Keeping Fossils
Underground
I develop technologies
that keep fossil carbon from changing the atmosphere and oceans. More than
thirty years ago I replaced the oil fired furnace that came with the house and
installed a wood burning parlor stove. In 1975, burning three tanks (more than
three tons) of fuel oil for heat was our home’s largest fossil greenhouse gas
contribution. To help the wood stove to keep us comfortable, we insulated the
house and upgraded the windows. We live on a hill where the wind often blows
hard and, in addition to eliminating drafts, these conservation
measures reduce how much wood and ash we have to handle. Years later in its
place we installed a wood burning cook stove that was much fancier and not only
does it heat our home, it enables us to prepare most of our meals, make maple
syrup, bake, and preserve food.

We burn about six cords,
nine tons when dry, of wood during a heating season. I glean about a third from
our eight acres and procure the rest from neighbors. But the electricity and
heat for water still add to our fossil carbon footprint.
Four years ago, the last
time we filled the 275 gallon fuel oil tank, I decided to phase it out. Now, on
a day we want hot water, we turn the system on for eight minutes that burns 12
ounces of oil (making 2.4 pounds of carbon dioxide). This warms enough water
for two showers, a load of dishes and hamper of clothes along with ever cooler
water for washing and cleaning up. When it’s very cold and we’ll be away for
more than a day, we use a separate loop off this system to keep the core of the
house above 50F that prevents the pipes and inside plants from freezing. The
oil tank is now almost empty and I've plumbed in an old electric hot water
heater to cover us when the oil runs out. Higher utility bills will become
an incentive to hurry and install a solar hot water system.
It's taken about two
centuries (probably by fewer than one billion people) to transfer
around half the readily available buried carbon into the air. That amount of
carbon dioxide is now changing the climate and acidifying the oceans. Coal, oil
and gas are becoming ever more difficult to find and extract and we don’t have
millions of years for geology to replenish these valuable fuels. Now more than
seven billion people want the lifestyles they see in media. That second half of
fossil fuels will dwindle rapidly and we all need new energy resources. And we
cannot afford inefficient remote power plants and the solar panels available
today. It's a waste of time to point fingers at big energy companies that bring
us the fossil energy we so much enjoy using. It's up to us to create better
solar tools.
For over 40 years I've worked
with the most powerful type of solar collector. These point-focus tools some
call solar dishes point directly at the sun and readily deliver more than
75% of sunlight for a variety of uses. A new design that my brother, Bob, and I
have been developing is easy to make and install using only hand tools and no
welding. Other types, including the more than 40 solar collectors we developed
and installed decades ago, required expensive manufacturing processes. And
it would take years of operation for them to pay for the cranes
needed first to put them up and again each time the primary drive or bearings
have to be replaced.

The solar collector
shown above generated 45 kilowatts of electricity, enough power and heat for 45
homes, was also my doctoral thesis. With storage, the new design, but
a size that has less than one tenth of the area of mirrors
above, should enable a rural family to live comfortably in northern climates.
Without subsidies, they should return their cost through the value of energy
they deliver in fewer than seven years, or even less if you are able to utilize
all the energy they could deliver during the summer. When many are happy with
how well their own systems operate, we hope that add-on modules for making
power, air conditioning and many more powerful applications will
become available.
During 2014 I will
report on progress developing this solar technology. I will also relate our
daily routines that support living well: gathering wood, making maple syrup,
gardening, putting away food and raising animals in ways that enhance the only
environment we share with all other species.
If any of the above prompts questions, requires clarification or
opens other topics, please let me know.
