On 2250, the Earth reaches a Type 1 civilization on the Kardashev scale at the current rate. This is achieved by computers with semi-quasi reasoning skills and fusion energy. This is impossible with anything other than fusion power plants. In 2011, Earth’s at .72 so hydrogen power plants will make it to .73.
Bottom line, nobody ever needs to be type 1 status with all the spacecraft crashes within 114 years since 1897 Aurora, TX in my opinion. Discovery should be 1000x easier especially with surgical laser instruments on spaceships (Roswell).
Laser Inertial Fusion Energy is supposed to work in 2020 far before any International effort. There is supposed to be a demonstration in 2012.
Newt Gingrich said that our fission reactors are on their last legs and need attention and funding since 2000
All you need is a really, really primitive dyson ring and some lasers for wireless transfer to be Type 1.
