Other alternatives for our vision were solar power, geothermal power, and wind power.  Solar power wouldn’t work, because it has simply been thoroughly explored enough already.  Geothermal power would not work either, because not enough locations would allow for it to be used.  Wind power also wasn’t an option, because it wouldn’t work with our propeller farms and there would be no way to keep them floating if wind power were to be used.  Our best solution lies with the tidal farms. These farms can be placed in high tide areas and can either float or rest on the ocean floor and can harvest energy and pump it directly into the energy grid or store it in batteries.  Another advantage to the tidal farms is they are very low maintenance: they only require to be checked between once a week and once a month, and usually only require the batteries to be checked.  We concluded that these tidal farms would be the best solution, because although it’s not a fairly new idea, not much has been explored on it and not a whole lot is known.  Also, it allowed for expansion and did not require research expected of a university lab or company.
