Cavitation as a Purification Panacea?

The Italian company, Biokavitus has perfected the process of cavitation to the point of now launching several commercial products into the market. And they are open sourcing the core concept to help speed the cleaning of the planet, including nuclear waste, wastewater, oil contamination, but also home cleaning applications. There are health benefits as well - of all living organisms.

Historically, by nature, water is purified by rolling over rocks. Could it be that this introduces natural cavitation effects that are mimicked by this technology that reintroduces this natural phenomenon at the point of use, reinvigorating water?

A couple of weeks ago, I nearly blocked a new contact at Skype who seemed to be doing small talk but nothing more. He asked to become a contact on October 6, the day Andrea Rossi was doing a test of his cold fusion E-Cat module in Bologna. I had asked for contacts from the event who might be able to give us live reports. Since he was from Italy, I presumed he might be one such person. 

He wasn't, but it turns out that he is one of the most amazing contacts I've ever made, and a source of personal satisfaction for all these years of diligent effort in posting free energy news, because he says he got his start from watching a video from a link in our news ten years ago. Now he has a company with 18 personnel, taking a product to market.

He's so grateful for that introduction a decade ago, he has been treating me like a celebrity; yet before he got into this endeavor, he himself was a celebrity, making gobs of money in marketing. He decided to change his focus to making a difference on the planet, and not just making money.

I'm talking about Andrea Rampado of Biokavitus (Bio Cavitation) in Italy. I met him and his associate, Roberto Mezzano, on a Skype video conference a couple of weeks ago; and then in person when I was in Bologna for Andrea Rossi's E-Cat test. Mezzano translated for us.

They have become foremost experts in the subject, methods, and applications of cavitation.

He and his team have so much going that I hardly know where to start this report to you, or what to title this. There are at least 6 separate stories I could write about them, each of them being of a breakthrough nature. And in the coming days, I suspect that these various facets will be more fully articulated, either by myself or by others, as I bring this company to your attention.

How it Works

Usually, when we hear the word "cavitation", we immediately think of the destructive properties of extremely rapidly-moving water. True to one of their favorite sayings, by Galileo, "Behind every problem lies an opportunity," this company has figured out how to provide a wealth of solutions using the beneficial properties of cavitation. And there are some amazing benefits to be had.

In their case, rather than using cavitation from fast volumes of water, they harness what they call the "soft cavitation" that comes when tiny microspheres of water implode. By 'microspheres', I'm referring to bubbles of air in sizes between 50 nm and 50 micrometers. The smaller the bubbles, the stronger their effect. A 50nm bubble, compared to a standard 5mm aerator bubble, results in a 100 thousand increase in its specific surface area relative to its medium.

Water infused with these microbubbles works well in cleaning as well as having anti-bacterial properties. And the amount of energy required to create the bubbles is miniscule compared to their beneficial effects.

In chemical reactions, there are three main factors: a) temperature, b) surface area, and c) agitation. These cavitating microbubbles address all three. Their implosion action results in an increase in temperature and agitation; and the nano-micro size addresses the surface area.

Bubbles smaller than 50 micrometers don't rise through the water like the bubbles we usually think of; but they stay diffused in the water -- Brownian motion -- so their life span is very long.

The bubbles can also have a negative or positive ionic charge to them, adding to their range of properties.

When the water fills with microbubbles of air, the water takes on a white appearance.

Rampado listed eight different methodologies for creating cavitation: mechanical, hydrodynamical, magnetostructive, ultrasonic, laser, ion, microwave, electromagnetic. Having investigated and personally inspected all of these methods, his company has developed a know-how on applying different methods to obtain cavitation in different applications.

More specifically, for wastewater treatment they have chosen the hydrodynamical method, using a simple venturi principle. There are no moving parts, other than what may be involved separately in pressurizing the water to run through their apparatus.

When we met in Bologna on Saturday, they gave my wife and me a shower head that uses regular water pressure to infuse these micro bubbles into the water, resulting in water that feels warmer (due to their high kinetic action), and cleans more deeply, penetrating deep into the pours, dramatically reducing the need of soap. This results in using approximately 30% less water; as well as a reduction in the amount of water that needs to be heated as well as the temperature to which the water needs to be run in the shower. Less water and lower temperatures means cost savings.

It's a great looking appliance, but they aren't even selling it. They give it to their potential customers as a conversation piece and demonstration piece to make their point about the main application they are approaching the customer about.

One incidental thing I should mention that they told me is that the shower head gives off a certain tone, whose pitch is dependent on the speed or pressure of the water going through it.

My Personal Use Experience

This morning, November 5, 2011, I took a shower for the first time using this Biokavitus shower head. Here are some of my observations, as well as those of my wife and son who also have used the new shower head.
  • The aperture of the shower head is very pleasant, giving the impression of a higher-flow of water, given the same volume. It gives a wide dispersal and a powerful feel.
  • We can confirm that we did get away with using at least half the normal volume of soap/shampoo/body wash.
  • My wife says her skin feels smoother.
  • We feel cleaner after the shower, compared to before using this shower head.
  • The sound/tone it makes is quite loud. You can hear it outside the bathroom. This can have an advantage inasmuch as it distinguishes the sound of water running in the sink or tub as opposed to the shower. 
  • As for temperature, I actually turned the heat up higher than before to get the same apparent water temperature; so that portion did not validate.

