Replace Hockey Stick
Tape with
Rubber Paint
Try Rustoleum Rubber Undercoating
Spray Paint on hockey stick blades instead of using tape. Tape randomly comes off resulting in
an inconsistent feel. Some players have to retape their
blades every 2 or 3 games.
We spend a lot of money trying
to get the lightest stick possible, and then we add weight by adding tape
and wax to our blades. Why not just spray paint a layer of
rubber paint on our sticks? I tried it: I can now hit posts and
crossbars, sometimes intentionally.

Electric Bicycle, No Pedals!
Powerful electric
bicycle with 2 electric hub motors gets about 3
miles a penny and is better for the environment than driving a car.
Some people might be
able to avoid driving a car in congested traffic with a no-pedal
ebike. It's an ebike so you won't arrive at work all sweaty like you
might on a regular bike.
Here is the story of a
ground loop
geothermal heat pump I installed at my home
which provides both low cost heating and air conditioning. Click the picture to find out why and how
I installed this cost-saving environmentally friendly system.
Grid Tied
Solar Tree House
Chart
the falling
prices of photovoltaics and it
becomes
obvious that solar panels will help solve our problems with energy and
climate
change. So I added grid-tied solar panels to my home and now can enjoy
watching
the electric company's meter spinning backward on sunny days. By
installing it myself, I was able to get a payback of about 5 years.
With zero maintenance costs, it's now making free money for me.
I
actually found
this idea on the internet. I modified it
and my wife found our septic tank at our camp on Sebec lake with it.
Click the picture to read the story about how we finally found the tank
with this device after all other methods failed.
You can
buy personal plows at places like Home Depot. I don't know what I would
do without mine. It beats snowblowing my
300 foot driveway and definitely beats paying someone who may or may
not show
up to plow my driveway. Unfortunately the plow puts a high load on my
Ford
Escape's front end 2" hitch which can bend the hitch downward. This
unusual fix with a strap is surprisingly strong.
Skate
Sharpener,
Home-Built
I try to
play
hockey twice a week year round and I like
sharp skates. Rather than pay $5 to $10 every few weeks to get the
edges I
want, I
opted to build my own skate sharpener. I've used this $150 setup for
about
twenty years and saved over $1700!
Click
the picture to read the story about our solar-powered canoe
with wheels. There is nothing like quietly and effortlessly motoring
along the Stillwater River in Orono, Maine and observing (sneaking up
on) the
birds and beavers and other wildlife that live there. The portable
light-weight
wheels are mounted on with straps that go across the bottom of the
canoe holding the two wheel assemblies in the right place. The wheels
can be left on when in the water and can be used to provide extra
stability when plastic bumpers are strapped to the outside of the
wheels. The left and right wheel assemblies don't take up
much room, so they can be stowed away for long trips involving
multiple portages. Although I haven't tried it yet, the wheels are
designed to be mounted or taken off when in the water.
SUV
Roof Tent
This is the story about a cool, clean and
practical way to go camping.
Build a top rack that unfolds into a
7'X7' tent platform with a hole in it for climbing through the sunroof
and into a low-cost Coleman 7'X7' tent. There is room for a queen size
mattress and other things in the tent. The tent and foam mattress fold
up and are easily stored inside the SUV when travelling. The platform
folds up and can be used as a top rack for a canoe or kayaks.

400 NMR
donated to University
Many called about this free $100,000 NMR
when it
was
posted one evening in an NMR newsgroup. I just happened to be first to
realize
its value and say yes, we definitely want it. Its been an essential
University
research tool. We throw away so much in our society and spend so much
on the latest newest fad. Wouldn't it be better for the environment and
our budgets to recycle and spend wisely. For example, people throw
away computers because they have a virus that slows them down.
Why not just reformat
the hard drive. Even a Windows XP box with Deep Freeze software that
restores the PC back to a pristine state after each use, can keep an
old
computer functioning productively for years if not decades.

Physics
of
Learning
Do Students Obey the Laws of Physics?
As teachers and learners, we use
terms applied to our physical world to help us explain and discuss our teaching and learning
experiences. For
example: "Students should pass in their work on
time.
Teachers develop optimum
learning paths. I ran out of energy
studying last night. We
had a heated discussion. I’m going to force
myself to learn this." Can we learn more about
teaching and learning by carrying this analogy
further? An interesting exercise is to utilize the rich resource of
terms and
mathematical relationships
in
physics. Extending the analogy this way may help science teachers
define
pedagogical parameters and more fully understand the relationships between
those parameters.
Ring
Diffraction Spectrometers
Introduction
to Ring Spectrometers. How to make a spectrometer that measures light
intensity versus wavelength. It utilizes a ring
diffraction
grating made from a CD or DVD and a webcam. The picture shows a
circular
rainbow spectrum produced by a common CD with light from a fluorescent
lamp. You can see the mercury lines and the broader spectrum from
the phosphors of the lamp. I thought this was so
cool, I patented it.
Scientists
and Engineers
IGF:
Interactive Gaussian Fitting Program
Spectroscopic
data often produces overlapping peaks where each fits the mathematical
formula: I= Io e -k
((X-Xo)/w)2
where Io is the intensity of the peak, Xo is the position of the peak,
and w is the width of the peak. There are numerical analysis programs
for determining the peaks and their properties, but I prefer to see
what is happening as I am analysing the data. This visual and
interactive approach is what the above program does. Check out the Help
file for more info. This Windows program will take text two column,
intensity and wavelength, CSV files and
find the peaks using a best guess, iterative approach. Click to
download.
MIST: Mass
Identification Smart Tool
Input
a chemical mass from a mass spectrometer into this Mass Identification
Smart Tool and it will search for all possible chemical combinations
that add up to that mass. For example, enter 120 as shown above and the
program will output the compounds shown on the right in the picture.
This Windows program utilizes chemical fonts, ChemSerif.TTF and
ChemsanSerif.TTF, that must be installed in your Windows Font folder.
You will probably have to restart Windows to properly install them. To
save processing time, the isotope library can be shortened and altered
so that only the relevant elements are searched. Click to download a
zipped folder that contains all the needed files and run the setup

