This battery has lower energy density(20Whr/kg) than your current SLA's at (50Whr/kg)..ref

The claim of room temperature processing is also somewhat misleading.. They included an annealing step at 350C under argon atmosphere for 1 hr for processing the iron oxide nanorods.

No mention of charge efficiency, should be bettery than the 60 to 70% for SLA's, (note: Lithium ion charge efff is ~95-98%)..

Traveling through through space containing the typical atom of interstellar hydrogen per cm^3 at relativistic speeds(0.95C) would result in instant death.

Even if you were frozen solid, the ice would melt and water around/inside you would boil. Not to mention nearly every chemical bond in your body would be broken. At lower sub light speeds. 0.5C one would still have to deal with many years of accumulated cosmic radiation damage once you were taken out stasis(You're dead).

Short of some sort of wormhole/warp discovery, travel between stars at best something would require storing memory and conscious digitally, (constantly self repair & correcting) then manufacturing a suitable body at the destination. Or just remain as a machine conscientious, since biological organisms won't survive a intersteller trip intact.

By the time one reaches anywhere near the maximum solar usage threshold, attempting to use any combination of fossil/nuclear energy would burn the planet to a crisp.

FF/nuclear Waste heat(50-70%) to match solar flux levels would make AGW(Added CO2 = + 1%), look like a picnic.
Yes, their is energy consumption limit/(ultimately converted to heat) at which humanity must leave the planet.

Even on a mostly cloudy day my solar panels produce about a quarter(1/4) of their normal output. Enough to run the house loads (frig, freezer, PC, lights, tv, etc).

I cut household electricity CO2 footprint by another metric ton this year. Soon.my PV will be on a solar tracker, that should reduce non-food related CO2 footprint to near zero.. I will be the first person in my republican dominated city to achieve a near zero carbon footprint house. Someone's got to break the mold, and leave FF behind, I hope many others will follow.

P.S. My residence along with the city and most of South Florida will be underwater one hundred years from now. (unstoppable sea level increase). You would think they would sit up and take notice as the bi-annual king tides are now flooding the streets in front of million$+ houses, might give them a clue. But no, blinders on, full speed ahead, buy that big ass SUV, Yacht, waste energy, burn those fossil fuels unending (And seal a watery fate.)

Pocket Dialing, how many times have you pocket dialed, or received a pocket dial? Blame it all on the slide to unlock feature.

After my pocket dialing episode ~5 years ago, I switched to pattern unlock on my Andriod phone (NO more packet dials). It's also helped a couple of times retrieving my misplaced phone. Definiitly reduces desiriblity for the finder to keep a lost or misplaced phone.

Survive Nuclear war.. I don't thinbk so..

While detonating a few Gigatons worth of nuclear weapons over various targets would be bad.

Far worse would be the hundreed's of Giga ton's of fission byproducts released into the biosphere from destoryed/damaged/unattended nuclear reactors and spent fuel pools around world. At best average human life expetancy would drop into the low to mid 20's

Wayyy more than a HUNDRED years!!!!

The second sentence should be, "He taught them how to "...

30 years ago, was a different age of computing where the computer industry was full of very talented people trained in other fields.. We don't have that anymore, Microsoft, Intel, HP, etc, laid them all off, (older employees), and would never hire someone that hasn't been through their indoctrination regime.

The last time Microsoft had anyone qualified in the fields organic chemistry/biology working with on a M$/IBM project was around thirty years ago. He though them how to implement a superior testing regime for their Operating systems using laboratory/statistical/analysis techniques.

I really doubt Microsoft is wise enough to employ those type of cross trained experts anymore.

As for curing cancer in ten years, they have a better chance of initiating some form of Apocalypse, ( PC OS mono culture, with Billions of PC's being taken over), triggering WWIII, release of a bio-weapon, nano-replicators, etc., rather than curing cancer. With everybody dead, cancer in humans is definitely cured, ergo Microsoft get's the credit posthumously.

In the first sentence of the first linked article it mentions Samsung phones are infected with this backdoor, I'm asking why would that be?

I've got two rooted SAMSUNG galaxy class phones. Neither of them has this app installed. Why would Samsung allow a Rival to install modules on the phones they manufacturer, sell, support, and warranty?

One should not forget that Ireland received a large banking Bailout(61B euro, 25% NPL's) from the ECB and IMF not too long ago. Ergo, it is illegal to make sweet heart deals with 3rd parties(Apple) allowing them to avoid paying taxes incurred in other member states(EU).

I.E. You can't be just a little bit pregnant, (member of EU). Either your all in, or not, that was the choice Britain just made.

Inside LOX tank their are anti slosh baffles made out aluminum which are welded to the inside of the tank. During fueling those welds will be under thermal stress, if one of the welds gave out it would expose Al metal to the LOX then BOOM. The tank material itself reacted with the Pure O2.

It's the nature of the beast when dealing with LOX tanks. 1st)It would be wise to let the tank sit with a pressurized with a couple of psi of O2 for several weeks building up a thicker ceramic AlO2 layer. 2nd) implement a staged cool down procedure before filling tank with cryonic oxygen to reduce stress on welds..

Our Ohio class boomer fleet uses Magneto Optical Disks for targeting, but that was some time ago.. They may have upgraded since. N Korea goal is to detonate an EMP burst over the USA from orbit. The USA will retaliate against N Korea city''s & military and EMP their supporters China+Russia in kind, leaving neither side with a real advantage.