But the applications are much more than that.

For home applications, this can be used for dishwashers, clothes washing machines as well as general cleaning.

They say it can also be used as drinking water; so conceivably you could treat the mains water coming into the home. For example, the cavitation process removes Chlorine from the water. In the Skype video call, they showed a fish tank in their office that has the bubbles going into it. The fish seemed content. Furthermore, the fish grow faster and are healthier. And no antibiotic is needed for the water because of the anti-bacterial properties of the microbubbles. But what is more astonishing is that the bubbled water enables saltwater fish and freshwater fish to live together in water with 1gr/liter of salt inside.

Rampado said that they have used the water for growing plants as well, and have found that they grow better, larger, faster; and the fruits taste sweeter. Here's a video showing a time-lapsed difference between a control (left) and plants grown with their water (right).

Cavitation can also be used for inexpensive and effective pasteurization without heat.

Rampado showed me a video of them making whipped cream using cavitation. It "stays inflated for weeks," and no preservatives are needed, since the bubbles also prevent bacterial growth.

I asked them about what the water might do for beneficial bacteria that reside on our bodies, including the skin and in our digestion tracts. They said it was fine -- something about the "gentler" version of the cavitation leaving them in tact. But it seemed to me that they had not properly delved into and addressed this question, and that it could be the primary down-side to foods and drinks being treated in this manner, for human consumption. We need our good bacteria. [See follow-up clarification from Rampado below.]

Rampado said the water cavitated with oxygen bubbles has also been shown to be more effective than hypobaric treatment for burn victims.

The purifying and anti-bacterial properties of the water make it a great candidate for wastewater treatment plants. Here is where the costs reductions really can make a big difference -- between 85 and 95% savings, as well as the effectiveness.

Given the three attributes of microbubbles: a) temperature, b) surface area, and c) agitation; you can imagine that it would have a zillion applications in chemistry as well. For example, it can conserve up to 90% energy otherwise required for some chemical reactions.

Biokavitus' nuclear remediation device is shown in the background, right, in this segment from the Leonardo TV series.

But its action is not limited to chemistry. Think nuclear remediation. Rampado says the cavitation effect can treat nuclear waste, reducing the half-life span by 10,000 times, thus accelerating radioactive decay. As a footnote, I should mention that when we met in Bologna, they had Paolo Savaris <> with them, who has developed a method of accelerating doing nuclear decay without also accelerating the nuclear emissions involved during that decay. He has a proof of concept prototype that can be shown.

Rampado once visited a facility that used cavitation to remove CO2 from a power plant emission, splitting the CO2 into carbon and oxygen; and the carbon was fed back into the feedstock to be burned again, greatly improving the efficiency of the plant, while essentially eliminating the CO2 emissions.

He said that cavitation technology can also benefit the production of biodiesel, facilitating nearly every step, resulting in a 80-90% energy savings in the production process. The savings from implementing this in Europe, for example, would be enough to remove 1.6 nuclear power plants from that grid.

Cavitation can also be used for rapidly and efficiently separating oil from water. This is great news for people effected by oil spills. Here's a video demonstrating the separation of oil from water. 

The Russians use cavitation in torpedoes to increase the speed at which they can go through the water -- 800 kph. This is done by a nozzle at the tip of the torpedo that is vibrated to create a cushion of cavitation bubbles that act as a lubricant for the missile as it slides through the water. The U.S. Navy introduced its "ghost ship" that uses a similar method on its catamaran runners, enabling the craft to speed along at 100 mph.

I can't help but wonder how microbubble water might behave in the various electrolysis paradigms people are using in hydroxy research and development. Will it augment the net power output? How much?

What about cold fusion? Will it augment what goes on in the reaction chamber?

At some point, Rampado envisions using the cavitation of a solid/liquid mixture for the purpose of energy generation. He didn't elaborate how he sees that happening.

"Every place there are liquids, we have a solution", Rampado said, adding that they have become the premier experts worldwide in cavitation.

About Biokavitus

Rampado has spent 10 years doing research and development in cavitation, spending 4 million Euros so far, two of that being in the past two years.

Prior to that, he was a very successful marketer, but he left that world to pursue something that he felt would have a more positive effect on mankind. "In marketing, one of the primary tools is to instill in your customer the 'need' for your product. But with this product, that is already well established."

"I want to cavitate the entire world," Rampado said in humor.

In September, they began going to market with their products; but they plan to continue to spend between 20 and 30% of their budget on research and development. This is an order of magnitude more than the average of 3.1% across all industries; and two orders of magnitude more than the 0.3% that the energy spends of their budget on R&D.

Of the 18 personnel on Biokavitus payroll, six of them are working full-time in their present facility, which is 800 square meters.

