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 ext...

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...

Re: SpaceX News

As you said payload would be smaller. If I remember correctly the total mass ratio difference for a DV=7.5km/sec with a 300 ISP fuel for a SSTO to a TSTO would be roughly 20 (SSTO) to 5 (TSTO). That means you loose 4 times the amount of mass you can bring to a DV=7.5Km/sec. And because the "mas...

Re: EMC2 news

So, any consensus on the contents of the patent application document from those who are knowledgable enough to be able to speak about it in an informed manner? Your thoughts Tom Ligon? or ??? It's quite an interesting patent and opens a plethora of possible different road to a commercial product (b...

Re: SpaceX News

Sorry guys , no little green men or super secret squirrel satellite. It is oxygen ice from inside the nozzle on stage two when the turbo pump runs a pre-chill cycle before startup, hence the blueish hue to it. :mrgreen: It falls on top of stage one then falls off. Also stage one pre cools before f...

Re: SpaceX News

S1 MECO is at T= +2:40. I am speaking about the object at T=+6:02. Also at that moment the S1 is no where near stable orbital altitude, but that object does look quite big and it doesn't really look like a piece of ice. IIRC, the 1st stage would peak in altitude somewhere below 120 km. Unlikely to ...
