  Make it stackable with a central shaft interlink and guywire connection links for a permanent installation. Also, include an option for longer legs attachments for stability.

  An Ascent solar panel currently in production generates a real 45 watts and only weighs 3 lbs. Cost $279 and it rolls up.
  
  This wind turbine has no engineering data to support the design. Testing should should have been done BEFORE it was made to look pretty. Otherwise this is just a waste of people's time and gives YET ANOTHER bad rap to wind turbines.

  I love the design, it is beautiful. My comment relates to weight. If I take it hiking, even 1 or 2 extra ounces can add a lot (given everything one has to backpack in), so it should be as light as possible.

  Oh wow, I guess the real problem or questions to be asked is the power output and the structural stability of the device.
  
  I can image it being smaller than shown in the video and still have a relatively high output depending on the electronics within it.

  I've got some experience with small windturbines. The model shown in the video is unlikely to produce more than 1-2 watts. By contrast, it was sunny in those locations. A 3 square foot solar panel would easily do 5-10 watts. Much cheaper. Much more portable. Just better.

  There are slots for pegs guys, and if you made the base too big it would increase the size of the product. I agree that magnesium seems excessive for the application...if it needs to be pegged into the ground, why not just aluminium, or GF Polypropelene? Recharging station, cool, how about spark ignition for a campfire, actually become a torch, retractable spike (or screw) for securing the product integrated at the centre of the base...handy ice pick!?! :)

  Considering the high center of gravity, I think the base is insufficiently wide. How about a version that can be hammered/screwed into the ground..since this is for camping? Also, why magnesium? Not exactly the cheapest material...
  
  It's a very elegant and sleek design though.

  Possibly useful, and certainly a clean implementation. But I wonder about two things- at 10 mph a 1 square meter ideal turbine generates 35 W, but these spiral Darrieus mode turbines tend to only achieve a third of this amount. True, power output depends on the wind velocity cubed, but it would be nice to have actual numbers here. Also, the base has to be much larger or it will tip over in even modest winds.
