Nice to hear from you again. I’ve seen the Solar Roadways project on several enviro-sites and it seems the media is eating it up. They even picked up an endorsement from Republican Senator Mike Crappo (R-ID), which I found most surprising:
Keep in mind, Solar Roadways started in 2009 with a $100k grant from the Dept. of Energy. Solar Roadways already had their day in the media spotlight back in 2010. The now-closed blog Infrastructurist panned the idea as "dubious" and "batshit crazy" based on a few thumbnail calculations using basic transportation engineering standards required to build roads.
Solar roads are and enviro-media darling, that’s for sure. My take is that there might be a few test roads built, but overall the idea is impossible at this point. It would cost tens of trillions of dollars to build at tax-payer expense. Dozens of policies, thousands of laws, and countless transportation and engineering standards would have to be rewritten (and pass congress). All 50 states would have to voluntarily change their transportation regulations. Not to mention the public objections, lobbyists, and litigation that would add decades of delays.
For those inspired by new technologies like solar roads, you have to answer the basic policy questions: What are the procedures to change transportation laws? How would you get congressional support? What does it take to change one rule (never mind hundreds of rules for solar roads) at your state’s DOT? Inspiration often times has to respond to, and outlast, very serious objections…
If you have not used Metro or regional transit in that time frame, you will need to touch your card to a SmarTrip® target at a faregate, fare vending machine or bus farebox to let the system know where to deliver your products. You must then wait one business day if you touched a target at a faregate or fare vending machine or two business days if you touched a target at a bus farebox.
If you try to pick up your product at a rail station or bus, and it’s not available for you yet, please try again at the same rail station or the same bus line the next business day.
The system can store up to four product load instructions at a time for a single smart card. After those four products have been loaded to your card, the next group of up to four product load instructions will be issued and will be available to load to your smart card.
In other words, if your “SmarTrip” Metro Card doesn’t work after adding money to it, “Meh, just go away and come back tomorrow. Might work. Might not.”
This really is an answer in Washington, DC’s Metro FAQs section. My Metro Card is connected to an account online. I added money to the card thinking - silly me - that I could use the Metro Card at the metro station. Nyyyyyyyope!
