RE: New Technology

2008-05-06 Thread Kunde, Brian
I agree that solar power is limited on the earth's surface. The only way
to get large amounts of energy from the sun is to go into outer space.
The problem then is how to capture the energy and transport it to the
surface?

Solar panels can be placed in areas that are unfavorable for growing
food, such as deserts.

The commodities market is very fickle. The raise in corn prices will
adjust in a few years as supply and demand is balanced out. I think the
ethanol gold rush has come and gone anyway. Currently, corn futures in
the US are high because of the wet spring has delayed planting. A bumper
crop of winter wheat has driven the price of wheat futures way down. So
farmers will plant more corn next year which will drive corn prices
down. It all works out.

I disagree with those who think ethanol is every bit as harmful to the
environment as petroleum based fuels.  The CO2 given off by bio-fuels
came from the air to begin with and when it is burned the CO2 is simply
returned to the air, so bio-fuels have no affect on the environment.
However, the CO2 given off by burning fossil fuels are taken from the
ground and adds to the CO2 already in the air and that is only a problem
if you believe the .01% increase in CO2 in our atmosphere is going to
destroy our planet. I think it is only going to make things grow better
which will increase corn yields and drive prices down. 

How does this topic relate to our jobs other than we are engineers and
scientists?  I recently read a news story about a guy who claims he can
burn seawater using RF and he believes this technology could be a
future fuel source. The man is a ham radio operator with no science or
engineering background, but after showing a video of his experiment he
is getting millions of dollars in research grant money to continue work.
I wish I could figure out how to get some of that money.

This is a Fun topic. A nice distraction from my boring life in the EMC
lab. Excuse me while I try to blow up a power supply with Surge.

 Keep in mind that all BIO-Fuels, corn, sugar cane, whatever, is just 
 solar energy stored in solid form, in this case, carbohydrates which 
 can be converted to alcohol or other hydrocarbons. Crops grow only for

 a few months out of the year, the rest of the time the land (solar 
 energy hitting the
 land) goes to waste. The land use would be better served to install 
 solar panels than crops where the sun's energy could be used year 
 round. The problem with solar panels (other than their inefficiencies 
 and expense) is how to store and transport the energy.

And that they take up a significant surface area to produce
significantly useful amounts of commercial energy.  Some of that land
would be taken out of agricultural use to support commercial solar
energy production.

Reports of food shortages due to crops being diverted into energy
production tend to make claims of conversion of agricultural lands into
solar energy production unfeasible.  Nationally, WalMart has reported
runs on rice, because of media driven concerns about shortages.  Third
world aid is also effected.  All of these shortages cause food prices to
rise above the rises they might otherwise see derived from crude oil
speculation.

Some recent reports also indicate that ethanol is every bit as harmful
to the environment as petroleum based fuels.

My direct report manager recently added in a relatively small, 14 kW
solar panel array onto his pool house.  This will pay for itself
eventually, in the form of utility savings, and might last long enough
to turn a small profit before its last gasp.  This form of solar seems a
more likely option for solar than removing land from agriculture.

Ultimately, all forms of matter are energy storage mechanisms.  Getting
the energy out is always an inefficient process, but some cost less than
others.

 Other than some new technology which hasn't been invested yet, I think

 the only solution is to go up (more solar power from the sun) or down 
 (geothermal heat energy from the earth's core).

We shouldn't place too much emphasis on any specific technology.  We
need a balanced portfolio.  But we also need bureaucratic, regulatory
and legislative barriers lifted to allow wider deployment of a broader
range of technologies.  Among the barriers are environmental regulations
and special interest groups that protest every possible effort to
resolve energy issues.

Wind is an excellent source of energy, which is also a solar energy
storage mechanism, if thought of in the broader sense, and doesn't
require direct impingement of solar radiation to function.

The energy you get from solar, whether bio-fuels or panels, are limited
by the amount of sunlight that is present per acre, which is not a lot,
comparatively speaking. So any solar energy method will only meet a
small fraction of the world's energy needs. 

Other than some new technology which hasn't been invested yet, I think
the only solution is to go up (more solar power from the sun) or down
(geothermal heat energy from the earth's core). 

Hydrogen is not truly an energy source but an energy storage method. You
cannot get any more energy out of hydrogen then what is put into making
it (generally from water). So hydrogen is not an energy source but
electrical energy stored in a physical form. Hydrogen stores a lot of
energy by volume so it does make a good fuel transport and is lighter
than batteries. Countries that have an abundant electrical energy (like
Greenland) can convert it into Hydrogen and transport it to other parts
of the world.