"QED,
The Strange Theory of Light and Matter" by Richard Feynman is one of
the most amazing books I've ever read. Most physicist take quantum
mechanics and are told to not try to understand why our quantum world
is the way it is, just do the math. Feyman admits Quantum
Electrodynamics is strange right in the title, but he goes on to give
an amazingly simple description of QED, and the way our world works, in
terms of processing all possible paths to determine how something might
happen. Well computers are good at doing repetitive things like
analyzing all possible paths. That is what my QED program does. Where
will a photon go after it hits four narrow parallel mirrors? The image
show the statistical probability of where that photon might end up.
It's a diffraction pattern, something similar to what you might see
when you squint your eyes while looking at a distant bright point light
source. You can change the mirrors and positions and distances in the
program. Oddly enough, heavier particles like electrons, protons and
atoms also produce similar patterns. The program is visual and both
interactive. Click to download this Windows program.
Visual NMR
VisualNMR.exe
is an NMR simulation program I wrote to teach basic Nuclear Magnetic
Resonance concepts. NMR is the most important instrument chemists have
for identifying organic chemicals.
Most universities and large companies that deal with organic chemistry
have at least one NMR. MRIs used in hospitals are a type of NMR. Bad
results and poor decisions can happen when an instrument user doesn't
understand how an instrument works. The instrument becomes a mysterious
black box that magically produces data. This is a form of Garbage In,
Garbage Out. So I wrote this program so that users can see what is
happening when they do NMR, and the general effect NMR parameters have
on their data. I also added some interactive visual game options
to the programming that make learning NMR fun. Click on the image

program, VisualVnmrJ.exe written for a Varian NMR. Click Help in the
program for more info. Contact

Journal
of Renewable and Sustainable Energy 4, 013111 (2012); https://doi.org/10.1063/1.3683527
Due to
the rising demand for low-cost clean energy, the
development of efficient wind and water energy-generating systems is
one of the major goals of this century. A novel approach for extracting energy efficiently
from wind and water currents utilizes a tail-weighted wing following a
figure-eight trajectory. Our prototype consists of a vertical
ribbon-type wing suspended at its endpoints by swivel bearings. Energy is
extracted from the longitudinal pumping motion that
occurs at the endpoints of this flexing wing. Since the forces in these
wings are in tension like a suspension bridge,
the design can potentially be scaled up to much larger sizes than
current systems and sweep across enormous areas of moving fluid with
a relatively small amount of material. High-speed photography is
used to map out the trajectory of a prototype wing and to monitor water flow around
the wing. These observations along with data from an interactive computer simulation program
are used to study the vortices and hydrodynamic forces
that propel the wing along the figure-eight trajectory. Our prototype
is low-cost, simple to fabricate and extracts a high amount, 30%, of
the total energy in the
water that flows through it.

Does this graph scare you?
In 1972, an MIT
study predicted pollution would increase as shown by the blue line.
The red line shows
how much Global Warming Extreme Weather Events have cost us so far.
If we continue the business as usual approach, global warming could
lead to the collapse of civilization in 2050. Unfortunately many in the
US have been manipulated by fake news
networks into thinking this is a hoax. That's because they use a
Passive rather than an Active Approach to
obtaining the
news of the day.
Many of us digest our news in an old-fashioned
passive way.
In the old days, we relied on a single newspaper or TV news station to
get our
news. We relied on these news outlets to responsibly select news that
would be important to
us. They had their reputations to protect and they knew that being
truthful and
honest was the best way to get more viewers. These
days this passive approach to obtaining
news exposes us to being manipulated by less trustworthy actors,
pretending to
be knowledgeable, caring and patriotic. In reality, their job is to
prioritize the manipulation of
people for their own profit. They select and spin news stories and
topics to promote their own
agenda. They often make people act and vote against their own best
interest. These
mass manipulators don’t want you to actively think for yourself. They
design
their news shows to force you to passively think and feel what they
want you
to.
Fortunately there is a way to avoid these
manipulators. In the age of the internet,
it is easy to actively
follow up on a news story and to discover all perspectives of a news
story.
Just Google it or go to Wikipedia and ask questions about the topic
some news
manipulator presented to you. For example, some news channels might
state that
Trump is a criminal. You have your doubts, so you Google it. “Is Trump
a
criminal?” Try this one: “Did thousands die of Covid because Trump
didn't want
people to wear masks?” Or how about “Did we really land on the moon?”
If you are
not sure if my graph is scary, why not Google: “Is
Global Warming a hoax?”
That’s the active approach to getting the news. Just
Google
it or check it out on Wikipedia. Actively getting your news is the
patriotic
thing to do. Being manipulated by others is not. Knowing the truth is
the best
way to make good decisions for you and your country.
I think that graph is truly scary. But don’t rely on
me for
that. Google it and find out for yourself.

