Techno Viking would instal large scale, ultra thin, carbon solor blockers limiting the heat the planet Venus recieves thus lowing its temperture. Technoviking would then add, atmospheric extractors, that use boallons to stay alowt in the dense atmosphere, convertying co2 to c, and o3, to make ozone, As the atomosphere becomes less dense the extracters would sink lower into the atmosphere, and switch over to convertiong co2 to c and ot, thus making a oxygenated atmosphere with less greenhouse capabilities, till it no longers requires the solor blockers to remain cool. Once their task is complete Teck No Viking then will use them at Mars as solor relfectors to heat the planet up, melting the caps, and createingan atnmosphere rich in water vopr wch will then act as green hous gasses to help warm the plent up.
