HIGH RELIABILITY

The 4Navitas turbines are specifically designed to ensure low maintenance over their lifetime. The majority of operating machinery components, such as motors/gears/electronics etc are in a sealed walk-in cabin at ground level for easy access. The biggest source of failure in Horizontal Axis Wind Turbines ( HAWTs ) is the gearbox. Constant vibration on the transmission shaft reduces the lifetime of the gearbox. The 4Navitas turbines are designed with very high reliability gearboxes, thus reducing costs and downtime.

slide-20
SLIDE 20

HIGH RELIABILITY

HAWTs need to be able to detect when the wind changes direction, and to move the turbine blades to face into the

  • wind. This requires sensors to detect the change, and motors

to turn the turbine to face into the wind. The blades of the turbine also need to be adjusted ( pitch ). This requires sensors, a control system and motors. All of these devices can and do fail. The 4Navitas Vertical Axis Wind Turbine ( VAWT ) does not use any of these components. This leads to much higher reliability. The blades of the 4Navitas VAWT turn at only 32 rpm which reduces wear and tear on the turbine.

EASY MAINTENANCE

slide-22
SLIDE 22

EASY MAINTENANCE

1.CONVENTIONAL TURBINES HAVE THE GEARBOX AT THE TOP OF THE TOWER. A CRANE IS NEEDED FOR MAINTENANCE

  • 2. THE 4NAVITAS TURBINE HAS THE GEARBOX AT THE

BOTTOM OF THE TOWER. NO CRANE IS NEEDED

SLIDE 25
slide-26

slide-27
SLIDE 27

EASY MAINTENANCE

HAWTs have the generator and gearbox at the top of the

  • tower. This means that whenever a generator or gearbox has

to be replaced, a crane is required to be brought in to remove the faulty unit. Cranes are expensive to hire, and in many cases there is a waiting time for the crane to be available. During this time, the turbine is not producing electricity and money is being lost. The 4Navitas VAWT has both the generator and gearbox inside a climate controlled shelter at the base of the turbine. This provides for easy access to both

  • devices. Routine maintenance is required only once a year.

20 YEAR WARRANTY

MANY TURBINE MANUFACTURERS ONLY OFFER A FIVE OR TEN YEAR WARRANTY MANY WIND TURBINE MANUFACTURERS DO NOT HAVE WORLDWIDE PRESENCE SIEMENS PROVIDE ALL OF OUR WARRANTY AND SERVICE SUPPORT SIEMENS HAS A GLOBAL PRESENCE

slide-30
SLIDE 30
slide-31
SLIDE 31

20 YEAR WARRANTY

Warranty issues can cause major problems for wind turbine

  • perators. There have been a number of cases reported where

turbine operators have been left with a failed turbine for weeks or even months due to a shortage of maintenance staff as well as a lack of spare parts. Often, significant travel times may be involved if the manufacturer does not have representatives in the country concerned. World renowned energy experts Siemens perform all maintenance and warranty tasks. Siemens has a worldwide presence. The 4Navitas VAWT comes with a standard 20 year warranty.

5 HIGHER ENERGY OUTPUT

slide-33
SLIDE 33

HIGHER ENERGY OUTPUT

  • 1. HAWT’S ONLY TAKE WIND FROM ONE DIRECTION
  • 2. THE 4NAVITAS TURBINE CAN TAKE WIND FROM 360

DEGREES AND TAKE ADVANTAGE OF GUSTY, TURBULENT WIND CONDITIONS

slide-34
SLIDE 34
slide-35
SLIDE 35
slide-36
SLIDE 36

HIGHER ENERGY OUTPUT

HAWTs can only take wind from one direction at a time. The 4Navitas VAWT can take wind from 360 degrees, thus dramatically increasing power output. HAWTs can only use air that is smooth flowing, otherwise vibration problems occur. In an urban or city type environment, the air flow is turbulent and often gusty. This causes problems with HAWTs. The 4Navitas VAWT can use either smooth ( laminar ) or turbulent air.

7 QUIET BIRD/RADAR FRIENDLY

slide-41
SLIDE 41

QUIET OPERATION/MINIMAL SHADOW FLICKER

  • 1. MANY CONVENTIONAL WIND TURBINES HAVE AN

ANNOYING “WHOOSH WHOOSH SOUND”

  • 2. THE 4NAVITAS WIND TURBINE IS AS QUIET AS A QUIET

LIBRARY, ALLOWING OPERATION NEAR SCHOOLS, HOSPITALS, OFFICES ETC.

  • 3. MINIMIZES SHADOW FLICKER
slide-42
SLIDE 42

QUIET OPERATION

  • Diagram above shows typical HAWT noise profile.
The 4Navitas turbine has a much lower noise profile.
slide-43
SLIDE 43

MINIMAL SHADOW FLICKER

slide-44
SLIDE 44

QUIET OPERATION/MINIMAL SHADOW FLICKER

HAWTs are banned from many locations due to noise. The constant “whooshing” sound is annoying to anyone who lives close to the turbines. The 4Navitas VAWT is as quiet as a quiet

  • library. Our turbine does not make the sound described

previously. Shadow Flicker is a phenomenon whereby an irritating, moving shadow is cast across houses and offices that are close to an HAWT. This shadow can disturb livestock in rural