They showed me their plans for the new building they plan to build and move into by September of next year. It entails two floors of warehouse of 10,000 square meters each floor. The roof will be covered with solar panels to provide 250 kW of electrical power and 600 kW of heat; and they also will be implementing some more exotic energy generation methods as well. A partner company will be occupying the first floor.

Here is a video I shot of my Skype video call on October 12 with Rampado and Mezzano. Forgive the quality, as I was just filming my computer screen.

In this first segment, Rampado and Mezzano describe their technology showing the very basic component; followed by showing me several of their production line products in their warehouse, beginning with a nuclear remediation product; as well as device for the treatment of oil-water emulsions separation device and a biofuel plant capable of producing 4000 tons of biodiesel per year [about ½ ton/hour constantly produced], running off of 10 kW of power, so 20 kWh/tons of biodiesel are immediately produced; and a Russian patented device that separates oil and water . They also show and describe their fish tank with the microbubbles diffusing into it.

In this next segment Rampado and Mezzano show and describe several videos about their technology that are on YouTube, including two instances (1 | 2) where they were featured on the Italian TV show "Leonardo". The first video shows plants' accelerated growth when given the microbubble water. The next video shows oil-water separation. Then is their appearance on "Leonardo", called "Cavitazione", showing a demonstration of separating water and oil from a container that had both in it. Then their "Leonardo" appearance titled "Neutroni da rocce compresse" showing the effect that cavitation had on material strength.

The next, short segment, mentions their interest in Andrea Rosse's E-Cat technology and how they think their technology sheds some light on his process, and could be used to augment his effect of fusing hydrogen and nickel atoms into copper at relatively low temperatures and pressures, producing copious amounts of energy. Don't get your hopes up, the segment basically says, "we should write that up." They explained it earlier in our call, before I had the video camera turned on.

Finally, in the last short segment, Rampado proudly shows off the Bedini electromagnetic device he built, which he says achieved 2.5x overunity. He also expresses his appreciation for our news service and the role it played in fostering his thinking over the past decade.

Added to 'Top Exotic Energy Technologies' Listing

I'm going to be adding Biokavitus to our listing of the "Best Exotic Free Energy Technologies" now emerging into the marketplace. They are not in the energy production sector, but they fit well in the energy conservation genre. And they get the distinction of being listed among the heading, along with the E-Cat, of those who are now in the marketplace.

To know that they were so influenced by our news, and to see how well they are doing now, gives me a great deal of personal satisfaction.

I am hoping that the success of their technology in the quasi open source world will demonstrate to many other inventors, including Andrea Rossi, that open sourcing can be a very productive and financially empowering method of deploying a technology into the marketplace. They don't need it; they say; they are doing fine; but they are glad to play this pioneering role, and have agreed to let us help coordinate that.

I predict that "Biokavitus" will have a prominent name in this chapter of world history, when so much hangs in the balance. "They helped clean up the planet, cleaning up the nuclear waste, cleaning up the water, improving the health of the water and of the people and organisms who drink the water, improving the quality and quantify of agriculture, making a myriad of processes much more efficient, thus saving vast amounts of energy, and eventually even coming up with inexpensive and sustainable energy generation plants. And they did it rapidly and efficiently by deploying the people of the world into a vast array of self-starting companies, creating a productive capacity that helped pull the world economy from the brink of disaster."

Clarification from Andrea Rampado

On November 6, 2011, in response to the question about friendly bacteria, Rampado wrote:
(Translated by Google, with some editing.)

Eliminating the bacteria from a liquid substance does not mean that then the same becomes a bactericidal substance.

The deletion in our case can be made in two distinct phenomena: the first is the power that is using a very driven cavitation that destroys the cell membranes with the shock waves created by the implosion of the bubbles (see, e.g., cavitation aesthetic), the second drive that produces much less micro-nanobubbles positively or negatively charged (may predetermine).

The negative electrostatic charge combined with hyperoxygenation (up to 3 times) creates a toxic and lethal liquid environment for anaerobic bacteria by promoting the proliferation of aerobic bacteria, unlike positive and using CO2 instead of air or pure oxygen creates a liquid environment poisonous and deadly for aerobic organisms favoring the proliferation of anaerobic organisms.

The confusion that has resulted in demand is that your explanations provide confusion between systems that are used for the treatment of industrial liquid and easy to use spray producing an aesthetic water that can be safe to drink, and is certainly not an antibiotic.

To better help you understand, the emulsions used as coolants during the industrial production of mechanical parts in a short time as a result of anaerobic decay and then goes into the liquid must be disposed (only in Europe; is a market of 2.8 billion Euros). With nearly the same energy that is used to recirculate these liquids during operation of machine tools, we are able to enter a special cavitation that can produce different phenomena; hyperventilation and ionization that sterilize and at the same time prevent the proliferation of bacteria anaerobes, and thus the flotation separation of solids and the separation of micropollutants foreign oil. The result is a continuous regeneration of the emulsion and thus no longer discarded.

Energy savings, product and thus a great savings.

And the ability to pasteurize any liquid less than 40 ° C, as another interesting phenomenon is that you can wash at room temperature, dramatically reducing the use of detergents and much more.
