Gov. Hickenlooper shuts down U.S. 36 west of Lyons
Sep 22nd
In a rather draconian move, Colorado Gov. John Hickenlooper announced this afternoon that the State of Colorado has contracted with a Colo. National Guard engineering company to rebuild U.S. 36 between Lyons and Estes Park. Work on the highway has begun from both directions – from the Town of Lyons and the Town of Estes Park – with similar equipment and crews working towards each other.
In an effort to expedite construction, all traffic on U.S. 36 west of Lyons is prohibited, effectively immediately.
Beginning Monday, all access to Apple Valley Rd will be severely restricted between the hours of 7 a.m. – 6 p.m.
The closure applies to vehicular, cycling, and pedestrian traffic. The closures will specifically impact residents of Spring Gulch and Blue Mountain areas. Also, until this project is completed there will be no vehicular, cycling, or pedestrian access to Pinewood Springs.
At this time, there is no estimated timeline for completion of this project. We hope to be able to provide that information soon.

CU scientists: New battery extends range and safety of electric-powered vehicles
Sep 22nd
A cutting-edge battery technology developed at the University of Colorado Boulder that could allow tomorrow’s electric vehicles to travel twice as far on a charge is now closer to becoming a commercial reality.
CU’s Technology Transfer Office has completed an agreement with Solid Power LLC—a CU-Boulder spinoff company founded by Se-Hee Lee and Conrad Stoldt, both associate professors of mechanical engineering—for the development and commercialization of an innovative solid-state rechargeable battery. Solid Power also was recently awarded a $3.4 million grant from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy for the purpose of creating a battery that can improve electric vehicle driving range.
The rechargeable batteries that are standard in today’s electric vehicles—as well as in a host of consumer electronics, such as mobile phones and laptops—are lithium-ion batteries, which generate electricity when lithium ions move back and forth between electrodes in a liquid electrolyte solution.
Engineers and chemists have long known that using lithium metal as the anode in a rechargeable battery—as opposed to the conventional carbon materials that are used as the anode in conventional lithium-ion batteries—can dramatically increase its energy density. But using lithium metal, a highly reactive solid, in conjunction with a liquid electrolyte is extremely hazardous because it increases the chance of a thermal runaway reaction that can result in a fire or an explosion.
Today’s lithium-ion batteries require a bulky amount of devices to protect and cool the batteries. A fire onboard a Boeing Dreamliner in January that temporarily grounded the new class of plane was linked to its onboard lithium-ion battery.
Lee and Stoldt solved the safety concerns around using lithium metal by eliminating the liquid electrolyte. Instead, the pair built an entirely solid-state battery that uses a ceramic electrolyte to separate the lithium metal anode from the cathode. Because the solid-state battery is far safer, it requires less protective packaging, which in turn could reduce the weight of the battery system in electric vehicles and help extend their range.
Research into the development of solid-state batteries has gone on for a couple of decades, but it has been difficult to create a solid electrolyte that allowed the ions to pass through it as easily as a liquid electrolyte.
“The problem has always been that solid electrolytes had very poor performance making their use in rechargeable batteries impractical,” Stoldt said. “However, the last decade has seen a resurgence in the development of new solid electrolytes with ionic conductivities that rival their liquid counterparts.”
The critical innovation added by Lee and Stoldt that allows their solid-state lithium battery to out-perform standard lithium-ion batteries is the construction of the cathode, the part of the battery that attracts the positively charged lithium ions once they’re discharged from the lithium metal. Instead of using a solid mass of material, Lee and Stoldt created a “composite cathode,” essentially small particles of cathode material held together with solid electrolyte and infused with an additive that increases its electrical conductivity. This configuration allows ions and electrons to move more easily within the cathode.
“The real innovation is an all-solid composite cathode that is based upon an iron-sulfur chemistry that we developed at CU,” Stoldt said. “This new, low-cost chemistry has a capacity that’s nearly 10 times greater than state-of-the-art cathodes.”
Last year, Lee and Stoldt partnered with Douglas Campbell, a small-business and early-stage product development veteran, to spin out Solid Power.
“We’re very excited about the opportunity to achieve commercial success for the all solid-state rechargeable battery,” said Campbell, Solid Power’s president. “We’re actively engaging industrial commercial partners to assist in commercialization and expect to have prototype products ready for in-field testing within 18 to 24 months.” Important to the early success of the company has been its incubation within CU-Boulder’s College of Engineering and Applied Science’s applied energy storage research center, a part of the college’s energy systems and environmental sustainability initiative.
Solid Power is a member of Rocky Mountain Innosphere, a nonprofit technology incubator headquartered in Fort Collins, Colo., with a mission to accelerate the development and success of high-impact scientific and technology startup companies.
“We’re very excited to be working with Solid Power’s team to get them to the next level,” said Mike Freeman, Innosphere’s CEO. “This is a big deal to Colorado’s clean-tech space. Solid Power’s batteries will have a huge impact in the EV market, and they have a potential $20 billion market for their technology.”

Free transportation will be provided to flood victims seeking disaster center help
Sep 22nd
Increased traffic and the lack of transportation options in the mountains and foothills of Boulder County continues to be a problem for our residents and road & utility work crews. Similarly, residents impacted by the flood may have difficulty getting to one of the disaster assistance centers, either in Boulder or Longmont.
In order to alleviate some of the congestion and isolation issues of getting to and from Boulder from our mountain communities, and to assist residents getting to or from a disaster assistance center, VIA, RTD, City of Boulder and Boulder County are working together to provide accessible transportation options for plains and mountain residents affected by the flood.
Transportation to/from Disaster Assistance Centers and for basic needs
From Sept. 21 through Oct. 17, Boulder County’s nonprofit Via Mobility Services will provide flood victims with free on-demand transportation to Boulder County’s disaster assistance centers, as long as Via staff can safely reach the pickup locations. This free service will also be provided to the disaster assistance center in Estes Park. To schedule a ride, call 303-447-9636 from 8 a.m. to 5 p.m., Monday through Friday.
Via will also provide free on-demand transportation for any flood victim in its service area to access healthcare, food, employment, or other essential services to help stabilize their lives. Via can also provide information about mobility options and referral to other transportation resources that may be available in local communities. Call 303-447-2848 ext. 1014 or email egallegos@viacolorado.org for more information.
Mountain community transportation updates
Beginning Monday, Sept. 23:
- The Climb bus will resume service with a modified route from Gold Hill Road through Sunshine Canyon Drive to the Boulder Transit Center. The Climb is operated by Via. Please see www.the-climb.org for additional route and schedule information.
- In collaboration with RTD and Boulder County, Via will also provide two mid-day routes from Boulder to Nederland through Sunshine Canyon Drive using four-wheel-drive paratransit vehicles.
- RTD’s reconstituted large coach N route, will provide early morning and late afternoon between Nederland and Boulder via Highway 119 and Blackhawk. See www.viacolorado.org or www.rtd-denver.com for more information.
Via Mobility Services
Via is a private, nonprofit organization providing on-demand transportation, individual, and group travel training and mobility options information and referral. For more information, please visit www.viacolorado.orgor call 303-447-2848.
