Talking Frog

A guy is 86 years old and loves to fish. He was sitting in his boat the other day when he heard a voice say,
"Pick me up."
He looked around and couldn't see any one. He thought he was dreaming when he heard the voice say again,
"Pick me up." He looked in the water and there, floating on the top was a frog.
The man said, "Are you talking to me?"
The frog said, "Yes, I'm talking to you. Pick me up.
Then, kiss me and I'll turn into the most beautiful woman you have ever seen.
I'll make sure that all your friends are envious and jealous because you will have me as your bride."
The man looked at the frog for a short time, reached over, picked it up carefully, and placed it in his front breast pocket.
Then the frog said, "What, are you nuts? Didn't you hear what I said?
I said kiss me and I will be your beautiful bride."
He opened his pocket, looked at the frog and said,
"Nah, at my age I'd rather have a talking frog."

Solar power plant

In 1980, the first U.S. government solar power plant was dedicated. It is sited in the sunny desert at Natural Bridge National Monument, Utah, and at the time the world's largest. An array of over 250,000 solar cells arranged in 12 long rows provides up to 50 kilowatts of power. The plant provides elecricity for the park's visitor center, staff residences, maintenance facilities and water sanitation system, which were otherwise 38 miles away from the nearest alternate power line. The power plant was part of a joint venture of MIT's Lincoln Laboratory and the Dept. of Energy. Huge batteries provide power at night and on cloudy days. A backup diesel generator automatically takes over if the batteries are drained too low. Its use is far less than the one the solar panels replaced, saving noise, exhaust pollution and fuel cost.«
