Windier locations produce more energy, which lowers the cost of producing electricity. Moderate to excellent wind resources are
found in most regions of the world. Although mountainous areas generate the greatest raw wind power in the country.
It is costly to harness wind on rocky terrains. More than 90% of flat land is exposed to wind, while mountain regions experience wind only on their ridge crests, meaning that they can harness approximately 45% of regional winds. Wind turbines have minimal impact on the land on which they sit.
WIND MILLS reduce dependence on fossil fuels, provide added income for the communities served, and provide well-paying, secure jobs.
We are a wind turbine and solar concentrator photovoltaic energy (CPV) product designer, developer and manufacturer whose CEO and senior staff have collectively over 75 years in the renewable energy field. Our state-of-the-art, innovative designs are particularly suited for developing countries, due to the ease of technology transfer that includes training components at all levels of facility operations including business administration for workforce development.
Our Vertical Axis Wind Turbine consists of the following major components and sub-assemblies:
Sub-components:
Permanent Magnet Generator:
Main Electric Control Panel:
Power Converter System:
The following table illustrates the advantages of our vertical axis technology over conventional horizontal axis designs:
PRE VERTICAL AXIS WIND TURBINE | CONVENTIONAL HORIZONTAL AXIS DESIGN |
1. Pleasant look and neighborhood friendly | 1. Generally not appealing |
2. More environmental friendly and preferred | 2. Unfriendly. Environmental group(s) complains |
3. Unlikely to injure/kill bird and bats | 3. Media reported of bird/bats injured or killed |
4. No noise or minimal | 4. Very noisy most of the time |
5. Very little maintenance throughout its life (between 1% and 3% annually) |
5. High maintenance on gear boxes, blades and generator (between 2% to 12% annually) |
6. Blade(s) can be replaced on platform | 6. It is impossible to do on nacelle |
7.Require no heavy duty equipments for maint. | 7. Required heavy duty equipments for maint. |
8. Require no outside power for braking. No pitching and/or yawing required |
8. Required power for braking, blade pitching and yawing |
9. No gear box to worry about brake down and repair or noise or need lubrication or maintenance |
9. Gear box is a major issue for brake down, noise oil leakage and replacement. High oil leakage and require heavy equipment to move around |
10. Maintenance can be done on turbine with light hand tools |
10.Maintenance can't be done on tower top nacelle, unless just oil adding or lubrication) |
11. Good for rural community development | 11.Not suitable for rural community dev. |
12. Can be assembled or disassembled easily | 12.Assembly and dis-assembly is very difficult |
13. Easy for road or ocean transportation | 13.Not easy on either way transportation |
14. No wind shade | 14.Wind shade is a constant issue |
15. Does not interfere with radar signals | 15.There are complains about radar signal distortion |
16. Can be installed in modular form | 16.Can't be installed in modular form |
17. Can be installed on structural buildings | 17.Can't be installed on structural buildings |
18. No need for giant blades and tall towers | 18.Requires large blades and tower for same |
19. Lower installation cost, higher kW cost | 19.Lower kW cost but higher installation cost |
20. Stackable, hence better land utilization | 20.Non stackable |
21. Likely to create more jobs for locals | 21.Likely jobs in metropolis area due to their sizes |
22. Can be stand alone or utility inter tie | 22.Mostly utility inter tie use |
23. No air turbulence's | 23.Creates air turbulence's |
24. No electronic interference on aircraft radar | 24.EMF is a big problem and concerns are voiced |
25.Over all very cost effective for off grid | 25.Over all very expensive and has to be tied to grid |
26. Approval and permitting easy and lest cost | 26.Approval and permitting time consuming & costly |
27.Works w/o transmission lines | 27. Can't be used w/o costly transmission lines |
