the effect of a capacitor. stores energy and is a static charge . solenoid stores energy in the magnetic field.
how to make power the right way. static needs no current, therefore a conversion between static, then into a coil is the right way to generate power.
cop much greater then using current to make a magnetic field. if u want to talk radiant energy then don't be a stranger..

in this sense I make a static generator by simply powering it with a capacitor... Or a Motor. no battery is ever used to supply the voltage..
in case any of you are interested what I have been up to,, just brows through this stuff.
lol energy u say is not static? I beg to differ...
this guy is the man you better keep a close eye on.. cheers.

how stupid of me... all I need is a linear coil 4 feet long, with a wave effect of 200 mph, and a secondary coil wrapped around the coil windings.. cheers..
are you ready for the next generation tesla pancake coil?
on bifilar coil, fine now a second wound the same way but stout wire,,
this will be the asymmetrical coil you had been wondering about..
its a figure 88888888 cheers... u may make one quad coil, and one bifilar wound in opposite direction... cheers...

Instead of fine and stout bifilar, go straight to a piece of coax. Now that's an asymmetrical coil with a future. :)

I do as tesla said I elevate my negative terminal..
I the increase its capacitance by adding surface area. so therefore my battery shall never run out..

can you please explain how it makes it asymmetrical, or how to build it?
Understanding what is happing with this arrangement is a little more difficult. First, one has to understand that certain fields can be shielded and others cannot. With a coax cable, nothing is shielded on the outside conductor, but the inner conductor is a different story. That difference is what makes such a device asymmetrical.
isn't that what a cook coil inductor is? also described by Edlee?
the magnetic field is then intensified ...
I say resistance alone makes it asymmetrical. and can make one half of a transformer coil to have very little, and the other to pass a strong current..

New planet discovered by 15-year-old internBy Monica Sarkar, CNN
Updated 6:10 PM ET, Thu June 11, 2015
Tom Wagg was an intern at Keele University's observatory when he discovered the planet.
Tom Wagg was an intern at Keele University's observatory when he discovered the planet.
Story highlights
According to Keele University, England, a 15-year-old boy has spotted a new planet
The school pupil was on work experience at the university when he made the discovery
(CNN)Advice to interns: work hard and make your mark. And if you can discover a new planet while you're at it, you could also be pushing the boundaries of our knowledge.
Believe it or not, a 15-year-old boy did just that, according to Keele University in England, UK. While undertaking work experience at the university, Tom Wagg noticed a tiny dip in the light of a star as a planet passed in front of it -- that planet had supposedly not been on anyone's radar until then. The university said it has since taken two years to verify his findings.
"I'm hugely excited to have a found a new planet, and I'm very impressed that we can find them so far away," Tom said, according to a statement from the university. He apparently spotted the planet by scouring the data collected by Keele University's WASP (Wide Angle Search for Planets) project, which scans millions of stars in night skies and searches for tiny dips, or transits, caused by the passing of planets.

An artist's impression of WASP-142b orbiting its star.
Nameless for the time being, the new planet has been labeled with the catalog number WASP-142b, as it's the 142nd discovery by the WASP collaboration.
Invisible to the naked eye and 1,000 light years away, the planet is the same size as Jupiter, the largest planet in the solar system, but orbits its star in only two days. Such frequent orbits make such planets easier to find -- if you can describe the feat as easy.
After the discovery of the planet, astronomers at the University of Geneva and the University of Liege confirmed that it had the required size and mass to be identified as a planet. And the university is planning a competition to find a name.
A star student at a nearby school and a science enthusiast, Wagg had requested the work experience after learning that Keele University had a research group studying extrasolar planets, or exoplanets -- planets that exist around stars other than the sun.
According to NASA, the first exoplanet was spotted in 1995 and 5,000 have been discovered ever since. The space agency says on its website that such findings provide hope in finding another Earth.
oh yea here is a laugh, a 15 year old baby boy gets to discover this absurd revelation :P :P...
sorry folks he did not discover squat!!!

