Car Forum / Driving, Maintenance, Tuning / RVs / November 2007I've heard
I have a friend who has lots of big solar panels on his boat. He uses floodlights powered by the solar panels at night to keep them generating electricity all night long. He uses the extra electricity to run his laptop and watches DVD's. Never runs out of electricity even on a cloudy day because of the floodlights.

The panels don't approach 100% efficiency, and neither do the spotlights or batteries. You've described a "perpetual motion" device, and it isn't so. > >I have a friend who has lots of big solar panels on his boat.

A guy was pulling a small, but useable amount of electricity off of his solar panels during the night. Turns out he was parked right on top of an old radium mill site, complete with tailings and the radioactivity striking the panels generated electricity. Is the boat located anywhere in the Bermuda triangle? Steve >> I have a friend who has lots of big solar panels on his boat.

Solar panels respond to gamma rays: http://adsabs.harvard.edu/abs/1999SPIE.3698..920H http://www.osti.gov/energycitations/product.biblio.jsp?osti_id=4166955 http://www.health-physics.com/pt/re/healthphys/abstract.00004032-196706000-00005 .htm;jsessionid=HGGTtj2s6yfvysTSp1b3pN9jM5nlp3SRv43vZQMKG0qrDx34syPP!391776677!1 81195629!8091!-1 The science is pretty solid and has been around since the 1960's. Solar panels are used in mammography machines to detect x-rays. The levels needed to get a response in a typical PV panel is about 100mR/hr which would be a typical exposure on a radium pile. >>>> I have a friend who has lots of big solar panels on his boat.

This is 23 million rad! It takes only 400 to 600 rad to kill a person. Get real. This report is irrelevant. > http://www.osti.gov/energycitations/product.biblio.jsp?osti_id=4166955 "...At an exposure dose rate of 1 roentgen per minute the response was of the order of 10/sup -5/ volt ................" One roentgen per hour is huge, but a man can live with it for months, then he dies a terrible death. The current is 0.00001 volts. No good for RV power. Not real yet. That means irrelevant. > http://www.health-physics.com/pt/re/healthphys/abstract.00004032-196706000-00005 .htm;jsessionid=HGGTtj2s6yfvysTSp1b3pN9jM5nlp3SRv43vZQMKG0qrDx34syPP!391776677!1 81195629!8091!-1 "...a measuring method is suggested which makes it possible to measure with high precision the generated photocurrent at zero voltage applied at the detector which is independent of circuit parameters and proportional to exposure rate over a wide range. Measurements using this method are reported of exposure rates ranging up to 105 R/hr of 30 kV X-rays of 0.09 mm A1 HVL, and from approximately 1 to 30 R/hr of 60Co gamma-rays." The currents being measured in these silicon radiation detectors is on the order of picoamps for the radiation levels found from natural radium deposits. A picoamp is one millionth of one millionth of an amp. Not enough. This report is also irrelevant. > The science is pretty solid and has been around since the 1960's.

I have not heard of solar panels being used in mammography machines to detect x-rays. Is there a reference. Also, 100 mR/hr is unusually high for background radiation from radium. It could occur, but is highly unlikely. I have seen levels like this from piles of ore in a processing facility, but not in nature. Still not true.

This report is also irrelevant. Picoamps would be on the order or less than thermal noise for these devices since they are not cooled. Where do you see the reference to picoamps? >> The science is pretty solid and has been around since the 1960's. Solar >> panels are used in mammography machines to detect x-rays.

That would be solar detectors in a higher resolution grid. I'll get a good reference for you. Also, 100 > mR/hr is unusually high for background radiation from radium.

I don't think the radium emissions were generating electricity in those panels. They were pointed skyward, away from the radium and the radium emssions would have to penetrate metal, glass and probably the RV. The electricity he got when it was DARK out probably came from some type of induction from the Aurora Borealis. Was they guy in Alaska when this all happened?
