Idea for Cordless Tool Recharging Mat

How about having an electromagnetic recharging mat where you place your rechargeable tools and they would recharge on the mat - instead of in the charging cradle?  For starters - There are many rechargeable tools, each with their own recharger.  Also, there are now more and more recharging mats out - for headphones, batteries, laptops, etc.
How about combining these existing devices.  The new concept could use induction between the mat and the tools to recharge.  In a work situation, the worker would use the cordless tools then return them to the mat for recharging - no holders or no special recharging holders for each tool.  The whole workbench could be a charging surface too.  Essentially, there would be one mat for all the cordless tools, instead of individual chargers. There could be adapters for existing cordless tools to make them work with this new charging mat.  This recharging mat could provide a low level electromagnetic field - enough to trickle charge yet not enough to warm metal objects substantially.
Possible Start Building Blocks –

• Existing concepts for cordless tools, electric toothbrushes, induction heating, etc.
