Tesla Tech

The MIT Technology Review has a look under the hood of the electric Tesla Roadster.

Some the interesting things found there include the alternating-current induction motor and the lithium-ion battery cells.

The motor is of the type advocated in the late 19th century by Nikola Tesla, and has several mechanical advantages over a DC motor.  The lithium-ion battery cells give more power for the volume than  nickel-metal hydride batteries.  The nickel-metal hydrides are what are typically used in gas-electric hybrids, such as the Pious.

Unlike the gas-electric hybrids, the Tesla roadster can go from 0-60 mph in 4 seconds, without putting a dime the pocket of Middle Eastern oil tyrants or Central American Socialists.

No Bluetooth support in Android 1.0

According to the Android Developers Blog, Bluetooth support has been dropped from the upcoming Android 1.0 release.

The reason is that we plain ran out of time. The Android Bluetooth API was pretty far along, but needs some clean-up before we can commit to it for the SDK. Keep in mind that putting it in the 1.0 SDK would have locked us into that API for years to come.

The honesty is refreshing, but that is a major chunk of basic functionality missing.

Keep in mind, that Android plans on doing a lot more with Bluetooth than supporting wireless headsets. So I’m expecting a 1.1 release to follow up pretty quick with Bluetooth and GTalk functionality.
