MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
Also, they are now making and selling a generator that uses a gravity battery generator for camping etc. You just hang it in a tree, lift the weight, and it slowly generates power until it bottoms out. They use a chain drive on the model I saw to allow for more customization of the battery length, and the device was compacted ridiculously small into the size of a wallet.
I guess in a sense, the model I saw was actually powered by the human energy of lifting the weight.
