Battery Powered Flight

I’ve been excited about electric cars for a couple of years now. No, not hybrids that require a fuel tank an an internal combustion engine but cars that have an electric motor and a battery pack that is plugged in to recharge. I believe electric cars and nuclear power plants are the key to our energy independence and reigning in our output of greenhouse gases. Now it looks like my dream of electric powered transportation can go even farther.

Electraflyer Corporation has strapped an electric motor and a lithium polymer battery pack on an old Monnet motorglider built from a kit, and the aircraft just this week earned its experimental airworthiness certificate. The company is also flying a battery powered ultralight trike which has about 50 hours on it.

I know this is a long ways from commercial flight but so was the Wright Flyer. Besides, with Avgas running at over $6.00 per gallon these days this could be the one innovation that keeps recreational flying attainable by ordinary pilots.

No Gifts for Marines

I’m really interested to see where this goes.  Marine Sgt. Rick Sanchez is a career soldier who received an expensive gift has been relieved of duty and is under an investigation that could lead to a court martial. A Marine Corps spokesperson has stated that, “as of now it doesn’t look like he’s done anything illegal but we are still investigating.” So I have to wonder is this really a story?

To Infinity and Beyond

I have no problem with people who claim to be agnostic. Lord knows I’ve been there and still find myself wondering at times. Still I consider myself a devout Christian who can recite the Apostle’s Creed with conviction.

Atheists, however, are another matter. I don’t dislike them I just can not fathom how anyone can say, “There is no God,” with any certainty. I don’t understand them and I can’t help but view their certainty of there being no god as a bit of arrogance.

I know it may seem hypocritical of me to view an atheists certainty of there being no god and not some believers certainty that there is but I don’t see it that way. To me I can understand someone taking even the flimsiest bit of evidence of a god and having it become a certainty but just because to another there is a lack of evidence can not lead to a certainty that there is no God.

Look at it this way, we really have no universal definition of what a supreme being might be. On top of that we really have no consensus that a god has to be a supreme being or that just any supreme being is a god. Since we really don’t know what a god or a supreme being might be how can we say it doesn’t exist?

To look at it another way we live in a complex universe. The more we find out about it the more we find that we don’t know. Some look at the universe as being boundless, without limits or as constantly expanding. We understand the basic laws of physics and how they work but when we go beyond the basics we continue to find things to be just a little more complex than what we fully understand. We get a grasp on that complexity and that opens up even more complexity.

The complexities are proving to be more and more enormous the more we look. So are we so arrogant then as to think that we are looking at something that the human mind is fully capable of completely understanding? I’m not saying that it is useless and that we should stop looking and theorizing but what I am saying is that I don’t expect us to ever be able to comprehend the laws of physics completely, at least not in our current form.

So where am I going with this? If we can’t fully understand our universe, and by that we I’m also including the physicist who is so intelligent he can comprehend 26 different dimensions in a theory that has merit throughout the scientific community, if we can’t come to an agreement on what a supreme being might be or what a god is, how can we be so arrogant as to make the bold statement that there is no Creator God? How can anyone possibly state with any confidence at all that it all just happened?

Now, with that said I can fully understand someone telling me they can’t believe in a Sky Wizard or some invisible Magic Man. I find those terms offensive to me but I can understand someone not being able to believe in the God of the Bible or the Koran or any of the pagan gods out there. I just can’t understand how anyone can say with any certainty that there is no God, period.

Mt. Soledad

I’m on the west coast this week and next. I drove down to San Diego last night from Los Angeles. Things didn’t go all that well in Los Angeles. I managed to break a robot pretty bad. I’m taking today off before starting an install at a customers site in the morning. I’ll probably be back in LA for a few days next week and then back down here in San Diego again.

This is an extended trip.

DSCN2283

This morning I had breakfast, wrote up a short report of what happened yesterday and sent pictures of the destruction to a couple of people. I can’t share those here. However, I did drive up to Mt. Soledad after finishing the report and took some pictures I could share.

This is a beautiful mountain top. I just wish haze hadn’t been so bad.

Presidential Primary Blues

I’m depressed. The only candidate for the Democratic nomination for President of the United States who brings the experience needed to the table to actually perform the job from day one has just dropped out of the race. I can’t in good conscious vote for Senators Clinton, Obama or Edwards. I just don’t see them as people capable of being the president I want leading my country. I’m not sure there is a Republican candidate for the nomination that I feel any different about.

This may be the first presidential election I opt out of.

Presidential Picks

As of right now I only see three candidates that I believe are capable of holding the office of President of the United States. This has nothing to do with ideology, I’m not ready to pick on that yet, this is based purely on credentials and integrity. Two are Republicans and one is a Democrat.

 I like Bill Richardson. I disagree with him on many of the issues but I believe his life experiences have left him most qualified of any of the candidates to be president. I’m really surprised he is running behind Edwards, Obama and Clinton in the polls. None of these Democratic frontrunners have anywhere near the experience in running a government as he does. None of them have the diplomatic experience he does and none of them have the policy making experience he does. Bill Richardson is a remarkable man. He also strikes me as a man of integrity.

