Pure Energy Systems News 

Everyone that has been following the world of exotic energy should know about the Irish free energy company named Steorn. Over the past several years, they have announced multiple methods of producing overunity gains of energy. For example, they have developed rotary systems that utilize hard and soft magnetic materials, electromagnetic motors that do not produce back EMF, and solid state electrical systems without any moving parts -- all taking advantage of certain aspects of magnetism. 

Now, Steorn has announced an overunity technology that produces massive gains of energy in the form of heat. The name that has been given to the technology is, "Hepha Heat."

In a previous featured article, we mentioned how Steorn was developing an overunity heating technology. For the most part, all we had to go on was a couple videos that Sean McCarthy posted on Facebook. They showed a table top sized system producing a large quantity of steam, with only one kilowatt of input. According to the numbers (temperatures, flow rates, etc) Sean McCarthy provided to PESN, it seems the device may have produced forty times as much output in heat, than was put into the device in the form of electricity. You can check out the videos posted, and the numbers Sean McCarthy provided, here.

For archive purposes, here is what Steorn's website has to say about the technology, as of today. Feel free to click on the links to view this information on their site.

The brand name for Steorn's heating technology is Hepha Heat

Steorn heating systems for water and oil are based on our patent pending low frequency induction heating technology. Our system utilise the power line frequency of 50 / 60Hz to bring the benefits of induction heating without the need for high frequency power supplies.

HephaHeat technology offers the following key advantages:

  • User selected flow rate up to 15 l/min
  • User selected water temperature from 38 — 100°C
  • Delivery volume up to 17:1 — hot water to device size (see graphs)
  • Fast recovery time — start to draw off water within 20% of recharge time
  • Ultra small device size (see table)
  • No limescale build-up due to operational temperature
  • Install at point of use — units can be installed directly where needed
  • HephaHeat units connect directly to a standard mains 13 Amp spur
  • Robust materials ensure Hephaheat technology enjoys long life cycles
  • Ease of manufacture for low cost volume production 

What is HephaHeat Low Frequency Induction Heating?

HephaHeat low frequency induction heating is a patent pending method of using induction systems without the need for additional expensive power supplies.

Our systems are uniquely designed to plug directly into mains supplied AC and by utilising the 50 / 60Hz line frequency we replace the large and expensive power supplies normally required for induction heaters.

Principle of operation

The system works by charging a metallic thermal store to a high temperature (500 to 900°C). By using a material such as steel, which has approximately the same volumetric heat capacity as water, substantially more thermal energy may be retained than in a similar tanked volume of water.

When hot water is required, the cold water input is split into two separate branches. One is allowed to flow into the thermal store with the flow rate controlled by a standard valve. When this branch flows through the thermal store it is instantaneously converted to steam which is then mixed (via a steam injector) into the second branch of cold water.

This mix of steam to cold water allows the output water temperature to be controlled. 

Why HephaHeat?

HephaHeat brings real benefits to water heating systems because of its method of operation, the tables below show performance for delivery volume and a comparison between device size and the high ratio of water produced.


Delivery Volume

The graphs above show the delivery volume for water temperature varying between 38 – 100°C.

HephaHeat units have delivery volumes up to 17 times greater than the device volume for water at 38°C and 4 times greater for a unit delivering water at 100°C.

With one of the highest performance ratios in the industry, the benefits of our technology are clear for product applications including domestic hot water tanks, instant water heaters for under or over sink units and on-demand 100°C taps.

In order to further highlight the benefits of delivered volume of water compared to device volume the following tables display the device volume for typical temperatures and corresponding water volumes produced. HephaHeat units can be sized for any requirement.


Charge and recharge time

While the primary driver behind the charge and recharge time of a HephaHeat unit is determined by unit size and the type of insulation used, the reduced volume and surface area of a HephaHeat unit allows for the use of more advanced insulation materials and techniques than would normally be commercially viable in equivalent tanked systems. Steorn recommends the use of ceramic or vacuum flask insulation to achieve fast charge and recharge times.

In addition to the benefit of a fast charge and recharge time, HephaHeat units do no need to be fully charged in order to deliver water at the required temperature. Typically this can start to be drawn at 20% of the nominal charge time of a given device. 

What is induction heating?

Induction heating relies on the principle of electromagnetic induction. This principle states that when a conductive material is placed in a rapidly changing magnetic field a current will flow in the conductive material.

Typically when using an induction heater the material to be heated is placed in a copper coil which has a rapidly changing magnetic field. As this acts like the primary of a transformer, the material then effectively acts as the short circuit secondary winding of the transformer. The current flow thereby created combined with the resistance properties of the material generate a loss which is expressed as heat.

To date induction coils have been used as a method of precisely and accurately heating conductive materials. Induction heating is found in a variety of applications in the automotive, aerospace and engineering sectors.

The graph below illustrates the typical frequency needed for induction heating applications and the frequency range that HephaHeat operates within.

How Does HephaHeat Work?

In a nutshell, it seems that Steorn has been able to produce a solid state, overunity heating technology. It seems that in addition to the huge OU gains of energy (which are not specifically mentioned on their website), the technology can use the frequency of AC power that comes strait out of a wall socket (50 or 60hz). Most "induction heating" systems have to use much higher frequencies, and require complex power supplies. Steorn's technology is claimed not to need such a power supply, because it can use ordinary grid frequency power. 

