I've done a lot of roofing in my life, one type being a rubber roll that gets melted down with a propane torch for flat roofs. An aluminum coating in a can needs to be applied to the rubber roof in order to reflect the ultra-violet rays of the Sun. If this special coating isn't applied, the rubber rots away within 5 years. Reapplying this silver coating every 5 years can almost indefinitely extend the life of the rubber roof. Does this material do this also?
If it's over 8 years old, you may have to replace the battery. How much will that cost? From Quora, link below...
It costs about $225 to replace a Tesla battery. I assume you mean the 12v battery that powers things such as the electronics in the cabin and other 12v devices.
If you mean the main battery, that’s a lot harder to say because it’s not something that people need to do. The batteries come with an eight year warranty, mostly with unlimited miles, and Tesla will repair a defective battery pack for free. Virtually all of them are still under warranty.
Tesla’s batteries lose range very slowly, and even on a car that’s a decade or two old, it’s not likely that a person would replace a battery to increase range. The average US driver travels under 40 miles per day, and most Tesla owners plug in at night to charge at home. For day to day use, owners would never see a difference.
Even for trips of hundreds of miles, there’s a good chance that somebody with a 15 year old Tesla will be able to make the trip with the same number of charging stops as were required when the car was new. But if it turns out that it takes an extra stop each way, then it’s still unlikely that people would replace the battery. People who take an annual road trip or two who might save a couple of hours on each one at the most aren’t going to want to spend thousands of dollars on a new battery. The book value on a car that old might be only a few thousand dollars. If $2000 is out of the question to save two hours a year, then a more realistic price would be even more out of the question.
If you buy a Tesla, it’s fair to assume that the main battery will never need to be changed.
Lets just pretend labor is free, and you purchased a Model S P100D in 2016. In 2016 the cost per kWh was 227. The 100kWh battery would have cost $27,700. That same battery if Elon is the believed will cost Tesla $100 per kWh by the end of 2018, for a total battery replacement cost of $10,000. Of course that car is still under under warranty until 2024 so a replacement would not be of concern the current owner.

Batteries in a hybrid vehicle can cost multiple thousands - so much in fact, that they are in effect non replaceable - the car costs less!
I’m not sure if there is a separate 12v battery for the car (as ALL the batteries have the same nominal voltage.)

Fair enough. I suppose savvy investors know when to get out and when to keep investing. If it turns out to be a case of another startup gone south or a wise business decision, time will tell, I suppose. (munches popcorn)
Everything that I've heard is that Uber losing $1.50 for every $2.50 that they earn. Supposedly, someone correct me if I'm wrong, Uber is going to run out of money by the end of the year if they don't get another infusion of investor cash. Self-driving cars are still probably 10 years away, sounds to me like Uber is going to be long gone by then
Agreed, in my day if I wanted to 'get lost', I could do it. Just walk or drive somewhere and I couldn't be found unless I wanted to be found. The way tech has ballooned into "no one has a private life" anymore is very strange and alien to me. Humans are adaptable I know, but this life is changing fast. I do feel bad for the newer generations who'll never know that feeling of full privacy.

The planet will be here for a long, long, LONG time after we’re gone, and it will heal itself, it will cleanse itself, ’cause that’s what it does. It’s a self-correcting system.

And if it’s true that plastic is not degradable, well, the planet will simply incorporate plastic into a new paradigm: the earth plus plastic. The earth doesn’t share our prejudice toward plastic. Plastic came out of the earth. The earth probably sees plastic as just another one of its children. Could be the only reason the earth allowed us to be spawned from it in the first place. It wanted plastic for itself. Didn’t know how to make it. Needed us. Could be the answer to our age-old egocentric philosophical question, “Why are we here?”

I just met a 23 year old guy who's happy with his iPhone4. It does what he wants, texts & phone calls, I told him stay with it, just get a new battery for it, cheap and so easy to do that he could do the swapout himself with a soldering iron. Some people just want what works.
Just to justify more expensive crap that is not needed?? WTF? Direct connections have worked for over 80 years, now some tech companies insist we all are 'bettered' with expensive must have peripherals that are inferior, more costly, and last about 6 hours while depleting the sources battery too? Bluetooth has always been a downgrade in listening quality, and also a vector attack. Who wants this, except for 3 letter agencies to gain access to our devices and ignorant young fools who do not realize the implications? Tech was supposed to make our lives better. Instead it's used to invade our privacy.
My lifes warranty is about up anyway, I do weep for the future generations. They have no idea what they're giving up in exchange for the 'cool factor'.

