This solar charger charges one gadget. Pop it on the window to get energy, the same way you'd plug the gadget to the wall outlet.

so swag

Are these comments still being read?

If you are implementing this as a suction cap, you really need to be able to incorporate it into some sort of phone or GPS mount.

eg a ball joint attachment compatible with the ever popular ram mount system


Big dilemma: vote for "Window Buddy" or, "Window Buddy Plus"??...Right now my vote is here because a universal battery would seem to add to cost, and I'm not sure about it's efficiency-transfering power to a battery, and then from the battery to a device. Seems like there would be a loss of energy just in that transfer of power.


I really like this idea. You would have to make sure that these don't end up utilizing cheap technology. If the performance of the solar panel was high end I think more of these would be sold in a serious market, as opposed to a novelty. I think you are really on to something here...


This stands out...


Spray-On Solar-Power Cells using nanotechnology can now be painted on any surface & when it dries becomes plastic and generates electricity. And can be used even under cloudy weather conditions, which scientists have said in several published articles would make them up to 5 times more efficient than the solar cells that cannot be used in cloudy weather.

Video here along with a great article about this breakthrough: http://www.mnn.com/earth-matters/energy/videos/using-nanotechnology-to-create-spray-on-solar-panels

However, I agree with other comments that what is shown in the drawing is too small and the angle is not right to gather the energy you are trying to harness.

Still will be an expensive project to make this concept into a viable efficient product. I am very much interested to see how the design Quirky chooses will test out in their prototype.

Hope the information here helps QDS.

Great idea, and I love this particular design. Please DON'T call it 'Window Buddy', though. "____ Buddy" comes up in every product naming session and it's really unbecoming of such swag.

love this.


One drawback to this design and many others is the orientation of the pv to sun. It's not optimal. Crystalline pv performance falls off drastically when positioned out of normal to the sun's rays. Some continued development of the geometry may be in order.


I like the aesthetic and the direction, but I think the surface area is technically undersized. The time to charge a small device such as a cellphone would likely take more than half the day. Consider chaining together these small areas to achieve the proper current needed to charge smaller devices more quickly. Also it leaves open the ability to charge larger items through the same principle.

About This Project

Concept Phase

In this project, we want you to submit sketches, images, videos, and other visuals that illustrate design directions for Brandon Craven’s Solar Charger. We’ll use the top concepts as a starting point for our final design sketches.

We want to open this product up past the window blinds application, so don’t be afraid to get out of the box on this one. When working on your designs, keep in mind what the user’s interaction will be like with the product.
