Ibuprofen May Cut Alzheimer's Risk - WebMD, 5/5/08 -
"Use of ibuprofen pain relievers like Advil and
Motrin for more than five years reduced
Alzheimer's risk by 44% in a study reported in the May issue of Neurology"
CoQ10 may cut muscle injuries for athletes - Nutra USA, 5/5/08 -
"The volunteers had daily training sessions of five and
a half hours per day for six days during the intervention period. At day three
and five of the six day training period, the researchers report that both groups
experienced increased in serum creatine kinase activity and the concentration of
myoglobin, but these increases were significantly lower in the group receiving
the CoQ10 supplements ... Elevated levels of
the enzyme are indicative of muscle damage and injury ... levels of lipid
peroxide, a marker of oxidative stress, were also lower in the CoQ10 group after
three and five days of training" - [Abstract]

Your
Keyboard: Dirtier Than a Toilet - ABC News, 5/5/08 -
"It turns out that your computer keyboard could put a host of potentially
harmful bacteria -- including E. coli and staph -- quite literally at your
fingertips ... one had levels of germs five times
higher than that found on the toilet seat" - Note: I put my
keyboard in the dishwasher every once in a while. It takes about a week
before it will work again but I haven't had any go bad yet. I've got
several keyboards from old computers so I don't care if I lose one. Also

Neat Tech Stuff:
There was a
segment on the San Diego local news regarding
natural gas powered Honda
Civics. They claim the equivalent comes to $1.25 per gallon as does the
Jay
Leno video. Both the Fox6 video and Leno video claim $1.25 per gallon
equivalent but I think they are talking about the
home units because the SDG&E
plump says $2.67 per gallon equivalent put Poway Unified School has a pubic pump
measured in therms at $2.00 per therm. I calculate that to be $1.75 per
equivalent gallon which seemed about right for the mileage (1
gasoline gallon equivalent (GGE) = 114,118.8 BTU's = 1.14 Therms). I
bought the last
2008 that my local dealer
had because someone cancelled out. The price is around $25000 however that
price is very practical when you look at a few things. First there is a
$4,000 federal voucher off you federal taxes. That's a voucher not a
deduction so that brings the cost down to $21,000. Plus I was only getting
25 MPG with my Ford Focus. With a previous Escort I was getting 33 MPG.
I'm figuring 30 MPG with the Honda. I did the math figuring how many miles
I've averaged per week, per month and per year since I bought the car and
calculated the savings on gas to be $1560 per year. That's adds up to
$7800 over a five year period. If you subtract that from the $21,00 it
brings it down to $13,200 but it's probably better than that. I used to
live in Coronado, CA but now live in North County. Anyone familiar with
San Diego knows that people in North County put on a lot more miles. If
you figured I averaged 50 per week less in Coronado and 50 miles more per week
in North County (8.3 miles more per day in North County) which is probably what
I'm driving now the 5 year cost savings on gas would bring it down to $11,700.
On two tank full's I averaged about 35 miles per gallon on mostly highway
driving. The sticker says 24 city, 36 highway but I've never gotten
anywhere close to those numbers with any other car. (35 - 25)/25 = 40%
more mileage than my Focus. I used to get high test (called premium for
the younger generation) for the Focus for at $4 per gallon. So even
without the lower price of natural gas, that's $16 less than the Focus for a 10
gallon fill up but high test is $4.12 now so it's even better. Figuring
$1.75 per equivalent gallon of natural gas and $4.12 per gallon for high test
gas and using 40% better gas mile the savings would be ($4.12 - $1.75) * 10 *
1.4 = $33.18 per 10 gallon fill up but if the home refueling unit brings the
cost of natural gas down to $1.25 it would be ($4.12 - $1.25) * 10 * 1.4 =
$40.18 per ten gallon fill up. If you used that 10 gallons per week (250
miles per week in my Focus) it would come to $40.18 * 52 = $2089.36 saving per
year for the Honda natural gas at 35 MPG over the Focus at 25 MPG. That's
$10,446.80 over ten years so you can see how the savings can add up. I
think there must have been something wrong with the Focus that I only got 25 MPG
though. Whatever it was, it may have souped up the carburetor because it
had the power of at least a 6 cylinder. That $2089.36 savings per year
would take $174.11 off the monthly payments.
The
Leno video claimed that refueling from your home cost $1.00 to $1.25 per
gallon equivalent and that having a home refueler locked you in at the baseline
rate. I tried to get some hard numbers on that.
