I finally got my interview with Rick uploaded, after adding a bunch of relevant images to go along with the audio file.
It's a great perspective from someone who has become a significant advocate, as to why he got involved.

This is in follow-up to the story we posted a few days ago:

: Subject: Exotic tiny water to power technology developing
: This looks like an interesting development in breaking water apart and there by harvesting unexpected energy. The possibilities (not well understood) could open big doors in new energy development and merit mention on your blog.
: Thomas Dodgson
Here's an excerpt:
: Engineers have built a powerful microscopic engine that relies on the combustion of hydrogen and oxygen. One problem: nobody knows how it works.
: Engines have played a crucial part in the industrialization of the world. It’s hard to think of an innovation that has had more impact.
: The trend today is toward smaller, more efficient engines. There are jet engines the size of coffee cups powering autonomous aircraft and powerful electric motors that make children’s helicopters more useful than anything that was possible just 10 years ago.
: But there are good reasons to think that combustion engines are unlikely to get much smaller any time soon. Combustion engines become hugely inefficient as they get smaller because heat leaks away faster. That’s the inevitable result of the way that volume and surface area change relative to each other as things get smaller. (The same effect is the reason mice have a hard time staying warm while elephants have a hard time cooling down.)
: So most microactuators rely on other effects to produce force. There are two main categories: thermal forces, which tend to be slow, and electrostatic forces, which tend to be weak. What’s needed is something that’s stronger and quicker.
: Today, Vitaly Svetovoy at the University of Twente say they’ve discovered an entirely new mechanism for producing forces on the microscale that are both powerful and fast. And while they do not yet fully understand this mechanism, they believe it is based on the dissociation of water into hydrogen and oxygen gas and its recombination back into water.
: These guys have even built a microengine demonstrating the phenomenon. “This actuator is the first step to truly microscopic combustion engines,” they say.
: The new micro-combustion engine is simple in principle. It consists of a tiny chamber filled with water and containing a pair of electrodes attached to a circuit. Passing a current through the circuit causes the water to dissociate into oxygen and hydrogen, which then form nanobubbles.
: Although these bubbles are too small to see, the volume of gas dramatically increases the pressure in the chamber, causing a membrane at one end to deform. This is what generates force.
: When the current stops, the pressure drops rapidly. So quickly, in fact, that the researchers aren’t entirely sure why. It’s certainly too fast for conventional processes such as the gas diffusing out of the chamber or dissolving back into the liquid.
: But Svetovoy and [___??] think they know what’s going on. Their idea is that when the current is switched off, the hydrogen and oxygen in the nanobubbles spontaneously combust, forming back into water. It is this combustion and the removal of the gas that causes the pressure to drop so rapidly.
: Whatever the mechanism, they apply an alternating voltage/current at 50 KHz to create their engine. This produces a constant source of bubbles for combustion and causes a back-and-forth vibration of the membrane, which can be used to do work. Voila! A microscopic combustion engine.

Last Wednesday, we reported:
I spoke with Ben just now. He said that they ran into mechanical problems and were not able to give a successful demonstration. They scrambled and tried to get a new generator to run, but it was larger than the one they had been using, so it only ran for a few seconds on the water mist (flow rate wasn't adequate) -- not long enough to be convincing.
Around 17 people showed up from around the U.S., including Alaska, and signed NDAs. He felt bad that they had gone through the time and expense of traveling to see their demo.
Ben expects to get his system running by next weekend, at which point he will shoot a private video to show those who have signed NDAs.
When I asked him if he wishes he had two generators operation for redundancy for the demo, he replied, "We are operating on a limited budget, and have to make do with what we have."
