Include Solar Water Heater Plans for Your New Home
Solar Hot Water
Solar hot water heating systems are an effective way of
conserving energy and reducing your energy bill.
Contrary to popular belief, solar water heating is not a
new technology. Solar water heating systems have been used
commercially for over a century now, with the first
commercial water heater (the Climax Solar-Water Heater)
going on sale in 1891 in the United States. By the year
1900, over 1600 houses in California were equipped with
this solar water heater.
Due to its effectiveness and low cost, the solar water
heating gained popularity until, by 1941, more than half
the population of Florida was getting its hot water through
solar water heaters!
Solar water heating only lost its popularity as a result of
lowered electricity rates, and an aggressive campaign by
Florida Power and Light to increase electrical consumption.
This was done by offering electric water heaters at bargain
prices. Thus Florida’s solar water heating was brought to
halt.
The United States is not the only country with a solar
water heating history. There are many other countries where
solar water heating was used in the past and has since
fallen out of use – but not all of them. In fact, currently
more than ten million Japanese households heat their water
using solar water heating systems. This is definite proof
that it is a workable technology.
Important Facts about Solar Hot Water Heating Systems
* Solar water heating can be used in any climate. Sound
unbelievable? Check it out on the U.S. Department of Energy
website. They say so as well.
* The fuel used to run a solar water heater is sunshine.
And, at the time of this writing, sunshine is free – no tax
has been added yet.
* A solar water heater can reduce your water heating bill
by 50%-80%. But with energy prices going up, the amount of
savings will soon be even higher.
* Aside from reducing your energy bill right now, a solar
water heating system will protect you from future energy
price increases. Your heating will no longer rely on fossil
fuels for electricity.
* When building a new home, or when refinancing, the
economic aspect of this becomes even more interesting.
You can, for instance, include the cost of a solar water
heater with a new thirty-year mortgage package. This would
usually amount to about $13.00 -$20.00 a month. Federal
income tax deductions for mortgage interest would reduce
the payment for the solar water heater by about $3.00
-$5.00 per month.
If your fuel savings with a solar water heating system is
$15.00 or more per month (which it likely will be) you will
have reduced your monthly heating bill right then and there.
* Solar water heating will significantly reduce your carbon
footprint, and reduce the demand for fossil fuels which
pollute the environment.
* Solar heaters can be installed in combination with backup
systems. In fact, you could install a solar water heater
next to your existing system and make it possible switch to
conventional water heating whenever necessary. This way you
are guaranteed always to have hot water.
-Types of Solar Hot Water Heating Systems
There are two types of solar water heating systems, active
solar water heating systems and passive solar water heating
systems. They both work on the same principles.
The only difference is that active systems have a pump or
other mechanical means of moving the water through the
solar heating systems, and passive systems rely on nature’s
principles: warm water rises to the top, and cold water
sinks to the bottom. With a passive solar water heating
system, the water storage tank must therefore always be
positioned above the solar water heater collector.
- Active Solar Hot Water Heating
There are two main designs of active water heating systems.
Which one is best for you depends on the climate you live
in.
There is what’s called an “indirect circulation system”
which uses a non-freezing heat-transfer fluid to transfer
heat from the collector to a heat exchanger (a device used
to transfer heat from the heat transfer fluid to the water
in your storage tank). This is good for colder climates.
There is also the direct circulation system, where water is
simply passed through solar heat collector and then routed
to the water storage tank for use. This system works fine
in milder climates.
- Passive Solar Hot Water Heating
Passive solar water heating systems are usually cheaper
than “active solar water heating systems,” as they do not
need controls or pumps to circulate the water.
But generally, they are not as effective as the active
systems. If you live in a warm climate, a passive water
heating system might be all you need. Passive water heating
systems are also known for being very reliable.
Essentially, solar water heating systems consist of a water
storage tank and its solar collectors. The solar collectors
are used to collect solar energy which heats water, and the
tanks store the heated water. That’s all there is to it.

Definition of Stem Cells and Benefits of Adult Stem Cell Research
Benefits of Our Own Adult Stem Cells
Everyone is aware of the controversy surrounding embryonic
stem cells. Stem cells are found in human embryos, but not
everyone is aware that stem cells are also found in adult
tissue. The most abundant supply of adult stem cells is
formed in the bone marrow.
