Comment Cool, but how useful? (Score 4, Insightful) 222

Covering all of the car is nice, and 1K+ miles a year is also nice. Is it going to stop you from charging it? No. There isn't enough sun per sq. in. to cover usage for drivers between trips, in cities with large buildings and skyscrapers, you limit the amount of sunlight it can get during the day, in winter it is even worse up north.

Depending on the area, there will be no ROI for using it vs regular paint.

Still cool tech, and I would be much more interested in using it on housing, siding and metal roofs, carports and sheds. This would be a nice addition to solar for the home, or a standard feature for new builds.

Comment So, the same thing Chips do now? (Score 1) 124

Modern chips already do this, it is called out of order threading. Intel and AMD both do this, what makes this different?
At the extreme end of this, the Mill design does this with each instruction packing up to 32 commands. What is the thing this is doing exactly? Is it able to address all the cores at once, maybe? Currently this is done on a per core basis, and multiple instructions have been in Intel chips since the Pentium Pro days at least. If they could somehow do this across all the cores on a chip, I could see this might work with current designs.

Or is it taking current code and turning it all into SIMD maximizing usage? I really don't know what they are doing here that is so special.

Comment I missed the point where they explain... (Score 4, Insightful) 104

I missed the point where they explain that the newer kernels aren't around enough for the bugs to be encountered, so while it looks like the bugs are with those older kernels, the newer kernels have them and more that are just not found, because they aren't in as much use.

I am trying to decide which is funnier, this or grown men and women responding to someone not showing up by banning them from showing up.

Its like someone sat down, then someone else pointed at them and said sit expecting everyone to believe they have the power in that situation.

I would be if Amazon came calling, this will be forgotten in less than a second.

The examples I gave, in case it wasn't clear enough, was of an EV not starting because the batteries were too cold, not that you ran out of energy. You will damage your EV if you try to charge the batteries when they are out of their safe zone, if the car doesn't have built in protection.

Now, are you saying you can run the heater from the other car to heat up the batteries? How long will that take? Even if you just have to raise the temp by 10 degrees, you aren't doing that in 10 mins.

Comment That is NOT the reason people are paying attention (Score 1, Informative) 216

You have a very different issue with an electric car. For a gas car in the cold, if the battery dies, you can jump the vehicle and the vehicle will run.

You can't do that with an electric car. You have to get the batteries up to temp before working which may take a while if you can manage it that day. It is still an inconvenience for the gas vehicle, but you can leave with a few minutes of finding a jump or a starter.

The electric vehicle is much more of an inconvenience and potentially more fatal. Temps that stop electric vehicles also happen to be cold enough to be deadly to humans, so if you are out in the middle of nowhere, you could freeze to death before you get help. Now, that may happen with the gas car as well, but you have better odds of finding a way to get a jump than waiting for the car to heat up to let the batteries work.

Now, this doesn't mean you can't design a better experience for the electric car. Better insulation could be used and an emergency battery of a different type that has a lower operating temperature to heat the batteries are some first glance solutions that make it less likely to happen.