Click here for my last San Diego Gas & Electric
bill. I couldn't figure it out but the bottom line is that 38 therms came
to $54.61. $54.61/38 = $1.43 per therm. $1.43/1.14 = $1.26 per
gallon. So those public natural gas pumps must be making a killing with
their markup. Maybe that will come down as competition picks up.
There is a natural gas trip planner
on the Internet. If I went to Las Vegas I'd have to get fuel in Barstow
and then Las Vegas has several places. As far as Los Angeles, I could make
it there and back on a tank easily plus there are several places in LA plus you
can print out the gas stations from the Internet and put them in the GPS and
find them easily. San Diego has only 11 refueling stations but one is only
about 2 miles away but I wouldn't need it with the garage refueler.
Another problem is that you only get about 225 miles on a tank. The
problem in San Diego is that they are sold out until the 2009 models in
September.
It's estimated that demand will outpace supply of oil by the year 2023. I
would think that the US would have to start switching to an alternative at least
5 years prior to that. I don't see any other option than natural gas.
With bio-fuel it used to take more gas to produce it than what you got.
Now it's a little less but not much. They keep saying that they can get it
down to something like .3 gallons per 1 gallon produced but I don't see it
happening at the rate their going. It seems like the people saying that
are the ones getting paid to do the research. Plus one of the reasons the
price of food is going though the roof is because of the crops being used for
bio-fuel. Plus
Time Magazine is saying that bio-fuel might even make global warming worse.
Plus I believe that we will run out of fresh water to grow enough bio-fuel.
Plus bio-fuel thickens at low temperatures kind of like when you put olive oil
in the refrigerator. Yeah, you can heat the fuel tanks but that's even
more energy and another obstacle. Yeah, I read about the
Jatropha plant years ago.
It's supposed to grow nearly anywhere with very little water. They know
the numbers don't add up on that so they argue that they can grow it in poor
countries and pay low wage to pick Jatropha seeds. Sounds like code for
the equivalent of childhood sweat shops paying kids 3 cents per day so people
can run their SUVs. It might be outside but it's just as hot. I was
going to buy stock in the main company producing it but had second thoughts the
more I read. If it was viable, why are we wasting our time with corn and
soy? Just doing rough calculations there is no way the numbers ad up.
I calculate that Jatropha will yield 5600 gallons per square mile per year (Slide
13 and doing the math). There are
3,537,441
square miles in the United States. So if planted every inch of the US,
which is impossible with the lakes, road, building, etc., you would get
19,809,669,600. So let's say 20 * 109.
Then let's say 200 million people in the US average 20 gallons per week.
That's 208 * 109. (that's less that the
284 * 109 that this site claims is
the actual number in 2002 which shows how close my guestimates are).
That's still less than a tenth of what we need, probably about a twentieth of
what we need growing every inch of the United States with Jatropha which is
impossible. Even with 8th grade math the numbers don't come anywhere near
adding up. You can't grow the equivalent of millions of years of dead
dinosaurs.
When we switch, I don't know why anyone would go with hydrogen when I'm betting
the natural gas cars will be a lot cheaper and will cost less than half to fuel
compared to hydrogen. I'm putting my money on it with my
Honda GX and investing in the Phill
natural gas refueler for my garage. I called the cassette/8 track war
(you really have to be old to remember that one) then VHS / beta war (at least
we're up to the '80's). I called CD's so fast that I went out and bought a
player and it was a good two years before there was any kind of selection.
I was starting to wonder if I could have been wrong on that one. Then Blue
Ray / HD DVD war. I'm calling natural gas as my bet on the automobile
alternative energy war. Hydrogen might be sustainable but I'll bet it will
be 40 years before it is price competitive again natural gas plus it seems like
we are already behind the eight ball in planning power plants to produce it.
There are so many problems with hydrogen that I don't see it happening in my
lifetime. First of all, it takes up so much space that the only practical
way is to compress it into a liquid. To get hydrogen from water into
liquid hydrogen requires a tremendous amount of energy. Where is that
energy going to come from unless they increase the amount of nuclear power
plants by at least 30 times? Plus fuel cells require a rare metal which
will become even more rare if we start producing fuel cells. They keep
saying that we should be able to find a substitute but what if they can't.
Plus the hydrogen atom is so small nothing will hold it completely. The
best they've been able to do is still losing 1.7% per day / 51% per month or
half a tank due to leakage. That's a huge loss in energy everyday when you
figure the total number of cars for something that already required a huge
amount of energy to produce. Plus that's just not half a tank for you it's
all the way down the line. For example, if the gas station has a 30,000
storage tank and loses half that a month. If the oil companies try to
store liquid hydrogen in those huge storage tanks, not only will they need to be
four times as large or four times as many to hold the same amount of energy but
they will lose half that capacity every month. Plus the tanks to hold
liquid hydrogen are going to cost way more than the ones that currently hold
petroleum. You can see how fast that loss can add up and how that could
add to the price. If we are going to come up with the nuclear reactors to
produce all that hydrogen we are already late. It takes something
like 12 years to get them on line.

