Electrical meters seem to be in the news this week, one is
in the 'top story' section related to conservation, others
are in the business section. Thinking about the question of
changing frequencies on transmission lines, and having seen
more about small motors (stepper motors, with many small
magnets that enable certain precision rotational movements),
it seems that a change in frequency would be 'out of step'
with much of the existing hardware which relies upon certain
specific designs to work with alternating current, as the
quote from Networks of Power indicated having to replace a
lot of equipment when moving from 40hz to 50hz, though in
addition that equipment may not work even if power is being
supplied to it because it is specific to frequency, or so
it seems to be this way. If one has a chance, take a look
at the 'battery photograph' in the power section, it is of
note that a company uses styrofoam instead of a battery cell
inside the metal casing. Another thought on having a PDA
that has now died when sent a replacement for battery issues
is that it is wondered why 'circuits' require batteries to
always run power through them if this runs batteries down
over a period of time. A common saying is to take out the
batteries if not using something for a period of time, to
save the equipment and the batteries. Yet, this is a design
issue which could decouple the batteries to save the wasted
energy, as the shelf-life of a battery far exceeds what is
the result of leaving them idle in an electronic circuit.
This seems to be a result of bad design, not bad batteries,
and a standard for conserving the wasted resource could be
figured out and implemented, it is believed, to save a lot
of wasted resources, power, and electronics devices through
some commons sense decisions. Of interest, also, in the
use of electronics language in politics has been that of
'flip-flop' but also 'fuzzy math' as a form of insult. In
reading about wireless sensor networks it would seem that
without flip-flops (other reading) computers would not now
exist as they do, and without fuzzy-logic, and fuzzy-math,
it is assumed, artificial intelligence and other advances
(in thinking, no less) would be available today. So it is
wondered if political talk is actually a masked ludditism,
a fear of the unknown and a demeaning of new core concepts
that change the nature and understanding of reality, such
as allowing for paradox and for changes in 'time' during
a period of decision making, instead of a static vantage
of events, as if the individual human brain were a limit
upon what is possible in a world of 6 billion of these in
various states of consideration, questioning being alive.

100,000 kWh/y; however, through CONSERVATION and EFFICIENCY this has
been effectively reduced to 75,000 kWh/y. Greenhouse concerns and the
dwindling supplies of Oil and Natural Gas have effectively eliminated
these fuels from use. Coal is still abundant and being used. In order
to meet the energy demands, a new mix of resources and technologies are

'There are now five simulator packages available. The newest, is an
international version of the Energy Project 2100 project described
below. There is also a new U.S. Energy 2004, which is an updated and
simplified version of the 2001 simulator. Each simulator puts the
student in charge of some aspects of national energy management. In
most cases, the primary control is over the actual resources used to
provide energy. The 2001 U.S. simulator is more detailed but also
requires more time to complete than the new 2004 version. The Energy
Project 2100 package is very detailed in looking moving the energy
resources from the fossil fuels to renewable energies, but because of
the intrinsic 5-year time increments can be completed in a reasonably
short time. The World simulator can be used for either detailed study
of the international picture or in an automated mode to quickly 'see'

on that project. This new simulator is more compact and plays more
quickly than the two simulators below. It deals more specifically with
the task of replacing oil and natural gas with renewable resources by
having the student decide how many wind generators, photo-voltaic
panels, new dams, new nuclear plants, new geothermal plants, acres of
farmland to dedicate to fuel crops, etc. The cost of all of this is a
major factor and includes both debt service and the replacement costs
of units that wear out. Other factors are considered such as increased
efficiencies and possible conservation steps as well as the need to
store some of the solar and wind energy. By using five-year steps and
the ability to retain most settings, the exercise can be completed

High-performance, Single-crystal Plastic Transistors Reveal Hidden
Printing circuits on sheets of plastic may offer a low-cost technique
manufacturing thin-film transistors for flexible displays, but
the performance of such devices will require a detailed, fundamental
understanding of how charge flows through organic semiconductors.
'The fabrication technique -- developed by researchers from Illinois,
Rutgers University and Bell Laboratories, Lucent Technologies -- not
only provides a way to study the physics at the heart of charge
transport in these unusual materials, it also has resulted in the
highest mobility recorded in an organic semiconductor. The use of
transistor stamps promises to open up the field of basic study of
organic semiconductors by allowing devices to be fabricated from
pristine organic crystal samples that remain untouched by conventional
chemical or mechanical processing.' ... 'As charges flow through
conventional thin-film polycrystalline materials, they encounter
boundaries between the crystals that disrupt their movement. By
studying single crystals, Rogers and his colleagues can eliminate the
effects of these grain boundaries and examine the intrinsic transport
properties of the crystalline material itself.' ... 'Because the bond
between stamp and crystal is not permanent, the researchers also can
remove the crystal, rotate it, and reattach it to the substrate.
Repositioning the crystal allows the scientists to explore the
dependence of the mobility on the orientation of the transistor channel
relative to the crystal axes.'

fabrication of building components; material cost-calculation (as
opposed to mere estimation); construction simulation and
construction-site logistics simulation; electronic radio-frequency

their technology decisions down to making the right CAD or BIM software