For an idea of how this technology may work on a more fundamental level, please take a look at a previous feature article we wrote about Steorn's technology. In the article, we reviewed four bombshell documents that provided clear evidence that supports the validity of their claimed technologies (rotary magnet motor, electromagnetic pulse motor, solid state, etc). Here is the segment of the article that may be relevant to this OU heating technology.

In this paper, the author describes a very simple configuration that involves a coil wrapped around a nickel core (that is both magnetic and conductive) acting as an inductor. The coil and core is placed in a calorimeter composed of a vacuum chamber. Two thermocouples measure the temperature of the coil itself, and the temperature of the air in the room. A metered power supply provides the input power to the coil, and an oscilloscope monitors the current, voltage, and can also calculate total input power by using a math function of the scope.

The purpose of the test is to determine if the coil fed with a quantity of AC power, can produce more heat than the same coil fed with the same quantity of DC power. In the paper, the formula needed to calculate the total AC power is presented. The AC input and DC input is configured to be as identical as possible. Actually, the power input during the AC run was .9 (point nine) watts, and in the DC run it was 1 (one) watt. The fact that the input power during the AC run was slightly less than in the DC run actually biases the test against the AC run. This makes the results of the test even more significant.

In the first test, 1 watt of DC power is fed into the coil wound around the nickel core. The temperature of the coil increases until it reaches an equilibrium point of 36.1 degrees. This is the point at which the power lost by the coil via heat dissipation matches the electrical input power. Even if the input power stayed on for hours longer, the temperature of the coil would not increase above this temperature. 

In the second test, .9 watts is fed into the same coil wound around the same exact nickel core. Obviously, this test took place a period of time after the first one, after the temperature of the coil has dropped back to its original value. The result of AC being fed into the coil is that it rises to an equilibrium temperature of 41.1 degrees. This means that in the AC test, the temperature of the coil reached a temperature five degrees higher than in the DC test. 

The higher equilibrium temperature obtained when the coil was powered with AC, indicates an anomalous gain of energy. The gain of energy is unexplainable, because the input power in both tests were almost identical -- actually slightly less when AC was utilized. As the paper continues, the author indicates that resistive heating cannot be the case for the increased temperature in the AC test run.

The fundamental concept behind Steorn's heating technology seems simple. Apparently, if you run AC power through a coil wrapped around a simple material (that is both ferromagnetic and conductive), a greater amount of heat will be produced than if you ran the same quantity of DC power through the coil. Such a setup can apparently produce overunity gains of energy, in the form of heat. Of course it's probably a bit more complicated than this to produce practical amounts of output, but Steorn seems to have done so. According to the numbers they shared with us, a COP of 40 or more is possible. 

It seems they are pushing this technology towards the water heating market. This is a good target market, because the world uses a vast amount of heat. However, I think it is likely with such a high level of OU, that the technology could be engineered to produce higher temperature steam -- capable of powering electrical generators. Even if the heat to electricity efficiency was only 25% (which is common for electrical generating systems), the system could be closed looped and be self sustaining. Or perhaps the funds from commercializing this technology could be used to further advanced their other technologies, and electricity could be generated more directly. 

Hopefully we will learn more about Steorn's plans for this technology as time goes by. When this technology enters into the market place, it could be a very significant event.

The calculation by MrVibrating for the energy output (and therefore, the COP) of the Orbo heater shown by Shaun McCarthy in the videos only takes into account the heating of water from 20ΊC to 100ΊC, whereas a much greater amount of the energy is consumed in the phase change from liquid to steam at 100ΊC.

The correct calculation is as follows:

Energy needed to heat 1 liter (1 kg) of water from 20ΊC to 100ΊC

1 kg x (100°C - 20°C) x 4.186 kJ/kg °C = 334.88 kJoules

Energy needed to vaporize 1 liter (1 kg) of water

1 kg x 2,261 kJ/kg = 2,261 kJoules

Total energy needed to boil 1 liter (1 kg) of water from 20ΊC

334.88 kJ + 2,261 kJ = 2,595.88 kJoules

Now, the minimum flow rate of water that is vaporized in the Orbo heater is 8 liters per minute, or 480 liters (480 kg) per hour. Therefore, the energy expended per hour is:

480 x 2,595.88 kJ = 1,246,022.4 kJoules

And since 1 kJoule = 0.000277777778 kW-hr, then:

1,246,022.4 kJ x 0.000277777778 kW-hr/kJ = 346.12 kW-hr

In other words, the Orbo heater has a minimum output power of 346.12 kW with an input power of 1 kW, which yields a COP of 346.12.

We will be switching soon to DISQUS, after we sort out some issues in regard to the switchover. The changeover will be occurring in the next few weeks. Initially you will only see new comments (on DISQUS). It will take anything up to 48 hours to get the old comments from Echo reloaded. The downside is that they will be loaded (in Disqus) in date received order, and not the logical order you see here now (in other words some jumbling up will occur).

ADVISORY: With any technology, you take a high risk to invest significant time or money unless (1) independent testing has thoroughly corroborated the technology, (2) the group involved has intellectual rights to the technology, and (3) the group has the ability to make a success of the endeavor.
