It looks kind of fragile, though. I can't find product specifications, like what material is in the blades. Where I'd use one, there might be heavy winds coming up without warning, so I need something that will survive harsh weather. What about winter?

Finally, no more depending on batteries or solar power or fossil fuel generators?

Portable wind turbine has sparked a craze and lets you harvest renewable energy almost anywhere

Janulus, a company based in Minnesota seems to have nailed a need that society has been craving.  They have built a portable wind turbine/battery combo that can charge your smart phone or your electric car.

The turbines come in one of four sizes and strengths.  The smallest, weighing in at 1.4 pounds, will give you 50 watts of power.  They scale up in size from 50 to 400 to 1,000 and finally to 2,500 watts, the largest of which can still fit in the trunk of your car.  The Kickstarter for these new models exploded on day 1 and has almost reached their goal of $50,000 as of this article being written.

An "all-in-one" shelter system has been developed for mountaineers. Inside the shelter conditions remain comfortable whatever the weather outdoors, thanks to a sophisticated dehumidifying system and a fine-tuned temperature control mechanism.

I have been waiting for something like this to replace tents and sleeping bags. Must be fine for QRP / SOTA expeditions into the mountains? Maybe also for certain other contingencies?

With a great avatar like yours, yes, you're IN.

BTW, welcome to the board!

Thank you very much on both points! That avatar is actually alive and  spark(l)ing:

Can you count me in?


I live in Norway, but my Midwest relatives are coming over this fall, and I guess they wouldn't mind bringing me a T-shirt, if I am the lucky winner?
