Using The Prius' Regenerative Brakes To Power A Roller Coaster
from the neat dept
Notcot has this neat story about how some engineers are prototyping the idea of taking the regenerative braking system of the Toyota Prius, which effectively turns the "friction" into usable energy, rather than wasted energy, and using it in other contexts, such as to power a roller coaster. The general concept came from a program Toyota put together called "Ideas for Good," and one part of that included a commercial, where someone made the suggestion to power an amusement park with such a system. You can see that commercial here:Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Re: Re: Gimme a break!
Some of the older coasters have multiple circles of track around the ride with bumps and dips to use up the energy before entering the station, but a lot of the newer coasters, taller and faster, wedged into tight footprints (Top Thrill at Cedar Point comes to mind) definitely could recycle some of the braking energy to reduce the load needed to hit 120mph in 4 seconds. The braking at the end is pretty severe.

Additionally it's my understanding that this technology has been available in freight locomotives for a while now so it seems a bit more marketing than substance.

It isn't a good idea anyway...
You would be much better using vibration energy capturing instead.

Maybe that final moment of braking might realize a small return, however.
Of course, this would require more equipment on the coaster, which means more energy will be required to get it up the initial hill.
Yes, energy isn't free, but getting people thinking and innovating is free. Too bad patent trolls keep many from even bothering to mention their ideas.
I've had a few good ideas, maybe patentable, but the cost of getting a patent + potential legal issues just would mean a bunch of hassle for nothing.

Re:
Coasters don't have brakes on the cars for the most part, the brakes are really on the track. One common design is a metal fin sticking down, and the brakes grab the fins as the train passes.
If the fins were magnetic, and the "brakes" wire loops, then regenerative braking would work without having to completely change the coaster design.

New entry for the book of bad ideas
If the regenerative braking was designed to capture nearly 100 percent of the kinetic energy, the ride could go downhill almost as slowly as it climbed the next one using the regenerated energy. In fact, if we got rid of those pesky hills, we could just impart the minimum energy right in the beginning for the ride to gradually coast to a stop back at the beginning.
"Fun", safe, and green, all at the same time! Maybe this is why environmentalists are not normally called upon to design amusement parks. :)
