Some new product ideas are cool, and some are downright crazy — but it's the ones that are a little of both that often turn out the best. Take the Electree ($200 and up) for example. This sculpture/gadget is shaped after a bonsai tree, but instead of leaves it sports solar panels on its branches. And what does it do with all the energy it collects? It charges an internal battery that you can then use to charge your phone or tablet. Wirelessly, even, if you'd like. It surely beats the "garden" of wires you deal with now.
