How do we create or adapt infrastructure within homes or workplaces so that DC appliances can be adopted?

If you are a lucky one living with a resilient electric grid, happy days. But consider those too far away geographically or economically to join in the energy bonanza, which the fortunate have taken for granted their entire lives. Read our blog and let us know your thoughts on how we can innovate, challenge and question the status quo.

    The nearest we have at present is USB - up to about 2A at 5V...



    FYI, the latest version of the USB Power Delivery standard (USB PD3.1, May2021) allows up to 48VDC at 5A on the standard USB-C connector.  According to my calculations, that represents a field strength between adjacent pins on the connector of 2.28kV/cm!   There are several reasons why, despite the now 240W power capability, USB is not suitable as a general purpose portable appliance power spec (see attached).  I have discussed this with the Chair of USB-IF, and he agrees.
