Roger - They remove the sulfur from my asphalt before they burn it. Environmental issues you know. And whatever the exact savings will be by heating with a BFR instead of burning asphalt, it will be a huge number. My post really drives to the point that value of the BFR is so great that we meer mort...

A grand discovery.

Sitting here in front of my computer, Googleing, I have just discovered 8.67E+10 barrels of crude oil. What’s more, this is oil that is or will already be at the refinery, so I don’t have to drill or pump or ship or transship it to anywhere, simply refine it and sell it. This oil is the seven percen...

I wonder if we are on the same page regarding the objective of WB-100? What is the objective and what should it be? Sure, WB-100 is a proof of concept machine, but if that is all it is, and we use 5 years to prove the concept, then that just makes us 5 years further behind in our energy dependence o...

Well shucks... I was hoping for something applicable to over the road trucking as I have heard that that industry uses ~25% of our petroleum. Half meter radius is really good, but intermittent operation is really bad.

Well, maybe he's no longer tied up in committee all hours of the day and has a little time at his computer. I dare say he's got things to do however.

John- I didn't make the claim, but one trail of logic would go like this. BFR scaling is really B^4*R^3 as apposed to R^7 which is most often used for convenience as it is thought that B can be scaled as R. Since the scaling depends on both B and R, and since R^7 ~ 17.1 for R=1.5, then B is also pro...

OK, if power losses do scale as B^(1/4)R^2 it does make sense to keep R small and drive the magnets to high power. But iirc, 0.5 m radius is to small to allow cooling for superconducting magnets and even if not, a small reactor with magnets driven to the limit is nothing but an intellectual curiosit...

What makes you think net power is attainable at 0.5 meter radius? Dr. Bussard's patent as quoted above says, "the minimum practical size for DD systems is about R=1.5-2 m,..." What have you learned that Dr. Bussard did not know when he patented his device? And if you mean DT fusion, please don't go ...

Gosh, I thought he meant that the electron density was important because when to dense, the electrons provide a discharge path between the machine and the wall.

Re: What do we know about WB-100?

Roger, Thanks for the link, the information re-enforces my concern, which, as I wrote initially is: But I'm really most concerned about the question of radius. How sure are we that 1.5 m is right, and how much more does another quarter meter cost. That is to say, "If 1.5 m doesn't achieve net power,...

I stand Corrected - This is a Quote from the above linked patent. The smallest size of practical interest is that at which the device will yield net power from the fuel combinations chosen for use. It has been found that the power output of these devices scales approximately as the 7 th power of the...

Its tricky. But fortunately is has been hashed out.

What do we know about WB-100?

I mean, what do we really know about WB-100? R = 1.5 m, Target Power = +100 MW, ??? What else? And by what else, I include the question of what alternatives will be built into the experimental capabilities? I am concerned that like so many efforts in so many fields, we may see a high fraction of suc...

With a scaling of Pf~B^4, this mean that with a 1.5 m radius, we could produce 16000 Gwatts, in 20ms pulses for 2 seconds!
