Unlimited mile warranty for Tesla Model S 85 kWh

Credit: Tesla/Treehugger

Tesla warrants its battery pack for 8 years & unlimited distance. On the other hand, the drivetrain is covered by a four-year, 50,000-mile, limited warranty.

Until now.

In a post on the Tesla blog, CEO Elon Musk has extended the warranty on the drivetrain to match that on the battery pack. Hence the, "Infinite Mile Warranty", title on the Tesla blog post at:

OM Audio levitating Bluetooth speaker

Credit: Engadget

It really is a magnetically levitating Bluetooth speaker. Battery power for the speaker itself, which can operate without the base. AC adapter for the base, which provides the magnetic levitation magic.

Manufacturer claims that the levitation is not just a gimmick — by eliminating the damping effect of contact with other objects, better sound is produced with a lower power requirement. This may contribute to the claimed battery life of 15 hours.

1K (1024), centimeter size robots, each capable of following some simple programming rules, & communicating with the others by infrared, can co-operate to form complex shapes.

Tiny, reversible USB Type-C connector finalized

USB connectors have been getting smaller & smaller. First step down was mini USB, followed, more recently, by micro USB.

Can you relate to the graphic above? mini USB was was arguably an improvement, but I have difficulty reading the orientation of micro USB in poor light. Well, that problem is about to be solved. USB connectors are about to have a new iteration: USB Type-C. It will be about the same size as micro USB, but will be reversible, & compatible with USB 3.1, which will support data transfer speeds up to 10 gigabits per second (i.e. double the data rate of USB 3.0) & up up to 100 Watts of power.

Intention is that it will replace all previous USB plug/socket standards, on all types of devices. That promises the elimination of a lot of adapter cables. My guess, though, is that the conversion process will take so long that a new connector standard will have been defined before it is complete.

Big time (video)

It's one metre long, just 4 mm thick & weighs less than 1.8 kilogrammes.

An ultra-energy-efficient E Ink* display means it runs for approximately one year on a single button battery.

Self leveling magnetic wall mount.

Tells the time.

And looks fabulous doing it.

The catch? $499.

Vitamin D — more important than we thought

Vitamin D — traditionally, it has been associated with the body's use of calcium. Deficiency has been associated with rickets. More recent research is showing that deficiency can increase the risk of such such a diverse range of maladies as diabetes, dementia, schizophrenia & falls in the elderly.

In some ways, the ability of the skin to produce vitamin D when exposed to sunlight provides a simple solution. Except, sunlight exposure carries with it elevated risk of skin cancer. Sunscreen provides a level of protection against sunburn & skin cancer, but also prevents production of vitamin D. Dark skin is protective against skin cancer, but also reduces vitamin D production. At high latitudes, a dark skin may make it difficult or impossible to get enough sunlight exposure.

In the light of the above, dietary sources & supplements become more attractive. Relatively few foods contain vitamin D, but fatty fish (such as salmon & tuna) & fish liver oils are among the best sources. Lesser sources are beef liver, cheese, & egg yolks.