Rosetta’s lander Philae wakes up from hibernation
Rosetta's lander Philae is out of hibernation!
The signals were received at ESA's European Space Operations Centre in Darmstadt at 22:28 CEST on 13 June. More than 300 data packets have been analysed by the teams at the Lander Control Center at the German Aerospace Center (DLR).
"Philae is doing very well: It has an operating temperature of -35ºC and has 24 Watts available," explains DLR Philae Project Manager Dr. Stephan Ulamec. "The lander is ready for operations."
For 85 seconds Philae "spoke" with its team on ground, via Rosetta, in the first contact since going into hibernation in November.
When analysing the status data it became clear that Philae also must have been awake earlier: "We have also received historical data - so far, however, the lander had not been able to contact us earlier."
Now the scientists are waiting for the next contact. There are still more than 8000 data packets in Philae’s mass memory which will give the DLR team information on what happened to the lander in the past few days on Comet 67P/Churyumov-Gerasimenko.
Philae shut down on 15 November 2014 at 1:15 CET after being in operation on the comet for about 60 hours. Since 12 March 2015 the communication unit on orbiter Rosetta was turned on to listen out for the lander.
More information when we have it!
Rosetta is an ESA mission with contributions from its Member States and NASA. Rosetta's Philae lander is contributed by a consortium led by DLR, MPS, CNES and ASI.

You say that Philae now has "24 Watts available". This doesn't make much sense. The word "available" indicates that you are talking about "energy" in which case the units should be "Watt.hours" or "Watt.seconds" rather than "Watts" on its own: which is a measure of instantaneous power not how long that power is available for.
Such loose use of language doesn't reflect well on the professionalism of ESA.

Such loose accusation doesn't reflect well on the professionalism of Ollie Cox. It is an instantaneous measurement. It's how much power the solar cells are making and possibly charging the batteries. If the batteries charge for say 10 hours at 24 watts then you'd get your rating from the battery as to how many Watt.Hours you have stored.

Michael McClelland says:
14/06/2015 at 18:15
An instantaneous measure is not very useful. The actual energy available would be a much more important piece of information to obtain, followed by the rate and times at which it was accumulated. One has to guess that the message was a fragment that did not encompass these much more important data.

I imagine the solar panels are currently generating 24 Watts (or maybe 24 Watts over and above some minimum required for house-keeping. Perfectly reasonably use of "available".

The comet is spinning - this means the solar panels are not getting constant sunlight. It's also suspected to be in a depression - so peak energy output is likely very different than average.
There was talk when it landed about trying to get the lander to move itself out of the bad landing location. What is the window before the lander is expected to be overwhelmed by the sun's heat?

Shaggy says:
14/06/2015 at 17:51
It makes perfect sense to any engineer or scientist.
If it had 24 joules available then it could only do 24 Joules of work before needing more energy.
However if it has 24W available, then it can do work at a rate of 24 Joules of work every second, much more useful and much more likely to be what was meant. While that power is available it can continue to work.
Such accurate use of language only goes to show how difficult it is to explain science to the masses. Even when what you say is clear, correct and concise some people still can't get it.

Hi Ollie,
I think there is some slight misunderstanding in jargon going on here. A battery would as you say have e.g. 24Wh available, and, given its rated maximum current and the voltage it has at full charge, deliver (not "have available") a certain maximum power.
For solar cells, nomenclature would be a bit different, as a solar cell by its own does not deliver any power, no matter the rating: Light impinges on the battery and results in a voltage appearing on the terminals of the solar cell. Loading the terminals will result in a current to flow and the voltage to drop - at a specific "maximum power point", i.e. fine-tuned load on the solar cell, the cell will convert the impinging power most efficiently.
As the impinging solar power is dependent on the illumination level (this becoming high enough is what we'd all hoped for Philae), stating the solar cells now have 24W available is perfectly reasonable and the correct technical jargon.
Hope that helps,
Alex

As Jadzia wrote, that is the power output available from the solar panels, not energy available from batteries. Recall that after a number of bounces in the comet's tiny gravity, it came to rest in the shadow of a ledge or cliff. But the comet has now moved to a point in its orbit where sun is able to reach the solar panels.
This is an impressive achievement for the probe's electronics to survive the months of extreme cold in that shadow.

