Horizon Fuel Cell Technologies Renewable Energy Science Education Set

I ordered the whole kit based on the different types of energy units offered, and ultimately based on the description of the windmill from the site. Picoturbine.com offers the windmill standalone, with the following description: "The Wind Pitch uses 3-Phased AC Alternator similar to the commercial wind turbines." It could be that the windmill in the educational kit is different than the standalone windmill [doesn't quite make economic sense though] but the windmill in the kit only has 2 wire terminals on it. It is pretty impossible to get 3 phases of power out of 2 wires. A quick check on the oscilloscope confirms DC output - rectified too, since either direction of spin produces the same DC polarity. I'm not saying the product won't work for what I want it to do, but I was actually hoping that the description was accurate. I haven't heard of a cheap technology to make a constant frequency 3-phase power with variable wind speeds. Connecting a commercial wind turbine up to the grid requires the frequency to be at 60 Hz, otherwise something will have to change to make that happen [such as the wind generator becoming a motor, changing the windmill into a big outdoor fan]. Maybe this is just a marketing mistake. The contents of the kit were as depicted, with the exception of the output power...

The turbine front gets stuck very often. The trick to loosen it up: put it under hot water. Otherwise, it gives good data and is a great kit for experiments in the classroom.

Too expensive to be a boys game. The solar panel is too small to make work the fuell cell. No heavy Duty

Got this for my brother with high hopes. It was somewhat educational, but appeared to be finky in working like the directions said it would
