Eclectic and Enigmatic Energizer
The Eclectic and Enigmatic Energizer is an aspiration reward that was added in The Sims 2. According to its description, the technology behind it is "a puzzle wrapped in an enigma, held together with copious amounts of duct tape and bits of twine", and it certainly looks like a ramshackle contraption that's held together with duct tape and twine. Regardless of what it looks like, it works - though it can only be used five times.
The Sim using the Energizer pulls a lever on the right-hand side of the device, then steps into an old washtub on the left-hand side. If the use is successful, the Sim will be surrounded by a bright glow as his or her motives are boosted. However, failure will drain the Sim's motives, though it will not kill him or her.
Using the Energizer takes 30 Sim minutes. If the Sim was in gold aspiration when stepping into the Energizer, it doesn't matter if he or she drops into green while it's running. However, if the Sim's aspiration level drops from gold to green between the time the lever is pulled and the time he or she steps into the Energizer, it may fail. If the Sim's Energy is depleted severely enough, he or she may pull the lever, step in, then step out before the Energizer can start to work. This will not use up one of the machine's five uses. If Seasons is installed, using the Energizer will raise the Sim's temperature.
If Seasons is installed, the Seasons patch should be installed before using the Energizer.
