Colorado Taking Steps To Get Its Own Hyperloop (usatoday.com) 98
According to USA Today, Colorado's transportation department is looking at the possibility of a Rocky Mountain hyperloop to curb traffic woes. You could travel from Fort Collins to Colorado Springs, a distance of about 125 miles with Denver in the middle, in less than 20 minutes. From the report: After partnering with Virgin Hyperloop One, one of the companies racing to develop the super-speed technology that essentially would transport vehicles and people pods on electric skates in a big pneumatic tube, Colorado Department of Transportation officials plan to spend the next nine months crunching the numbers to determine what it might take to bring this type of transit to Colorado. Above-ground routes are cheaper to build. But Musk's Boring Co., another company testing the technology, has been focusing on hyperloop transportation in tunnels. The proposed Rocky Mountain hyperloop would be centered at Denver International Airport and stretch about 100 miles north to Cheyenne, Wyo.; about 125 miles south to Pueblo, Colo.; and about 100 miles west to Vail, Colo. It carries a hefty $24 billion price tag. State transportation officials estimated it would need an initial investment of $3 billion just to get the first 40 miles from the airport north to Greeley, Colo., completed. Why a hyperloop? State officials estimate Colorado's population will grow by nearly 50% in the next 20 years.

State-run DOTs tend to love overly-complicated, expensive boondoggle project like this. It's much more exciting to talk about a hyperloop than boring solutions like "add more roads or railway lines". They spout nonsense like:
“We cannot build our way out of congestion, and that’s why we’re looking so widely at technology,” Ford said.
So, instead, they consider building a hyperloop? Nice. All you have to do is read a bit further down to see how they prioritize boondoggle projects versus practical solutions:
The Colorado Department of Transportation plans to widen the 70 miles of Interstate 25 from Wellington, Colo., to Denver, but that project is slated to be completed in increments with full completion not in sight until 2075.

Former Longmont Mayor Julia Pirnack is firmly in the no-compromise camp. She is trying to get $5,000 together so that a former Colorado Secretary of State Scott Gessler can explore whether anyone can viably sue the Regional Transportation District for the lack of a train in Longmont. Pirnack said in an interview earlier this month that since she was one of the people who pushed for Longmont to vote for FasTracks in 2004, she feels that RTD made a liar out of her because the commuter line promised in the FasTracks plan is currently not planned to reach Longmont until 2042.
Doubtless they're planning on finishing the Great Colorado Hyperloop sometime in the latter part of the aeon.

btw, you need to tune your FUD. The tunnel would recompress, not be explosive, and have little to no effect (except on efficiency of service).
Things inside the tunnel could decompress, although calling what they would do from a small hole like a rifle bullet 'explosive' is overstatement in the least.
Of course the pressure difference between what they would experience and what an airliner at altitude experiences is pretty damn small.
I suggest you are better addressing the boondoggle angle, or more to the point kicking the damn TSA out of your airports, since they are the ones destroying your particular industry.

The main problem with the Hyperloop concept is the low capacity. It's fast, but the cars are small and only carry a small number of people.

Those on/off ramps might be a lot more expensive than you're thinking - you need to do all of your acceleration and braking there so that you've matched speed with traffic on the main line before entering.

You're right about that much at least - which is why engineers are trained to pick the right materials for the job. Even more important are the design considerations - a tanker truck is designed to contain (usually limited) pressure, which is a completely different engineering problem than maintaining vacuum. You also shouldn't try to use a pressure cooker as a vacuum chamber.

They also have trains going to China and back which will improve quite soon, since China is investing billions to improve the speed.

Huh? You seem not to understand near vacuum. A hole or a dent will just get to get fixed, just like when a stone, a cow or a tree is on a railway line, with the difference, that a failed vacuum will instantly and automatically reduce the speed of the 'train' and prevent any 'accident' of "running into the bullet-hole" or whatever you think will happen.

There was an effort in Florida to try to get light rail from Miami to Tampa. In my mind the biggest obstacle was transportation once you get to the destination. I could understand something like this between two major cities with top notch mass transit, like New York and Boston. However, I don't think Fort Collins and Colorado Springs fit the bill, same as Miami and Tampa. Tell people "we can get you from CIty A to City B and then all you have to do is rent a car when you get there" is not going to get a ton of support. It works for air travel because the cost of a rental car is usually a small fraction of the airfare. However, for an economical light rail/hyperloop setup, the rental car cost now probably exceeds the long haul transport cost.

Upbound traffic could draw power from the road to reduce battery drain, while downward traffic could dump power into the road from regenerative breaking keeping them below the speed limit. And throw in a couple of commercial battery installations to keep things steadier.
In essence, average out the power requirements (less losses in the road and vehicle systems).
