ONE THOUSAND DAYS
Curtis A. Johnson, P. E.
President William Clinton - in his State of the Union Address, asserted that we
have about 1,000 days remaining in this century to accomplish the goals
outlined in his challenge to all of us.
Action -- rather than a Constitutional Amendment -- is required of all of us.
Together. And, in spite of Andy Rooney's mild criticism of the redundancy of
those, and other words in the speech, the substance and the clarity of the
proposals made came through loud and clear.
Education -- the central component of the means to achieve the goals that the
president outlined -- applied to each and every age group -- must consist of
truth -- scientifically established facts -- as best they can be determined --
both experientially and theoretically.
The proliferation of junk science, largely purchased and promoted by those
hoping to gain financially by such distortion of truth needs to be sharply
reduced.
1. The attempts to hide the very serious health hazards by non-scientific
information about tobacco, paid for by the tobacco companies, and supported by
a congress -- effectively bribed by those same companies -- to the detriment of
the voters and their children -- demonstrates how truth can be and is
manipulated.
2. The intentional withholding of the results of federally sponsored research
reports, such as the details of the successes established by the Oak Ridge
National Laboratory in the ACES** project illustrates another way in which
vital information does not become common knowledge and does not reach the
people who could use it as soon as it was proven to be fact.

Winter, 96-97, p. 1-4.
**See the January 1997 Report -- Ice-Maker Heat Pump, a new tool for energy
conservation, by H. C. Fischer, Energy Division, Oak Ridge National Laboratory,
Operated by the Union Carbide Corporation, Nuclear Division, Oak Ridge,
Tennessee.
The Annual Cycle Energy System Report, has as its introductory summarization,
the following statement:
The high energy efficiency of the ice-maker heat pump makes it an attractive
source of heating and cooling for buildings at current electric rates. When
combined with heating storage and cooling storage, which make it possible to
take advantage of time-of-day interruptible rates, no system on the current
market can beat it. An examination of the resource energy requirements of
several systems shows that the Annual Cycle Energy System (ACES), which uses
the ice made during the heating season to handle the cooling load in the
summer, has the lowest resource requirement.
The ACES demonstration building, near Oak Ridge, and Knoxville, Tennessee,
illustrated that the use of the latent heat of water provides the means for
storage of excess summertime heat in an underground, insulated, storage tank.
This warmed water, in turn, was cooled by the ice-maker refrigerator system in
the winter just following, and used to heat the house.
Using the long established principle of the heat pump, an ice-maker
refrigerator compressor extracts the heat from the warmed water, first cooling
it down to freezing temperature, then freezing it. As the volume of fluid water
is converted into ice, it is stored in the well -insulated underground tank, is
available for summertime air conditioning without operating the refrigerator
compressor at all during the following summer.
While this appears to violate the basic physical concept that the Thermal
Efficiency (TE) of any system cannot exceed the value of 100% -- (the first law
of Thermodynamics) -- the fact remains that the ice-making refrigerator has
been used for more than 75 years -- to extract heat from water with what seems
to be 200% efficiency. Engineers have simply labeled it differently, calling
that capability of the machine its coefficient of performance (COP). The
economic fact is that the ice-maker requires only one (1) kilowatt hour of
electrical current supplied to the compressor, to extract (2) kilowatt hours
worth of heat from the water in the conversion of liquid water to ice.
The heat energy equivalent of one (1) kilowatt hour is 3413 British Thermal
Units (BTUs). The extraction of 6,426 BTUs of heat from the liquid water is
accomplished by only one (1) kilowatt hour of electrical energy that powers the
motor driving the compressor. Furthermore, when used as a heating device for
home heating, a total of 10,239 BTUs is removed from water in the process of
ice formation, at the expenditure of only one (1) kilowatt of electrical
energy. Therefore, a COP of 3 is factual -- when the ice-maker is used as a
heating device. (When you feel the hot condenser coils of the back side of
household refrigerators or freezers, your sense of touch verifies this is
happening -- and is the source of heat utilized in heating the house with the
ice-maker refrigerator of the ACES equipment.)
