Clearly, that represents a lot less waste in a much more manageable form than if the whole primary apparatus has to be scrapped periodically. However, WRT the tritium issue: You wrote "> As Jerry Isler pointed out...don't confuse commercial nuclear power with Government > weapons programs." In response to what I wrote: "Not a direct correlation to the civil power industry, " You also wrote "However, to call tritium > permanent and highly toxic is mistaken on all accounts. In response to "but an example of a permanent, highly toxic waste leak that wasn't supposed to happen, and won't get better by itself" Okay, I could have phrased that more carefully. The comment was about the leak in general. If tritium is leaking from the buried reactors and getting into the ground water, you can bet other, highly toxic things are as well. Also: >With a half-life of > 12 years, tritium decays away rapidly which is the reason the Government keeps > wanting to replenish its supply for warheads. Okay, in geologic terms it has an excruciatingly short life span.

Due to the body's ready adsorption of tritium in the form of tritiated water, exposure to tritiated water in air is on the order of 15,000 to 25,000 times more hazardous than exposure to gaseous tritium (HT, DT, and T2). [USDOE; DOE Handbook Tritium Handling and Safe Storage DOE-HDBK-11290YrXXXX-YR p. 5 (December 1991). Available from http://www.eh.doe.gov/techstds/tsdrafts/doe-hdbk-1129-yr.pdf as of July 29, 2006 ]**PEER REVIEWED** Okay, with a biological half life of 10 days, and drinking water repeatedly each day, continuos exposure seems to be a given. And IIRC, the Pacific northwest is rather fond and proud of it's local breweries, so I'm guessing the six-pack will only hurt, not help. > So, reactor embrittlement, like tritium, sound pretty ominous, but neither are > of consequence to the safety of the plant or public.

Over the last 15 years on this list, I can not believe some of the things I have learned that are not directly RV related. I am on other building lists and we may have 2-3 messages a week (all building related)! The other lists are no fun at all. One of the interesting things about this list is the diversity of opinion, thought and experience and I for one enjoy the input. Yes, some of the debate can get tiresome, but where else could you take some of these issues and get the response that comes from an RV builder/flyer/fanatic?

Of course, if I didn't find it interesting, I would have deleted them from my email unread. . . . It seems pretty clear that avgas is going to keep going up with other energy costs. Our current crop of politicians have made it perfectly clear that they aren't going to do anything about it. There doesn't look to be much hope from the next crop either. I had better really enjoy building because at the current pace, I'm not sure how long I'll be able to afford to fly the thing. If they could ever design really efficient, high power density, quick-charge batteries I would love to see electric planes charged by practically free nuclear power.

The rest of the ARROW stuff must be carried but doesn't need to be displayed. See following for the long answer from an EAA Question of the Week... Q & A: Question of the Week Question for EAA Aviation Information Services: I have purchased a homebuilt aircraft from the original builder. It was issued a Special Airworthiness Certificate. Am I required to carry this certificate in the aircraft after the initial test phase of flying has been completed? Answer: Yes, you are always required to carry (and display) the airworthiness certificate in a US aircraft, regardless of what type of certificate has been issued. This is called out in the following regulations: 14 CFR 91.203, which states in part: =93(a) Except as provided in =A791.715, no person may operate a civil aircraft unless it has within it the following: (1) An appropriate and current airworthiness certificate. Each U.S. airworthiness certificate used to comply with this subparagraph (except a special flight permit**, a copy of the applicable operations specifications issued under =A7 21.197(c) of this chapter, appropriate sections of the air carrier manual required by parts 121 and 135 of this chapter containing that portion of the operations specifications issued under =A7 21.197(c), or an authorization under =A791.611) must have on it the registration number assigned to the aircraft under part 47 of this chapter. However, the airworthiness certificate need not have on it an assigned special identification number before 10 days after that number is first affixed to the aircraft. A revised airworthiness certificate having on it an assigned special identification number, that has been affixed to an aircraft, may only be obtained upon application to an FAA Flight Standards district office.=94 **Information on =93Special Flight Permits=94 issued by the FAA can be reviewed in FAA Order 8300.10, Chapter 89. Note that the airworthiness certificate be displayed in the aircraft, as required by 91.203(b): =93(b) No person may operate a civil aircraft unless the airworthiness certificate required by paragraph (a) of this section or a special flight authorization issued under =A791.715 is displayed at the cabin or cockpit entrance so that it is legible to passengers or crew.=94 Also be aware that your aircraft=92s special airworthiness certificate was issued with an attached set of operating limitations. These operating limitations are considered to be a part of the airworthiness certificate, and as such must be carried in the aircraft at all times.

