Until it crushes. Not all aerogels are strong, and in the picture we can see the guy bending it. And even the strength of "strong" aerogels is often overstated - they're high strength for their weight, but not for their volume.

Comment Re:Cheaper? (Score 2) 33

I fail to see how it's at all like composite building - it's a moulded product. Also note: frozen and freeze dried for two days. So if you want to make boats out of the stuff, you have to amortize in the cost of two days (per unit) usage of a thermally-regulated vacuum chamber large enough to put a boat in, which is a pretty expensive piece of kit.

Also, how long is the sonication process?

Making boats or surfboards out of the stuff sounds kind of pointless. As you already clearly know, the ideal boat hull is a twinwall composite, where you have composite layers of high tensile fabric bonded to either side of a lightweight foam or honeycomb core - the latter existing primarily to space the former out. If you replace the inner layer with aerogel, you're only cutting out the weight of the foam or honeycomb - and foams and honeycombs are already quite light. I mean, you'd save some weight... but enough to justify the cost and difficulty?

I guess if you're going really upmarket... after all, some people buy Monster cables ;)

Aerogel is of course nothing at all like loose-fill cellulose insulation. But no, it should not pose a fire risk either. Depending on the type, aerogels are generally considered either fire retardant or non-flammable; even if they're made of something that "burns" on a macroscopic level, there's so little "something" there to burn that the flame barrier properties that they provide generally well outweighs the heat output of their own combustion.

Comment Re:"sexual misconduct"? (Score 1) 182

Yes. Suddenly it occurs to the SJWs that perhaps the standards we impose on minors should now be imposed on people that are supposed to be adults.

I can understand the power issues with letting adult students consort with teachers. Although banning such relationship has not been the rule previously. It simply wasn't the standard.

Now the standard is changing.

So things that were once thought perfectly fine are now suddenly "illegal".

Perhaps a memo should be distributed to everyone regarding the new rules.

No. It sounds like a bunch of cry babies whining that they got hit on. Some of it sounds potentially genuine and a lot of it sounds like the re-introduction of Victorian prudishness. Either way, excusing victims for not coming forward serves no useful purpose. Empowering their victimhood only adds to whatever problem you seem to perceive.

You are contributing to the culture of victimhood that women are indoctrinated into. It's this culture of being prey (social and otherwise), that's at the heart of this situation.

In addition to what bws111 wrote:

Re: the MIT capsule: it's nothing like the Hyperloop Alpha concept (hence my post). SpaceX's test track that they're building is designed to handle a wide variety of vehicles, not just the one laid out in the Hyperloop Alpha concept. IMHO the MIT concept is utterly uninspiring. The drag levels are vastly higher, which are going to ruin pretty much every appealing aspect of the concept.

(but no, the tube has no electromagnets, the MIT design involves induced magnetic fields for propulsion)

Comment Re:The germ theory of disease is settled, too. (Score 1) 470

Actually, that's what we need to be spending our money on and we don't seem to be doing that at all in the "climate science" area. The propaganda machine has been whining that the sky is falling. Once you embrace that, it's simply time to move on. You move on how to fix the problem or survive it.

Chicken Little becomes irrelevant the moment that people start listening to him.

There's some well regarded English figurehead of some sort that's basically been saying this for a long time now. "OK, we're fucked. Now what?"

We have graduated from the "yeah, germs do exist" phase of this particular calamity.

Comment Re:Energy in? (Score 1) 142

Methanol is a well known starter compound for numerous synthetic pathways. I believe that in WWII it was used in Germany to power cars (though how often I don't know.)

I will agree that methanol would be a terrible jet fuel. It is not only low in energy density, it absorbs water like a sponge.

OTOH, many model aircraft used to use methanol for fuel, so it not totally unreasonable as a drone fuel.

Comment Re:Energy in? (Score 1) 142

In a different article (possibly about a different project) it was explicitly stated that the cost would currently be prohibitive, but that if oil ran out this could be a useful replacement.

I would be very surprised if the same caveat didn't apply to this project, presuming it's not the same project.
