yLooksSexier

• August 10, 2006 -- Venture capital investment in
  energy efficiency technologies more than tripled
  in the second quarter year-over-year
• Energy efficiency investments reached 60.9
  million, compared with 15.2 million in the same
  period last year..
• energy management startup GridPoint raised 16
  million, Prenova raised 11 million, and
  Broadband Energy Network raised more than 2
  million. Fat Spaniel raised 3.5 million in
  March, and Comverge raised 5.5 million in April

Progression of WSN
2002, Early testing in etcheverry, evaluation of
Network for real-time controls (see nates
Master thesis).
2006 testbed evaluation of REM multi-agent
architecture with sense and actuation
capabilities, utilizing multi-hop wsn (based on
conclusions of 2005 studies).
2005 multiple site studies for communication Perfo
rmance (see Ota Wright, 2006) ?conclude Need
multi-hop network.
2006 field deployments of REM multi-agent system
with sense and actuation utilizing multi-hop wsn.

Energy Scavenging in Residential Environments
Challenge Published solar panel designs are
unsuitable for indoor environments. Solution
Implementation of a multi-source vibration and
photovoltaic energy scavenging and storage
design. Using data gathered from the Tmote
nodes, improved software defined routines
maximize performance.
Indoor nodes are exposed to a mixture of natural
solar with artificial incandescent and
florescent light.
A stack-able design allows different
combinations of energy scavenging devices (left).