Stem cells are “master” cells. In other words, they have
the ability to become any cell within the body. According
to the National Institute of Health, stem cells have the
remarkable potential to develop into many different cell
types in the body. Stem cells can theoretically divide
without limit to replenish other cells as long as a person
is alive. When the stem cell divides, each new cell has
the potential to remain in the bone marrow or become
another type of cell with a more specialized function, such
as: a eye cell, a muscle cell, a liver cell, a skin cell,
etc. Through a natural process, stem cells circulate to
areas of the body where they are needed and replace
dysfunctional cells. Adult stem cells also have the
ability to rebuild, renew and rejuvenate the body. Recent
scientific developments have discovered that stem cells
derived from the bone marrow travel throughout the body,
and act to support optimal organ and tissue function. The
circulation of millions of additional stem cells in the
bloodstream could be one of the safest and most efficient
methods for maintaining optimal health that science has yet
discovered. This recent advance in stem cell research was
listed as one the most significant health-related stories
in the past 25 years by CNN, second only to the complete
mapping of the human genome.
Our body requires vitamins, antioxidants and good food,
because they provide the nutrients for healthy tissue, but
they do not provide the building blocks to renew tissues,
bones, organs, or any part of the body. Traditional
nutritional supplements nourish existing cells; they do not
renew body tissue. As we get older, the number and quality
of stem cells traveling through our body gradually
declines. This decline makes us more susceptible to injury
and other health challenges as we age. A constant release
of our existing stem cells into the bloodstream can produce
incredible health benefits.
By supporting the body’s natural renewal system, we are
able to support the natural process of recovery from
exercise to build strength and stamina.
To summarize, there are no doubts regarding the value of
our own adult stem cells.

Homemade Wind Generator Plans
Save on Energy: Make a Wind Generator
I do not need to tell you that energy costs are currently
soaring since you are probably all too familiar with the
effect of rising fuel bills on your budget. It may not seem
like it now but time like these can actually be beneficial
over the long run since they force us to seriously consider
alternative when it comes to our energy need. One of these
alternatives would perhaps be to generate your own
electricity. How can you to do this? One of the best
answers to this question would be to build your own wind
generator!
Please bear with me for a second in case that last sentence
almost convinced you to just keep paying your high
electricity bills. It is not nearly as difficult to build
your own wind turbine. There are, furthermore, some very
real benefits to be gained from doing so. Let’s look at the
latter first:
* Cost: The first, and for many the most important, benefit
building your own wind turbine is obviously that it will
slash your energy expenditure. Putting up a simple system,
perhaps combining wind with solar energy, could possible
supply in all of your energy needs. That could amount to
hundreds of dollars of savings per month.
* Environmentally friendly: We are all aware of the fact
that long term dependence on fossil fuels is simply
unsustainable. Using a natural, freely available, resource
like the wind can help you to ‘do your bit’ to help the
environment.
* Profit: Believe it or not, but you can go beyond simply
generate power for your own needs to generating surplus
energy and selling it to the electricity networks. While
few of us have large enough properties to actually make a
living from doing this, most of use would find the extra
few dollars per month very welcome!
This is all well and good you may say, but I am not a
technical person and do not have the skills and know-how to
put up a highly complex and possibly very expensive system.
Good news on both counts! It is not expensive to build your
own wind turbine and you also do not need a great deal of
technical expertise. You can, in fact, use materials that
are freely available and relatively cheap.
I would like to strongly encourage you to seriously
investigate the possibility of switching at least part of
your energy consumption to homebuilt wind generator power.
If you do this you will find that you will reap the
benefits of just a little bit of study and some basic work
for years to come!

ACL Knee Injury and Surgery for ACL Injury Knee Pain
Knee Pain Relief: An ACL Injury & How Reconstructive Surgery Can Help Your Knee Problem
What is your ACL?
The acronym, ACL, stands for the Anterior Cruciate
Ligament. Along with your PCL, LCL, and MCL, the Anterior
Cruciate Ligament helps to provide stability to your knee.
Due to its attachment on the femur and tibia the ACL
resists anterior translation of the tibia, in relationship
to the femur. In other words, it prevents your lower leg
from sliding forward in relationship to your upper leg.
