For me it's not about the fridge, its about the concept of transparency and secure that blockchain tecnology can provide.
Fridges are more secure if they're not connected to any external system.
If you want to buy electricity from someone, you:
- ask them
- they ask you how much you want
- you tell them
- they tell you a price
- you say yes or no
- if yes, you establish the supply somehow
where and why does blockchain tech appear in that sequence of events?
Also Im not shure, but I can bet that bosch and wien energie are developing this project looking for a profit but with out doubt its a good background for future projects with open source initiative.
it sounds dumb
