Rachel – tumbling Rocks - Let's take a closer look at power needs - good comment from Bret - AC
or DC?
*************************
Monica, Ken, Ben B - car charger - 34 kWhr per year? how many kW?,
Meter 21448 kWhr per yr (which one?)
Need to know how many kW = POWER needed
Ken - can build charger for $1500 - wind + solar + battery + inverter (and tie into grid)
FB- PSE will have to tie into grid
campus solar lamppost costs $5000 - how much power?
Amazon wind + solar $1500 - 150W
HAWT vs VAWT - 4 ft diam HAWT 72 W/hr, less for VAWT
- easy, educational, can be made with recycled materials
-
anybody can make these
we DO have enough wind. There's more inside the trees than on top of buildings (X)
PV: monocrystallin expensive, higher efficiency, black, lasts longer
polycrystalline looks shattered, lower e, doesn't last as long
film PV experimenta
Wind - Cape Wind Project - people worried about bird and bat mortality - Audubon says more are
killed (not by cars, but by fossil fuels)
Ben on wind - 2 m/s from the south not ... continuous - best on the coast Wind Power Resources
0.61 km/hr. "Sustainable wind speeds". What does that mean?
William - not convinced wind speeds are adequate. Units quoted are not consistent.
Z: yes, William is quite right, about both units and wind speeds.
Cite solar systems' POWER (kw), not energy (kw-hr). Power tells you the strength. Energy
depends on the time over which the system operates.

Tashina and Jeff - Sustainable dog feces disposable?
Wolf haven - bio fence - give wolf feces to rranchers to discourage wild wolf packs
Could we compost dog feces on campus?
Jeff - dog waste has issues - various nutrients - some plants could take over
- pathogens
- runoff can affect shellfish
- TC advises against composting pet waste
Tashina - Use it for landscaping, potted plants, mulch
gas powered dog waste composter at Landfill
Alaska dog mushers compost waste - need 3/4 lb per day, can reduce volume by 50%
They BURN the feces? NO, they compost hot (if done right – this is not easy).
Q - minimum number of dogs per day required for hot compost?
Q - Monica Szarvas - how would you collect it? T - plastic collector bins? Do a survey first?
Choose the highest concentration locations?
Q - NK - observe where people run their dogs... - kiosks with biodegradable bags - educational
component
Q - does disposal area get contaminated?
Gotta cook the compost
Talk with SWWAB - is this legal in Thurston County

Water Turbines and that Pesky Rain - Jess, Megan Lande, Shania
Micro-hydro - convert stormwater runoff to energy
Can be efficient, cost-effective, low-maintenance
Megan - financially sustainable? low energy producers... - good Q&H
Pluvia gutter system - from UNM students - pump pushes water thru gutter system - pump requires
too much electricity
Evergreen experience - Andrew Cannard - ideas to improve - bigger building, better wheel...
Downspout - little power, because we don't have downpours
Megan - CRC (gym) or CAB (Greenery) - have big roofs
Budget - but what's your idea? You just said none of these ideas were good?
They propose to construct turbine
Q - Brian - how can we figure out if it's financially sensible?
Nick - how about redirecting the flow, and concentrating it? Shania - yes, they did that at our HW
William - could maximize energy output with multiple turbines, conform to shape of gutter, have
more flags
Z - let's find that turbine that Andrew Cannard's group bought. Think about using rooftop tank, as
WZ suggested earlier
Bret - flywheel can store energy (Z - in lots of mechanical systems)

Urban forest - C sequestration - TREES
Monica Szarvas, Bethany, Sarah W, Julia M, Elise V, Fletcher K
CS - removal from atmosphere and held in liquid or solid form
UN Declaration of Human Rights - put it in eerspective
Clean Air Act 1970 authorized EPA to establish Nation clean air standards
Evergreen's Carbon Neutrality by 2020 proposal
Goal 3 - offsets and sequestration - we can help!
Q: How effective are trees on campus in sequestering C? Old, young, diverse...
Can more effective trees be planted on campus?
H: - about species
H - Consider ages and growth rates (z)
MAP - create a planting plan - Species report 2007
Different kinds of CS - biogeochemical, manufactured, and BIOTIC
Bethany - trees do it by creating rings (Z - wood!) - we want to make this more effective
BUDGET - wait, how are you going to do this? What are you going to do?
Fletcher - do trees sequester more carbon in their native environments?
- levels of ecosystem productivity
- urban trees in smaller groups
- mycelium and communication
Downed trees - how much C goes into atmosphere? how much into ground?
Z - TIME - growth rates and CS rates of old and new trees now
survival rates in the future
Brian - ivy? slow killer
Monica - would you consider planting non-natives? maybe, but nott invasives
Dex - any tax benefits from CS?
McKinzie - concern about mycelium? Fletcher - good answer, Monica S - doug fir needs mycelium
to germinate - Beth - symbiotic relationship, repeat answer
William - diff between trees
Sean - difference between micorrhizal relations with difference trees
Bret - whole tree is C - eventually gets returned - you want trees to grow forever Z - no more doug firs here in 50 yrs? what should we plant? See UW CIG (Climate Impacts
Group) tree projections
