Alternative Energy Using WINDSTAX®
WindStax® offers GTC a complete wind energy solution for the growing demand of direct distributed power. All the products are designed to be used as a “stand alone” system, or as part of a fully integrated alternative energy project. (Wind/Solar/Hydro). We design, fabricate, install, and service systems in the USA and select international markets. The focus is on commercial projects ranging from one building to community-wide microgrids and small-scale wind farms.
The core product is a steel frame aluminum rotor WindStax 20 and WindStax 40. These are the largest commercially available vertical axis turbines made in the USA. Because we are the manufacturer, each turbine is built to order including custom colors, gearing, and electronics for specific projects. The turbines are approximately 20′ and 40′ tall installed respectively.
We offer a smaller turbine 36″ diameter by 42″ tall made from fiber reinforced polymer. (The WindStax 3.0) This product is primarily used for Nano grids. We also have a WindStax 3.0 street light that uses wind and solar energy to run high lumen outdoor lighting.
WindStax® are non-directional and needs little wind to start operating. That means the turbine works in ever-changing wind directions with speeds as low as 5 miles per hour. The unique low-rpm, high-torque rotor design continues to work safely in high wind speeds that force traditional wind turbines to shut down. Generally, an annual average wind speed of 10 mph will provide more than adequate supply, to the battery storage system.
WindStax® has power on demand. The batteries store up to several days of energy using an advanced power management system. The electricity is 120/240V AC or 12/24V/48V DC. We also have high voltage DC options. The electricity is cleaner and more reliable than most utilities and can run everything from your lighting or air conditioning system to sensitive electronics.
WindStax® are portable. With little effort, the generators can be moved across the property or across the country. The WindStax 20 Ft weighs between 1200-2400 pounds depending on the configuration. All WindStax generators fit within the confines of standard ISO shipping containers, keeping shipping costs to a minimum.
WindStax® systems are smart. They utilize wind energy captured and stored in their battery systems first, only reverting to utility power or standby generators, if the wind cannot keep up with demand. Once charged, they revert to green energy. In that way, you use green and free power first and utility or generator power as back up.
WindStax® require no assembly. Each unit arrives fully assembled with the control systems ready to wire in. They do not require complex footings and foundations. High-performance batteries are in our microgrids are safe, spill proof and 100% maintenance free.
WindStax® are friendly to your neighbors. The generators are silent, safe, and ascetically pleasing. Their design blends into their surroundings while providing good, clean, and free electricity. They can be finished in various colors, assimilate with corporate color schemes and branding.
WindStax® are reliable. Traditional horizontal axis wind turbines are complex machines comprised of thousands of components that involve an extensive international supply chain. WindStax uses a small fraction of that many components and has only three moving parts – ALL WindStax are made and assembled in the USA.
WindStax® are friendly to the environment. The generators have a small footprint, they are nearly silent and avian friendly. There have been no documented cases of bird, bat, or even bug kills with vertical axis turbines.
WindStax® are sustainable. The rotor is built using renewable material in a proprietary manufacturing process. All materials including the tower are lightweight, highly resilient, and strong. We care about our workers too so we use strive for low VOCs in the manufacturing process. WindStax use low carbon footprint materials, fasteners, components, and fabrication methods on a mission to achieve LEED, SCAQMD, CARB specifications and VOC compliance.
WindStax® are government friendly. The units can be installed anywhere with a good wind approach. Most municipal zoning begins with regulations of towers and wind turbines above 60’. As equipment, they are not considered a permanent structure under most zoning regulations.
How much usable electricity does WindStax produce?
WindStax® 20 and 40 base units come with 120Vac/60Hz 4,000 watt continuous/5400-watt surge rated inverters. Larger units up to 17,600 watts are available with multiple units in clusters. That is pure sine wave power by the way, cleaner than many public utilities. We have 120/240Vac/60Hz single phase setups. Some 230V/50Hz international voltage options are available.
Every WindStax® system accepts more wind turbines or solar/hydro power, making your WindStax® scalable. Hybrid electronic options allows us to aggregate alternative energy into one centralized control and distribution system.
Electrical consumption is highly variable by region, season, time of day, and electronics. Ratings can be deceiving. To estimate how much power you need, is just a simple formula. Check this ( DOE website for estimating energy consumption link to be provided.)
How much usable electricity does WindStax store?
WindStax® use sealed maintenance-free 100 percent recyclable deep cycle AGM (absorbent glass mat) batteries. The storage capacity of WindStax® is measured in terms of amp-hours. The ampere-hour rating divided by the load in amps will provide the estimated time of that cycle. For example, a 12V battery rated for 200 Ah (for a 10-hour rate) will deliver 20 amperes of current for 10 hours under standard temperature conditions (25C or 77F). We use 12V, 24V, 48V, or 380VDC battery banks depending on the application.
WindStax® batteries are modular so we can increase storage capacity depending on customer demand. Our experts can calculate battery requirements for you whether you want 3 hours or three days of backup power. Theoretically, WindStax® storage capacity is limited only by the wind and solar power available to keep them charged depending on the duration of the off-grid load requirements.
For 20+ year life cycle in a non-toxic battery, we offer revolutionary Aqueous Hybrid Ion technology (AHItm) \
Micro Generation Facilities
GTC plans to develop a portfolio of micro generation facilities in the northeastern US. Ranging between one and 10MW. These owner-operated plants range from 20-200 acres placed strategically to serve utility and nearby commercial customers through long term power purchase agreements. The plants utilize a proprietary blended generation model using PV, exclusive large vertical wind turbines, and natural gas cogeneration options including micro turbines and fuel cells. Integral utility-scale battery storage smooths the variable nature of wind and solar production to provide energy on demand. An advanced microgrid provides smart grid options which introduces other revenue streams including grid stabilization, energy shaving and shifting, and load leveling.
Advantages to the customer includes reliable alternative energy capable of operating independently from the utility grid. This is a fundamental shift to energy as a service rather than a commodity. Doing so can help companies lower energy costs and carbon footprint while meeting sustainability goals and enhancing overall business performance. Strategic investment in energy is already helping many Fortune 500 companies see substantial returns and realize new revenue streams. Micro generation plants bring this model to more of corporate America due to their small footprint and low environmental impact.
Wind and solar generate energy on nearly opposite cycles and are at their best in different seasons and latitudes. Vertical wind turbines in clusters no higher than 60 feet avoid complications of traditional wind farm development and operate in lower wind speeds. They supplement solar energy in marginal solar regions while consuming little land area. A large underserved market potential exists in the US, for example suburban industrial parks. Furthermore, the proposed distributed energy generation model is consistent with global goals to reduce carbon emissions, enhance energy infrastructure resilience and security, while helping the US develop a clean energy economy.
