Kindly I am Requesting you to give Training about Solar & Wind Power Generator to me, I will come to your company and please trained like us intrested students, because we would like to generate solar and wind power in India, if you give me a chance to learn about the solar and wind power generators that will be greatfull to me. Here I am Awaiting for your valuable replay, please don't forgate without miss replay to me. Thanks. MANJUNATHA SWAMY.K +91 9845178088, +91 9886327286. Dear All,

But, here are some random thoughts. Include a seatbelt to be worn at all times including during sleep. You will roll sooner or later. You don't need to break any bones at sea. When you pedal to the top of an ocean swell your craft will probably accelerate to high speed and shoot down the face of the wave and the slender bow will most likely dig into the face of the next wave creating a temporary submarine. The only photos of ocean rowing boats I have seen show a boat that is stout at the bow and stern not needle thin. Empty the bow storage area as soon as possible to provide more flotation in the bow if possible. Steering, have a rope around a drum at the top of your rudder post and have that rope come into the passenger compartment and along the side across the cabin and down the other side back to the rudder. Set the course buy pulling on the rope from any where in the boat. Clip it to a cleat to maintain the course for prolonged period. How about a single out rigger for stability instead of a heavey keel and ballast? Out rigger floatation prevents boat from leaning into it and weight when it is lifted by the wind prevents it from leaning the other way. (It worked for the Polynesians I believe). Flat bottom boat still needs keel to prevent just drifting with the wind. A light shallow keel that runs a longer distance along the length of the bottom resist the weather cock effect better than a very deep keel that is short from front to back. Human power, concider the addition of hand power. Using both hand pedals or push/ pull levers as well as foot power may move your boat along and reduce the wear and tear on legs only. But as I say I have no skill or qualification to give advice just some thoughts. Good luck in your ventures I have no skill or qualifications to give advice… But, here are some random thoughts.

All the power to you so to speak. You mentiuoned your power production problems. I met a guy at a business meeting that is producing a fluorescent reflective material It reflects light like most reflective material but the really cool thing is it draws in the suns energy all day and glows all night long. They are using it on truck loading docks drive through windows signs etc. Why can't you use it for your nightime running lights, cabin lights and reduce a little of your load.

Are you aware if there is some setting I have to use to make it show correctly? Every thing is out of line. Heya, Simply wanted to show you that the site is not loading correctly on my i phone.

I have made a really little wind turbine which weight less than 2Kg (+500g for the controller). The output power is rated at 200W. Actually it deliver 10% more than an Ampair 100. Diameter of the turbine is 78cm. Unfortunately my turbines are not yet in production (we are in pre-series validation) and I will need some more month to get them finished. If in some month you would like to have a real wind turbine on your boat :-) please contact me. For information and to clarify with datas what the other say about resistance with wind. My turbine create at full throttle (320W under 50Km/h wind) about 5Kg of axial force. We have a special device included in the turbine's MPPT controller which can minimize this effort by slowing down the rotor (and the performances) from 0 to 70% depending on the consumer will. I wish you a lot of success in your adventure! Hadrien Hi Greg,

Several ways to do this is to use a collet that tightens the gear to the shaft. They call then taper lock. The other way is to silver solder or weld it to the shaft and put the bearings on from the other end of the shaft with spacers between the bearings and use Locktite to glue the bearings onto the shaft. cheers Stewart Hi Greg

Power is energy per time, the rate of energy flow (or production, or consumption, or conversion). Watts measure power. In your spreadsheet and text above, you have integrated power over time. The last column of your spreadsheet should be in "Watt-hours". Power multiplied by time (Watts times hours) gives energy, and the Watt-hour is a legitimate unit for measuring energy. You meant to say above that your average daily _energy_ harvest is expected to be 168 Watt-hours (Whr), etc. Saying "Watts per day" makes no sense.
