Wait, meteors that hit the ground are cold to the touch? That doesn't make sense - they enter the atmosphere, and as we know objects entering the atmosphere travel so fast that they get hot...real hot...so hot that our space ships need to have heat shields to keep the folks inside from getting burnt to a crisp...which makes it not cold to the touch. So when the rock hits the ground why would it become cold all of a sudden? Maybe if it sat around in cold climate for a while but after touch-down it should be very hot.
There is a difference between a space vehicle, which is as light as possible and hollow, and a meteor which is solid rock (or, much more rarely, metal). The heat shield is thin and light (comparatively speaking) but keeps everything inside quite cool despite a very lengthy heating period (due to the shallow re-entry angle of manned vehicles, and most unmanned ones, which cannot stand severe deceleration forces).
A meteor (one meter across or less) typically enters at a steep angle, decelerates rapidly (in several seconds) at a few hundred Gs, and becomes a rock falling under the influence of gravity through the lower atmosphere same as any other rock of similar size dropped from a high-altitude airplane.
For those several seconds a very small part of the rock gets very hot indeed - a thin layer vaporizes, and a thin layer melts. But it is physically impossible for the bulk of the rock to get significantly heated in the few seconds of re-entry, conduction is far too slow. During the longer part of its descent (when it is simply falling through the air for a few tens of seconds), there is enough time for the thin molten surface layer to get cooled down to near normal temperatures by the cold airflow. Then when it hits the ground within a minute or two there is enough time for the icy cold interior to cool down the surface to frigid temperatures.
The special effect of burning a pyrotechnic in the crater was perfect to take in the ignorant, but is laughable to anyone knowing something about meteors.
As much as I hate to say it.... because twitter has a very open API and there are a ton of programs for any OS that interface with it.
I'm setting up some home automation. Nothing fancy, just garage door open/closed. Temperature in a few rooms. HVAC status.
I could write a ton of stuff from scratch for reporting & control... or just make a private twitter account "my_house" and subscribe to it. I can get a text message every X minutes with the temp. A text message when the garage door cycles. I can easily text back commands.
@my_house 'heat on 75F'.
They've already taken care of the interface between phones, e-mail, blackberries, iphones, etc.
With this tool I can have a cheap display at my desk at work or even in my own house for the temperature, HVAC status, etc.
