4k displays have been ready for prime time since the middle of last year, when Seiki released their 39 inch 4k tv for around $600. Its just the monitor driving circuitry has been slacking, and HDMI sucks, and they really should have had displayport and 60hz 4k on these panels since the middle of last year.

Oh how Id love to be there when you try a Oculus rift on for the first time. I dont think I have ever seen someone gain 12 pounds in 5 seconds from the the amount of their own words that they eat.

I see what you did there. That article was cleverly worded to imply that the convicted felons voted illegally, when in fact in the state of Minnesota, voting rights are restored to felons after they have served their probation.

The Challenger exploded because there was political pressure to include a rocket type on it whos failure mode is a explosion, to appease some senator and the solid rocket missile industry in his district..

ATK needs to stick to missiles and stop fucking up human spaceflight with its dangerous and uncontrollable firecrackers.

Why would you not have just one bigger engine powering a generator, and electric engines for the rotors and wheels?

The current administration has bloody well succeeded by waiting for commercial manned spaceflight to fill the role. And trust me, the Shuttle needed to die. It was a politically compromised design which led to it being expensive and unsafe. And if the current administration didnt sit on their hands, any crew carrying rocket they made would probably squeeze the likes of spacex out of contention. Not on price or efficiency mind you, but on government mandated usage by NASA. Much like the shuttle did for 30 years.

Yeah. They to have the right to censor their search results if they want to, being a private entity in the U.S. Though, if they don't make clear that they are censoring search results, then I imagine they open themselves up to being sued for false advertising if they claim to be a 'internet search engine'.

So thats a study that says that psychologists discriminate against colleagues with conservative views. I dont understand how that translates into "hatred against white Christian men". Seems they just dont like collegues with a political view that supports creationism over evolution in schools, ignorance of climate change research, and a general anti-science bent in their policies. Sounds like scientists being rational actors.

Am Australian compsci grad, can confirm. Its called HECS
P.S. you guys are getting fuuuuuucked.

It appears that MS disapproves of monopolies and lock-in in proprietary systems when there not the ones doing it. Worlds tiniest violin etc. etc.

well its true, i dont know the conversion from mah/g to kwh/kg here, but im going on that 1005mah/g figure stated, and its comparison to the 200mah/g for a current lithium ion battery. and im being conservative, using the 4x multiplier instead of 5x. And since they say charge-discharge cycles, i presume they measured the energy coming out of the battery.

well, you attached your name to some sarcastic pablum, and it still didnt make it worthwhile to say. But hey, at least now you know 1 more thing than you did before. have a gold star.

actually, i should probably lop off about 30km range to account for energy losses from the electric engine.

Lets see what the range on a typical light aircraft would be if you ripped out the full fuel tanks and gasoline engine and stuffed it with a equivalent power electric engine and these new batteries to the same weight. So it says it will store 4-5 times as much energy as todays best lithium-ion batteries. the best li-ion today is lithium cobalt, at about 165 wh/kg. So x4 of that is 660 wh/kg.

now, lets take a light plane for which I can find enough info to do this with, the jabiru j160D ok. so the fuel in it weighs (135L * 0.72kg/L) = 97.2kg. Now, the engine in it, the Jabiru 2200cc Aircraft Engine, weighs 62.8kg, and has a max power output of 60kw, and cruises at 75% power, so lets assume 50kw cruise power to account for takeoff and landing. So in total, engine and fuel weight 97.2 + 62.8 = 160kg

so lets rip that 160kg out and replace it with a EMRAX228 Brushless AC electric Motor with a 100kw power output and weighing in at 11.9kg, leaving us 148.1 kg worth of batteries, with a energy storage capacity of 148.1 * 0.66 = 97.746 kwh. so, at the cruise speed of 100knots = 185.2km/h, your looking at a range of (97.746kwh / 50kw) * 185.2km/h = 362km in about 2 hours.

The gasoline version can fly at the same speed for 8.5 hours. So, sure, the range is a quarter of the gasoline one, but you could ditch a passenger, chuck another 100kg of batteries in there and get that up to about 3.5 hours and 630km of range. Pretty damn good for a few dollars of electricity, negligible maintainence costs on a electric engine vs gasoline engine. sure as hell beats the $100+ youll pay for fuel alone for that same 3.5 hour trip.
