"As it struggled, A123 showered Democrats with donations, hired pricey

That's tells us absolutely nothing new about how Federal grant money is acquired. Both Republican and Democrat politicians were pushing for that company. So your post is just another lie.

Bad, bad logic.

When government collects taxes, and then spends close to 40% of GDP,

everyone has an incentive to go to Washington and try to get as much

of "their" money back as they can. It's just one big pot of money, so

any concept of efficiency is lost. Lobbying and corruption happen

because they work.

As Willie Sutton said about why he robbed banks, "because that's where

the money is."

Apparently your reading comprehension is gone too. Ripping off government is the American way.

President Obama calls it "getting your fair share."

Inherently, the bigger it gets, the more people are tempted.
Eventually, they'll have no choice. When the government takes so much
that you can barely get by, they own you. Own you. Obama's put
record numbers of people in that position. Ironic, isn't it?

The Democrats, in the 1960's, discovered that that could use
government money to create an underclass that would reliably vote for
them. I love Caesar Chavez' summary of the situation. He told poor
farmworkers not to use birth control because it "reduces the numerical
power of the poor."

The "What's Wrong with Kansas?" perplexity of the leftists stems from
the fact that some people still have principles. Leftists are
dumbfounded by principles.

And more efficient. The cylinder essentially take a sheet of expensive
material and wraps 3/4 of it away where the sun don't shine.

Solyndra claimed that, on snowy days, light reflected by the snow
below the cells lit up the back side and increased output.

I've heard it said that Obama's not picking winners and losers, he
just picks losers.

He's a community activist and a lawyer. How would he know that

They weren't half the price at the time and the cylindrical panels were a
brilliant solution to the sun tracking problem without moving parts and
much more complicated installation.

I can't believe an engineer wrote the above. You are an engineer, right?
Click to expand...
Obviously not.




There's a good reason why serious installations use sun tracking,

Sure, but cylindrical cells don't do it.


it's called MUCH more energy harvesting.

Nope! *EXACTLY* the same energy falls on the cells per m^2.
Click to expand...
The cylinders intercept about half of it, while using four times the
expensive conversion material. And thinfilms aren't as efficient as
crystaline silicon. An engineer would multiply all those
inefficiencies and put his money on something with a better
probability of payoff, like horse races maybe.

There are many kinds of them for instance from NXP.

What do you want to use a dual-gate for?

NEC used to have some dual-gate gaasfets, which were cool. They are
apparently gone now, along with a ton of other gaas discretes.
Most are gone.

NXP has some low noise dg fets. They are probably easier to use at UHF/
VHF than a hot 10+GHz XXXfet.

I think they have a dual-gate FET symbol, just no models.

In PSpice I have it down to totally effortless ;-)

Don't be vague, just tell me how ;-)

...Jim Thompson

Hello Jim,

Open the symbol editor.
Place 4 pins.
Right-click on each pin to edit the netlist order to the order in the
.subckt-line.
Draw some nice graphic around it.
Write BFXXX into attribute "Value". Edit -> attributes
Save.

Place this symbol in the schematic.
Change BFXXX to BF998
Include the model file with a SPICE-directive
.lib name_of_file

Wire the complete circuit.
RUN the simulation.

I have used BFXXX in the symbol, because I had in mind to use it for BF996,
BF999, BF???.
If I had used BF998 in the symbol editor, I wouldn't have to change it
later in the schematic of course.
It's also possible to make a symbol only for the BF998.
Last but not least you can already specify the model file in the symbol too.

Best regards,
Helmut

Thanks, Helmut!

Suppose I make parts/symbols as in...

http://www.analog-innovations.com/SED/SubcircuitImportByNetlist.pdf

where "MODEL" is subcircuit name.

Does that work in LTspice, and can I change "MODEL" in the schematic?

Apologies to OP, seemed to have hijacked your thread, but please bear
with us here...

You missed the syntax of K1 and the ease of plotting BH Curve.

Although I laud LTspice for using MKS units it can get confusing,
going back and forth...

Hc = 1.251 Oe = 99.55 A/m
Bs = 1.202e3 G = .1202 T
Br = 85.14 G = .008514 T
Area = 3.27156 = 327.156e-6 sq m
Path = 12.90399 = .129039 m
Gap = 0 = 0 ??