Hydrogen
- stanford.edu, 3/30/08 - "the disadvantage is that
it needs about 4 times the volume for a given amount of energy [liquid
hydrogen - gaseous is much much worse] ... Since the insulation can't be
perfect, the hydrogen will gradually evaporate, typically 1.7 percent per
day ... 2.12 times as much energy goes into generating and transporting
liquid hydrogen by truck than you get into the fuel tank of the car"
-
The Fuel Cell: Now, and in the Future - altenergystocks.com -
"Fuel cells are very expensive, not due to the fuel use,
but due to the materials required to capture the electricity. Electrodes used in
the circuitry are usually made up of platinum, a highly expensive and rather
rare metal. Sometimes, fuel cells require membranes to separate their
electrodes, and these membranes are very costly"
From what I've read, solar energy cost about 3.5 times
today's current rates. That might be an option to produce hydrogen but can
anyone think of increase their home utility bill by 350%? With solar
panels it takes 4.5 year just to get the energy back that it took to manufacture
them. Those people you see on TV that claim they are saving money are
doing some kind of voodoo math. I got prices from a San Diego dealer when
I was president of a homeowners association and did the math and there was no
way it even came close to be cost effective.
I read one article that claimed wind power was only about 10% higher than
today's rates so that might be a better option is you can install enough of them
but that's something that will take many many years. However, an article I read
a few years ago said that wind cost 40 cents per kilowatt which is about a 10
times higher.
Electric cars are a joke. Every time you change energy from one form to
another you lose a large percentage. With electric cars you start with
chemical energy in the form of natural gas at the electrical generation plant.
Then you change it to heat energy (combustion) to turn the turbine generator (kinetic
energy) which turns it into electrical energy which goes through wires (more
energy loss) which charges the car batteries (chemical energy again?) then back
to electrical then back to kinetic energy to move the car (I count 6
conversions). With natural gas you're just going from chemical to heat to
kinetic energy (2 conversions). That's got to be more total energy plus
you're just moving the pollution from the highway to the power plant.

Energy Rules! Energy Conversion and the Laws of Thermodynamics - Energy
Conversion Introduction - uwsp.edu - "The amount
of usable energy that results from the conversion process (electricity
generation, lighting, heating, movement, etc.) is significantly less than
the initial amount of energy. In fact, of all the energy that is
incorporated into technologies such as power plants, furnaces, and motors,
on average only about 16 percent is converted into practical energy forms or
used to create products. Where did the other 84 percent go? Most of this
energy is lost as heat to the surrounding atmosphere" - I'm wondering
if they have those numbers crossed. I remember something like a 40%
loss per conversion in college but thought that was decreasing to 20% but I
couldn't find any other sites that gave actual numbers. I know I've
seen furnaces advertised as being efficient in the high 80 percents.
The only other site I could find said
a
fossil fuel powered electric generating plant was 40% efficient.
That makes sense, 3 conversions (chemical to heat to kinetic to electric -
.75 * .75 * .75 = .42 or 42%). So electric cars (chemical to heat to
kinetic to electric to chemical to electrical to kinetic - .75 * .75 * .75 *
.75 * .75 * .75 = .13 or 13% efficient not counting the loss in the
transmission wires from the electric company to where ever the car is
charged which is probably another .9 in the equation). For natural gas
cars (chemical to heat to kinetic - .75 * .75 = .56 or 56% efficient).
Not good but a lot better than 13%. The point is that every time you
convert there is a significant loss therefore electric cars can't be very
efficient at conserving energy.
We've got enough natural gas to last 250 years. If we start using it for
transportation it will probably cut that down to about 30 years but that's still
30 years of bought time. In the mean time people need to rid their love of
the SUV and start using Energy Star products and energy efficient bulbs.
Hopefully they will figure a way to produce energy with
fusion but that may
never happen. Plus natural gas primarily consists of methane and methane
is the
primary cause of global warming. It seems like they could increase
that 30 years substantially by
harvesting methane from animal and human waist. You're not going to
extend it indefinitely. Just eye balling it one movement per day is not
going to power my car for a day. Methane is
20 times more powerful than carbon dioxide as far has global warming so
harvesting it and turning it back into carbon dioxide and water by using it as
fuel would seem to cut down on global warming by a factor of 20. Cutting
down on something by a factor of 20 that would have ended up in the atmosphere
anyway sounds like a better option than even zero global warming fuels.
