You could join the resource industry, there's a labor shortage and there's all sort of vocational training. Some jobs require minimal training others more but you can be up and running in as little as 3 months for something relatively skilled. It's a refreshing feeling to have a job where the deliverables are very specific and day to day like you need to move this crap from here to there and that's it, no thinking about tickets or infrastructure or having to liaise with 8 stakeholders, nah bro supervisor said you need to help the guy move the drill cores, that's it for the next 5 days.
There is such shortage of skilled contractors. It's unreal, so I've considered getting in via being an electrician.
The starting salaries always stop me though. How can I reset the salary clock 10 years?
Maybe if I had started out at 20 on this route I could do what my father did: carpet cleaning and supported two sons and a homemaker on his one truck operation. We were solid middle class. All the needs met.
It's amazing what quality hard work, calling people back, and time can do.
One avenue might be to start doing IT work with and for a local electrician, and expand from there. If you're comfortable with computers, they could offer you as the low-voltage side of things.
You can contract the pcb work out on fiver and have the boards made at one of the Chinese board houses nowdays. I think I've seen people on Fiverr that provide turn key solutions you pay for it in turnaround spread and back and forth though.
The tubes are called earth tubes or ground-earth heat exchangers. If you look for geothermal heating you'll end up getting the wrong information, mostly for ground source heat pumps. The earth tubes aren't strictly speaking geothermal though, they're massive thermal reservoirs that you're taping into. You extract heat and then putting it back later either from day-night cycles or seasonal cycles.
Well it does not have the heat pump. So you will only ever get the temperature the ground is at. In his case the temperature of the ground is 11C. Which I guess is fine for the greenhouse with the additional sun gain.
This is nowhere near enough for human habitation comfort let alone hot water.
Yea, the difference is in capex cost and capabilities so the best you'll get is the ground temperature. Ideally you put a ground source heat pump but the energy needed to run it is high, COP for a ground source heat pump is like 3-6, cop on earth tubes are like 30 because you're only running a fan but you get whatever temperature the ground is.
You wouldn't be able to know how many years exactly from the core drilling visuals, for that you'd need to assay the cores for the grades, build a mining block model and then develop a mining plan from that. It's more of a qualitative "oh dam they've struck gold a lot of it" sort of thing that would move markets. Disclosures to markets in mining need to be done publically and with proper backing of data, legacy of BreX salting their core samples and reporting the motherload of gold mines.
Dam, didn't think I'd see another mining person on hackernews. Exploration geology that far down is wild. Was it core sampling all the way from grade or only in mineralized zones?
Core sampling the whole way. Outskirts of jundee at wiluna. Punched a few holes down the side of the pit while I was there and the deep holes were for underground to work out where they were going. Most target zones 800-1200. I got lucky as the drillers I offsided with were absolute guns so we got the hard stuff. Best day we cracked >100m in our 12 hours and cross shift got 80m. 22mins was out fastest 6m off memory. That was shallow work tho, deep holes can take 45m just to pull a core tube.
I don't drill any more but do kind of miss the work.
Make a shield for an Arduino, kicad has a template for the dimensions and positioning of the headers. A fun one is to make your own Arduino board, take the design for the uno and layout your own version and see if it works, there's plenty of guides on how to position stuff and it should get you introduced to the more complicated concepts in PCB design. Order the board from jlcpcb, can't beat them in price for 2 and 4 later PCBs.
Tried that, management still insisted I get all of it from Fastenal, great pricing and they have an online catalogue, but ffs it takes a week to get stuff in.
10/10 agree for Canadians McMaster Carr is a godsend. Can order random stock material and have it tomorrow and have a certificate telling me exactly what stuff is with a nice cad model. Their search is the best though, can write some half assed description of what I want and it'll just deisplay what I want. Their mobile website is garbage though.
Energy input is the other. It takes at minimum the combustion energy to reconfigure the molecules but most of the processes happen at high temperature and pressures which takes energy to do.
I understand input is an issue, but why aren't renewables cheap enough to solve the energy input part of the problem? Don't solar panels cost next to nothing nowadays?
How much must renewables decrease in cost in order for such fuels to be economically competitive?
Bit flip probability is inversely proportional to density of the storage media so denser might have you run into issues. Also theres no point on building a recorder that's 10x larger than what you need if you're going to be limited by downlink availability. You could probably get away with all those SD cards in LEO though for a short missions, JWST falls into the category of missions where the price of that storage medium is going to be a rounding error vs the price it would incur if it randomly failed during qualification.
Bad comparison - Ingenuity was spec'd for five 90 seconds flights [1], JWST for up to ten years, depending on how much they have to use its rocket engines.