ACL Surgery
ACL surgery uses Autografts, (which is a tissue or organ
that is grafted from one tissue or organ in your body,and
subplants that same tissue somewhere else, in your body).
For example, ACL surgeries can use a patient’s own
hamstring or patellar tendon, in place of the torn ACL.
After having an ACL surgery, there is still a chance that a
person can reinjure their anterior cruciate ligament. If
this does occur, a person can undergo a second ACL
reconstruction. A bone graft may be needed, at this point,
because of holes in the bone. The new screws in the second
ACL reconstruction will need a firm hold. The bone graft
allows for these holes to be filled, so that in consecutive
ACL recontruction and the screws in this operation will
have a proper, well anchored fit.
What is an Allograft?
An allograft in this instance would be an ACL, or other
useful tendon taken from one member of the human species
and grafted to a genetically dissimilar person. In an
allograft, the anterior tibialis tendon, the Achilles
tendon, or the patellar tendon can be used from a cadaver.
When using an allograft, there is a possibility that the
graft will be rejected. This may lead to another surgery to
remove the graft and repeat the reconstruction process.
Recovery
The recovery period for this type of surgery will often
include physical therapy, and make use of a well designed
knee brace. Your physical therapist will work with you on
range of motion (ROM) exercises. ROM exercises are used to
regain the flexibility of the ligament. Moreover, ROM
exercises are used to help prevent scar tissue from
forming, and help maintain muscle tone. – In addition, the
use of a post operative knee brace can help provide support
to the knee while it is in this vulnerable position. Later
on, a functional acl knee brace can be used to help provide
meaningful support in activities of daily living. These
knee braces can help promote healing, and help to reduce
pain in your knee as well.
One of the benefits of a reconstructed ACL, is that there
is a high success rate. Studies have shown that if the ACL
retears, it will be due to a traumatic impact or severe
injury. This is not likely to happen, unless you
participte in contact sports.

Installation of Home Solar Power Systems
What Homeowners Need To Know About Getting Solar Panels For Their New Home
Installing a solar power for a new home requires plenty of
planning. If you don’t have a solid plan in place, then it
won’t work. The purpose of having solar power in a home is
to help homeowners save on their energy bills.
When everything gets configured with the new home, the
homeowner will determine how may solar panels they will
need. There are two ways that solar powered panels can be
selected: there are those that provide power to all of the
needs of the home; the other one connects to the existing
power grid.
The homeowner may or may not have to size up the power with
a separate system. If they plant to connect to the power
grid in their area, then sizing won’t be needed. Whatever
the homeowner’s budget is, use what you have and do the
installation.
The grid power is the supplement and starts where the solar
power system stops. The homeowner should check to make
sure that additional components can be installed later on
if they want it. Also, they should also see about getting
the grid tied into their area.
With the solar power system, there are several places where
it can be installed:
- Roof
- Ground area
- Posts
If it is to be installed on the roof, the homeowner needs
to make sure that the roof is strong enough to hold a solar
panel.
Solar panels carry a good bit of weight. Also, the roof
should face the sun for most of the day, if not all day.
The more sun exposure the roof gets, the more energy your
home will receive. Make sure that the roof is clear of any
obstacles, including trees or buildings.
There are different providers that make solar panels. The
homeowner can check online for different distributers that
specialize in solar panels. Or, they can visit a home
improvement store. Before a homeowner has settled on an
installer, they need to get at least three quotes before
they make a decision.
They should also make sure to check their references. The
last thing they need is someone that claims to be something
they’re not. If they’re not sure about who to contact,
one thing they can do is to see if any of their neighbors
have solar panels. Inquire with them to see who they used
to install theirs. Ask questions regarding the quality of
the installation and the service.
In addition to adding solar power to a home, solar power
can also be used for outside lighting and ponds or
fountains. The homeowner won’t have to concern themselves
with having wires strung all over the place.
Another incentive to having solar panels installed is that
homeowners can qualify for rebates for appliances that are
deemed energy efficient. They can check online to get more
information on this program and similar ones.
In the long run, homeowners may end up paying a lot of
money for their appliances, but in the long run, will
benefit from doing so for many years to come.
