Always look for the information that's NOT provided.
First off. We have been able to do fusion for quite a long time. The problem is pretty much this... Controlled fusion that produces more power then you spent. Without blowing yourself up or burning the building down.
They have Not achieved that in my estimation.
And Why might you ask I say this. Due to the Information that WAS NOT included in the announcement. And its Very very important information.
Question that were Not answered.... or even posed.
How Much Power did it take to Start the Reaction ...... The only information provided here was the laser power. But what about CONTAINMENT!? You need a whopping magnetic field to Hold the reaction that takes a ton of power as well as the lasers to start the reaction/
Secondly. Just as Important. How Long Were you Able to maintain the reaction before containment field failure? See Problem 2 with fusion is containment. Super hot Plasma from fusion reactions is Crazy strong And highly Unpredictable. Field failure is usually measured in billionths of a second.
So what I see here is .... ITS GRANT TIME! news cycle.
the laser cost is the answer to your first question about starting the reaction.
to me i see that question and answer of the experiment equivelent to saying
"a match was struck which caused a bonfire of flames. exponential heat everyone exponential heat.. "
questions i have
yes they managed to produce more energy than the lasers.
but how much outside the building cost/energy was used to produce the pellet that was burned
EG fire is free. once you strike a single match you can then produce a flame as big as a bonfire or even a forest fire.. that can maintain more energy than the initial match and far longer than the initial match burns(until it reached your finger)
but its less about the energy creation exponential of the match vs bonfire.. its about the burning of material cost to make that also needs to be added
much like burning wood in a home fire place is not about the energy from a match exponentialised into a fire. and more about the wood cost to get that exponential amount of flame
where the cost of the wood is not free
...
also in a similar topic asking about the time scales of going from lab to commercial release..
the time delay is this
phase one show science theory to get gov science grants for R&D - done
phase two build prototype - done
phase three proof of concept - done
phase four get further R&D money to alpha test for efficiency gain
phase five get DOD grant to manufacture/beta test for military submarines
phase six sell finalised reactors to DOD
phase seven use proceeds to then expand into the business sector.
it is indeed at stage three-four. and yes it is "grant finding season"
the power wattage emitted was indeed more then the power input.
which for a small capsule the size of a petit-pois pea emitted enough energy in less than a nanosecond than the entire energy grid of america.. if you calculate the american grid energy divided down to same under nano second per watt scale
however to continuously feed this once every 60 seconds at scale to offer AC power for the grid. requires more capsules and maintaining the charge and discharge
which is where they are now at the efficiency test stage of prolonging the charge-discharge time to scale up to wattage per hour instead of sub-nanosecond
the 2.1mj to 3mj equates to
583.3w to 875w per XX pico second
and also scaling down the physical size of the building surrounding the the engine. so that it can be used upon submarines or built in small towns/cities
aswell as cost control and quality control of the capsules burned(the hydrogen equivalent of firewood
