It's a low-maintenance system, says Kivioja. The company uses cheap, low-quality sand that's been rejected by builders instead of high quality river-sand which is used in vast quantities for construction, leading to a global shortage.
"There's no wear and tear involved with the [heat exchange] pipes and the sand. The fan is the only moving part and it's easy to replace if necessary," says Kivioja.
Sand is a very effective medium for retaining heat over a long period, storing power for months at a time. And there are other benefits too. "The sand has a very long lifetime: it can heat up and cool off any number of times," says Kivioja. "It will get denser after a while so needs less space. At that point we can add more sand."
Has he said where we get more people, Bill? Basically, all the people we have are employed.Mike Rowe has been saying that for years.we're gonna be in trouble in a few years.
There's plenty of people. They're just not here. That's fixable.Has he said where we get more people, Bill? Basically, all the people we have are employed.

From the Washington Post newspaper article I mentioned earlier: "Steyer blames some of the shortage on cultural assumptions about working in fields like construction or electrical work. “Over the last 20 years, there has been very negative messaging to millennials and Gen Z about the trades,” he said. “There were a lot of articles saying, ‘All blue collar jobs are going to go away, everyone is going to be a knowledge worker or a care worker.’” That’s going to have to change. Some projects are already underway to increase the pipeline of available electricians...There are skilled trade labor shortages everywhere.
Concrete masons top the list with 904% growth in demand compared to pre-pandemic numbers.
Electricians have risen 130%.
Plumbers are up 129%.
And carpenters are up 121%.
And of course trucking. There is also a shortage of skilled auto mechanics.
This seems like a fairly broad issue of increased demand for skilled trades coupled with not enough people and a low unemployment rate.
Plus, many don't want to do manual labor. They are going to be a tiktok influencer or video game star.
Seems like we need to get more people who don't mind manual labor, train them, pay an attractive wage. Where will we get these people?
