There's a heat pump out there that has a wire running through the outdoor coils but electrically insulated from the actual coil. The wire connects to a circuit that generates high voltage, very high frequency AC (about 800v at 915MHz). When power is applied, the frost in the gap acts as a very lossy dielectric, heating up very fast and vaporizing almost instantly. The resulting shock wave blows the rest of the frost out of the coils.
If America manages to eliminate obesity, we would save as much fuel as if every American were to stop driving for three days every year. To be slender like Tiffany Yep is to be a real hypermiler...

Allie Moore and I have a combined carbon footprint much smaller than that of one average American...
