I'm often hesitant about mapping the unofficial trails, particularly the ones you aren't supposed to use. There are many around the SF bay area, some are simply non-maintained non-system trails, while others are illegal mtb paths

I often notice when OSM is wrong/missing data while hiking and I'll record a trace and update when I get back home. I enjoy contributing but I wish there was a bit more of a community aspect to it (or maybe I simply haven't f

Looks like there is ~10^−8 earth masses of oil and coal [1]. I can't seem to find the mass of magneisum on earth but its 2.5% of the earth's crust, which is apparently <1% of the earth's volume, lets estimate 0.1% of the t

Appears so: https://www.sciencedirect.com/science/article/abs/pii/S09596... Although, looks like much of this is done with hydroelectric processes (same with Aluminum production).

There are a few industrial processes used to convert magnesium oxide to metal, for example the Pidgeon process ( https://en.wikipedia.org/wiki/Pidgeon_process ) which I still remember learning about in my Materials Scien

Doesn't most of what you said also apply to magnesium? Seems like we'll never run out (2.5% of earth's crust), there are well established methods to refine it and you just react the hydride with water to generate hydrogen.

Very cool, I just ordered a couple radios to play with. Looks like the app is Android only although an iPhone app is under development. Any recommendations for a cheap android phone/tablet to use mostly for this application?

Our area publishes the water quality tests. Not sure how that would really depend on the EPA you can also easily just get it tested as you said

Deionized water is often acidic as protons are introduced to replace the other ions. Co2 also dissolves immediately from the air forming carbonic acid. Regardless I don't think it's bad for your teeth it's not concentrated or

I commute by bike and I miss it. I'm not motivated enough to just go for a bike ride around the neighborhood so the commute was really good at forcing me to get my daily exercise. I know this isn't everyone's experience but I

Amazon has one in the East SF Bay. Limited stuff but the inventory tracking seems good. Available via Amazon Prime Now.

In the East Bay Amazon via Amazon prime now carries numerous whole foods grocery items but has much more reliable inventory (it seems) and I actually get the items I order. They are missing a lot of fresh produce and curiously often have sl

As I said in my post, they don't get smelly so for me the $40 is worth it, they still last easily dozens of wears so the cost is minimal and I don't have deal with a sweaty smelly shirt in my bag at work. Also, I don't find a

I wear merino wool t-shirts to bike to work because they don't get smelly, however, they actually wear out much faster than cheap synthetic shirts. I usually buy them on clearance/sale for $30-40. $70-120 is nuts for a t-shit. I a

USGS maps are also amazing, not sure really what project they came from but you can get a very good topo map of anywhere in the country. Really nice to have for planning hiking trips.

Same with medicine. Although under-served markets are common you still have to market yourself in private practice. New specialists advertise to GPs to get referrals for example.

I like those silicone lids, I think I picked up a set on Amazon, until the most used size tore.

I think the analogy to your example is to have conducted a larger trial where the dose was given under different weather conditions, or in the case of the real vaccine vary the timing of the 2nd dose. I agree, if experts agree the likelihoo

Propose to the companies to conduct a trial to test your hypothesis on the effectiveness of a single dose? Until then the FDA policy is clearly data based and they are saying to follow the tested dose schedule from the clinical trial and no

Open street map is great for hiking trails, particularly around urban areas where the US government maps (USFS, USGS) are way too out of date and don't cover new trails. I routinely update OSM for trails around the SF Bay area as I hik

I'd say this is true in a sense that you "stand on the shoulders of giants", you rely on a lot of technology and science that has been developed by others. But small non-diverse teams can accomplish important (but likely smal

I think you mean iron ore not raw iron, there isn't really raw iron (at least not enough). I think you could simply re-melt "raw iron" with scrap steel in an electric arc furnace.

Other sites like Outdoorgearlab do this as well, although, I could be wrong, it seems like they strongly favor items that can use affiliate links to make them money, which makes sense.

Ebay has lots of junk (the worst being the people who drop ship items from Amazon marked up or just outright scams) but its also a source of really good deals that you really can't find elsewhere. Refurbished PCs, obscure electronics,

That's an interesting point, I tried to search but I couldn't find any examples. Can you really run a watercooled engine without coolant or a radiator in arctic (-40 to -50C ambient temperatures?). Its not like an air cooled engin
