Tech Level F

Levels below TL F are historical. Tech level F is the technology level of cheap power and advanced material science.
Fusion reactors produce power by fusing hydrogen nuclei into helium. Fusion reactors do not produce radioactive waste and though they do require shielding while operating they quit cold, allowing easy maintenance. Fuel is provided by integrated fuel tanks which last the lifetime of the plant, typically greater than 200 years. That means just about every fusion planet ever built is still in operation. Importing a fusion plant gives even the most backward world maintenance free power for centuries.
Power cells provide high density power via the use of superconducting storage banks. They come in a variety of sizes and are rechargeable.
Convergent devices reach their apex. The personal digital device capable of recording audio & video, playing it back, connecting to the cell communication system and net, as well as performing conventional computing tasks become ubiquitous. Wearable devices, such as com bracelets and enhanced view goggles are common fashion accessories.
Smart nanomaterials such as thermo-cloth become available. Thermo-cloth can be made into clothing. While fitting almost skin tight the material captures heat in its weave making the wearer cool. When exposed to cold temperatures the weave releases the heating keeping the wearer warm. Chameleon cloth or surface takes on the color of the background, making the wearer less visible. Gecko pads adherer to a variety of surfaces, without leaving residue, and hold many times their own weight. Living Material is a "Smart" material that can be programed to take on different shapes. besides the obvious uses to disguise bladed weapons and manufacture multitools living material can be used in the manufacture of adaptive lenses, clamps and climbing pinions, and even doors and windows.
Advanced computer systems store googles of data on dine size recording media. High speed computers perform complex calculation and database searches instantly, and calculate the impossible in a little while longer. Simulated personality programs make interfacing with computers easier. No true AI, only God can create a person.
