The Health Hazards of Not Going Nuclear


This was the first, best book that I read on the systematic benefits of commercial nuclear power over other forms of power production. Petr Beckmann explains all of the benefits of nuclear power in his very characteristic and interesting way. The book was written in 1976, before today's even safer, more efficient fourth generation reactors that are on the drawing boards. The benefits are even greater with the Liquid Fluoride Thorium Reactor (LFTR) – abundant, clean energy for all humanity for millennia.

The advantages of commercial nuclear power boil down to the simple fact that it is a million times more concentrated than chemical energy. Burning coal, oil or gas involves the energy associated with the electrons of the fuel, measured in electron volts. While nuclear power involves the energy in the nucleus of the fuel, which is measured in millions of electron volts. Thus, nuclear energy is a million times more concentrated than fossil fuels and it produces a million times less waste.

The only question is whether or not I will see a LFTR in the US in my lifetime. They will almost certainly be built in India, China, Brazil, South Africa, and Russia. Why not here?

Four Great Engines for Small Aircraft







Sport Aviation (February 2010 issue) http://www.eaa.org/experimenter/articles/2010-02_powerplants.asp ran a great article on VW based aircraft engines. The four companies that were featured are listed below:

Revmaster Aviation
7146 Santa Fe Avenue
East Hesperia, CA 92345
Phone: 760-244-3074

Great Plains Aircraft Supply Company Inc.
7011 N. 160th Avenue
Bennington, NE 68007
Phone: 402-493-6507

AeroConversions
P.O. Box 2521
Oshkosh, WI 54903-2521
Phone: 920-231-8297

Hummel Engines & Machining LLC
5464 East Storey Road
Coolidge, AZ 85228
Phone: 520-723-5283

I would love to have a Kitfox Model IV - 1200 with one of these on the front with a great wooden propeller. I think this combination would be one of the most economical two seat aircraft in existence. (One plane that would be more economical is the single seat, ultralight Legal Eagle XL, with a two cylinder VW engine.)

Populus to Ben Lomond Transmission Line











Pacificorp is building a 345KV, double circuit power line, that runs by my house, to transmit electrical power from their Populus substation north of Malad, Idaho to their Ben Lomond substation near Ogden, Utah. I took a hike with my son yesterday, since I wanted to see the power poles up close and because it was a good excuse to get out of the house and see a little blue sky and sun, even if it was still below freezing.

The transmission towers are a marvel of engineering. The highest tower near my house stands 155 feet above the ground and weighs 47,556 pounds. Here is the actual placard that is on the pole:
The line covers 135 miles, so that means there are hundreds of poles. This is obviously a very expensive project, whose merits I am not questioning. I would just like to point out that it would be neat to see a disruptive technology that would obviate the need for these large, interstate transmission lines.

Imagine small liquid fluoride thorium reactors (LFTR), so economic that every city of 20,000 or more could have one of their own for all their electric needs with enough waste heat left over for district heating of the entire town with heated streets for snow removal. I know, I know, I’m day dreaming again.

A step beyond that would be zero point energy (ZPE) devices compact enough to fit in a car and provide 50 KW. I know that ZPE is all very speculative, but how long did it take humanity to invent suitcases with retractable handles and rollers?

Since molten salt reactors have already been built and operated for periods of years, LFTRs are in no way speculative. This is technology that we could have today. And I believe that LFTRs would be very disruptive for the current players and a godsend for the rest of us. So, lets disrupt!!! Every garage inventor, every Tesla, every Newton, every Galileo, every Scaliger, every Rutan, every Paul Allen – come on, we need you to disrupt! We especially need disruption of the sclerotic bureaucracies and fear mongering pressure groups that have thwarted peaceful nuclear power since the beginning!

(As an aside, I scaled a photo of the 155 foot tower to measure the distance to the next pole and calculated 886 feet. Assuming the same spacing between the rest of the poles, 135 miles times 5,280 divided by 886 feet equals 804 towers. That’s a lot! This transmission line project is one of nine Pacificorp projects totaling $6 billion. Couldn’t a utility easily develop a LFTR for a cool billion dollars?)

Dreams Versus Reality

This was my dream airplane when I was 10 years old. I drew it myself on a 4 hour trip from Elko, Nevada to SLC, Utah, somewhere between Wells and Wendover. I modeled it after the B-25. Of course, it was big enough for the whole family and probably some neighbors too.


Next, when I was a teenager, this was the airplane that I loved. I had a subscription to Flying magazine, which I used to drool over and the Bonanza was featured regularly on its pages. I think the cost of a new one today is a cool 3/4 of a million dollars and they say that the nose gear doors still don't close completely.

Now that I am middle-aged grouch (according to my wife) this is what the dream has turned into - reality. A Cri-Cri. This is the kind of flying that I can afford.
I'm being a little bit facetious about the Cri-Cri, but not much. Seriously, I hope to soon have some good news about a plane (still extremely modest) in the near future. Stay tuned.

LFTR Fuel Cycle

I lifted this from Kirk Sorensen's blog. It shows the simple and robust fuel cycle for the Liquid Fluoride Thorium Reactor. This is truly a gift from nature!

Liquid Fluoride Thorium Reactor

I recently discovered a 60 year old treasure. It's called a Liquid Fluoride Thorium Reactor. I read about it in the current issue of Wired magazine, which referred me to a blog by Kirk Sorensen called Energy from Thorium. I heartily recommend his blog. He gave a tech talk at Google last year that I also recommend along with the PowerPoint presentation that you can down load at http://www.energyfromthorium.com/ppt/Sorensen_Google_20090720.ppt.

This reactor is even better than the 4th generation light water reactors and even General Atomics 4th generation gas turbine reactor. Less waste, less cost, even greater safety! I wish I could buy one!