It's been many long days since NASA's Mars Opportunity rover last phoned home.
The rover has been quiet since June 10, when a massive planet-covering dust storm cut off its access to solar power. The storm is subsiding and now NASA is playing a tense waiting game to see if the vehicle will come out alive and rolling.
Opportunity is nearly 15 years old and has long outlived its initial three-month mission plan while continuing to deliver science observations back to Earth.
While the extended silence is worrisome, NASA says "there's reason to be optimistic." Studies of the rover's batteries before the storm show they were in good health and likely won't suffer much degradation during its time in the dust storm shadows. The temperatures in its location also mean the rover should have stayed warm enough to make it through the stretch of darkness.
NASA is reaching out to the rover in hopes of hearing back if and when it awakens. The Opportunity team pings the machine several times each week and listens for a response. NASA is also listening for radio signals from Mars that could be coming from the rover.
NASA warns there could be a long lag between the first signs of the rover's awakening and any further signals. "It's like a patient coming out of a coma," NASA says. "It takes time to fully recover."
There's a plan of action in place should the rover get back in touch. Opportunity's team will strive to learn more about the state of the rover, its batteries, solar cells and temperature. The rover's clock may need to be reset, and mission control will ask it to image itself to look for dust contamination.
Now here's the potentially scarier part. "Even if engineers hear back from Opportunity, there's a real possibility the rover won't be the same," NASA says. The dust storm could have a negative impact on the rover's batteries, which could put a crimp in its ability to heat itself during the frigid Mars winter.
Opportunity's science team is keeping the world informed through a series of mission status updates. Here's the latest: "The science team does not expect to hear anything from Opportunity until the atmospheric opacity over the rover site clears further." And so we wait.
We can barely predict the weather on Earth. The dust storm is supposedly subsiding. Here's the best I found...
The Massive Mars Dust Storm Is Starting to Die Down
The dust is finally beginning to clear on Mars, but it'll probably still be a while before NASA's sidelined Opportunity rover can phone home.
A global dust storm has enshrouded Mars for more than a month, plunging the planet's surface into perpetual darkness. That's complicated life significantly for the solar-powered Opportunity, which has apparently put itself into a sort of hibernation; the rover hasn't contacted its controllers since June 10.
A long-awaited dawn seems to be on the horizon, however.
"It's the beginning of the end for the planet-encircling dust storm on Mars," NASA officials wrote in an Opportunity mission update yesterday (July 26).
Scientists studying the storm "say that, as of Monday, July 23, more dust is falling out than is being raised into the planet's thin air," agency officials added. "That means the event has reached its decay phase, when dust-raising occurs in ever smaller areas, while others stop raising dust altogether."
Other data points support this conclusion. For example, measurements by NASA's Mars Reconnaissance Orbiter show that temperatures in the middle atmosphere have stopped rising, indicating less absorption of solar heat by dust particles.
In addition, NASA's Curiosity rover — which is nuclear-powered and can therefore work through the storm — has observed a decline in overhead dust at its location, the 96-mile-wide (154 kilometers) Gale Crater, agency officials said.
Some Martian landforms previously hidden beneath the dust can now be spotted from orbit again, they added, and may even be visible using Earth-based telescopes by early next week, when Mars will make its closest approach to our planet since 2003.
From the onset of Bluetoooth it has never been secure, even when 'off'. It has always been an attack vector to gain access to a smart/dumb phone. NSA crap. Welcome to this modern world.:/
(Are wireless headphones even safe?) No, for security they are not. They were never meant to be secure by design from the get go.
Security company Armis has found a collection of eight exploits, collectively called BlueBorne, that can allow an attacker access to your phone without touching it. The attack can allow access to computers and phones, as well as IoT devices.
“Armis believes many more vulnerabilities await discovery in the various platforms using Bluetooth. These vulnerabilities are fully operational, and can be successfully exploited, as demonstrated in our research. The BlueBorne attack vector can be used to conduct a large range of offenses, including remote code execution as well as Man-in-The-Middle attacks.
“BlueBorne affects pretty much every device we use. Turns that Bluetooth into a rotten black one. Don’t be surprised if you have to go see your security dentist on this one,” said Ralph Echemendia, CEO of Seguru.
As you can see from this video, the vector allows the hacker to identify a device, connect to it via Bluetooth, and then begin controlling the screen and apps. It’s not completely secretive, however, because in activating the exploits you “wake up” the device.
The complex vector begins by finding a device to hack. This includes forcing the device to give up information about itself and then, ultimately, release keys and passwords “in an attack that very much resembles heartbleed,” the exploit that forced many web servers to display passwords and other keys remotely.
The next step is a set of code executions that allows for full control of the device. “This vulnerability resides in the Bluetooth Network Encapsulation Protocol (BNEP) service, which enables internet sharing over a Bluetooth connection (tethering). Due to a flaw in the BNEP service, a hacker can trigger a surgical memory corruption, which is easy to exploit and enables him to run code on the device, effectively granting him complete control,” write the researchers.
Finally, when the hacker has access they are able to begin streaming data from the device in a “man-in-the-middle” attack. “The vulnerability resides in the PAN profile of the Bluetooth stack, and enables the attacker to create a malicious network interface on the victim’s device, re-configure IP routing and force the device to transmit all communication through the malicious network interface. This attack does not require any user interaction, authentication or pairing, making it practically invisible.”
Windows and iOS phones are protected and Google users are receiving a patch today. Other devices running older versions of Android and Linux could be vulnerable.
How do you stay safe? Keep all of your devices updated regularly and be wary of older IoT devices. In most cases the problems associated with BlueBorne vectors should be patched by major players in the electronics space but less popular devices could still be vulnerable to attack.
“New solutions are needed to address the new airborne attack vector, especially those that make air gapping irrelevant. Additionally, there will need to be more attention and research as new protocols are using for consumers and businesses alike. With the large number of desktop, mobile, and IoT devices only increasing, it is critical we can ensure these types of vulnerabilities are not exploited,” wrote Armis.
My moto e4 has a radio app that works, but not with earbuds. Not a problem since I use wired headphones that serves as an antenna wire. I do weep for the future generations who are getting trained to accept the new way of paying extra for everything.
I've owned Koss over ear headphones for over 29 years. No tiny batteries that wear out within a year, no connection problems with bluetooth (which is an attack vector, look up "bluetooth hacks".). Call me an old fart, GetOffMyLawn type of guy, I stick with what works. Screw these companies who keep trying to sell us the new tech that needs to be replaced every year or so. Easy to lose earbuds, my Koss headphones sound great and I always know where they are. So there.
