Need to address demand as well as supply
7. How much electricity are you wasting?
Adrian McEwen - www.mcqn.com
I don’t know. Do you?
8. You could measure overall consumption
People are already doing this…
DIY Kyoto’s Wattson
The Owl
Efergy
Eco-eye
…but it’s very coarse-grained
See http://www.electricity-monitor.com/features-comparison-chart-i-26.html
for a comparison
Adrian McEwen - www.mcqn.com
9. Or measure devices one-by-one
Using something like…
Kill-A-Watt
Enerjar http://enerjar.net
But…
Results are displayed locally
Only measures cumulative energy

10. What if your electricity bill was
itemised like your phone bill?
Adrian McEwen - www.mcqn.com
See which appliances used the most power
11. What if your electricity bill was
itemised like your phone bill?
Adrian McEwen - www.mcqn.com
Spot patterns in usage over time
14. Taking control
What if devices were automatically
turned off overnight, or when you
were at work?
Adrian McEwen - www.mcqn.com
15. Taking control
What if you could easily turn off all
non-essential devices when you went
to bed, or left the house?
Adrian McEwen - www.mcqn.com
16. Taking control
What if ancillary devices (like a
printer) automatically turned
themselves on and off whenever the
master device was switched on or off?

17. The Mazzini Project aims to build
such a system
A family of autonomous, power-
monitoring, controllable sockets
Adrian McEwen - www.mcqn.com
18. The Mazzini Project aims to build
such a system
Simple plug-in-and-go installation
Monitors power usage and reports
regularly via wireless to a computer
or “master” unit
Attached appliance can be turned on
or off remotely via wireless, or…
…based on decisions from in-built
“behaviour” program

19. Scalable
Useful from the first one you install
Add additional units as quickly as you
want
Adrian McEwen - www.mcqn.com
20. Open Standards
Will use existing open standards for
data where possible
Will publish the specification for any
new data formats or communication
protocols defined
Adrian McEwen - www.mcqn.com
21. Open Source
Desire is to release both the hardware
and software as open source to
encourage new applications and
developments from users
Adrian McEwen - www.mcqn.com
22. Extensible. Reconfigurable.
Software can be upgraded or
reconfigured in the field – it will be
easy to download new behaviours
Investigating the possibility of non-
techie user hardware extensibility
