Re: We lost so many members :(

In my opinion firstly we should ask Joe what are his plans for the board. If he intends to keep it living as a general fusion board, than there will be the need to: 1) Get additional administrators to handle new members registrations and related issues. 2) Restructure the forum lists to include all ...

Re: Fusion devices are not "nuclear fusion reactors"

Since several decades there is little difference in Greepeace dogmatic environmentalism attitude and religious fundamentalism. I stopped supporting them since 1987 when they used the general hysteria of Chernobyl accident to push (and win) a referendum in Italy that forced the closure of the country...

Re: Fusion in Shipping

From what I understand, they could hold their charge for years if properly disconnected from the circuit without any current leakage through some of the switches somewhere. With a leak value of 1x10-9 scc/sec it means it will leak one cubic centimeter every 320 years more or less. That container is...

Re: Fusion devices are not "nuclear fusion reactors"

After all the hatred and disinformation that media spread in the last years on anything that has to do with the word nuclear, it makes sense that now they need to start to clean the ground to prepare the average person to accept this new tech. It will be fun the day that I will discuss fusion reacto...

Re: Fusion devices are not "nuclear fusion reactors"

I think that is not a bad move. To the average person "Fusion Generator" will sounds pretty harmless.

Re: Fusion in Shipping

This is a bit confusing. They list "30 kCi of Tritium gas" as the capacity. At 9600 Ci/gram that would be 3 grams, no? The 30 kCi is the vessel design, but you do not have only tritium inside as you also have the 90 gr of depleted uranium as wetting material to absorb the tritium, so the 30 kCi has...

Re: Fusion in Shipping

Nice find.
That container has a nominal capacity of 7 sL of tritium gas, that's roughly 1 gr of Tritium.

Re: More Helion Energy news....

The recovery process has of course been tested. It is actually over 95% efficient, but they rounded it down to 95%. That is first hand information. Part of the reason why it works is because of the extremely high beta of the plasma ~1. You are correct that repetition rate is very important for over...

Re: Fusion in Shipping

I have been to the engine rooms of several ships (large and small) and the engines were always very accessible. If there is a problem while you are at sea, you need to be able to fix it right there (if possible with on board equipment). The tritium would likely be stored in relatively small but thi...

Re: NearStar Fusion

I just checked out of curiosity:

Nearstar:

HyperV Fusion
https://ibb.co/xfFfKnc

Same equipment and same lab.
I wonder what really is the new idea behind NearStar that was not tested in the past.....

Re: NearStar Fusion

It seems the same design from "HyperV Fusion" and "HyperJet Fusion" and "PLX experiment". The three shared most of the equipment and facility, and also "Nearstar" seems to share the same equipment and facilities according what I can see on their homepage video.

Re: Fusion in Shipping

I think Helion's reactor would be fine. One would likely remove the tritium storage tanks between tours. So the amount of tritium would be minimal. Ship engines are not generally in easily accessible areas and the idea of tritium handling and transferring between each few trips in a port is also no...

Re: More Helion Energy news....

Their ARPA-E experiments and papers were targeted at ARPA-E, which had specific requirements. Also mind you, they did not stand still but have been improving their recovery technology constantly, since it is a core concept of their design. I mean, this is essentially an electric generator without a...

Re: More Helion Energy news....

There is a lot of precedence in regenerative braking for electric cars, which is already very efficient, despite being mechanical with friction and all that. Some of the technology developed for cars likely benefited Helion as well. E.g. today's IGBT switching is super efficient compared to what wa...

Re: Fusion in Shipping

Most industries are still pretty new to the whole "Fusion technology", their knowledge comes mainly from ITER related news, hence they have the general understanding that fusion will be just a thermal generator like any other generator. I personally do not see any chance for a fusion based maritime ...