You should have at least googled "available power". Energy is not a good measure for device capacity as 10 Watt.hours can be spent in a second and nothing prevents us to still use Watt.years for the unit.
Rated average power is annotated to devices as to mean how much can it deliver per unit of time consistently.
Finally they sent the *thing* to space and landed on another weird *thing* and still you question professionalism over a blog post and units?

Ich denke sie meinen die Energie die die Solar Panels generieren.

Such loose accusation doesn't reflect well on the professionalism of Ollie Cox. It is an instantaneous measurement. It's how much power the solar cells are making and possibly charging the batteries. If the batteries charge for say 10 hours at 24 watts then you'd get your rating from the battery as to how many Watt.Hours you have stored.

Who cares about units of power available? The basic unit of measure that is important is the number of hours of full operations and time to recharge thereafter... How much time does our little buddy have???

An instantaneous measure is not very useful. The actual energy available would be a much more important piece of information to obtain, followed by the rate and times at which it was accumulated. One has to guess that the message was a fragment that did not encompass these much more important data.

I imagine the solar panels are currently generating 24 Watts (or maybe 24 Watts over and above some minimum required for house-keeping. Perfectly reasonably use of "available".

The comet is spinning - this means the solar panels are not getting constant sunlight. It's also suspected to be in a depression - so peak energy output is likely very different than average.
There was talk when it landed about trying to get the lander to move itself out of the bad landing location. What is the window before the lander is expected to be overwhelmed by the sun's heat?

It makes perfect sense to any engineer or scientist.
If it had 24 joules available then it could only do 24 Joules of work before needing more energy.
However if it has 24W available, then it can do work at a rate of 24 Joules of work every second, much more useful and much more likely to be what was meant. While that power is available it can continue to work.
Such accurate use of language only goes to show how difficult it is to explain science to the masses. Even when what you say is clear, correct and concise some people still can't get it.

Hi Ollie,
I think there is some slight misunderstanding in jargon going on here. A battery would as you say have e.g. 24Wh available, and, given its rated maximum current and the voltage it has at full charge, deliver (not "have available") a certain maximum power.
For solar cells, nomenclature would be a bit different, as a solar cell by its own does not deliver any power, no matter the rating: Light impinges on the battery and results in a voltage appearing on the terminals of the solar cell. Loading the terminals will result in a current to flow and the voltage to drop - at a specific "maximum power point", i.e. fine-tuned load on the solar cell, the cell will convert the impinging power most efficiently.
As the impinging solar power is dependent on the illumination level (this becoming high enough is what we'd all hoped for Philae), stating the solar cells now have 24W available is perfectly reasonable and the correct technical jargon.
Hope that helps,
Alex

As Jadzia wrote, that is the power output available from the solar panels, not energy available from batteries. Recall that after a number of bounces in the comet's tiny gravity, it came to rest in the shadow of a ledge or cliff. But the comet has now moved to a point in its orbit where sun is able to reach the solar panels.
This is an impressive achievement for the probe's electronics to survive the months of extreme cold in that shadow.

You should have at least googled "available power". Energy is not a good measure for device capacity as 10 Watt.hours can be spent in a second and nothing prevents us to still use Watt.years for the unit.
Rated average power is annotated to devices as to mean how much can it deliver per unit of time consistently.
Finally they sent the *thing* to space and landed on another weird *thing* and still you question professionalism over a blog post and units?

Hi Rosetta-Team
awesome, unbelievable great news !! I´m so happy to hear from our little Hopper
Wow u should get in contact eith kal abraham th guy who created techyronics.... He could use ur help in writing up theories for techyronics...
In fact i would say Flack techyronics ur ten times better than abrahm at spitting pseudo science u should create ur own techyronics

how to create a variable emf, and a abrupt spike or reversal, by use of constant rotational speed..
by use of three phase shifts,, and a change in direction in the induction coil.. voltage change, pole reversal. all with constant rotational speed. and yet I wish to do exactly that on a linier design..
theory on another type of motionless generator. as apposed to relative motion.
