Current Table uses something akin to photosynthesis to charge your devices
The table is made up of dye solar cells, which can gather energy from light, even if the sun isn't beating down directly on the table. Below the upper edge of the frame is a number of hidden USB ports that are just sitting there, waiting for you to plug in your hungry and thirsty devices.
The designer has a whole collection of glassware that collects light from an ambient sensor. Put your glass on the harvesting shelf and all of that energy is "deposited" into a central bank from where you can access the energy to recharge the battery on your device, using the USB port.
You can see the Current Tablet by clicking on the video below. There is no word when the table or the glassware might be offered to consumers.