Personnally, I enjoy education whereever I bump into it but some are advised to avail themselves of the delete key if they are not similarly stricken. Hi, Glen, Good comments all. Hanford particularly has some scary environmental stuff out there...and certainly not as well contained as it should be. Billions have been spent and many billions more are in line to be spent to mitigate, not solve the problems. For instance, they have several, million-gallon single walled tanks of suspect integrity containing a witches' brew that will actually boil from the heat generated by the decaying cesium. I think most of this material has been transferred to new double-walled tanks, but there are always residual problems. Hanford has had multiple plumes reach the Columbia River. There's no pretty face that can be put on it. However, the fact that tritium has migrated off of the reservation shouldn't be used as a marker for other, even more hazardous materials. Tritium, because it will not ion exchange with the soil and can not be filtered, is by far the worst migrator and toughest to contain. Even in this circumstance, you would have to drink massive quantities of water from the Columbia everyday, and not excrete any liquids, for a long period of time to even begin to register a potential health threat. Yes, liquid tritium is 10,000 times more of a threat than gaseous tritium, but then, 10,000 times nothing is still not much. If you want to be scared, watch the trucks going down the highway loaded with chemicals or the trains running through backyards that contain massive quantities of toxic, hazardous, flammable and explosive materials. THAT is a clear and present danger. I happen to have beed appointed to the Oak Ridge Site Specific Advisory Board. Our responsibility is to oversee (some would say, second guess) the cleanup activities of the Oak Ridge Reservation. To say we subject them to rigorous, even adversarial, review ins an understatement. While Oak Ridge doesn't have the degree of problem that Hanford does, its still significant. Even then, in the worst case, a person that drank all of his water from the most polluted stream, ate one deer and two turkey's from the reservation, ate 3 fish per week from the stream and breathed the air in the worst part of the reservation 24x7, he would receive a total exposure of 6 milliRem per year. To put that in perspective, the average person in the U.S. receives approx. 350 milliRem exposure from the food we eat, living in a brick house, radon, radium watches, medical procedures, commercial airline flights, et al. While the unknown is often scary, the facts are not. The chemical contamination of our drinking water, including pharmaceuticals, is something to be far more alarmed about than the isolated incident of a small leak of tritium or other radioisotope (though even a small one is inexcusable). Just my thoughts.

It's a very well built, well maintained, attractive, simple, light, fast, day/night VFR airplane. Workmanship, speed, and rate of climb are impressive.

We all know about the food impacts. There is also the fertilizer problem--corn requires more fertilizer than almost any other crop. Fertilizer goes down the Mississippi and contributes to a massive dead zone in the Gulf of Mexico. And natural gas is used to make fertilizer; natural gas is not renewable. Ethanol can't go through the petroleum pipelines, so it is trucked to the pipeline terminals where it is mixed as it is put into the truck. Then there is the energy balance question, which seems to have research supporting both sides. However, not included in any of the research is the loss of gas mileage you get when your burn ethanol. Theory suggests that since ethanol has 70% as much energy per gallon as gasoline you would have a 3% loss of mileage with a 10% ethanol fuel. Experience says this is not the case. I had seen about a 6% loss of mileage in both our vehicles when burning ethanol, but some had claimed as much as a 15% loss. I was skeptical, but now I am not. I recently drove to Colorado to pick up a Lycoming for my RV. With ethanol in Oregon's gas and 65 mph speed limits, I got 15.9 mpg. Outside Oregon, with 75 mph speed limits, I got 18.4 mpg. The higher speeds should have produced a lower mpg. Others have reported similar results but different in magnitude, some higher, some lower mpg loss. I have not seen anyone claim higher mileage with ethanol. These gas mileage losses have not been included in energy balance studies. One expert suggested that ethanol might change the burning characteristics of the blend and might cool things down, giving less power. Suppose we average a 5% loss of mileage. Then we only get a 5% reduction in oil imports, not the 10% that advocates claim. Are all the impacts worth it? Watch your legislatures and stop this virus before your state gets suckered into the ethanol fad.

Ethanol is a bout 71% of gas and Methanol is about 56%. During my racing days I ran d irt track sprint cars both with a gas motor and an alky motor. Gas motor was 10-15 % less powerful then the Methanol motors, The Alky motors nee ded just under twice as much fuel to run the same length race. 40 laps o n a 1/3 mile track burned 25 or so gallons of methanol including all the yellow flag laps. This same race could have been run on 14 gallons of r acing gas...
