| Energy Efficiency is coming to
the top of people’s
priorities list Mark Anderson predicts
the way technology winds are blowing.

Services (Global Business program). |
- Energy Efficiency is coming to the top of people’s
priorities list
- Every country is working on the smart grid
- It is a complicated thing to completely rebuild
the grid
- It’s not a case of replacing wires, it’s
installing the intelligence and knowing how it works
- To generate power in every building you need
the ability to feed both ways all the time
- You need a lot of computer power to control all
these different flows of stuff
- Sunlight is the ultimate source of power
- how do we store those protons,
- how do we capture them and
- distribute them through the smart grid
- with the most efficiency possible.

Then instead of worrying about scarcity
of oil, or regulations of shipping oil from here to there or burning
coal and creating atmospheric problems we have the free sunlight coming
down all the time and plenty of it, with an ever increasing number of
catchers it should drive the price of power down, and sunlight has no
waste products.

One answer to the above is the new innovative
Compressed Air Power Generation Systems+ (nGen
Systems) by IndraNet.
This system has the computing power (the
intelligence in the form of new smart grid software) and combined with
compressed air technology they have the ability to capture the solar
energy to generate electricity. This application is scalable from one
house to entire cities and will be the first true
Intelligent Power Networks - IPN's
(smart grid) of their kind. |

Professor Emeritus of the European Institute of
Business Administration who says economists are missing out on a major
growth driver for the economy. Robert Ayres is the author of several
books, including 'The Next Industrial Revolution', and the '13 Percent
Economy', which argues that the giant US economy functions on only 13%
efficiency in terms of energy use - meaning 87% is wasted. |

Energy Efficiency
-
Energy efficiency has proved to be a
cost-effective strategy for building economies
without necessarily growing
energy consumption
-
Negawatts—the
idea of meeting energy needs by increasing
efficiency instead of increasing energy
production
-
Efficient energy use is achieved primarily by
means of a more efficient technology or process
rather than by changes in individual behaviour.
-
In industrial settings, "there are abundant
opportunities to save energy
-
70% to 90% of the energy and cost for lighting,
fan, and pump systems;
-
50% for electric motors;
-
60% in areas such as heating, cooling, office
equipment, and appliances.
-
Up to 75% of the electricity used in the U.S.
today could be saved with efficiency measures
that cost less than the electricity itself.
-
For homeowners, up to 75% leaky ducts have
remained an invisible energy culprit for years.

Efficiency level, yes, it baffles a lot of people.
In fact it's quite simple,
thermal solar
people use a heating oil to transfer the heat from the solar collectors
(dish or heliostats focusing on a solar tower) to steam to drive a steam
turbine at between 200oC
and 300oC.
In this fashion efficiency is at best around
25%.
People doing Concentrated Photovoltaics (CPV) do also at best
25%.

IndraNet works with compressed air at ~1000oC.
This is what enables us to achieve over
50%
electrical efficiency.
The higher the temperature the higher the efficiency. |

Energy Efficiency of 90% -
YES!

Individual generators produce electricity at point o use
and communicate through IndraNet Minders to the grid |

Distributed Power Generation
Scalable
POINT-OF-USE power generators forming
Intelligent Power Networks
IPN
(Smart Grids)
The
New Business Model
has power being generated at point-of-use initially
using compressed air and a small amount of natural
gas, bio fuels or other alternative fuels, but
eventually
(3-5yrs) being fully solar augmented.
With the
clever use of the IndraNet Minders
this can allow the
generator to communicated with power grid in both
times of high demand and excess generation. This is
a more cost effective way of getting cheaper power
than is currently available..
Integrated with technology
enabling re-use of waste heat, this translates into
overall energy efficiencies of over 90% from primary
source to end-use (instead of less than
20% and often less than 10% efficiency in current legacy
systems) |

Energy efficiency in buildings |
|
One of the key means to reach the goal of emitting
50-85 % less CO2 by 2050 is to reduce the energy consumption in
buildings. The major CO2 contributors in Europe are illustrated left.
Heating and cooling are the main energy consumers in
buildings and account for two thirds of a building’s total energy
consumption.
However, most of this energy is wasted due to
inadequate insulation. By using well-proven energy efficiency
techniques, 70 to 90 % of a building’s energy need for heating or
cooling can be cut.
