USPTO office action on Ballistic Breakers

My continuation in part patent application on Ballistic Breakers will be allowed. Claims 1-19 are allowed as submitted; there is a  technical issue with claim 20 that can easily be overcome. This is the second time in a month that I have had very good news on the patent front. My US patent application on elpipes will also be granted soon, based on USPTO actions.

This is extremely good news, and shows my strategy to have been reasonable. If I had a lot of money, I would have been much more in stealth mode. I did it this way because I had to talk about my ideas in order to find investors, and that meant filing patent applications so I could speak about my inventions. I have now found an investor who is interested in backing both Electric Pipeline Corporation and Ballistic Breaker Corporation, and he never would have found me if not for my strategy.

PCT Patent application link & status report on Ballistic Breaker™

The Ballistic Breaker is called a "commutating circuit breaker" in both my US and PCT (Patent Cooperation Treaty) patent applications. I decided to post my (now published) PCT patent application here to make it easy to access. The PCT patent application also adds a little bit more subject matter and a few more claims over my earlier US patent application.

The patent application applies to numerous implementations of the basic concept: 
  • linear motion actuation or rotary actuation; 
  • multiple stages can be used to divide the voltage so as to allow high voltage ballistic breakers with many stages;
  • gradation of the resistivity of trailing edges of the electrodes to further inhibit arcing upon electrode separation;
  • motion can be actuated by springs, gas pressure, stepper motors, or stretched wire or fibers (for example);
  • Use of correlated magnetic domains to accurately define the on state of the circuit breaker (subsidiary to US patent 8,098,122 to Correlated Magnetics);
  • Use of piezoelectric actuators as super-fast releases.

For a quick introduction to Ballistic Breakers, check these links: 



I recently filed a continuation-in-part US utility patent application that is based on both my February 6, 2012 US patent application and my PCT patent application, but adding in a bit more IP and two more claims.

My comment on the Energy Innovation by Statoil blogsite today

Ian said:

New Scientist and Statoil asked specifically what will have the largest near future impact, not what could. Not sure the winner and runner-ups reflect this important distinction



I commented:

On the positive side of this, I hope that 50 years from now we can look back and realize just what saved us. My leading candidates:

1) LENR (by that I specifically mean the nuclear fusion reactions of nickel with light (normal) hydrogen; if that works out it will surely be the most important thing.

2) If not that, then I'm betting on a supergrid to save us.

When the shit hits the fan, there will be a panicky rush for solutions. Unfortunately only proven technologies will qualify for panic funding. My goal is to have my invention elpipes ready when that moment arrives; see www.elpipe.com

I filed my "Continuation-in-Part" US Patent Application today

Each major redrafting of this patent has been a big improvement. First, my US patent application was filed on February 6, 2012, based on three prior provisionals. Then I greatly improved on that, and also added some new subject matter and claims in my PCT patent application, filed October 1, 2012. This "Continuation-in-Part" US patent application filed today added two new claims from the PCT (it is now 37 claims), and I am very happy with it. I believe it is valid, but I do expect challenges will be made by the examiner that probe at the relationship between Ballistic Breakers and two particular prior technologies:

  1. Automatic tap changers for AC transformers
  2. Rheostats
I expect the examiner to find a few patents I missed, because the old patents are hard to search.

My "Startup Pivot" from elpipes to Ballistic Breaker


My inter-related inventions on high capacity HVDC transmission are key enablers for a supergrid. And a supergrid is the key to developing an energy economy based on aggregating numerous non-dispatchable generation resources (wind, solar, tidal). Both inventions (elpipes and Ballistic Breakers) are simple and seem obvious once you hear of them, yet both are revolutionary innovations. These innovations could make it practical to share hundreds of gigawatts (GW) of power across Europe, Asia, or North America, for example (this is the order of magnitude of new transmission needed to create a renewable energy economy), and that vision motivated me to pursue elpipes starting in 2008, after Obama's election victory.

