Solar cells

In 1994, the U.S. Department of Energy announced production of solar panels giving nearly twice the efficiency of existing panels. Made by United Solar Systems of Troy, Mich., these amorphous silicon submodule (1 ft2) panels converted 10.2% of solar energy into electricity, as compared to 6% previously possible. This was possible by using new thin-film photovoltaic technology. The company has subsequently produced flexible solar shingles based on thin film photovoltaics that can permit the roofs of ordinary commercial and residential buildings to evolve from simply providing protection from the weather to becoming a source of much-needed electric power.

Going to Jamaica

A blonde gets on an airplane and sits down in the first class section. The stewardess tells her she must move to coach because she doesn't have a first class ticket. The blonde replies, "I'm blonde, I'm smart and I have a good job. I'm staying in first class until we reach Jamaica."

The stewardess gets the head stewardess who asks the woman to leave and she says, "I'm blonde, I'm smart, and I have a good job. I'm staying in first class until we reach Jamaica."

The stewardesses don't know what to do because they have to get the rest of the passengers seated to take off, so they get the copilot. The copilot goes up to the blonde and whispers in her ear. She immediately gets up and goes to her seat in the coach section. The head stewardess asks the copilot what he said to get her to move. The copilot replies, "I told her the front half of the airplane wasn't going to Jamaica."
