember one of them, though.
