I worked on a rollercoaster/haunted house type ride at a sixflags park, made by the company MACK. they used a regenerative brake speed regulation system on the slopes to charge a super capacitor bank for power to climb the next slope.<div>
<br></div><div> mind you, this was a rather boring ride to many, was a family friendly ride with more focus on decor and effects. it was a great application of regenerative braking, with a storage system that works well with fast recharging.</div>
