The scientists used lasers to fuse two light atoms into a single one, releasing 3.15MJ (megajoules) of energy from 2.05MJ of input – roughly enough to boil a kettle.
Why do we even study this? Renewables are the only way. This is a waste of money which is a finite resource.
Waste of money, which is a finite resource.
You are calling a self sustaining energy technology a waste of money, which is inherently a made up resource. Go be a downer somewhere else.
You're not even citing the right reactor. LLNL did that experiment, this reactor in Japan is to try to scale it.
This is a 100%+ efficiency reactor with the capacity to basically make itself run all on its own with automation. How many electrical generators can run on their own 24/7?
There's a difference between what works best now to meet our energy needs (renewables) and the furthering of the science behind nuclear technology. We can do both.
The current energy consumption of the planet is 113,000Twh (according to Wikipedia). Since every single Joule of renewable energy is some derivative of solar energy (solar, wind, tide, hydro, but not geo I suppose) the maximum energy we can derive from renewables is 765,000Twh.
The problem with that, is if we start to consume 10's of percent of the total solar radiation through "renewables" that would otherwise go into generating weather and other natural events, well I'm sure you can see the potential problems.
So, we have to get away from carbon intensive electricity generation, but we can't physically rely solely on renewables. Therefore we need fission/fusion.
There's obviously the case of our current economic system causing us to overuse energy in the name of profit (oil is so important because it makes energy cheap and thus easier to make profits), and a change in production/consumption/distribution priorities would likely cause huge decreases in energy needs globally. But we can only really consider energy needs based on what we know.
Whoops, I forgot the "achtually".
Nuclear fission, all types of renewable energy and soon-to-be nuclear fusion are meant to complement each other, not for one to totally overtake the rest
OK - let's ignore the shitshow of responding to OP's hot take.
What kind of research is this particular reactor going to do?