B from Gauss to Tesla divide by 1e4
H from Oersted to Amp/m multiply by 79.57747

then in LTspice you must plot the following 'formulas' to get the BH
Curve:
H=NI/pathlength = 1550*I/1A
Bup = (.1202*(1550*I(L1)+99.55)/(abs(1550*I(L1)+99.55)+99.55*13.12) +
1.94779e-3*I(L1))/1A
Bdn = (.1202*(1550*I(L1)-99.55)/(abs(1550*I(L1)-99.55)+99.55*13.12) +
1.94779e-3*I(L1))/1A,
,or both, but doesn't work so well
Bmag = (.1202*(1550*I(L1)+99.55)/(abs(1550*I(L1)+99.55)+99.55*13.12) +
1.94779e-3*I(L1) + .1202*(1550*I(L1)-99.55)/
(abs(1550*I(L1)-99.55)+99.55*13.12) + 1.94779e-3*I(L1))/2A

Can't remember if those are ceneric constants, or constants just for
THIS model. I either get the 'going up' side or the 'going down side'
but nothing like I used to get with PSpice DOS version.

By the way, you'll find that LTspice's curve fit for the Chan model is
excellent! PSpice's Jiles-Atherton model used to make hour glass
shaped hysteresis curves that were incredibly difficult to make
square. But, LTspice does fairly well, by just supplying two terms
Bsat and the Br [where it hits the axis] and you get a decent looking
curve.

Jim, THAT's uncharacteristically vague.See the reply to Jamie for the
way to make LTspice do similar plot to what PSpice DOS version used to
do. I say 'similar' because I have not been able to get the ends of
the curve to touch each other, get close, but no cigars..

Don't be vague, just tell me how ;-)

Hello Jim,

Open the symbol editor.
Place 4 pins.
Right-click on each pin to edit the netlist order to the order in the
.subckt-line.
Draw some nice graphic around it.
Write BFXXX into attribute "Value". Edit -> attributes
Save.

Place this symbol in the schematic.
Change BFXXX to BF998
Include the model file with a SPICE-directive
.lib name_of_file

Wire the complete circuit.
RUN the simulation.

I have used BFXXX in the symbol, because I had in mind to use it for BF996,
BF999, BF???.
If I had used BF998 in the symbol editor, I wouldn't have to change it
later in the schematic of course.
It's also possible to make a symbol only for the BF998.
Last but not least you can already specify the model file in the symbol too.

Best regards,
Helmut



Thanks, Helmut!

Suppose I make parts/symbols as in...

http://www.analog-innovations.com/SED/SubcircuitImportByNetlist.pdf

where "MODEL" is subcircuit name.

Does that work in LTspice, and can I change "MODEL" in the schematic?

Whoever helps Jim learn to use LT Spice should charge him for it. His
only goal is, he admits, to make money.

I think LTspice can do the same thing.  Just think your way thru
parameterization.

Jim, THAT's uncharacteristically vague.See the reply to Jamie for the
way to make LTspice do similar plot to what PSpice DOS version used to
do. I say 'similar' because I have not been able to get the ends of
the curve to touch each other, get close, but no cigars..

found it! see the reply to myself to Jamie.

Anybody have some experiences they would like to share regarding the design of film heaters?

My other contention is that if you are going to design a heater a complete analysis of everything the heater is contact with is in order.



My contentions remain contentious if not in actual contempt as of this writing ;-)

Thanks! I remember working with Minco in the late 80s on a "profiled" heater. I was sure they had a nice summary of the design process somewhere.

Thanks much to all who have weighed in my topic. I think I have the info I need to move forward with a nice array of possible solutions.

Fracking is a major environmental pollutant as well as a massive

waste of natural resource needed for more essential agricultural

production.

Silly left coast loonies. The pollution is tiny compared to
mining and

burning coal. And, once a well is in, the land area used is tiny
too.

That is a bunch of bull and you know. Underground aquifers and
their feeds by surface and subsurface cracks are un-mappable!

Fracking happens deep. I don't think any aquifers have been
polluted.

The reports of aquifers being polluted have all been discredited.
The stuff in "Gasland" turns out to have not been caused by
any hydrocarbon drilling at all.

The pollution issue is known to be there and is impossible to predict
beforehand. They use more than water for fracking. Fracking has also
been implicated in earhtquakes.

Pretty much. The materials used are in a pretty fair state of control.

What's obvious is that you and that other simpleton are not very good at engineering.
