I didn't miss it.

In case you didn't know, acceleration is not velocity. It is the rate of
change of velocity.

If he has written v =Ldi/dt as opposed to f=Mdv/dt, he would have been
correct.
but for a constant velocity, F=MA becomes 0 for ANY mechanical resistance.
V=RI is not zero for constant current for any (non-zero) electrical
resistance.

M.T.09.05-08.Tanskan insinööriliitossa uskotaan uusiutuvaan energiaan
"Energiasuunnitelma 2030"- nimisen raportin (ES). Sen tekoon osallistui 1
600 insinööriä ja muita energia-asiantuntijoita. ES:stä sijoitukset
uudisenergiaan ovat ekologisesti ja taloudellisesti hyvin perusteltuja.
Samoin varteenotettavia vientimahdollisuuksia. Uudisenergia tulee rajusti
lisääntymään. Tanska pääsee v.2030 pitkälle kokonaan uudisenergiaan.
Arvellaan 50% osuutta jo silloin.

Kasvihuonepäästöistä poistuu 60% ja näin säästyy 15 miljardia kruunua/v.
Investointitulojen kasvuksi 30 miljardista 160 miljardiin v-30. Säästöä 845
petajoulesta 580 petajouleen. Suomessa 1 400 petajoulea. Teollisuus voi
vähentää 30%! Säästöä tästä 6 miljardia kruunua. Takaisinmaksuaika
investoinneista 6-7 vuodessa. Tähän budjetti 107 milj. euroa. Rakennusten
energiankulutuksen puolitus 2030. 15% tulisi aurinkoenergiasta. Sähköstä
pois 40%. Jo 2020 jälkeen rakennettavien talojen arvioidaan olevan JO
energianeutraalin. Energiasäästösäätiöön pannaan miljardi kruunua.

Liikenne Tanskassa vielä kasvaa 2%/v. Siitä tullaan poistamaan 20%
nykytasosta korvaamalla siitä biopolttoaineella. Viidennes sähköautoihin.
Rautateille lisäystä. Verotus suosimaan ympäristöystävällisiä autoja.
Kuljetuksiin 200 miljardia kruunua l. 27miljardia. Vähentäen
terveydenhuoltoa, ruuhkien ja ympäristönsuojelun menot. Huomattavasti
nykyistä suurempi osuus uusiutuvista lähteistä. Tuulipuolella Tanska suuntaa
merien offshoretuulivoimaan. ES:n tavoite on kaksinkertaistaa tuulivoimaansa
sähköstä huikeaan 60 prosenttiin!!!

Aurinkosoluille 2030 ennakoidaan 2% ja aaltovoiman 5% sähköntuotannosta.
Aaltovoimaa pidetään erittäin merkittävänä. Biomassasta ennakoidaan 30%
v.2030. Mukana biopolttoaineiden 20%. Biokaasuun luotetaan, samoin uuden
sukupolven biopolttoaineisiin. Näihin Tanska sijoittaa paljon.
Biopolttoainesektorikasvaa 20 miljardiin kruunuun 2,7miljardiin euroon.
Kolmannes 2030 voimaloista käyttää jo tehokkaita polttokennoja ja
lämpöpumput ovat arkilaitteita. Tutkimuksiin nostetaan 350 miljoonasta
miljardiin kruunuun. Valtio kevittää uudisenergiainvestointiriskittömämpiä
syöttötariffeja. "Saastuttaja maksaa periaatteella!"(Suomessa ydinalalle
moinen olisi ennenkokematonta!)

Suositellaan luopumista verotuksesta joka estää siirtymistä fossiileista
uudisenergiaan. Lentopetrolille veroa. Tanskassa on oleellisesti helpompaa
toteuttaa uutta energiapolitiikkaa. Valitettavasti meillä ei edelleenkään
olla valmiita sellaisiin toimiin, joilla kokonaisenergian kulutus saadaan
selvään laskuun ja uusiutuvan energian ja sitä tukevan teknologian käyttö
vahvaan nousuun.

