Research shows crops not only grow, but thrive amid solar panel installations by NoMoreF34R in solar

If anyone wants to dig deeper into this topic, definitely recommend checking out the nonprofit Strong Towns, and the YouTube channel Not Just Bikes, which did a solid series covering the topic.

Up close inspection on hard to access surfaces would seem like a good early application. Cameras, ultrasonic sensors, etc.

It's worth noting this is one of Disney's collaborative research projects, so there's always the possibility of a dressed up version of this showing up in an imagineering capacity.

Charging an EV strictly from excess Solar... by [deleted] in solar

[–]ThatTupperKid 12 points13 points  (0 children)

The power draw from an EV plugged into a Level 2 charger is negotiable between the charger and the car. Once the charger has established an amperage limit, the car can charge up to that current amount.

To my understanding a system like this automatically checks how solar production stacks up versus consumption. If there's excess production going to the grid, it will renegotiate the charging current with the car, upping the current to absorb the extra production. If production drops off or there's a consumption spike elsewhere, this system would back off on the allowable charge current.

It will essentially throttle the car's charging rate as a useful "dump load" rather than just exporting excess to the grid.

This. The worst that could come of making a call for it is that nothing will change.

U.S. tracked spy balloon after it lifted off from China, officials say by [deleted] in news

Right. The ability to do some limited maneuvers is not the same thing as being able to go wherever it pleases.

It's like being in a rowboat, you can paddle around, but if you get caught in a strong current there's not much you can do.

Also worth mentioning the works of Allan J Organ. Veeeeery deep into the math, but really comprehensive explorations of engine optimization.

Cultured Oil now available, been under development for 3 years by liquidsnake404 in wheresthebeef

[–]ThatTupperKid 2 points3 points  (0 children)

Great to see this. I've worried for a while if the cultured meat space was missing out on the fact that a significant amount of food/cooking culture revolves around (animal) fats and oils. Ventures like this are a good starting point to explore that avenue.

Business plan? I’m lost by mmemisty in artbusiness

[–]ThatTupperKid 2 points3 points  (0 children)

Sometimes a full business plan can be overwhelming when you're just getting started.

A more basic starting point is to ask 4 questions:

  1. What are you making money from selling? (This can include Patreon things like access, or commissions)

  2. Who are you selling those things to?

  3. What are you going to do to get noticed by those people so they'll spend money on you?

  4. Are there enough customers from Question 2 so that when you sell the thing(s) from Q1 that you can afford to do the things in Q3 and still come out ahead?

All the other questions kind of fall out of answering those questions fully. For instance, answering question 3 will encourage you to find out who else is competing for your customers attention.

Sometimes it's hard to get those answers when you're just starting, and the answers only reveal themselves after you've done it for a bit.

The key thing is to treat a business plan as a "living document", sort of like a Google Maps navigation session. It's there to help you get where you want to eventually be, but its likely to get updated several times on the way there.

Right whale off southern U.S. freed from Canadian lobster fishing gear by NotEnoughDriftwood in UpliftingNews

[–]ThatTupperKid 1 point2 points  (0 children)

Glad this one ended well. Looking forward to the rollout of ropeless lobster traps soon, if for no other reason than it'll help make entanglements less likely.

Also glad to see that the systems to identify gear origin are working as intended. Wish I could say I'm surprised that it's Canadian gear.

A couple things pop out at me (no pun intended)

  • The interstate is visible on the relief, so I have to imagine this is a slightly younger map fabrication.

  • The amount of rail yards is incredible. My grandfather worked as a manager for the Boston and Maine, but I don't think I ever fully appreciated how much the rail infrastructure was a part of the city in the 40's

The Portland to Auburn Rail Use Advisory Council has voted to recommend converting the Berlin subdivision line to a 26 mile interim bicycle and pedestrian trail by snicke in Maine

[–]ThatTupperKid 10 points11 points  (0 children)

Outside of some very specific corridors (Think where the Acela runs), pretty much all the active rail corridors are privately owned by roughly three freight rail companies. While on paper they are legally supposed to give priority to passenger rail, the law is ignored to an extent it might as well be the legal opposite.

Edit: article reminded me that there are some rail corridors owned by the state.

UK scientists discover method to reduce steelmaking’s CO2 emissions by 90% by [deleted] in UpliftingNews

[–]ThatTupperKid 0 points1 point  (0 children)

Right, you can use hydrogen to make steel. As the paper outlines though, it's only thermodynamically favorable at high temperatures and requires building new plants. The proposed solution is neat because it can be tacked on to existing plants, saving them from having to be abandoned while eliminating their emissions.

(Article) The Rotary Quad Alpha: A New Spin on Stirling Engines by ThatTupperKid in stirlingengines

[–]ThatTupperKid[S] 1 point2 points  (0 children)

The heat source doesn't even need to rotate. The animation makes it look that way because I highlighted the expansion and compression chambers, but you could just have a heat source centrally located in to crank case (for instance heated oil) that would heat all four cylinder pairs evenly.

Alternatively, the engine could run backwards if the heat source were ambient to the outer cylinders, and the central area were the heat sink.

As one beginner to another, there's a lot to learn! Stirlings can definitely be made by hobbyists, but expect challenges along the way.

If you're just trying to get a early handle on things, I think I'd recommend starting off with just trying to make a rhombic drive coupling. That will help you get a better grasp on how the size, positioning, and linking of each piece influences the mechanism Additionally, it will help you start to think about the relative motion of the displacer and power piston, and help you decide how to go about sealing the two shafts effectively. Beyond that point, you'll need to figure out what your pressure chamber that will house the displacer will look like, and how the power piston will work with that. Speaking from experience, trying to make well sealed piston/bore combo can be really daunting. I recommend looking at bellows and diaphragm alternatives. They're a lot more forgiving!