Misinformation
Our nation has a
serious misinformation problem:
Our
Brave New World has
misinformation reinforcement mechanisms that reinforce the convictions
of the misinformed. In the old days we would rely on the credibility of
major newspapers and a few major news channels like CBS News, NBC News
and ABC News. These news outlets had their reputations to protect.
Errors in news reporting was news in itself that resulted in damage
to their reputations and loss of market share. Modern technology
brought with it cable news and then internet news. These formats don't
compete for large market shares. They only need to appeal to a limited
market of believers. This amplified the output of propaganda news,
unchecked "news" that was not based on reality as much as
reinforcing the beliefs of its viewers. Slick, colorful,
emotional and sexy "news" became more important than real news. These
news outlets could convey any message they wanted, and usually served
the interests of the rich and powerful rather than the worthy goals of
a democratic people. More people became enslaved as they worked harder
for less, yet they continued to vote against their own best interests
under the influence of unchecked propaganda news.
The word "News" implies a meaningful
contract between the news service and the viewer. The viewer assumes
the information presented is verifiable and presented without bias. As
such, news shows should not have free speech rights. Shows that offer
opinion labeled as news should be held liable for the damages they
cause. For example Fox News should be held liable for the
misinformation they have spread about Covid-19 and voting machines.
News shows that are really opinion shows should present a warning label
at the start of their shows, much like the
warning label on a package of cigarettes. The warning should include a
record of when and how often the commentator has been proved wrong. If
a commentator reported that Covid was a hoax and their reporting
resulted in many deaths, every subsequent report of theirs should
include a suitable warning. Warning: This commentator has made false
comments about Covid that have resulted in multiple deaths.
Protecting
America’s democracy requires that we get our news from reputable
sources. Learn about which news sources have the best records on truth

Predicting the Future
There is a lot of money to be made if
one can correctly predict stock
market trends. But trying to predict the future is a challenging
exercise. Our predictions are often wrong. In any case, here are
some
of my predictions.
Is the
USA getting weaker?
Yes, due to tariff wars and
incompetent leaders ignoring the advice of experts.
Are
Americans less free?
Yes. A few super rich oligarchs can now buy
elections and manipulate
politicians into creating a society with an inflated cost of living,
where money from the many trickles up to the hands of the few.
The result is that oligarchs have created a society where many Americans are
enslaved by the threat of going broke. Americans everywhere are now paying more for less,
and approximately 70% of them are now living paycheck to paycheck. Oligarchs have found ways to extract money from many aspects of our society by privatizing government programs and halting progress on programs that might cost-effectively serve the people. For example, health
care has middle-men insurance and drug companies extracting wealth from
the sick and dying.
Housing has speculative investment firms inflating the cost of housing.
Money from these businesses ends up in stocks and ultimately gets into the
hands of the top 10%
who own 93% of the stock market. The US
Constitution, the Bill of Rights and our laws are also being ignored.
The USA is now
becoming
more like Russia with closed borders (you can leave but will they let
you back in?) and with new restrictions being placed on
voting rights.
When will
America become stronger and the stock market rise?
When inflation becomes intolerable,
consumer spending will collapse and the economic engine that trickles
money from the many to the few will stall. The misguided supporters of the current incompetent administration will finally realize
they have been manipulated and robbed
when they see oligarchs coming after their social security and medicare
money. They will realize the real purpose of tariffs is to tax the many
and redirect that money to the few through tax breaks for the
rich. As America gets weaker and the
oligarch society faces collapse with the threats of tariffs and real
wars and a coming
economic depression, these oligarchs will lose their motivation to
manipulate and rob the masses. I predict new leaders and others (like
Bernie
Sanders) will create a Save the
Nation Plan in 2028 (click here to see some ideas for a plan)
to repair the damage and
establish new
and fair trade agreements with the rest of the world. The plan will bring back
and
enforce the US Constitution and the Bill of Rights as guides for making
the US strong and stable again. It will fairly
tax
businesses like oil companies for the environmental damages they have
caused, and it will regulate or replace health insurance and drug companies that
have over-charged for the cost of health care. It will make the
super rich pay their fair
share of taxes again which will help lower the budget deficit. I predict the stock
market will continue to decline for the next two to four years until a Save the Nation Plan is implemented.
This plan will restore global trading and world stability, and stop inflation. That will be the time to buy stocks if you can.