The overall result of the ACES concept -- on the annual basis -- is that the
stored block of ice accumulated during the winter in the house heating phase of
its operation, provides the cooling medium for the summer-time air conditioning
of the house. Circulation of ice-water around the huge block of ice, and
pumping it through finned-tube heat exchangers located at the picture-molding
location in the rooms to be cooled, replaces our window type air conditioners
(usually noisy ones at that) with the cooling effect of ice-water flowing
through the pipes. This also eliminates the need for any (often unsightly)
solar collectors mounted on the roof of the house, since the un-avoidable
heating of the building accomplished by ventilation of the house, leakage of
heat into the house through windows and doors, the body heat of people,
cooking, dishwashing, lighting and all other sources of heat within the
building, as well as incomplete insulation of the walls, windows and roof --
provide the interior heat which is extracted by the circulation of the cooling
water. When this unwanted summertime heat is transported by the warmed
ice-water back to the underground storage tank, it melts some more of the ice,
and thus stores the heat that can be pumped out of the warmed water, frozen and
used during the winter heating season.
The beautiful result of this is that since the refrigerator compressor is not
needed during the summer, the air conditioning cost for the summer is virtually
eliminated. The economic result is the production of an Annual Coefficient of
Performance (ACOP) of 3 + 2 + = 5. This is the same as 500%-- thermally
considered impossible, but economically factual, as demonstrated by the test
houses near Oak Ridge Tennessee. It was my privilege to visit this
demonstration house in the summer of 1978.
The enclosed tabulation of the Heat Storage Potential (latent heat of water)
that I prepared in 1975 provides the mathematical proof of the tremendous
capability of the systems using the heat of fusion of Water-Ice incorporated in
the ACES concept.*
This energy storage capability provides the means for storing summer-time heat
for winter-time use, and storing the ice so formed for cooling in the summer.
When this Annual Coefficient of Performance provides the established potential
of making 1 kilowatt hour of electrical energy do the work of 5 kilowatt hours
of heating and cooling, this simply means that the energy cost for the year can
be divided by 5.
When the known fact that it takes approximately 3 kilowatt hours of fossil fuel
or nuclear fuel energy to generate, transform, and transport 1 kilowatt hour of
electric energy to the point of use at the refrigerator compressor, it is quite
obvious that 3 X 5 = 15 !! Fifteen kilowatt hours worth of fossil or nuclear
fuel must be provided to accomplish the same job on the annual cycle of heating
and cooling. It then becomes obvious that when wind energy is available to
replace the fossil and nuclear fuels, the use of this continually renewable
resource is the ultimate answer to many of our ecological problems as well.
It is recognized, of course, that the materials of construction and the energy
required to manufacture the windmills must be considered as a part of the cost
of producing the output, whether it is electricity, or hydrogen or the
prime-mover energy to drive a refrigerator compressor directly. But, the well
proven longevity of refrigerator compressors, the safety of underground
pipelines for transporting gaseous substances or the physical durability of
managing radioactive materials all combine to make the windmill the economical
choice.
Quoting again from Windpower Monthly, the Jan. 1997 issue, page 6: If the mind
power now devoted to fossil fuel and nuclear energy exploitation were put to
devising a long-term framework for sustainable use of energy, the job is well
within the bounds of man's intelligence.
*Tabulation of calculated value of the Heat of Fusion of Water-Ice, which
provides the storage potential for cubes of ice of various sizes, prepared by
Curtis A. Johnson, at the University of Massachusetts in 1975.
A variety of references have quoted the fact that the annual energy available
from wind alone can readily be obtained from the mid-western states -- from
North Dakota on down to Texas -- sufficient to completely replace all of the
annual energy requirements of the United States currently supplied by the
combined oil, coal, nuclear and biological source materials.
