Gigantic solar PV raft always sailing low-latitude Pacific Ocean. There, rich sunshine, mild winds/waves, and little typhoon risk. Electricity transported by myriad EV batteries or H 2-gas. Solar PV modules, thin flexible type, integrated with solar cloths. A 25km 2 raft, consisting of 40000 subunits of 25m square jointed. Estimated economically feasible if H 2-gas price is 50% up. Further innovation in design concepts realize 0.25 USD H 2/m 3. Huge rafts should be accepted internationally to sail in ocean...
