The concept of using digital currency to prepay for electricity isn’t a new one – Gamaroff himself was involved in a previous effort back in 2014 aimed at facilitating prepaid electricity to South African residents using bitcoin.
Yet the new effort takes a more philanthropic approach, emphasizing bitcoin's use case for international aid through its crowdfunding platform structure.
As demonstrated by Gamaroff and Hesse, the project involves two components – the smart meter programmed to accept digital currency and positioned at the building set to receive power, and the crowdfunding platform through which donors can contribute bitcoin.
Gamaroff shared photos on Twitter prior to the MIT event, showcasing the installation of the smart meter:

Donors who contribute using the platform can see how much electricity a school consumes over a given period and can calculate how much power will be contributed based on how much BTC is given.
