Comment Re:More batteries = more polution (Score 1) 118

Cobalt is not a heavy metal and is in fact essential for life and is a constituent of vitamin B12 and not all that toxic. While nickel can be toxic in some cases it is also plays an important role in plant and microorganism biology. Nickel also is not a heavy metal. Lithium also is also likely an essential trace element for mammals although they have not yet identified any physiological role. Aluminum also is not really toxic. If nickel were all that toxic then nobody would be using stainless steel cookware and silverware since it leaches into the food.

While nobody is suggesting that anyone eat the contents of lithium batteries, they are not considered toxic waste and can be disposed of in municipal wastes in most places, though it is more profitable to recycle them.

The batteries in my car contain lithium, aluminum and cobalt, no nickel. Also, lithium batteries are fully recyclable and there are already programs in place to recycle those batteries. Even the NiMH batteries used in some hybrids are fully recyclable and the batteries in my Prius had a refund for returning dead batteries. At least in terms of manufacturing the lithium batteries, Tesla is planning to fully power their manufacturing with solar power. Lithium batteries also only contain about 3% lithium.

That jives with my experience when I took a class that covered compression back in college. The professor, Glen Langdon held a bunch of patents at the time on arithmetic coding. Encoding efficiency could be improved by having it forget old data and making it more dynamic as I recall.

This information is often transmitted over EDID from the monitor to the host computer. Some graphics cards can use this information to automatically turn on and configure temporal dithering. The Linux nVidia driver can do this with the nvidia-settings utility. It will also report what the monitor is actually capable of.

The republican party is so worried about voter fraud that doesn't benefit them. There, fixed it for you. In virtually every case where they claim widespread fraud and the need for voter ID laws and other restrictions there has been no evidence to support that. In most cases it's voter fraud perpetrated by Republicans trying to limit access to voting to people who won't vote for them, i.e. the poor and elderly who may be less likely to vote for them and they often restrict the number of voting machines and how long the precincts are open in areas likely to not vote for them.

Also, water expands when it warms. The density of water is greatest at around 4C. Given how deep the ocean is, it doesn't take a lot of warming to raise the sea level noticeably. I read recently that around 1/3 of the sea level rise is due to melting mountain glaciers, 1/3 from increasing ocean temperature and 1/3 from Greenland ice melting. I suspect the amount of ice from Antarctica will increase significantly now that the ice shelves are breaking up which are holding back a lot of ice.

<sarcasm>It won't be a problem in North Carolina because they banned sea level rise planning. Texas and Florida should be fine too because you can't talk about climate change there or plan for it, so therefore it's not happening there. Clearly this so-called sea-level rise only happens in places where those pesky liberals who believe this so-called science live. Why, God will just protect these states just like he parted the Red Sea for Moses.</sarcasm>

It depends on where you are within the state. In the major population centers it's fairly blue. In the rest of the state it's fairly red.

With the recent voter initiatives that largely did away with gerrymandering and made it so that the two biggest vote getters run in the main election the state government has become far more centrist. In a recent election in my district for the US house of representatives it was between a very left-wing democrat against a centrist moderate democrat. The centrist beat out the long-term left-wing democrat. In other districts there were two republicans running against each other and often the more moderate candidate won. The system tends to favor moderates in both parties over the extreme left or right. The endless bickering and road blocks have largely gone away and the state finally has a budget surplus and rainy day fund due in large part to a spendthrift democrat governor. The republican obstructionism has largely gone away and the two sides are actually working together *gasp*. That's not to say things are perfect, but it's far better than it was when everything was held hostage by the far right. In some way our governor is too much of a spendthrift. Our roads are among the worst in the nation and we need to spend some serious dough to repair them but he's being quite reluctant to raise the gasoline tax or pay for it despite even the very conservative Chamber of Commerce asking for this.

Tesla supports plugging into a standard NEMA 14-50 50A plug. This plug is common for RV parks and for large appliances like electric stoves. The tesla cable that comes with the car contains the GFCI and other safety circuitry in it. The Tesla wall charger includes the cable and does not provide a plug on the wall.

The problem was that the fuses were too sensitive and tended to blow under the designed load. It was the fault of putting too small of a fuse in the circuit, like putting an 80A fuse in an 80A continuous circuit. The replacement fuses are the same as the ones in all of the shipping Tesla charging adapters which are UL approved. All of the wiring and whatnot is designed for 100A with a 100A breaker.

Normally you should not run a continuous load over 80% of what a circuit is rated at. So if there's a 100A breaker you can draw a peak current of 100A but continuous load should not exceed 80A.

It also helps advertise the Airbnb location if it's like other places that install Tesla chargers. Tesla shows hotels that have installed them on their charging map along with their superchargers. As a Tesla owner it certainly makes locations that have installed it a lot more desireable than places without charging support, especially if it can handle at least 40A. Many EV chargers are limited to quite a bit less, i.e. 16A for the cheap ones.
