Time to Geek Out on Direct Current! Carl and Richard talk about the recent wave of discussion about DC in the home. Blame USB for part of it - everyone is using USB to charge devices now, and USB was never meant to do that... but in 2014, the new USB Power Delivery standard will be implemented to make it more effective. Richard digs into his experiences switching over to LED lighting in his house, and the craziness around converting from AC to DC at every LED light. So what about distributed LED lighting in the house? It opens the door to many more DC based solutions!