The intermittent nature of wind energy has often been the stumbling block in
the technical development process -- where the attention has been directed
largely toward the conversion of wind energy into electrical power, for
harnessing it directly to the grid systems with specific Hertz (60 or 50 cycles
per second) alternating current.
When we are willing to abandon complete tie-in to the grid system, it opens up
new concepts of energy conversion, distribution, storage and the related
ecological advantages and efficiencies.
THE ROUTE?
1. Concentrate upon initial generation of direct current electricity.
2. With permanent magnet rotating elements, the DC power need not pass from a
rotating commutator to stationary brushes. Even though the initial output
developed is alternating current, integral rectifiers convert AC to DC current,
with a pulsating, but uni-directional flow of electricity.
3. By means of the electrolysis process, the direct current can disassociate
water molecules (H2O) into hydrogen (H2) and oxygen(O2
). Both of these molecules as gaseous products are storable, wither under low
pressure, high pressure or, with the hydrogen, into metallic hydrides, as the
ultimate use may require.*
* Documentation of this is detailed in Solar Hydrogen -- Moving Beyond Fossil
Fuels, by Joan M. Ogden and Robert H. Williams, World Resources Institute.
Princeton University, 1989.
4. Pipeline distribution of hydrogen fuel has been demonstrated to be a
lower-cost energy transmission system than the electrical grid system. This
would not immediately eliminate the grid system, of course. Pipeline
transmission of hydrogen to major electrical generation locations would need to
continue -- but with the hydrogen powering the prime movers that power the AC
generators. Thus, much of the smog and CO2
can be quickly eliminated at that point source of pollution, since combustion
of hydrogen has as its primary waste product -- water.
5. Hybrid systems, in which windmills and photovoltaic cell systems, both
producing direct current, when combined to have an output product of hydrogen
gas, foster almost round the clock* energy harvests. Various combinations of
electrolysis systems, capable of operating at several voltages and amperages,
will allow for various wind speeds without attempts to keep the rotor shaft RPM
at some precise level. Therefore, from the lower wind speed that produces
significant amounts of energy, to the highest velocity that can be designed
for, all of the available wind energy may be harvested. Since the output
wattage itself provides the brakes to manage the rotor velocity, no energy
wasting friction brakes need to be applied to control the rotor speed. The
armature of such a generator, since it consists of powerful permanent magnets,
is the moving part of the generator. The stationary coils (that are connected
internally to rectifiers which change the induced current in the coils to
direct current) allows for simple external connections to the electrolysis
systems. Voltage or amperage controlled switching devices can then connect the
output energy to whichever equipment is suited for the available power.
6. The above combination of devices then combine to be, in effect, a
dynamometer, since voltmeters and ammeters can measure instantaneous digital
readings of the output. When volts x amperes = VA = watts, very accurate output
energy can be recorded. Since the electrolysis system, through its switching
arrangement, can vary the electrical loading, the reduction in the rotor rpm
can be controlled, electronically, to absorb the maximum power output of the
windmill. When the wind velocity decreases, the electronic controls can change
the electrical loading to conform to the instantaneous maximum power that may
be produced at the lowered rpm.

Turbine) I Windpower Monthly Magazine, June 1995, Vol. II, No. 6.
7. Initial storage of hydrogen gas produced may be in floating, inverted tanks,
comparable to the temporary natural gas storage units associated with pipe line
supplies being distributed to branch lines to its various users. To the extent
of available markets for oxygen gas, similar temporary storage may contain as
much of the O2
as may be profitably sold, with the balance simply released into the
atmosphere. Pressure gauges and pressure switches, controlling compressor pumps
for delivery of hydrogen to high pressure storage cylinders, or to intermediate
pressure gas line transportation systems, all may be off-the-shelf, standard,
available components. With the pumping energy derived from the hydrogen being
produced, from either the wind or PV source, no fossil fuel is needed for the
compression of the gas for transport.
