    Yeah, that is the whole issue. Figuring out fusion is not as cheap as putting a lump of coal on the fire. That's why we haven't done it yet.

    Commercial fusion power is possible but it is going to take a heck of a lot more engineering. We can't live on solar and wind power until then.

    Sure, but might as well shoot for it. If, by shooting for it, you are actually committing resources to try to achieve it.

    My worry is that fusion is going to become somebody's political objective and the whole thing gets polarized. Oh, democrats like fusion, therefore we republicans hate it. Or vice versa.

    Good details in this article: https://arstechnica.com/science/2022...ced-this-week/

    The power aimed at the hydrogen was 2 megajoules and they got 3 megajoules back out, but overall power to get the lasers to fire was 300 megajoules, and they can't repeat it without a long wait in between. The lasers were designed 30 years ago, so not quite the latest technology. The article makes it more clear about where we're at currently and other directions the research needs to consider.

    And there it is...

    It is still at least a decade — maybe decades — away from commercial use, but the latest development is likely to be touted by the Biden administration as an affirmation of a massive investment by the government over the years.

    US scientists achieve q>1 from fusion reaction, meaning, more energy output than input.

    This is a little misleading, because it counts energy put into the system but not energy needed to run the experiment. Still, an important milestone.

    I got back from South Africa this week. I stayed in Cape Town for a couple of days and then drove up the coast eventually ending up in Port Elizabeth. Every city and every hotel I visited was affected by load shedding for at least two hours a day. It was annoying. Some places, including the two Marriott properties, had battery backup or generator systems in place. Even then the power would go out for thirty seconds or so until the secondary power switched on. That meant the TV and internet had to reboot which oftentimes to five or more minutes.

    Southern Africa is experience daily power outages for hours at a time. This article explains a little bit of the reason.

    Maybe the above picture explains the following... and the generator shortage.

    Electric Vehicles Cut US Gas Consumption by a Measly 0.54%
    A new report shows that national gasoline usage barely changed in 2021, despite increasing EV adoption.

    ELECTRIC VEHICLES HAVE never been more popular. Just about every automaker is in the midst of an electrification effort, spurred on by impending government regulations around the world aimed at reducing our dependency on fossil fuels. But is the movement having an effect? Here in the US, plug-in vehicles are selling better than ever, despite supply chain shortages and frequent hefty dealership markups.
    [...]
    This report is not an argument against people buying EVs, of course; any gas savings is an improvement on turning that gasoline into atmospheric pollution that worsens climate change. But it should be clear now that EVs on their own are not a panacea to our transport-related climate problems, and the future will require many more people to walk, cycle, or take the bus to get to where they're going.
    https://www.wired.com/story/american...-0-54-in-2021/

    But by the time the price of gasoline hits $99.9/gallon next year I bet gas consumption will be down by 5%. Joe should raise the gas taxes and make it happen sooner.
