Re: Apologies for the long down time

Could it be, perhaps fitting, that the site came back up today. May the Forth be with you...

United States Space Navy...

I don't know... if the navy is able to start building starships, they might be able to put together a solid case to take over the air force. One 90 year old instance of interservice rivalry solved! :lol: Makes a good argument for the creation of the United States Space Navy! Maybe they might recall...

Skyhook and Earth's Magnetic field

Hypersonic sky hooks never made any sense to me, how do you keep a rotation body up there if you're using up some of it's momentum to take additional space ships up? The Skyhook concept includes a section of the tether that can be electrically energized (one way, with electrons emitted from one end...

Isn't a wiffleball denier a pitcher with a wicked curve, who can prevent the batter from ever hitting, striking them out, and winning for their team?

Re: But the PDO is cyclic?...

But since the periodic nature of the PDO means that we have hit the highs and lows before, why haven't all the clathrates been cooked out previously? Thanks. METHANE HYDRATE STABILITY AND BREAKDOWN The ocean temperature has to reach a base threshold. I understand the concept that the clathrates wil...

But the PDO is cyclic?...

BTW if the PDO is a "surface" phenomenon (1,000 m) why should it affect methane release? Clathrates occur at depths between 300 and 2000 metres. But since the periodic nature of the PDO means that we have hit the highs and lows before, why haven't all the clathrates been cooked out previously? Than...

Fuel Tanks...

For the prospect of the Navy, do you think... due to the availability of fuel from the seawater? Or is the process of extracting... That depends on the size, weight and complexity of the equipment needed to do the deuterium separation. Maybe a consideration for the largest of ships, thus making the...

Scaling assumptions...

VERY promising. It looks like the core scaling assumptions outlined by Bussard in the Valencia paper are holding up. My takeaway from discussions a few months back about the current round of funding, that I had with a source I trusted, was that this next round of contracts IS designed to actually p...

Hmmmm.... Fusion....

What does the general public think fusion... means? Why? A close shave. Gillette "Fusion" razor. An entry level car. Ford "Fusion" ("Drive it like you mean it") Now "nuclear fusion"... Unfortunately, that contains the word "nuclear"... That comes with its own connotations... Which is why I like the...

Worth the few minutes of dreaming...

Maybe that explains why I very rarely buy a ticket... And even then, I'm not likely to spend more than a couple of bucks on it.

Re: Shovel ready?...

So did this really happen? According to my source, who was in a position to believe, it was going through. That is why I asked the question in the first place. But I haven't seen anything on this board or anywhere else to confirm... Which I had. (Hope it is all just in the contracts delay right now...

Mostly a comment on acceleration...

I like this technology for a maglev vehicle: ... Yes, I had followed Inductrack for a while for ~stage 0 rocket launch. I wasn't trying to say that the current EMALS was the only technology out there, just that the acceleration forces, from my experience, wouldn't necessarily be in the 1 - 1.5 G ra...
