Making Alternative Energy & Reliability a Possibility for Your Home, Business, or School

Phase II: Designing a Specific System for that Structure
Do a more specific Scope based on Survey Results-
Formulate Reasonable Costs for Investment (given value of house, local property values etc.)
Final Presentation given to Customer by Team Members Time: 1 month- 1 year (varies project size)
How Many Completed - 10 Projects
Phase III: Construction Materials, Labor and Commissioning
Time Frame: varies—occurs in phases•Wells for geothermal• structure•PV•Wind generators
Cost: varies
III. American Renewable’s Energy Solutions
Renewable energy is any source that can be used without depleting its reserves.
Examples are wind, solar, and geothermal
Renewables are an important supply of energy, providing security, reducing need for fuel imports and helping to preserve the earth’s valuable resources
Renewable Energy Sources Wind Aero turbines
Geothermal GeoExchange
Photovoltaic (“PV”) BP Panels
Wind AEROTECTURE: A New Paradigm for Wind power in cities.
DESIGNER/PRICIPAL: BILL BECKER AEROTECTURE 510 SERIES Wind System
Cost Per Aero turbine: $6000/unit
Avg. Amount of Unit in Design: varies- owner has 4
Manufactured here in Chicago 21st & Racine by Windy City Power
Aerotecture 510 Series Wind System
Aerotecture 510 Specifications
Rated Power 1500 Watts Rated Wind Speed 30 m.p.h. Startup Wind Speed 2 m.p.h. Maximum Wind Speed 120 m.p.h Rotor Diameter 5 feet Number of Blades 2 Height 20 feet Weight 250 lbs. Generator Type Permanent Magnet Power Output Range 24-48 VDC
Aerotecture Turbines v. Propeller Systems
Aeroturbines Propellers•work well in urban settings with variable direction & gusting winds
•can have low visible profiles on rooftops &/or within other structures
• require no special code or zoning exemptions or high insurance premiums in suburbs/cities
•operate well in suburbs/cities where low noise, low visibility, & low/no vibration are mandatory
• work well in rural settings with steady uni-directional winds
•must have high profile towers above trees, buildings, & other obstructions
•- require special zoning & code exemptions & high insurance rates in suburbs/cities
•operate best in rural settings where noise, visibility, & vibration are less problematic
Aerotecture Aeroturbines v. Propeller cont.Aeroturbine Propeller• require minimum structural tower investments with no tower or ice ‘fall down’ concerns
•are low speed, caged, & are, therefore, easily seen by wildlife, creating no/minimal disturbances
•are simple, with low vibration, requiring infrequent inspection/repair with low maintenance costs
•are low-cost, simple, & self-regulating, using their inherent geometry to prevent ‘runaway’ without special controls
• require major investments for large structural towers & open space for tower & ice to fall down
•at high speed can become ‘invisible’ & kill birds while also creating noise/vibration disturbances
•are complex, with high vibration, requiring frequent inspection/repair with high maintenance costs
•require costly, complex, control & safe breaking devices to avoid ‘runaway’
Aerotecture Aeroturbines (cont.)Aeroturbine Propeller•can be mounted to roofs without special provisions & support PVs & other renewables without vibration/noise concerns
•self-regulate & start generating power in low wind speeds (6 mph & above) & continue generating in winds exceeding 70 mph
•are designed to fit within a great variety of ‘architectural surrounds’ & within cages/towers
• cannot be mounted to roofs without special tower/noise/vibration provisions
•start generating power in higher wind speeds (9 mph & above) & must furl blades or slow their spin speed in very high winds (45 mph & above)
•cannot be easily fitted within structural safety cages, towers, or architectural surrounds
Geothermal
heat (thermal) derived from the earth (geo).
Thermal Energy contained in rock and fluid (that fills the fractures and pores within the rock) in the earth’s crust.
Current Production ranks 3rd among renewables
Utilized through process called Geoexchange
Geoexchange
Works by moving heat, rather than by converting chemical Energy to heat like a furnace
Every GeoExchange Systems Includes:
• A geothermal Pump• A loop field of Polyethylene• An internal distribution System
Geothermal Heat Pump
Moves heat between the building and theFluid in the Earth Connection low maintenance- requires replacement of air filters Efficient: requires a little electricity clean
Savings over a period of 1 year
Earth Connection Transfers heat between its fluids and the earth Earth connections are called loops
4 Different types• Open • Vertical • Horizontal• Pond
The type of Terrain where location is on determines which loop.
Open Loop
• Requires abundant supply of well water
• Discharges water to drainage ditch or pond
• Processes heat energy from water
• Discharging water “return well” not as effective as sending to pond or lake
Vertical Loops
• Used land area is limited or soil conditions prohibit digging the more economical horizontal loops.
• A pair of pipes w/ special U-bend assembly at bottom inserted into a borehole (150-250 ft. deep/ton of equipment)
• Holes filled w/ special grout solution for good contact w/earth.
Horizontal Loops
• Used: Soil conditions allow for economical excavation
• Requires more land • Trenches 5ft. Deep w/
multiple pipes placed in trenches at various depths
• Trenches require several hundred feet
• Where space permits, more desirable
Pond Loop
• Very economical to install• Requires pond or lake (8 ft.
depth)• Utilize water rather than
soil to transfer heat to and from pond
• Coiled pipe in water covers ½ Acre
• Avg. Home requires 900 feet pipe
• Reduced installation costs & high performance
How Geothermal Works
Earth• 47% Sun’s Energy absorbed
Earth Loops
Heating-fluid circulates - loop- heat energy transfer to fluid than to
Geothermal UnitCooling (Process Reverses)
-heat removed from home-Transfers to Earth Loop- As warm fluid travels through loop- cooled- earth serves “heat sinks” -Result: cool, dry air
Photovoltaic - PV Sun strikes a PV cell module
converting such into electricity Integrates with existing electricity Supply British Petroleum (“BP”) PV
Panels Distributor Windy City Power Cost: $9 per watt with out grants or rebates
Legal Issues
Owners of American renewable had battle with neighbors who didn’t like aesthetics of Wind turbines on their roof Result: American Renewable prevailed but now, neighbors are trying to require variances for a new house they are building.
Conclusion
American Renewable’s Integrative Approach is making renewable