Of the Republicans you have Mitt Romney and Mike Huckabee who both have demonstrated skills in running government and both man appear to be men of integrity. Out of the Republicans, who more has experience running government than these two men? Gulliani may come close but running city government, even a city government as large as New York City does not fully prepare one for running a country.

I like Huckabee a little better than Romney, though and if I was voting in the Republican Primary today I think I’d choose Huckabee. He’s a FairTax supporter, you know. I think I like Richardson the best of the three, though. I worry a little about a Dominionist bent with Huckabee.

You’ve got to serve somebody.

This past week I’ve been talking to some friends about God. One of my friends wanted to know how I rationalized other gods to my own. It’s fairly easy. I’m a monotheist. There is only one God so the other gods he’s speaking of must just be different names for my God. He wasn’t very satisfied with my answer. Other religions worship their God differently than I worship my God. They have different creation stories and such. How could they be my God by a different name.

I understand his confusion. He’s an atheist and doesn’t believe in any gods. I can appreciate that he doesn’t believe in a supernatural being and this leads to his confusion in my answer. He does believe that there are things more important than just living his life to the fullest so there is something bigger than him, something he must serve. While I believe in God as a supernatural being I also believe that your god is who you serve. Micah 6:8 tells us exactly what my God requires from me to serve Him. I must act justly, love mercy and walk humbly with my God. From what I’ve gathered from my Hindu friends, that’s what Brahman requires from them in order to reach Nirvana. Same God, different names, different rituals, different stories.

Still, I believe the important part isn’t the name of the god or the ritual or the stories. The important part is how you serve God. I believe we serve God by serving His creation and it only really counts is that our motivation for doing so is our love of God. Call God what you will, just love Him and serve Him and you are on the right path. To me, that’s all what believing in Christ is all about and everybody has to serve somebody.

Flying

This is possibly the most incredible thing I’ve ever seen. I know y’all have seen these people jumping out of airplanes in these wingsuits and the camera shows them flying around with no close background to use to really judge what they are doing or how fast they are traveling. The guys are base jumping off some mountain in Norway with these suits and you do have very close background to judge how fast they are going and what stunts they are actually performing.

<sigh> I was born about thirty years too late.

Forensic Engineering

Okay, I just told you about the problems I’m having with a job in NYC. This problem is kicking my tail something awful and it shouldn’t be that hard. Of course you can always make it hard on yourself when you assume things and then don’t revise your assumptions as new facts come in.

This application uses a 15kw regenerative vacuum pump to create the motive force to move a lightweight granular solid about thirty yards. A 15kw motor equates to about 20hp. My first impression was the the company we used to build this system for us had skimped on materials and sized the overload and starter as small as they thought they could get by with. Maybe that assumption was wrong.

In the US we use horsepower (hp) to measure power. In Europe, where this pump was made, they use kilowatts (kw) to measure power. The overload and starter are perfectly sized for a 15hp motor. In this brand of regenerative vacuum pump a 15hp (11kw) pump is a stock, off the shelf item. Their 20hp (15kw) pump is a long lead time item. Are things starting to add up?

I’m thinking that the original designer of my system called up the distributor for this pump to order the pump. The distributor asked what size and my designer said “15″ meaning 15hp. The distributor then sold him a a 15kw pump thinking that was what he was talking about. Everything got put together and it ran…. for a time. I believe that a month ago this time ran out.

I’m ordering a positive displacement pump to replace this regen pump first thing Monday morning. It will be the proper horsepower.

It really isn’t that difficult

Most of what I do these days isn’t that difficult. I’m not working with cutting edge components or elaborate electrical circuits or even complex control schemes. It’s all pretty basic.

 Why then am I having so much trouble getting a vacuum pump to run at a customer’s site?

On October 23rd I arrived at my customer’s location to find that a 20hp vacuum pump used in a pnuematic conveying system was down with two legs of its windings shorted out. This is a regenerative pump with the motor made into the pump housing. I wasn’t going to pick up a motor at the local electrical supply house to replace it. A replacement pump has a five week lead time so the only alternative I had was to have the motor and pump rebuilt.

This meant my customer would be down one week. He really wasn’t happy about this. I can’t say I blame him.

I hired a local pump and compressor specialist company to take care of removing the pump and rebuilding it for me and reinstalling the pump. I’m fairly satisfied with the work they did but I’m a little disappointed I couldn’t lean a little heavier on them for support with the electrical. Along with a bad pump I had a bad 60A rotating disconnect that was shooting sparks out whenever the motor started and an overload protector that was tripping out that hadn’t been tripping out before.

The overload was replaced with the same size overload that came with the system but I was a little concerned about the vendor we bought it from sizing it too small from the beginning. It had been holding, though. The contractor I was using did not want to change out the disconnect. I hired the same electrical contractor that installed the power wiring for the system when we first installed it to replace the rotating disconnect.

The reason I’m hiring this stuff to be done is that I am in Atlanta and the job is in NYC. I made the original visit and diagnosis and I was there this past Friday to determine that the disconnect had to be changed. Rather than fly back to install the disconnect I figured I could hire it done locally. I hired a licensed, union electrician thinking that if there was another problem he could take care of it for me. The other problem arose but it wasn’t taken care of.