Elpipes combine a pair of pipelines similar to gas pipelines with high capacity power lines that can move inside the pipes with features of a train. An elpipe is a very heavy high voltage DC (HVDC) power line that can carry more power than any overhead power line, with lower transmission loss. To do this, elpipes use more than 10 times as much conductor as the largest overhead lines; an elpipe is made up of heavy rigid conductors that are effectively the rail cars of an elpipe train. The elpipe train can run on conventional rails, or it can be designed to run inside a pipeline. An elpipe train could be thousands of kilometers long, yet the entire elpipe train would be fabricated at one location, then rolled into the conduit like a very long, low speed electric train. This method of installation splits the project into three parts: building the conduit, which is either a rail line or a gas pipeline; fabrication of the “elpipe cars” in a factory process; and assembly of the “elpipe cars” into a train at one single point of assembly (in a clean room environment, with sophisticated quality control inspection equipment deployed). This is very good for both cost of the elpipe and for reliability of the splices. Read more about elpipes at www.elpipe.com; I pursued elpipes for two years, and everyone with money said it is "too big, too long term" for venture funding. I came close to a deal with ABB to pursue elpipes in a strategic partnership in September 2010, but that was blocked by one ABB senior executive, Willi Paul. Shortly after this, I invented the Ballistic Breaker; this invention woke me up at 3:30 AM October 2, 2010. I have continued to work on my big dream of elpipes, though my focus is now on Ballistic Breakers.

The other missing piece of the puzzle for enabling a supergrid besides a high capacity underground conductor (elpipes) is a very high capacity low cost circuit breaker for HVDC power. The power electronic HVDC circuit breakers being offered by ABB are too expensive and too lossy to work at the scale needed in development of a supergrid. Ballistic Breakers are my second surprisingly simple innovation: these devices enable DC circuit breakers to be developed at any voltage and power level (they get bigger as power level goes up). Although I invented Ballistic Breakers for HVDC, they have an immediate market in medium voltage DC; in fact, Ballistic Breakers are key enablers for DC grids at all size scales, from vehicles to data centers to microgrids to the supergrid. So I have made the classic "startup pivot" and am now pursuing MVDC Ballistic Breakers with initial market: big motors.

I am also quite interested in applying Ballistic Breakers to DC data centers, which are growing rapidly. In this application, the low switching transients of Ballistic Breakers is especially important. For most data center installations, the desirable voltage level is only 380 volts. This low voltage implies a lot of amps (2632 amps/MW), which also is an opening for elpipes, since some data centers consume as much as 300 MW. In this application, a very high ampacity low voltage elpipe could be part of the data center power delivery system.

Tesla was on track to invent the Ballistic Breaker

Nikola Tesla is one of my heroes, though I hope to have more business sense than him. When I was writing my US patent application on Ballistic Breakers (*here is an excerpt) it worried me greatly that there might be some very old prior art (which is impossible to find in an online patent search). On a whim, realizing that Tesla was brilliant, I decided to browse through Tesla's 111 US patents on the odd chance that one of his patents might be relevant. In fact, Tesla's US Patent 382,845 is one of the closest prior art patents, and creates a link between my work and one of the great pioneers in electricity.

The story behind US patent 382,845 is truly interesting, and I only know part of it. Tesla came over to the US at Thomas Edison's invitation, and agreed to Edison's proposal that he work on a bounty basis (I got this from a Tesla biography). Edison wanted Tesla to figure out how to stop the commutators of DC motors and/or generators from sparking, and offered him (verbally) a $50,000 bounty if he could succeed. The resultant US patent 382,845 is the only one of Tesla's patents that deals with DC power at all. Edison never paid the bounty which led to Tesla breaking off the relationship and becoming Edison's sworn rival. This patent reveals a remarkably simple way to suppress the commutator arcing, which I also use in the Ballistic Breaker: just behind the conductive brush that makes contact with the rotating commutator is an insulating material (a mica board) that is in contact with the conductive brush, and is squeezed against the commutator as well. This leaves no room for the spark in effect, and arcing is suppressed; a remarkably simple and effective solution. Tesla's patent is remarkable in another way: it is the only patent I have ever seen that is half assigned (to Charles F. Peck); I assume that there is an interesting story behind that as well.

I believe that if egoic considerations had not gotten in the way, Edison and Tesla might have continued to work together. Had that happened, I believe Tesla would have invented the commutating circuit breaker 120 years ago. This was one of the next problems that needed to be solved to make wide area DC power transmission & distribution practical. Instead, Tesla never looked back at DC power and his inventions ushered in the age of AC. DC power equipment quickly became a backwater technology, and there was little innovation until the modern age of HVDC and DC microgrids. By that time vacuum tubes and transistors had been invented, and recent work on DC circuit breakers has mostly used these innovations. My invention Ballistic Breakers goes back to basics and picks up a thread of innovation that was abandoned by Tesla long ago.