8. Pipeline delivery of the hydrogen gas, via systems presently available for
natural gas transportation, would require relatively little modification to
handle the hydrogen. Consequently, adding hydrogen to the mixture will probably
be an interim transport technique, until available hydrogen production reaches
rates sufficient to warrant distribution in the pure hydrogen form.
9. Present electric (60 Hertz) generators, equipped with natural gas fired
boilers, with probably slight modification, could use the hydrogen enriched
natural gas, until the distribution lines are converted to hydrogen only
delivery.
10. Fortunately for both human kind, and all other forms of animal and plant
life on planet Earth, as progressively more hydrogen gas replaces all fossil
and nuclear fuels, the liberation of carbon dioxide from the combustion process
declines.
With the greenhouse effect diminishing, the climactic cycles can begin to
return to normal. With the elimination of the reliance upon nuclear energy, the
hazards of radioactive substances may make possible the goals of peaceful
relations among the diverse populations of the earth. The sources of necessary
energy for whatever purpose needed can be wherever there is wind or solar
energy available, and the have-not nations -- with widely scattered windmills
freeing them from the domination of the fossil or nuclear fuel magnates-- can
release them to rely upon themselves with energy itself replacing the need for
foreign currency, as expended normally for fuels of any kind.
11. While the changeover to a hydrogen economy cannot be an instantaneous one,
a sustainable future for life upon earth requires that all nations, all
industries, all educational bodies from kindergarten on through the advanced
degrees concentrate upon spreading the knowledge that it can indeed be done,
and work together to help make it happen -- as indeed, it must, if humanity is
to survive.
12. Quoting from The Windicator, page 50 of the January 1997 Windpower Monthly,
the current total of wind turbine -- wind power capacity stands at 5,839
megawatts (5,839,000 kilowatts). The U.S.A. portion of that is only 1,660
megawatts or 28.43% decline from the 47.45% portion that existed just one year
ago.
13. This drastic reduction in the share of the development and production and
use of windpower in the United States should be warning sufficient to both
government and industry. Falling way behind in this manner can only mean
losses: (A) industrial decline -- of peacetime production capacity; (B) decline
of job opportunities for people -- as work prospects are destroyed for very
capable individuals, dumped out of companies that have merged; (C) unadmitted
failure to come to grips with the environmental damage resulting from the
combustion products of fossil fuels; (D) the inability recognized world around
that technology has come up with no safe methods of assuring our own or future
generations that radio-active wastes can be stored, or that we can educate
future generations sufficiently to keep them from releasing those wastes into
soil, water or atmosphere.
14. If government and industry awakens in time, and recognizes that enlightened
self interest and the inevitable popular pressure that can develop with
widespread education of the foregoing possibilities, perhaps the greenhouse
effect may be brought under control.
15. Consequently, the job is well within the bounds of man's intelligence -- to
get the U.S. industry going:
A. With all deliberate speed, to become the world's No. 1 manufacturer,
distributor and installer of windmills of all sizes.
B. To adapt the ice-maker refrigerator compressor industries into the No. 1.
manufacturer, distributor and installer of these refrigerators, reverting back
to the use of ammonia gas if necessary, if the replacements for freon 11 or
freon 22 are not proven desirable.
C. Adapt the compressors to be adaptable to various prime movers -- electric
motors, direct drive from windmills, or driven by internal combustion engines
using hydrogen fuel. Adapt these engines for salvaging the exhaust gases --
incorporating them into the heating of tanks of water for domestic use -- with
these insulated tanks inserted into slightly cooler tanks that provide the hot
water for baseboard circulation in the building for space heating. The usual
thermal efficiency of gasoline internal combustion engines is 25% (TE), rarely
over 30%; and of diesel engines, in the range of 35%. The balance of the energy
supplied to such engines is wasted as heat released to the cooling water, and
lost, at the radiator -- plus the energy released at the exhaust system. With a
hydrogen fueled internal combustion engine adapted to the ACES system, the
radiator heat can be salvaged by incorporating its heat into the hot water
heating system for space heating of the house. The exhaust gases, since they
contain no CO2
, and primarily water vapor, can also be added to the hot water heating system
for space heating. Therefore, the overall thermal efficiency may reach into the
vicinity of 90% ± for the hydrogen powered prime mover of the ice-maker
refrigerator.
