Re: Company (Quaise Energy) plans to use fusion technology to drill for geothermal

Earths heat energi content stems from thorium and uranium decay. Uranium (both 235 and 238) and thorium has a halvlife even if it counts in many billions of years. This minuscule energi evolvement adds up over a huge volyme and is what makes Earth a geologically active planet. If to much heat is ex...

Re: Company (Quaise Energy) plans to use fusion technology to drill for geothermal

I haven't heard about drilling causing earthquakes. Fracking, yes, depletion of underground water tables and oil deposits, yes. Drilling per se, not that I know. Can anyone give some examples? Unless there are examples of this, or at least a credible theory regarding a relation, I think running to ...

The real strength behind Quaise is the fact that if it works as predicted they can drill holes 100 times faster than anyone else.
Great! Lets make earthquakes 100 times faster! :mrgreen:

Re: Company (Quaise Energy) plans to use fusion technology to drill for geothermal

I once calculated that there was not enough geothermal flux, even at a 100% conversion efficiency, to power the world’s energy needs. So to do more, we would need to extract STORED energy. What that would do to earthquakes, I hesitate to speculate.

I'm probably stating the obvious here, but these organizations are anti-human. Any technology that continues to allow humanity to grow and expand will be opposed.

Either they have not turned it on yet, or it is not working...
Launched 11 Nov 23, needs 3 to 4 months (IIRC) of background data before “ignition”. So, not on yet.

Re: EM Drive

If the baseline data demonstrates ALL plausible external forcing functions, then mN level forces over time should be distinguishable, irrefutably.

Re: Sintered metal objects from a standard FDM 3D printer

“ In the case of copper, the highest density achievable would be about 97 density with 15 percent shrinkage, but shrinkage can be kept to under 7 percent with 10 to 12 percent porosity.” So, definitely not vacuum tight. And I don’t see anything about printing superconductors. Nitrogen (LN2) doesn’t...

Re: SpaceX News

Specifically, it was the reason for the attempt being delayed by one day. They de-stacked and swapped out the actuator (actually, all 4 I think I read). Not only not the cause of the explosion, but also the explosion probably made the issue irrelevant ;) Then again, the effectiveness of the grid fi...

Re: SpaceX News

There was an issue with an actuator for one of the grid fins. Where did you see this? I am still seeing a lot of speculation regarding the FTS triggers for both Booster and Starship. We may have to wait until SpaceX releases more information. In any event, the launch through Hot Stage had to be a g...

I've suggested it before and will suggest it again, probably: delivery by dirigible. :wink:
And heck, the product being delivered makes the gas that floats the ship!

With Starship using steel for the structure, I wonder how many tiles it can lose before catastrophic failure.
They have a blanket under the tiles. I’ve wondered if the blanket itself (or a thicker one) would suffice or if they could make do by adding spray cooling of the steel.
