Net zero and net positive energy in the fusion world are deceptive terms. This basically just compare electrical power in compared to energy output of the fusion reaction. It doesn't include any secondary energy used in auxiliary system to run the system (like liquid helium production for Tokamaks) or the efficiency of conversion to heat energy capture to drive a steam turbine. I'm sure that at 24x7 operation in an actual use there will be allot of cooling needed to keep the lasers within appropriate temperature ranges. Oh, and they are now using magnetic confinement to improve the implosion process - so the electro magnets will have to be cooled as well.Holy Crap this appears to be a big step
Flying taxis in maybe 5 years?I was told we'd have flying cars by now, that was like 30 yrs ago.
They better look like this!Flying taxis in maybe 5 years?
Dubai is one of the smartest cities in the world. In this blog post, we discuss the prospects and current progress of flying cars in Dubai.www.dubai-marina.com
The U.S. Department of Energy (DOE) and DOE’s National Nuclear Security Administration (NNSA) today announced the achievement of fusion ignition at Lawrence Livermore National Laboratory (LLNL)—a major scientific breakthrough decades in the making.www.energy.gov
~LLNL’s experiment surpassed the fusion threshold by delivering 2.05 megajoules (MJ) of energy to the target, resulting in 3.15 MJ of fusion energy output, demonstrating for the first time a most fundamental science basis for inertial fusion energy (IFE). Many advanced science and technology developments are still needed to achieve simple, affordable IFE to power homes and businesses, and DOE is currently restarting a broad-based, coordinated IFE program in the United States. Combined with private-sector investment, there is a lot of momentum to drive rapid progress toward fusion commercialization.
it looks(?) like they are onto something with that much extra energy?
I'm waiting for days, but yeah.Perhaps an important (and long promised) step toward a workable fusion process, but to me a "breakthrough" implies a development that overcomes the last major hurdle (which this is not). What would impress me is a process that could be operated stably for hours rather than seconds.
