The Blue No. 15 Electro-Fluid (青15号電機液, Ao Jūgo-Gō Denki Eki; Viz "Blue Electric Liquid No. 15")[1] is the fuel used for operating the Time Machine. The fuel was created by the Bulma of the future — and later on by the present incarnation of Bulma herself — and takes a year to make enough to fill even half of the time machine's tank with the future's limited resources. In the present day, however, with all resources converted towards the development of the fluid, Bulma was able to create a full tank within a day.[2]