If it won't damage the rest of the product then a few seconds in the
microwave oven would do the job too.

It isn't easy to beef up a camera flash to get enough power to screw up all
the different types of RFID tag, an alternative inverter can be built from a
small SMPSU transformer such as found in a TV-STB or the auxiliary switch
supply transformer from an ATX-PSU.

The best type of transformer is for transistor drive, not an SMPSU chip, as
it has a feedback winding designed to drive the B/E of a transistor, of
course the 5 or 12V winding is used as the primary (collector winding) and
the original high voltage primary becomes the secondary.

The final circuit resembles that of a typical camera flash inverter but on
most that I've built it was found necessary to add a regulation circuit
otherwise it tends to draw an arc between the pins of the HV winding.

Or, more succinctly:

Negative resistance
From Wikipedia, the free encyclopedia
(Redirected from Negative differential resistance)

He could simply have said that that was what he meant.

He probably assumed that it was obvious. I've heard the term used
occasionally (e.g. w.r.t. tunnel diodes or UJTs), and I've never seen
anyone feel the need to add the "differential" or "slope" part.

Except that it wouldn't support his view that the current would increase
without limit.

Sure it would (unless you genuinely believe that, by "without limit", he
was claiming that the current would rise to infinity).

For a constant supply voltage, positive resistance results in
negative feedback and stable equilibrium, while negative resistance
results in positive feedback and unstable equilibrium.

OK, I can nitpick too - we're not even talking about a "negative resistor"
- obviously, such a thing can't exist. What we're talking about is
"negative resistANCE", which is a characteristic of various things,
notably, and arc, a UJT, or a tunnel diode.

I still can't get my head around the fundamental reason why there's
only one kind of positive resistor but two kinds of negative resistor.

I think I can add to the confusion:

We are thinking "number line like this:

-3, -2, -1, 0, 1, 2, 3, ..... really big, infinite, -really big ...

There are two ways to get to a negative number.  One takes you past
the "infinite" value.  In truth though. we have a 2D world we can
avoid hitting the singular value by going a little reactive.

.................................
.................----------......
..-...0...-------....*.....------
...-------.......................
.................................

As often happens in math, the pole is the center pole of a spiral
staircase.  You have to go around the pole twice to get back where you
started.

Don't you remember how much grief certain parties gave me for using
the term "infinite"?

(I don't know why I call them parties, when they never seem to have
any fun.)

Some people are concerned on theological grounds any time the subject
goes to that of the infinite. They have near fits when you start
comparing the sizes of infinities and their heads explode if the
question of whether there is an infinite number of infinitudes. In
this case we merely have a 1/0 sort of infinity or a simple pole.
This is not to suggest that all poles are simple. I work with one who
does quantum physics, but that is way off the topic of this question.

I hope this helps. :

Yes, I used to date a simple pole, and I know exactly what you mean.

If we use, for example, a simple, existent, and readily available neon
lamp like an NE2 (which exhibits a negative resistance characteristic)
as the passive device and bring into existence an active, two terminal
circuit which exhibits the same negative resistance characteristic then
the two will be equivalent and whether the active device needs a power
supply will be unimportant since the same supply will be used to power
the passive neon device.

The two of you need to settle on some terminology.

The terminology is quite settled.

There's the resistance defined by V/I, the large signal, operating point, or
whatever you want to call it 'resistance'. Then, there's the small signal,
differential, or region, defined by dV/dI.

Sylvia is referring to the former, you, the latter. Each definition has
different implications for stability, power dissipation and other
properties of a circuit.

The former being negative makes no sense in the real world, so is
ignored. The latter is known as "negative resistance". The
derivative is understood by everyone with the exception of Sylvia,
and perhaps yourself. This has been made clear many times in this
thread but she refuses to listen.
