Port Innovation Workshop Final Report
The Ports of Seattle and Tacoma, in collaboration with RMI and the Puget Sound Clean Air Agency, held a workshop to address environmental impacts and operational inefficiencies in container shipping. Participants identified 44 ideas categorized as leadership, partnership, or 'Blue Sky' opportunities. Key recommendations include the electrification of yard hostlers, the creation of a centralized transportation information system, and the implementation of a lease-to-own financing model for drayage truckers to acquire cleaner vehicles. The report also explores long-term 'NuPort' concepts, such as unmanned ships and wind-powered vessels, to minimize total energy expenditure in the global supply chain.

RE-EVALUATING STORMWATER THE NINE MILE RUN MODEL FOR RESTORATIVE REDEVELOPMENT TECHNICAL APPENDIX
The document provides a detailed framework for 'restorative redevelopment' in the Nine Mile Run Watershed, focusing on shifting from conventional 'end of the pipe' stormwater conveyance to site-based infiltration and treatment. It details conceptual designs for four representative sites—Hunter Park, Edgewood Crossroads, Regent Square Gateway, and Sterrett School—and proposes a comprehensive policy framework to overcome institutional barriers to green infrastructure.

Hypercar® Vehicles Frequently Asked Questions (FAQs)
The Hypercar concept, developed by the Rocky Mountain Institute (RMI), proposes a 'whole-system' approach to vehicle design to achieve fuel economies of 90 to 200 mpg. This is accomplished through the synergy of advanced polymeric composites to reduce mass by 50-65%, aerodynamic improvements to cut drag by 40-50%, and hybrid-electric drivesystems that recover up to 50% of braking energy. The document asserts that these vehicles can maintain safety standards, including in collisions with heavier cars, and could be compatible with various fuels, including hydrogen via fuel cells. RMI estimates that production-volume Hypercars could appear in the early 2000s, with costs comparable to conventional vehicles.

Speeding The Transition: Designing A Fuel-Cell Hypercar
The paper proposes a 'hypercar' design—characterized by ultralight composite bodies and hybrid-electric propulsion—to overcome the traditional barriers to hydrogen fuel cell adoption. By reducing vehicle mass and aerodynamic drag, the authors argue that the required fuel-cell capacity is significantly lowered, making the technology economically viable sooner. Modeling of three PEMFC scenarios shows that such vehicles could achieve high fuel efficiency (up to 124 mpgequiv) and long ranges (approximately 925 km) with modest hydrogen storage. The document further suggests that the mass production of PEMFCs could be accelerated by their application in stationary building power systems, which could eventually displace traditional thermal power stations.

Hypercars: A Market-Oriented Approach to Meeting Lifecycle Environmental Goals
The document proposes the "hypercar" concept, which utilizes a recursive "mass decompounding" process to create ultralight vehicles. By combining advanced composites and hybrid-electric drives, the authors argue that cars can achieve significantly higher fuel economy and lower emissions without sacrificing performance or cost. The paper examines the lifecycle benefits of this approach, including reduced embodied energy in manufacturing, lower in-use emissions, and the potential for high-value recycling of polymer composites through processes like low-temperature catalytic pyrolysis.
