Scaled radioisotope positron propulsion | Ryan Weed at Breakthrough Discuss 2018
Interstellar flight using conventional chemical fuel would take tens of thousands of years. Antimatter promises vastly more power per gram, but faces currently …
Hey my sillies, think he's working in classified territory?!!!!!! . Duh A military test pilot, did PhD level work on positrons , lives(d) in Livermore, as in Lawrence Livermore… his toilet paper is probably even classified. Why wouldn't work on making positrons , which are a gamma ray source, be classified? Yeah.. oh, and he's working on a 100W per Kg nuclear battery too,, This is likely all classified stuff.
Right now a Direct Fusion Drive (based on the PFRC) looks much more realistic – which is weird to say when discussing fusion. According to a 2018 paper they can achieve 5 Newtons of thrust per 1 MW generated with a 10,000 ISP. Now that is truly groundbreaking, especially since the DFD can double for electricity generation. It is safe to assume that it can be scaled up significantly for a propulsion system that can generate hundreds of Newtons of thrust for interstellar travel.
One of the problems with fusion is capturing the energy in gamma rays. One needs to capture that energy via pair-production, which is similar to the positron devices mentioned.
Time Index https://youtu.be/HH70-FdP-os?t=950 he is talking about giant lasers, like NIF, they nver fly, but what about two-laser-proton boron (or better HE-3) fusion? They use neweset much smaller petawatt lasers, shooting ultra short laser pulses. This fusion concept works pulsed, many fusions per second https://arxiv.org/ftp/arxiv/papers/1510/1510.02465.pdf
so protons from deuterium, directed by mag-nozzle r giving the thrust ? how do protons get through the dense deuterium and kr 10atm cloud with most of their energy? thanks
Why not as an energy source? I mean its the lower hanging fruit here since you don't have to care about weight. Also going to have to find more stuff of the ExB extraction.
fantastic! looks like the way forward & seems to be the best option of all to date to go far and stop…short of an improbable breakthrough in wormholes or warp drives.
Using Kripton for interstellar Travel, Yes!…ask Clark Kent for any further questions, didn't he know Cryptonite? I love this, hat of and respect for your work.
Very interesting stuff! It wouldn't surprise me if the use of positrons to generate energy makes the idea of fusion power obsolete before it even gets out of the starting-gate. That would mean "goodbye ITER"!
Getting positrons from radioisotopes *has* to be a *vastly* better and easier idea than creating a monster like ITER to *maybe* get to the fusion break-even point. Fusion power isn't even in the same *galaxy* as power generation via anti-matter.

nuclear pulse!!!
If the company had stock, I'd buy some….
Solar power and nuclear power can give enough energy to create antimater.

We were closer to star travel sixty years ago with project Orion.
I understood about every fourth word spoken. Neat stuff, but you're going to have to dumb it down for the public buddy, By a lot!
Some salesman of expensive fog …
Exact same speech he gave two years ago at Tedx….. Zero progress appears to have been made. Great job..
How can a positron catalyze a fusion reaction? I wish he would explain that, as it is very central to the proposal.

Why isn't this mainstream this seems fake

Hang on. DD-fusion too? Deuterated palladium? Is he selling cold fusion?
Say hello to all the people who begin talking with "So…"
small voice: we only use them as they're created