D. Design the windmill supporting structure for attachment of photovoltaic
cells. While the cost of electricity developed by PV cells is currently in the
range of five times as much as the cost of electricity produced by windmills
(in the range of $0.04 to $0.06 per kilowatt hour) the provision for their
attachment to the windmills should be made so that if/when the PV cells become
economically feasible, they may readily be added to the combined equipment,
wind and Solar Hybrid as previously described.
E. Develop the hydrolysis systems that can be appropriately sized to absorb the
Direct Current energy from either the wind or PV cell sources in all of the
practicable size ranges for the wind mills being built.
F. Associated with the above, manufacture and install the storage tanks, the
compressed hydrogen systems, the metallic hydride systems, and the pipeline
distribution systems, to prepare for the utilization of and storage of the
excess hydrogen produced during the various periods when wind power is
available, but energy use (night, or weekend) is minimal.
G. Also, develop the many presently dry wells of the petroleum fields, for
pressurizing hydrogen into them for long-term storage.
H. Adapt the present natural gas pipe line systems for handling of hydrogen --
directly to the electric power plants. As the proportion of hydrogen increases,
the CO2 output can progressively be lowered, and ultimately, to zero emission.
I. Accelerate government and industrial funding of additional research and
development of some of the more recent concepts relating to the harnessing of
wind power.* One such turbine is claimed by New Zealand researchers to generate
electricity at half the cost of conventional wind technologies, by means of a
diffuser-augmented wind turbine (DAWT) -- initially developed by the Grumman
Aerospace company in the 1970s, as part of a US Department of Energy funded
project. The advanced Windpower Ltd. (AWL) recognizes that its claims are
rather radical, but is confident that the demonstration machine will live up to
its billing.
J. Follow through with research on our own suggested in the December 1996
Windpower Magazine** relative to Desert Downdrafts -- if water is sprayed into
the top of a hollow cylindrical structure it will tend to evaporate
immediately, thus cooling the surrounding air and increasing its specific
gravity. That will cause the air to fall in the chimney, setting up a
considerable downdraft. If turbo-generators are placed at openings near the
bottom of the structure, that downdraft will activate them to produce
electricity. If such a concept is indeed a realistic one, the various desert
locations through out the world could become immense resources -- sources of
tremendous amounts of renewable energy, where it would seem that few if any of
the ecological disadvantages would apply -- bird populations, desecration of
beautiful scenic areas, costs of land involved, etc., that are frequently used
as excuses for preventing the installation of windmills.
*Windpower Magazine, December, 1996, page 27.
** Windpower Magazine, December, 1996, page 16.
K. When, and as, the hydrogen production from such potential renewable
resources becomes commonplace, the automotive industry should be ready to
provide electrically operated vehicles in quantity, at the earliest possible
moment. With the electricity provided by generators powered by hydrogen,
street-side convenience outlets can become as commonplace as parking meters.
Then, alternating current would be available for rapid recharging of batteries
at the deposit of a coin or credit card. Because renewable energy would be
supplying such battery chargers, virtually every parking meter could become a
source for filler-up energy with no qualms about pollution of the atmosphere.
L. As new designs of batteries of the lead-acid type, or the nickel-cadmium, or
the lithium, etc., are developed, the above technique of providing
parking-meter type filling stations supplied by renewable fuels, may be
appropriate for short-run, around town usage. Then other combinations may be
produced, such as the fuel-cell type, which can convert hydrogen fuel carried
in the vehicle to direct current for instantaneous use to drive the motors at
each wheel, or the hydrogen powered small internal combustion engines fitted
with a DC generator to recharge batteries that have been discharged when
exceeding their stored capacity. With these, the final few miles to the next
recharge station, can be made without being stalled on the road waiting for
some help to arrive.
