Well, if you are not a member of Focusfusion society or an investor, unfortunately there is no chance for you to get an update this year. I am a member and I still did not get mine and there is a delay of a few until LPPX puts it on the website.

BTW. Being a member of focusfusion should grant me a copy of Big Bang Never Happened signed by Lerner. Was it sent to me?

I thought these were the rods:

I mean, these do look like copper rods!

But the only advantage of using Tungsten at this time is to avoid eddy currents. That is, copper is a diamagnetic material, so it tends to oppose magnetic field, so they may change the theoretical expectations of the model and also dissipates power due these eddy currents:

Other than that, I cannot think of another reason since tungsten is more resistive than copper.

Any other idea?

So, there is an upgrade going on FoFu-1, according to LPPX’s twitter, to upgrade from copper to tungsten. So, I am confused now. What is the reason to choose Tungsten?

Weird, just tried to get the file now, and still doesnt work.

This link is not working anymore. The new link is:

The problem with fusion in general is the secrecy of its results. Such doesn`t happen in most of areas of science and nowadays there are great databases with free access to preprints or updated preprints with the published results. So, most of research doesn`t give back to the world Christmas gifts, so it is expected that people do not care about it not pressure for more funding.

This is the purpose of websites like http://arxiv.org . Lerner posted there, as well many important original papers on his web page, so he opened his ideas for everyone to see and collaborate. This is what LPPX is doing different, giving back gifts to the world.

I wish I could collaborate with LPPX. I became a member of FFS because since it works close to it and I thought I would get more detailed reports from LPPX. I requested Rezwan for the older and more accurate reports, but he didn`t answer me… And, what happened to the December report? Was it briefed already or my email is still not included among the members?

[MTd2]

My greatest Christmas gift is to take part on this project. Merely buying gifts is too egotistical…

And I wish to get more precise reports so that I can help thinking about stuff. 😀

WOW! I just clicked in the correct opition and payed more 30USD!!!! Now I am super poor! :O If you had told me that 10 minutes ago! :O

But, don`t send the money back. I am happy that I contributed, even though I am a bit low on money now….

[MTd2]

OH! I donated instead of becoming a member!!!! :O I am short on money!!!

[MTd2]

I JUST DONATED! I AM A MEMBER NOW!

The donation was done by using my wife`s credit card. (She authorized me, LOL)

[MTd2]

I changed my mind. I will become a member of FFS this weekend!!!!

I guess I was not clear. I referred to the difficulty in achieving 200Torr, not the modeling by itself. What are the technical obstacles to do that? It isn`t clear in the documents I found so far on LPPX. This point causes doubts even with Sing Lee ( I had an email exchange with him). I sent you a Private Message with the last 2 emails. It may be important to you that you look at them ( this is not me prying on results, but something else)…

[MTd2]

I wish I could put my tone in a more collaborative way… In fact, I feel pretty much handcuffed given that the much material available to understand how LPPX aims to achieve their objectives is not written down anywhere or is not available outside the lab`s oral tradition (this is quite normal in any research group).

For example, before downloading Lee`s simulator and asking here a lot of questions, I just thought that just the discharge of a lot of energy with a great voltage would create a lot of current, that is, 2.8MA. But this is not what is required. What is needed is a pressure of 200Torr and such pressure was never achieved by any Dense Focus Fusion device. This is an order of magnitude higher than what is usually assumed as the highest pressure that allows the formation of the pinch.

So, LPPX is different not only because of the axial field, but mainly because of the extremely high pressure of the fuel gas.

So, I`d like to know why is so dangerous to increase the pressure fast?

[MTd2]

I don’t see how I could slow down anything. In fact, if the project is not a complete secret, it means being open to a little bit review and thus actually making it less prone to mistakes, and thus speeding it up.
