Travelling interstellar distances requires cheap energy like fusion. If we canmaster fusion energy we may as well remain on earth because we will not need fossil fuels, convert sea water into fresh water and grow food with controlable costs.

Car Glass Rules Could Impair Cell, GPS and Radio Signals In CA 762

Posted by timothy
from the micromicromicro-managing dept.
An anonymous reader writes "The California Air Resources Board (CARB) just passed a new regulation that requires glazed glass in automobiles that is supposed to reduce the need to use air conditioning. The catch is that the same properties that block electromagnetic sunlight radiation also block lower frequency electromagnetic radio waves. That means radios, satellite radios, GPS, garage door openers, and cell phones will be severely degraded. Even more surprising is that it requires this glass even for jeeps that have soft covers, plastic windows, and no air conditioning.'"
