Focus Fusion?

[catsmate]

You realize the comma is not a decimal point in the US? The only place I see anything resembling 1.5 on that page is the description "1, 5 g in glass bottle". I think that means 1 >and< 5 gram bottles. From my US location I see prices quoted in dollars. 1G sample: $47.40, 5G sample: 159.00.

Hmm, here's what I see:


I assume the sample is 1.5 grammes and the price refers to individual (€117) and five unit (€380) packs.

Cheap for nuclear fuel even at current prices. And I'm pretty sure I could scale this industrially for a 100X reduction in cost. It's amazing how much cheaper things become when you do them in 1000 kg batches.

And what is this optimism based on ? Currently 11B is relatively cheap because it is effectively a waste material.

Boron is cheap and abundant out of mines right now.

Sigh. Isotopic separation isn't.

If we replace the entire energy consumption of the world with focus fusion, we will be using 10% of current boron production.

Let's see some numbers.

Getting it from seawater is just for the far future, to show we can’t easily run out (and it can’t be monopolized either.)

Evidence this is practical?

As I said before, the cross section (or reaction rate ) for the B-10 reaction that produce neutrons is tiny.

Evidence?

As other posters have pointed out, separation of B-10 from B-11 is easy to do.

No actually it's not.

The high present costs for both the compound decaborane and for B-11 are purely due to small demand and laboratory-scale production. Industrial production is orders of magnitude cheaper.

More unsupported claims.
