How Argonne National Lab Will Make Electric Cars Cheaper

holmstar Re:I'll believe it.... (143 comments)

The model 3 will be marketed against things like the BMW 3-series and Audi A4, so we're still talking about luxury cars.

Ebola Quarantine Center In Liberia Looted

holmstar Re:Truly sad (359 comments)

That HIV has not acquired other methods of transmission does not guarantee that Ebola will not. Ebola has infected far fewer people, and we simply don't know the likelihood of it doing so.

Ebola Quarantine Center In Liberia Looted

holmstar Re:Truly sad (359 comments)

Ebola is not as infectious as the flu.

Yet.

So, right now there's at least few thousand people carrying the virus. At least a few of them probably have other cold/flu viruses in their systems. If both Ebola and flu infect the same cell, they can exchange genetic information, potentially resulting in a much more easily transmitted strain of Ebola. The more people that are infected, the greater the chance such genetic exchange could occur. It wouldn't take much for Ebola to become a first world threat.

How a Solar Storm Two Years Ago Nearly Caused a Catastrophe On Earth

holmstar Re:Low probability of getting hit by CME (212 comments)

The three times in 200 years is for really large CMEs. Smaller ones hit the earth much more frequently.

How a Solar Storm Two Years Ago Nearly Caused a Catastrophe On Earth

holmstar Re:news for nerds in the speculative future(or pas (212 comments)

Or there could be a nearby gamma ray burst.

There isn't much point in worrying about this. About the only people that would be spared on the side of the earth that was exposed would be people that were already underground/under water at the time. How far underground/under water would depend on the intensity of the gamma rays. Even if we detected a burst of neutrinos to alert us that something was coming, it wouldn't be enough warning for anyone to take shelter that wasn't already there. I guess if you really wanted to be safe you could live a few hundred feet down in an old mine, but that would rather suck.

Half of Germany's Power Supplied By Solar, Briefly

holmstar Re:...but they still have all the disadvantages (461 comments)

If you were directly exposed to cobalt 60 (ex: holding a lump of it in your hand) you'd probably be in pretty rough shape, though that isn't used for nuclear power.

Aliens and the Fermi Paradox

Crabs certainly did. The mudskippers could, given more time. I'm not sure what would convince you. You seem to have already made up your mind.

Elon Musk's Solar City Is Ramping Up Solar Panel Production

holmstar Re:Tie this in with the battery tech from Tesla... (262 comments)

They never said that they made solar panels (though this purchase changes that). They are an installer and financier of solar panel installations. Part of the reason they are moving into solar cell and panel manufacturing is so that they can assure access to high efficiency panels at a reasonable price. They have stated that this is necessary for the business to be viable after solar incentive programs wind down. Regarding obsolete panels, I wouldn't be surprised if solar city has plans for upgrading existing clients and re-purposing old panels as technology improves. (We can now provide 75% or your electrical usage instead of the original capacity of 50%!). It would be a win-win, assuming that they have a use for the older panels.

Aliens and the Fermi Paradox

holmstar Re:Progenitors? (686 comments)

Climate change is certainly a problem, but it's far from eliminating human life on planet Earth. I'd be more worried about an engineered pathogen.

Aliens and the Fermi Paradox

holmstar Re:Progenitors? (686 comments)

Less significant (but not evidenced in the DNA or fossil evidence) would be multiple independent species making the transition from sea to land

We don't need fossil evidence. There are species of crabs that live on land. Mud-skippers live mainly in the water, but could easily evolve to land based animals.

We can't rule out a great number of things. That doesn't mean that they have any credence.

Aliens and the Fermi Paradox

The only event of that magnitude that we have evidence of created the moon.

So what is to say that there wasn't a technical civilization on earth before the creation of the moon?

Group Demonstrates 3,000 Km Electric Car Battery

holmstar Re:Only 1600km, not 3000 (363 comments)

Sorry, that should have read:

No, the 3000km is assuming that you are using the aluminum air battery in addition to the normal lithium battery."

No, the 3000km is assuming that you are using the lithium battery in addition to the normal lithium battery. The aluminum air battery is only to extend range by a total of 1600km. the other 1400 is from the lithium battery that you are charging each day.

The Brakes That Stop a 1,000 MPH Bloodhound SSC

holmstar Re:Stronger? (262 comments)

Also, we're not talking about 1000 to 0, there are parachutes to do most of the deceleration. The "regenerative" style braking would be for something like 200-0.

The Brakes That Stop a 1,000 MPH Bloodhound SSC

holmstar Re:Stronger? (262 comments)

The "car" is traveling at high speed. It should be relatively simple to divert some of that fast moving air through the resistive coil to cool it. Probably a LOT easier than trying to dissipate the same amount of heat from the brake disks.

The Brakes That Stop a 1,000 MPH Bloodhound SSC

holmstar Re:Steel is stronger than carbon in many instances (262 comments)

In order for friction to destroy steel, it needs to actually wear it away one particle at a time. Being so much heavier/denser, there are that many more particles to wear away.

Or, you know, heat it up so much that it starts to melt. That's a real possibility for this application. A previous poster suggested rheostatic brakes (basically regenerative braking, where the electricity is dumped into a big resistor instead of being stored for later use). It would add weight and complexity, but if regular brake disks can't dissipate the energy fast enough, then something like that might be necessary.

Why not just dump the electricity into a resistive coil? No need to store it.

US Should Use Trampolines To Get Astronauts To the ISS Suggests Russian Official

holmstar Re:SpaceX isn't ready (272 comments)

Just don't spend a single fucking dime of my tax dollars

From your other post:

But if you want to keep on being a typical arrogant American cocksucker, who thinks your shit doesn't stink and everything with a fucking American flag on it must be the GREATEST GODDAMNED THING IN THE FUCKING WORLD, then be my guest. Just don't be surprised when everyone who isn't American spits on you when they find out where you're from.

I guess that makes you a "typical arrogant American cocksucker"?

Bucky balls nearly double lifespan in rats

holmstar holmstar writes  |  more than 2 years ago

holmstar (1388267) writes "Researchers at Université Paris Sud in France have discovered that bucky balls mixed with olive oil, when consumed along with a normal diet, extend the lifespan of rats from 22 months to 42 months. Olive oil without bucky balls extended life span only to 26 months."
