400-600% Overunity Cooling Machine

A university project created a cooling system that creates about 600% more work than it takes to run the system using memory metal.

In this brief article, you’ll learn how something can easily produce way more work than it takes to run it and there are no violations of physics.

Electric heating element heaters are energy hogs for the heat they produce but regardless, they are 100% efficient already. And there is nothing magical or special about a 100% efficient heating system.

Why? Because nichrome or other heating element wire is thought to dissipate or waste all the electrical current that runs through it. That is not even close to being the reality, but that is what conventional science believes so we’ll just entertain that for the purposes of this article and to keep it simple. Normally, heat is considered waste in non-heat systems but if you power a heating element and it “wastes” all the electricity, then it is 100% efficient since the desired work is the heat.

Efficiency is a funny subject because as absolute as it sounds, it is really an objective measurement because efficiency changes depending on your perspective of what kind of work you want.

An incandescent bulb is considered 10% efficient since the desired work is light while 90% of the energy is “wasted” in heat. However, if we want to use those bulbs as heaters, then magically, they would be considered 90% efficient, with 10% wasted as light. But if you want some heat AND light, then the bulb is also magically considered 100% efficient since 100% of what you are using to power the bulb is creating both power and light.

Heat pumps create hundreds of percent more heat/cooling than the electricity required to run them – geothermal, refrigerators, air conditioners, air source heat pump dryers and water heaters, etc. yet, they are less efficient than heating element heaters.

Efficiency is a ratio of TOTAL input to TOTAL output. The heating element produces as much heat as the wattage is provided. It is 100% efficient.

But there is another measurement, COP or Coefficient of Performance, which is the ratio of ONLY WHAT WE PROVIDE on the input compared to the TOTAL output. With a heating element, we provide all the input so total output divided by our input will equal 1.0 or COP of 1.0.

With heat pumps, the story is very different. If it takes 200 watts of electricity to run a compressor to circulate a refrigerant through compressions and expansions cycles (that creates high and low potentials in the system), heat moves for free towards a colder area so the total amount of heat moved in a heat pump can easily be 300, 400, 500, or 600 watts worth of work in an electrical equivalent – for only paying 200 at the wall.

If you put in 200 but you get 600 watts of heat movement, the total desired work is 600 watts worth divided by only your input (not counting free environmental contribution) of 200 watts = 3.0 or COP of 3.0. That is a 300% NET GAIN in total energy (work) produced compared to what you have to pay for. But if you look at all input including environmental input, it will be under 100% since  there are losses. That is how you can have a system that produced hundreds of percent more work compared to what you pay for although it will still be 100% efficient of less.

The cooling system methodology created by a team led by Professors Stefan Seelecke and Andreas Schütze at Saarland University is technically not new in concept, but it is the best example of taking advantage of an interesting memory metal called Nitinol and it’s known effects of soaking up heat while it gets bent and releasing the heat when it straightens out.

The cooling system is made of a cylindrical chamber with a rotor that has nitinol metal strings running along the length. There is a cam system that flexes the wire as it rotates for 1/2 the revolution. During this 1/2, the wires soak up heat in that compartment, which cools the compartment down. When the wires goes into the other side of the chamber, they are allowed to straighten up and they release a lot of heat, which heats up that compartment.

There is air moving through the devices to move both the hot and cold air. The claims from the university is that it is about twice as efficient as a heat pump. As you know from the examples above that a heat pump could have a COP of 2.0 or 3.0 easily. That means that this new Nitinol cooling device would have a COP of 4.0-6.0 or 400-600% more work done than the motor takes to rotate the cylinder!

Although the recent buzz has been talking about this latest development as if it is new, but the university has been at this project for several years.

It also has this graphic that illustrates a bit of how it works –  this is not shown in any of the recent media releases.

Evaporative Refrigerator

Evaporative Refrigerator

A group of students from the University of Calgary have developed a simple evaporative refrigerator. It was inspired by the way that animals and insects keep themselves cool.

Warm air from the surroundings is funneled into a pipe network to evaporate water moisture, which carries heat away from the air. Once the air is cooled, it moves into the chamber where the food is kept. The only power requirement to bring the temperature down to 4C is to power a small fan to move this cool air, which can be done with a very small battery setup powered by a small solar panel.  The refrigerator still works with no electricity but works best with the fan.

Silent Refrigeration

A refrigerator uses a traditional heat pump. A compressor is powered usually by electricity and that circulates a “refrigerant” like freon or some synthetic version through some tubes that go through heat exchangers – the bottom line is that is pulls the heat out of the fridge to make it cold.

An AC is just another variation of this as is all other heat pump technologies such as heat pump hot water heaters. Some give you cold while expelling the heat and some give you heat while expelling the cold.

Heat pumps are a really great technology and are very reliable and have made our lives much easier. There are a few drawbacks such as the noise and occasional maintenance due to moving parts.

Phononic is a company, which has eliminated these problems by building a completely silent and solid state refrigerator using hundred year old Peltier junctions…they’re semiconductors basically that get hot on one side and cold on the other.

Peltier’s definitely work but their drawback is that they are very inefficient…it takes a lot of watt hours to produce any substantial heating or cooling, but Phononic has scaled them up and have made them more efficient than ever. Normally, they’re under 10% efficient, but now they’re over 30%!

Phononic heat pump

Even at 30%, they can’t compete with heat pumps in terms of Coefficient of Performance (COP), but being that they are much smaller than normal compressor heat pumps and they’re silent, they do have their place.

While this advancement in Peltier technology isn’t going to get anyone off the grid, it is a very welcome improvement as a three times increase in efficiency in anything doesn’t happen every day.

To put that into perspective – the automobile engine was commonly under 20% efficient and the newest cars on the road today are lucky to achieve 30% efficiency – and that is over many, many decades of automotive advancements.