M. The filling stations (as we think of them now) would become the providers of
replacement tanks of hydrogen gas, or of metallic hydride containers, as well
as the fast, high amperage recharge station, to supplement the parking meter
type of fuel supply.
N. As pure hydrogen gas becomes a widely distributed fuel, replacing the
natural gas in city and urban locations, the hydrogen then can be utilized in
the several ways, such as may be found to be most economic for the given
situation. Direct combustion in gas fired hot water or hot air space heating
systems, may require only changing of jets and making a few adjustments
appropriate for the new fuel. Or, internal combustion engines, now having only
water as the product of combustion, can be highly efficient units -- salvaging
the radiator heat and the exhaust heat as well, such that conceivably an
overall 90%± thermal efficiency (TE) may be attained. Or, with the
internal combustion engine hydrogen fueled, it may be the prime mover for a
complete ACES system, as described above. The completely self-contained ACES
system for either individual homes (for new construction), would therefore have
no need to be connected to the grid systems for source of electricity, since
the hydrogen fueled internal combustion engine could also power an AC generator
as needed. Retrofitting old homes by means of excavating for installation of
the insulated ice and hot water storage tanks may well provide jobs for many in
the construction industry. Similarly, with all other types of buildings --
schools, churches, manufacturing buildings and governmental structures, vast
new opportunities for productive work would become available.
O. All of the above will produce the need for large numbers of skilled workers
to complete the changeover to the new way of life. New small enterprises will
spring up, in producing, distributing, servicing and educating the public in
how best to choose or manage the systems. These, in turn, will generate an
earlier balanced labor market, in which there are as many unfilled openings as
there are unemployed seeking work. An economy with an expected steady 10%
inflation rate and a 1% unemployment level would be a prosperous economy,
automatically eliminating most welfare as we know it and alleviating poverty,
homelessness, drug addiction and crime.
P. In summary, the combination of the greenhouse effect upon our planet Earth's
atmosphere, the problems of the ozone holes developing over both the Arctic and
Antarctic regions of the globe, the acid rain with its damaging effect upon
many of our forests, the depletion of the several fossil fuels, (coal, oil and
gas supplies; and the rather complete ignorance of all of our scientists
concerning the safe disposal of radioactive wastes of our nuclear power
systems, to say nothing of the military wastes, or the Three Mile Island
nuclear power plants -- or the far shorter actual life of many of the nuclear
power plants-- all of these must drive us to begin at the earliest possible
date to reverse the damages of all of them. Few people can supply adequate
arguments for continuing in such inevitable destruction of our ecological
system.
Q. I submit that there are relatively few of the concepts contained in this
proposal to embark upon the hydrogen fuel era -- beginning at the earliest
possible moment -- that can be labeled as impossible, or uneconomic -- in the
long view. We are presently allowing European and Chinese production of
windmills to out-produce and out-utilize the renewable energy supply. Since we
are not likely to be able to build a fence around the sun, or determine where
the wind will blow, it is high time that we cooperate with nature in every
possible way.
Energy, in the form of how many cubic feet of hydrogen gas, at a standardized
pressure level, will become the monetary unit of the future. As the hydrogen is
produced, it should have a fixed value as delivered into a pipeline system for
distribution, no matter how small or large the delivery rate may be. Likewise,
when that supplier has no available wind, the repurchase of the hydrogen gas
should be available to him at some small fixed percentage above the cost he
received when selling it.
A tax deduction type of subsidy of about 30% of the new investment that
individuals or companies may make that contributes to the development of wind,
solar, hydrogen production equipment, hydrogen using facilities, should
demonstrate governmental approval of such steps toward building a sustainable
environment. This subsidy (tax deduction) should only be allowed upon the proof
of the actual construction and use of the equipment claimed as a deduction.
May the new hydrogen era begin now!