Re: New Technology

An interesting discussion. I'd like to inject a few 
points:

Prior to the discovery of petroleum oil the main 
source of oil for lamps was the rendered 
blubber of sperm whales.

Pollution from coal-fired locomotives destroyed 
streams next to railroads. This was the public 
transportation of the day.

Pollution from horses was a huge problem and 
health hazard in cities.

Each generation has it's challenges. Every time 
I hear someone say they would like to eliminate 
the use of oil I want to remind them that 
gasoline is just one of many products derived 
from a cracking tower. Most people would be 
shocked to know how many vital items are 
produced from oil.

Many alternative energy solutions bring their 
own new problems. Using corn to make ethanol 
for fuel is causing food supply and price issues. 
Windmills are noisy, and expensive to build and 
maintain. Electric and hybrid vehicles have 
issues related to the batteries and controls. 
Firefighters and other emergency workers are 
concerned about safety in accidents. The 
average mechanic is forbidden to work on them 
and the ones who have been specially qualified 
are in great demand.

Ken Javor has stated the real problem 
correctly. The Overlords want more control of 
the kind they had at the dawn of the industrial 
age and will try to get it through engineered 
crisis'. Many years ago I wrote an opinion piece 
(never published) on this subject titled 
Gunpowder and Gasoline, Portable Power to 
the People. My opinion has not changed.

Besides, as a motorcycle owner in the 
Northeast, Global Warming = more riding days.

Re: New Technology

2008-05-02 Thread Ted Eckert
Although it is a minor correction, let me state that soot from inefficient gas
lighting and coal burning was a major source of pollution in the early 20th
century.  In St. Louis, the Missouri Botanical Gardens bought a large piece of
property far from the city with the intention of moving their collection.  The
particulate pollution in the city was so bad that most of the plants at the
garden were in poor shape or dead.  Electric power replaced gas and coal
before the garden staff could move their collections.  The air quickly became
clearer and the Missouri Botanical Gardens has remained in its original
location.
 
The introduction of new technology in itself does pose environmental
questions, but the problems often stem from political issues, not technical
issues.  What would it take to build clean nuclear power plants?  There are
good designs available, but there are political problems getting them built
and tested.  Hydroelectric power looks good, but dam placement has political
implications in addition to the environmental implications.
 
As engineers, we can continue to work to make existing technology more
efficient and environmentally friendlier without raising the cost.  It needs
to be done with an economy of incentives.  The improvements must be
economically and politically acceptable to the masses.

Re: New Technology

2008-05-02 Thread Ken Javor
Precisely my point. The Ubermensch morphs into Overlord. Electricity is
rationed, we are told where to live and in what size domicile, what we can
drive if we are allowed private autos, and the list would not doubt go on
forever.  Many of these types of controls were indeed in place during WWII,
when both sides were in a struggle for their very continued existence.

It is not coincidence that the excuse for imposing these controls during
nominal peace time is a crisis advertised to once again doom civilization -
global warming.  The would-be Overlords, who are in reality Untermensch,
fully recognize that a crisis of global proportions is necessary to impose
the controls they wish to exert.

 A more basic question. Would Edison? slight bulb have ever illuminated
 the night if an environmental impact statement had predicted the
 electrical power infrastructure necessary to support it, and the
 resultant ?man-made global warming??
 
 When measured against the emissions of the candles, oil lanterns, torches,
 fire places, camp fires, signal fires etc.
 Probably.
 
 The major pollution factor in the large cities in the early 1900s was horse
 exhaust.
 With which exhaust would you rather deal horse exhaust or petrol fumes?
 
 It is not the technology that is the problem, it is the abuse of it.
 We could turn off at least 60 of the lights we use at night to little
 effect
 If we had effective mass transit the automobile exhaust could be greatly
 reduced.
 If we all lived closer to our jobs the same would be true.
 If we didn't insist on an automobile that weighed as much as the Queen Mary
 and went from 0 - Mach 1.5 in 13 nanoseconds, there would be a lot less
 also.
 If we lived in houses that were sized properly . . ..
 
 Until we make some hard choices about our comfort and preferences, things
 will continue to deteriorate.
 New technologies will only transfer the pain to another venue and/or time.

And the same crowd that is screaming man made global warming was
screaming man made ice age 35 years ago.  Disaster de jour for exactly
