Simple question, just for fun: A diode bridge converts AC to pulsed DC (without a filter capacitor). If we have pulsed DC then how should a circuit look like which is able to convert this pulsed DC back to AC (without the means of an inverter)?

A diode bridge folds up the lower half wave so the negative wave becomes a positive one. Now what's the counterpart of this? The task would be to fold down every other half wave of a pulsed DC so it becomes AC again.

Hmmm ...

Substitute transistors for the diodes

Why not switched diodes like SCR's (silicon-controlled rectifiers, thyristors)? Like the four ones seen on the four heat sinks hidden under the Stepanov cardboard box?

But I still can't see how this could give additional energy by placing something special between the rectifier and the un-rectifier part.

Hmmm ...

But if in the above mentioned video the label »Inversor« is an ordinary inverter then this inverter would have to stand the full load of the output current. I don't think so.

  If we have a tank ringing up and we tap the voltage at the threshold level of an avalanche diode couldn't we create dc impulses to be transformed into even higher voltages?  Doesn't faraday tell us that the output of a transformer depends on the rate at which the magnetic field changes about a conductor?  If we dc pulse a transformer primary the output no longer depends on ampere turns ratio's.  Wasn't this what Tesla was doing?  He would create a resonant tank using the generator coils as the I and add capacitance to the generator/primary tank unless the capacity wasn't already matched by the transmission line capacitance.  For an avalanche diode he used a spark gap.  This would transfer power from the grid to his transformer primary in the form of high voltage impulses. This pulse would only be produced when the power supply tank voltage reached the breakdown voltage of the gap.  He also used chokes in series with his local capacitance.  This would insure that while the gap was conducting no current flowed from the generator/primary oscillator.  The chokes would allow stable operation of the generator/primary oscillations.  The generator acts as a negative resistance element in a self-resonating oscillator.  After each gap discharge the voltage or what Tesla called pressure would build back up.  The current flow and frequency always stayed stable because only the voltage  of the system was transferred to the Tesla primary.

SCR's can be used too, but they have a higher voltage drop between the anode and cathode and suffer from high conduction losses (waste of energy).

Waste of energy does not matter if we have energy in abundance (due to the preceding circuit stage).

Also, SCRs cannot be turned-off when current flows through them, which leads to switching errors (especially when a non-resistive load feeds the electric current back into the power supply). 

On the other hand this could be an advantage in terms of circuit simplicity.

The turns-ratio stops applying when the current in the secondary does not flow at the same time as the current in the primary

What if the primary and the secondary coil is one and the same? When the primary and the secondary coils are not needed at the same time then one coil only could be sufficient.

(no simultaneity = no Lenz law).

So this means Lenz law does not apply to the Back-EMF created by a coil. What if we replace the odd battery symbol in the above screenshot with a (DC-pulsed) coil? I call the battery symbol odd because maybe this battery symbol symbolizes just additional energy (from Earth), not a real battery.

And I'm still looking for a FE schematic which neither wastes my equipment nor my time, means one that works at the first go. Ideas?

Zeitmaschine: I've had nothing but hell trying to tame thyristors using a raspberry pie. The problem is always a ground loop in the circuits protecting the pie. So I use npn and pnp transistors, but once you speed the pulse rate up, switching errors kick in.
So if anyone has a good circuit for driving thyristors, I'm all ears and eyes.
After all - thyristors can switch killowatts very easily and they are relatively cheap.
In fact thinking about it, has anyone got a good pic or stamp circuit that switches in the mhz range?

Google & Facebook & JewTube Alliances with intelligence to make privacy obsolete

Google Ties To CIA
Robert David Steele - "Google took money from the CIA when it was poor and it was starting up."

In June 1999, the then up-start Google received a $25 million round of equity funding led by Sequoia Capital and Kleiner Perkins Caufeld & Byers, the latter of which the CIA’s In-Q-Tel had developed a close relationship with to advance priority technologies of value to the intelligence community.

Google Ties To NSA

2008 - the NSA awarded Google a $2 million contract. “NSA bought four Google search appliances, two-years replacement warranty on all of them, and 100 hours of consulting support.” Google is also providing the search features for a Wikipedia-style site, called Intellipedia, on which agents post information about their targets that can be accessed
and appended by colleagues. In 2010 - Google is teaming up with the National Security Agency to investigate the recent hack attack against its network in a bid to prevent another assault.

Facebook Ties to CIA

Facebook funds came indirectly from a corporation with strong CIA ties. It’s a long chain of association: once Facebook begins to take of, venture capital frm ACCEL gives Facebook $12.7 million. One of the 18 member investors of ACCEL, James Bryer, is also on the board of a venture capital frm called NVCA. Sitting on the board of NVCA with Bryer is Gilman Louie, who is on the board of In-Q-Tel.

Changes to Privacy

People more willing to share private information with friends and strangers indiscriminately
– Current and previous employment
– Friends, family, address, contact info
– Hobbies, interests, political views & afliations
– Photos of everyone & everything
– Relationship status, home town, education
– Broadcasting private thoughts, current activities,
current location

Google Apps
- Picasa
– Encourages people to share photos online
– Tag photos online by participants using facial recognition. Teach Picasa and Google to better recognize faces, yours and your friends.
-  Google Earth & Google Maps
– GPS on smart phone to get directions, now Google knows where you are and where you're going
 
Social Media & The U.S. Government spy own citizens and jail them

In 2009 - Training course that describes how IRS employees may use various Internet tools -- including social networking sites and Google Street View -- to investigate taxpayers. The U.S.Justice Department released a presentation entitled "Obtaining and Using Evidence from Social Networking Sites." The slides detail several social media companies' data retention practices and responses to law enforcement requests. It notes that Facebook was “often cooperative with emergency requests” while complains
about Twitter’s short data retention policies and refusal to preserve data without legal process.

Profling
NSA is funding research into the mass harvesting of social networks that could harness advances in internet technology - specifcally the forthcoming "semantic web"
championed by the web standards organization W3C - to combine data from social networking websites with details such as banking, retail and property records,
allowing the NSA to build extensive, all-embracing personal profles of individuals.

Profling Continued
Spindex - Microsoft revealed Spindex, a Web service designed to aggregate its users’ various social-networking feeds onto a single screen. The application is a product of
Microsoft’s FUSE Labs, a Microsoft division devoted to building software with a social connectivity focus. We're doing their work for them. We create pages all about ourselves and our friends and family. We describe what we do, what we like, who we are.

Profling Continued
Police and Intelligence agencies used to have to leave their ofces to gather information on people they were profling.
Now they just need to visit a few social media sites and connect the dots.
Social media aggregators like Spindex will only make their jobs easier. It will connect the dots for them.

Conclusion
Ties between Google, Facebook and intelligence tenuous but real Huge amounts of personal (and private?) information at their
disposal. Who is they? Who has access? How is it used?
People have been trained to profle themselves
Even if you aren't profling yourself, your friends and family may be profling you

Is privacy impossible today in JEWSA ?

Hello to all
thyristors have the characteristic to be robust and cheap but are
only suitable for 50-60 Hz even the fast ones do not come up to 5000 Hz
