Re: Mach Effect progress

It could mean a lot if things.
E.g. it could mean that the thing is just jerking back and forth.
It could also mean that you need to increase power as you accelerate.

Re: Mach Effect progress

The "resonant frequency" thing is what I find really off putting.

Re: Mach Effect progress

Once they start doing orbital test launches with Starship, there will probably be plenty of room to have small payloads like these launched for cheap, or even free...

Re: Diamonds turn nuclear waste into nuclear batteries

Unfortunately even without a reactor, you're probably still going to need at least one nuclear certified person on board, and probably all the paperwork related to having a reactor, aside from the greenie opposition. And you need a source of strontium. Agree about the nuclear certified person. As I...

Re: Diamonds turn nuclear waste into nuclear batteries

First that is way to low power. When driving a car easily needs 15-20 kW constant power and an EV like the Tesla Model-3 has 225 to 360 kW maximum Power. For that 225 kW power @ 20W/kg an 11.250 kg (!) battery would be needed. That car would be as heavy as a truck and have a very bad efficiency due...

Re: Diamonds turn nuclear waste into nuclear batteries

Nickle has a density of 10 grams per cm3. Carbon 14 is 1 grams per cm3. So we get somewhere between 1 uW/g and 5uW/g power density. Pretty awful... Now, I have done some digging on my own and what I found to be a near perfect beta emitter in terms of half life (~29 years) and power density is Stront...

Re: Diamonds turn nuclear waste into nuclear batteries

It's not carbon-14 alone. They plan to use a blend of different isotopes to achieve different power density targets. A table was provided in their investor pack, but that's been taken offline. Some have not only shorter half lives but also generate more energetic beta particles, so even if present ...

Re: Diamonds turn nuclear waste into nuclear batteries

ThunderF00t also has a great debunking of this. It is a complete nonstarter. Unfortunately "tech journalists" these days are not tech savvy at all and unfortunately also not real journalists. Any real journalists would have for one requested information about the numbers and would have done some num...

Re: Diamonds turn nuclear waste into nuclear batteries

Well one gram of Carbon 14 should (by my calculation) emit 2x10^11 beta particles per second at about 49 keV each. So we are talking 9.8 x 10^12 keV/second or 3.528 X 10^16 keV/h and that translates into 0.00157013295726 Wh. So you need a 1kg for 1.57 watts of power. That is assuming that their syst...

Re: Diamonds turn nuclear waste into nuclear batteries

From what I see they have partnered with Orano, which is a very large company that does nuclear fuel and nuclear waste processing. I am not sure how much Orano has invested in them, though. My biggest problem with them is that there are no numbers. I am most interested in the power density. From all...

Re: More Helion Energy news....

Helion is very tight lipped about these things right now. What I can say is that their new reactor is significantly larger than Venti. Venti was supposed to get close to notional break even with 20 Tesla magnets in Phase 3 of Alpha, which they skipped in favor of the new prototype. So you can make y...

Re: More Helion Energy news....

Nice to see you back on TP after the break Skipjack! Thanks bud! It is good to be back. After all these years, everyone here is a bit like extended family to me. Hope to see more people return now that the forum is back up! It is interesting what you report about Helion Energy as they have really b...