The bottom line is that I feel natural gas will win as the alternative fuel
source for anyone old enough to be reading this newsletter.
Everyone wants to blame high oil prices on those evil capitalist oil companies.
Those oil companies have about an 11% profit margin. That’s about a third
of what Microsoft is. How much profit do people think the oil companies
are authorized? Yeah, 9% would be better but do people really think that
2% off the wholesale price is going to make a difference? Maybe we should
deny the oil companies any profit at all so that there will be no incentive to
find more cost effective ways to do things and gas would be even higher.
Better yet there wouldn't even be any incentive to find oil. Then we could
do like the old Russia and send the company presidents' families to Siberia if
they don't find oil. Yeah, that's the ticket. People that think
there's a better system might want to looks at the price of gas in other
countries that import their oil. I don't know why so many people are in
denial that we're running out of oil and I don't know why there is so many
paranoid schizophrenics that think everything is a conspiracy. The problem
is not the oil companies, it’s that we are running out of oil and despite the
snow job on alternative energy there are no solutions that are even close to
being easy. Those people should be criticizing people with SUVs and people
who are still using incandescent bulbs and people who aren’t buying Energy Star.
Yeah, oil companies make billions but that’s because 11% of a lot of money is
still a lot of money. These are huge companies. Politicians who
criticize and claim they have a magic fix are lying. Tapping our oil
reserves will just make things worse further down the line plus there's only 58
days worth in the reserves putting us in a really bad position if there's
another embargo. Those of us in the '70's remember the gas lines. I
was in college and remember studying while waiting in the lines. At least
you were usually able to get it if you waited long enough and it was an odd or
even day according to your license plate and they didn't run out while you were
in line.
It sure doesn't seem like our leaders have all this calculated out. They
haven't even eyeballed it or they would see what a terrible situation we are
going to be in in a couple years if they don't come up with the power plants to
produce all this hydrogen.
I feel I'm at least doing something by plugging natural gas cars. Whatever
alternative fuel we go with, wasteful use is still going to hurt our environment
even if it's hydrogen produced my nuclear energy. You still end up with
the nuclear waste. Plus we shouldn't build anymore nuclear reactors than
what we can barely get by on.
I'm not an expert on alternative energy. All the above is basic stuff yet
the overwhelming majority of people are not even acutely aware of the problems.
I feel there is a bad moon rising with the energy crisis and no one's paying
attention. I worry that world leaders have hugely underestimated the cost
of a hydrogen economy and that when we are forced to switch those costs will put
us in a world depression worse than that of the '30's. For that reason I
question whether it should be legal to be wasting petroleum on SUVs and travel
homes getting 4 miles per gallon. It took the government this long to
figure out that bio-fuel wouldn't work something that should have been obvious
from the beginning based on fresh water along.

Why whole grains are protective: biological mechanisms - Proc Nutr Soc
2003 Feb;62(1):129-34 -
"First, whole grains are concentrated sources of
dietary fibre, resistant starch and oligosaccharides, carbohydrates that
escape digestion in the small intestine and are fermented in the gut,
producing short-chain fatty acids (SCFA). SCFA lower colonic pH, serve as an
energy source for the colonocytes and may alter blood lipids. These
improvements in the gut environment may provide immune protection beyond the
gut. Second, whole grains are rich in antioxidants, including trace minerals
and phenolic compounds, and these compounds have been linked to disease
prevention. Additionally, whole grains mediate insulin and glucose
responses. Although lower glycaemic load and glycaemic index have been
linked to diabetes and obesity, risk of cancers such as colon and breast
cancer have also been linked to high intake of readily-available
carbohydrate. Finally, whole grains contain many other compounds that may
protect against chronic disease. These compunds include phytate,
phyto-oestrogens such as lignan, plant stanols and sterols, and vitamins and
minerals."
-
Whole grains protect against atherosclerotic cardiovascular disease -
Proc Nutr Soc 2003 Feb;62(1):135-42 -
"Generous intake of whole grains also provides
protection from development of diabetes and obesity. Diets rich in
wholegrain foods tend to decrease serum LDL-cholesterol and triacylglycerol
levels as well as blood pressure while increasing serum HDL-cholesterol
levels. Whole-grain intake may also favourably alter antioxidant status,
serum homocysteine levels, vascular reactivity and the inflammatory state.
Whole-grain components that appear to make major contributions to these
protective effects are: dietary fibre; vitamins; minerals; antioxidants;
phytosterols; other phytochemicals. Three servings of whole grains daily are
recommended to provide these health benefits"
