Re: EM Drive

Okay...your post was about "Dark Matter "; not energy: Dark mater is one of those theories that I never considered as having a solid base, a theory born just on the need to mathematically satisfy an imperfect modeling of the universe due to our still limited understanding of the space time fabric, ...

Re: Dark matter theories

With the recent discovery of the probability of many tines more galaxies out there does that not put a kink ito dark matter Hypothesis? :?: Personally I would say yes. According what I read they expect to find thousands and thousands more once the survey is complete. That indeed should put a dent i...

Dark matter theories

Dark mater is one of those theories that I never considered as having a solid base, a theory born just on the need to mathematically satisfy an imperfect modeling of the universe due to our still limited understanding of the space time fabric, of the emergence of mass and of what the heck gravity an...

Re: Vortex rocket engine: lighter, more efficient, more reusable

I guess I would be curious to know comparatively how much of a problem heat is in the turbines vs the combustion chamber. Heat in turbines has always represented the majority of engineering headaches. Any increase in temperature effects the very basic proprieties of any metal. In the case of a rock...

Re: Vortex rocket engine: lighter, more efficient, more reusable

Too late for them to carve a niche in the market I believe.
Their ingenious idea advantages are being eroded more and more by alloys developments and the new rocket engines generations.

Re: Renaissance Fusion

To add even more pain, it seems now that Wendelstein team will not be able to use Deuterium into the 7-x machine until at least 2023, due to "the time needed to full fill all German regulations for the use of Deuterium". No kidding, 4 more years....... We finally start to have the materials, the pro...

Re: Cross Border Power / XNRGI

Very interesting idea. At 0.5 Kwh/kg (and 1.8 Kwh/lt !) they start to become a real interesting solution for applications like electric planes and robotics. For general application where weight is not a big concern (like cars and back up power solutions/load levelling) I believe that all what will m...

Re: Renaissance Fusion

I love stellarators as a research tool. I have been following the Wendelstein development since 2004, I have read most that has been presented and/or published during the last 14 years of development, and I can tell you all that it has been an engineering nightmare in almost every single aspect of c...

Re: Direct O2 evolution in collisions of carbon dioxide with surfaces

How much does it erode the impacted surface? And I presume ambient pressure has to be very low, of the O2 is likely to quickly react with the released carbon. Quote from article: "All experiments were carried out in a custom-made low-energy ion scattering apparatus34. The CO2+ ion beam was extracte...

Re: Direct O2 evolution in collisions of carbon dioxide with surfaces

Does the character of the surface have any effect on the efficiency of oxygen production? I'm thinking along the lines of a catalyst. And there must be an energy level sweet spot to maximize conversion. That's an interesting point about the catalyst idea. The sweet spot for maximizing conversion in...

Re: Direct O2 evolution in collisions of carbon dioxide with surfaces

How much energy does it take to do that compared to other methods of splitting CO2 into C and O2? It's just a prototype, so I do not expect to have a meaningful efficiency right now if compared to other methods. I guess we will need to wait until they lay out some of the ideas they listed in the Di...

Direct O2 evolution in collisions of carbon dioxide with surfaces

This is off topic on fusion related news, but I stumbled upon it today and I found it ingenious and a proof that science can still surprise in areas one would not expect. Long story short, they was trying to understand the presence of O2 into the CO2 tail of a comets and they though it might come fr...
