The Academy is a building in Cities of Tomorrow in which futuristic technologies can be researched. The Academy itself can be purchased for 25,000 Simoleons, and additional controlnet facilities can also be purchased under the same category. Academy technology usually takes a facility or add-on to a facility, such as a garbage dump and garbage incinerator, and replaces it with a advanced version, in the case of the incinerator, the garbage atomizer. Most of the technologies are relatively cheap, or comparable to a regular facility, but some. such as the ground scrubber or fusion power plant are expensive. However, if you have a large city, it is often worth the investment to reduce air pollution or make a generally green city.
