Regarding useful technologies from plasma, you might say that we’ve been using them since we first learned to create and manipulate fire, although a fire is not always a plasma.
Some more recent plasma technologies:
Fluorescent lamps
Plasma torches (welding, cutting, waste disposal, etc.)
Ion thrusters
Plasma displays
Nonthermal plasmas for food processing
Plasma medicine (surgery, sterlization, etc.)
Plasma antennas
“Those 57 years of fusion research cost less than half of what congress wants to spend this year on Stealth bombers ($68.1 Billion) - each stealth bomber costs around $512 million, so that’s one year of fusion research.”
What year is meant here? This looks like the estimations of the 80s. The bomber became much more expensive in the end. Let me cite wikipedia:
“During the late 1980s and early 1990s, the Congress slashed initial plans to purchase 132 bombers to 21.
Manufactured by Northrop Grumman, the cost of each aircraft averaged US$737 million in 1997 dollars ($1.01 billion today).[3][4] Total procurement costs averaged US$929 million per aircraft ($1.27 billion today[4]), which includes spare parts, equipment, retrofitting, and software support.[3] The total program cost, which includes development, engineering and testing, averaged US$2.1 billion per aircraft (in 1997 dollars, $2.87 billion today).[3][4]”
That would make more than five years of fusion research per stealth bomber!