  • settings. The 4Navitas VAWT minimizes shadow flicker.
slide-45
SLIDE 45

BIRD FRIENDLY

BIRDS AND BATS ARE KILLED BY THREE MEANS IN REGARD TO CONVENTIONAL WIND TURBINES:

  • A. TRYING TO FLY IN BETWEEN BLADES
  • B. BEING “SUCKED IN” BY VACUUM EFFECT AT PROPELLER

BLADE TIPS

  • C. HEAT FROM THE TRANSMISSION SHAFT ATTRACTS

INSECTS WHICH ATTRACT BIRDS

slide-46

slide-49
SLIDE 49

BIRD FRIENDLY

Each year, many birds are killed by HAWTs around the world. Due to a form of optical illusion, birds think that they can fly between the turbine blades. At the tips of the propeller blades, there is a low pressure region which acts like a vacuum, and can “suck” birds into the blades. Insects are also attracted to the heat generated by the transmission shaft. Birds then follow the insects, and are killed by the blades. Birds fly around the blades of the 4Navitas VAWT, instead of trying to fly through them. Our blades do not travel fast enought to generate a vacuum. Any heat generated in our turbine is at the base, well away from the blades.

slide-50
SLIDE 50

RADAR FRIENDLY

  • 1. CONVENTIONAL WIND TURBINES CAUSE INTERFERENCE TO RADAR

SYSTEMS AND CANNOT BE LOCATED WITHIN APPROXIMATELY TWENTY MILES OF A RADAR IN MANY CASES

  • 2. CONVENTIONAL WIND TURBINES CAN ALSO MAKE WEATHER

RADAR SYSTEMS BELIEVE THAT THERE ARE STORMS WHEN THERE ARE NONE

slide-51
SLIDE 51
slide-52
SLIDE 52
slide-53
SLIDE 53

RADAR FRIENDLY

Many types of radar systems ( military, civilian, scientific, weather etc ) are present worldwide. HAWTs are banned from being anywhere near radar systems. This can mean within 20 miles of certain types of

  • radars. It is estimated that 30% of all HAWT wind turbine zoning

( planning ) applications are rejected in the UK due to objections from radar operators, especially air traffic control systems. HAWTs appear as flickering interference on air traffic control radar screens. The 4Navitas VAWT appears as a solid, non-moving object on the radar

  • screen. This is much more appealing to radar operators. 4Navitas has
  • perated a turbine very close to a military radar in the UK with no

interference.

8 ZONING PLANNING PERMISSION

slide-55
SLIDE 55

ZONING ( PLANNING PERMISSION )

ZONING PERMISSION IS OFTEN DENIED FOR THREE REASONS:

  • A. HEIGHT: OUR TURBINE IS NO HIGHER THAN MOST CELL

PHONE TOWERS

  • B. NOISE: OUR TURBINE IS ONE OF THE QUIETEST IN THE

WORLD

  • C. BIRDS: OUR TURBINE DOES NOT KILL BIRDS

slide-59
SLIDE 59
slide-60
SLIDE 60

ZONING ( PLANNING PERMISSION )

In many locations worldwide , zoning permission is denied due to three main reasons: height, noise and bird deaths. The 4Navitas VAWT is no higher than a typical cell phone tower. If the zoning committee allows cell towers, they should have no

  • bjection to allowing our turbines. As mentioned previously,

the 4Navitas VAWT is one of the quietest turbines in the world, meaning that it can be located near schools, hospitals, etc. Our turbines are bird friendly.

8 URBAN ENVIRONMENT OPERATIONS

slide-62
SLIDE 62

URBAN ENVIRONMENT OPERATION

CONVENTIONAL WIND TURBINES CANNOT OPERATE IN MOST URBAN/CITY ENVIRONMENTS, AS THE GUSTY, TURBULENT AIR CAUSES MANY MECHANICAL PROBLEMS FOR THE TURBINES. OUR TURBINES WORK WELL IN GUSTY, TURBULENT CONDITIONS.

slide-63
SLIDE 63
slide-64
SLIDE 64
slide-65
SLIDE 65

URBAN ENVIRONMENT OPERATION

Very few cities or towns worldwide have wind turbines

  • perating within the city or town limits. This is due to both to

zoning regulations and also due to the fact that HAWTs do not

  • perate well in gusty/turbulent areas such as those present in

urban areas. The 4Navitas turbine can operate in these

  • environments. This also means that the turbines can be

located beside the buildings they are going to serve, hence eliminating electricity pylons or underground power cables in certain situations.

MANUFACTURING PARTNERS

It was concluded the best approach to achieve excellence was not to create a manufacturing facility from scratch, but to create a team of manufacturing partners, world-leading experts in their particular sector.

slide-67
SLIDE 67

MARKET SECTORS

The VAWT is ideal and viable for: * Schools, Colleges, Universities * Agricultural units * Retailers, Shopping centers, Supermarkets * Service stations * Commercial buildings * Industrial units * Infrastructure sites * Sports facilities * Government, Local authority buildings * SME's

A VIEW FROM SPACE THAT SHOWS THE PROLIFERATION AND INCREASE IN ELECTRICITY USAGE AROUND THE WORLD

The world demand for electricity has increased significantly, not

  • nly in line with population increases being further fuelled by

economic development. World population has increased by 30% from 5.3 to 6.9 billion from 1990 to 2010.