The overload I was concerned about was a problem. Even though it was the same size, even the same manufacturer and model, it wouldn’t hold with the newly rewound motor. Evidently we were right on the hairy edge of tripping with the inrush current from the old windings and the slight difference in the new windings was enough to cause the motor to trip.

I asked the electrician if he could replace it for me. He said he would have to talk to his boss. The next I heard was from my customer saying the electrician had left mumbling something about being expected to be an engineer.

The new overload is in my bag. My flight is at 8:10AM in the morning.

I’m really not a hard guy to please and I need to build contacts in cities across the country so I can have names of people who can do what I do to get my customer back up and running. Living in Atlanta I can be anywhere in the US in 24 hours but sometimes even that is too long of a time and occasionally weather conditions delay flying.

If you are a controls technician and you live in the NYC, Cambridge, New Haven, CT or Gainesville, FL area I’d like to get contact information from you. I can’t promise you any work but I’d like to know someone in these areas to call if I have problems. I basically need people who can diagnose and repair electrical problems in control systems who live near medical research facilities.

 Like I said I can’t promise anything, I just need contact information just in case. Click on the contact button above and drop me a line if you fit what I need.

For those of you wondering…

I’m still kicking around and traveling way too much. For several reasons I just haven’t had much to say. I keep having ideas for an essay but I can’t seem to bring those ideas into anything I would find interesting to read so I keep those ideas to myself hoping that I can find a way outside of an abstract to express them.

I find most of those ideas coming about while I’m driving. Maybe a voice recorder could help me there.

L.A.

Los Angeles was interesting.

This was my first time there. The job involved three pick and place robots. I managed to crash all three. Two were violent enough to tear things up. There are some talks going on now between my boss and the owner of the company that built the robots for us over the crashes.

It wasn’t all work, though. I visited Santa Monica Pier and Venice Beach. Not much to mention in Santa Monica but there was plenty of weirdness in Venice. Street performers, artists, ladies on skates and muscle men were all around.
The strangest sight of all, though, occurred right outside of UCLA Medical Center at a bus stop on the corner of Tiverton Avenue and Le Conte Boulevard. About 7:30a.m. Pacific Time I was driving into UCLA Medical Center to begin the day’s work. I glanced over and saw a dirty, grungy bearded, older man drop his trousers and defecate on the sidewalk. There were people on the sidewalk jumping back in horror as this occurred. As I drove on into work I couldn’t help but think, “Who’s going to have to clean that up?”

Mistaken Identity…. again

Beep

Mr. Burton, this is Dr. K’s office. Please call our office in regards to a foot x-ray we received for you from Dekalb Medical Center.

Beep

Larry, this is Dr. K. I need to talk to fairly urgently. Would you please call my office when you get this message

Beep

These are the messages I had on my answering machine Yesterday morning. Dr. K had just performed knee surgery on me this past Tuesday and I thought I was recovering well. What did a foot xray have to do with anything. I hadn’t had a foot x-ray in about three years.

I gave Dr. K’s office a call but he hadn’t arrived at the office yet. It was still before 9:00am. I went about my business and pretty much forgot about the call. Around 9:15am Dr. K returned my call.

“Larry, are you okay?”

“Yes,” I replied. “Things are going great with my knee. All I have is a little muscle soreness now but the joint itself feels great.”

“Good, good, but listen, I received an x-ray of a leg where the foot had been amputated with all sorts of pins in the leg and it had your name on it with me as the doctor. I was worried you had been in an accident on the way home from your surgery. Everything is alright, right?”

Dr. K was fairly upset with the mix up but I was a little amused. It seems I’m the victim of mistaken identity on a fairly regular basis.

Empty House

I had my knee surgery this past Tuesday and so far everything is going well with it. The doctor found a torn meniscus rather than a cyst causing the problems. The muscles around the knee are sore but the joint its self already feels better.

My wife left for a week to spend some time with her mother vacationing in Florida. I was suppose to go but….

I start my new job in the morning so I’m off to Albion, NY for a couple of days. With my wife and son gone to Florida that meant boarding the dogs for a few days. I had to drop them off yesterday (Saturday) and I’ll pick them back up Wednesday morning when I get back.

I’ve not known what to do with myself the since I dropped them off. This house seems awfully empty.

Ch-ch-ch-changes

In my last post I was sitting in an airport bemoaning my lack of time due to my long commute. I just took a step to correct that. I have accepted a job with Matrix Scientific and will start work with them the first of August. The company is located in Albion, NY and I’ll be working from home. Travel appears to be more frequent than with Factory Automation Systems but the duration of time away from home will be much, much less.

Between now and my start date I’m having a cyst removed from my knee. This has been causing me trouble and giving me a lot of pain for over a year now. I finally went to an orthopedic surgeon over this and as soon as we found out what the problem was I scheduled the surgery.

By fall I should be able to tackle hiking the Georgia portion of the Appalachian trail. This has been something I’ve wanted to do for some time now but first the job and then my knee got in the way of accomplishing the trek. I will be taking on sections of this portion of the trail on weekends.
