Car Runs On Air? - Don't Fall For This!

The other day a guy at work sent me this link to a story about a car that runs on air.  Compressed air motors are nothing new.  Our boys had little cars that shot across the room after they pumped up the air tank.  Before there were tiny gasoline engines that powered model airplanes, they used compressed air.  I have read numerous articles about compressed air motors for years, some of the inventors making amazing claims about how far and fast they can travel on a tank of compressed air.

What got me about this video were not the claims by the inventor but the ridiculous conclusions by the reporter.  Anyone who has filled an air mattress on a camping trip or blown up one of those huge inflatable swimming pools knows first hand that compressed air is NOT FREE!  It comes with a price, and sometimes a huge price depending upon the volume of air or the pressure of the air that is required.  Can you imagine blowing up the tire of your car with your lungs?  Compressed air is not free!  Not only is it NOT free, but it is also not an efficient way to power a motor, like the motor of a car.

The main inefficiency comes when the air is compressed.  Wherever this takes place, there is a huge energy loss due to the heating of the air during the action of compressing the air.  It is the same when you pump up your bike tire with a hand pump.  The base of the bike pump can get so hot you can't touch it without burning yourself.  All that energy that is used to heat the air is lost into the atmosphere.  It takes a lot of electricity to compress air.  A lot more energy that you get out of it in the motor of a car that runs on air.

It is a scam!  Don't believe it, especially at the end of the video when the reporter starts talking about perpetual motion and using compressed air to generate more compressed air.  It is ridiculous!

Incentive Is A Key To Performance

I was at work the other day when a FedEx deliveryman sauntered in with a package. He casually had the receptionist sign for the package and then he sauntered out. I followed him out to his truck, and began a conversation that went like this:

"Why don't you run like the UPS delivery guys?" I asked.

His response was clear and to the point, "Because they get paid by how many pieces they deliver and FedEx pays me by the hour."

There is no incentive for the FedEx delivery guy to hurry since he doesn't get paid more when he does.

The simple moral to the story is: Incentive is a key to performance.

UPS v.s. USPS v.s. FedEx - Don't Ask Obama

The other day Barack Obama was quoted as saying,

"UPS and FedEx are doing just fine. It's the Post Office that's always having problems."

What I believe Obama was trying to say was that a government run health-care system would not hurt private medical insurance. The message that the poor man sent was just the opposite. What a stupid example! When I heard what he said all I could see was standing in long lines at the Post Office and the DMV.

Nobody wants a health-care system that works like the US Post Office.

A second point that Obama failed to make was that if the US Post Office is having such a hard time competing with private companies, why in all the world would he want to create a health-care system that will have the same disadvantage?

President Obama is not doing well right now as he struggles to promote a government run health-care system. He does not appear to know what he is talking about. First he claims that a government run agency has trouble competing with private interprise and then he claims that the governemt run agency will not need to be subsudized by the government. His teleprompters must have malfunctioned in the worst way!

This example shows that Obama simply does not understand how capitalism works. It also shows that he does not understand that all of governemt by definition is subsidized by the taxpayer.

Big Government Will Always Be Late

My wife and I arrived at the train station a bit early so that we wouldn't be rushed. We had spent a wonderful weekend in San Luis Obispo but were anxious to enjoy the senic train ride home down the coast of California. After unloading our luggage from the shuttle and carrying it inside the depot, I immediately noticed a lack of other passengers.

"Where is everyone?" I asked myself.

When I looked out the door to the train tracks and did not see the train, I knew something was wrong. Going against my male instinct never to ask for help, I approached the desk.

"Where is the train?" I inquired of the man behind the counter. He was wearing a wonderful uniform with a large belt full of different colored tickets and an official Railroad Punch. I could tell he was really busy, because it took him about a minute before he stopped reading the newspaper and looked up at me.

"What's your question?" he asked, keeping his finger on the part of the news story where he had stopped to answer my question..

Now you must understand that I am no stranger to working with government employees. I have worked in the aerospace industry for years and I could tell you dozens of stories about the gross inefficiency of big government. Afterall who else but big government could produce a $1000 toilet seat?

And don't forget the Department of Motor Vehicles. Ever since I learned to drive I hated to go to the DMV. You have to wait in one long line after another just to submit the form to take the written test, then another line to get the test graded, and another line to have your picture taken, and another line to pay your fees, and another line to take the driving test, only to have to wait 90 days to get the actual license in the mail.

Or what about the Federal Passport process? I remember standing at the counter in the Federal Building in Santa Monica, CA, while the government employee spent 5 minutes filling his stapler with fresh staples and mending the hanger for his calendar so that he could mark off the days until he got his next fat paycheck. I didn't dare say anything for fear that my urgent passport application might mysteriously finds its way into the trash bin at his feet.

No, this was not my first encounter with a finely tuned organization, owned and operated by big government.

"Where is the train?" I repeated to the man behind the train counter.

As I expected, he was slow to respond, but finally he said, "It's about six hours late. It should be here about 6 o'clock this evening." He continued, "You see this train originated in Seattle, Washington, and a lot can go wrong between here and Seattle."

"There goes our senic ride up the coast," I mumbled to my wife when I returned to the hard wooden bench where she was sitting. "It will be nearly dark by then," I explained to her.

My wife and I kept busy during the long wait, taking pictures, reading magazines and visiting with fellow passengers. Many had arrived to find out that the train was even later than they had been told. I met a wonderful family from North Platte, Nebraska, who were enjoying a month long family vacation traveling by train across the country. The father explained how relaxing it was to sit back and look out the windows without a care in the world.

"There is only one problem, that you MUST overcome," he warned me. "You must forget about following any kind of schedule or time table. The trains are NEVER on time."

"You don't need to tell me about that," I responded. "We've been sitting here for over five hours waiting for our train."

When I looked at my inexpensive Timex watch, it was nearly 6 o'clock. A quick glance out the window to the empty railroad track prepared me what I knew was inevitable. There must be another delay. I approached the counter to find out.

"It's a long way from Seattle," he told me again. "They had some problems at the last station and were delayed on a siding up the track. They should be here shortly."

About an hour later, we heard a garbled announcement over the ancient public address system. The train was approaching. We drug our luggage out to the platform and I pulled out my camera to record the arrival.

As we loaded our luggage onto the train. I thought to myself....

How will it be when the US health care system is run with the same efficiency and competence as Amtrak? I have been to the UK and I know first hand that going to a doctor in England is no different that visiting a veterinarian in the US, except that they mop the floors more often in the US.

And what will it be like to have the US government produce our automobiles at the new Government Motors? It could very well turn into the situation like they had in Germany before WWII when Hitler ordered the design and manufacture of the Volkswagen ("The People's Car"). If it hadn't been for funding from the Third Reich and mandatory payroll deductions, nobody would ever have owned one.

One thing I know for sure, whatever happens in the US with healthcare, banking, and the automobile industry, our experience with Amtrak is typical of what we can expect.

Pay your taxes and enjoy the ride....Too bad it is six hours late!
