Question by demongelding1@hotmail.com:
What size solar panel needed to recharge a 12 volt deep cycle battery? PLEASE HELP?
Hello everyone. We are working on a solar charging system for a deep cycle battery, used to power a stock tank heater for our horse. I need to know how many watt solar panel I need to recharge this battery during daylight hours. We live in the Upper Peninsula of MI, also known as the tundra. We get temps -40 below regularly. So this info would be helpful. Thanks so much!!

HOW POWERFUL A WIND TURBINE DO I NEED TO RECHARGE MY ELECTRIC BOAT?
Oct 4th
Question by Chaco-Yekke Downyonder:
How powerful a wind turbine do I need to recharge my electric boat?
I am building a two-seater, electric catamaran, 21 ft. long, about 8 knots top speed, no sails, just two electric DC engines. I am aiming at a range of about 20 miles before it needs recharging, and my only recharging device will be a wind turbine. I have seen they do about 100 – 400 Watts when they are the marine type which usually attaches to sailboats; how long would it take for such a turbine to replenish energy in my boat, would anyone know? I am hopeless with these things, but I still love doing them.
Thanks so much!

HOW LONG DOES IT TAKE TO RECHARGE A CAR BATTERY WITH A WIND TURBINE?
Aug 5th
Question by Chaco-Yekke Downyonder:
How long does it take to recharge a automobile battery with a wind turbine?
I’m planning to build a catamaran from two surfboards, attach a DC pump motor, put a seat on it and a wind turbine (500W) and make this thing my commuter boat. It needs to cover 8 miles in under an hour and back, and I hope to recharge it over night using the wind turbine only (the thing will be moored in Otago Harbour, southern New Zealand, and I am planning to swim out to it in the mornings using a wetsuit).
How many batteries do you reckon I need, how huge an engine do I need to get up to about 10 knots, and how many wind turbines are necessary to recharge this thing over night?
As you can see, I am a determined fool.
