  • Power to weight doesn’t matter as we are talking about using a solar panel instead of a roof. There’s no added weight. The car will already have inbuilt inverters so the only real weight add is the wiring. But also, this is a postal vehicle which will have large swings in weight anyways. A couple of extra pounds doesn’t make a difference here.

    Further, this isn’t a car, which has a much smaller surface area. These things have about 10 square meters of flat roof. That’s a peak output of ~3kW. (realistically, probably closer to 1.5kW average throughout a day) which translates into 12kWh of charge in any given day. Roughly 10% of the battery capacity could be restored daily.

    For large vehicles, like delivery vehicles and busses, the math on making the roof out solar panels instead of steel changes.


  • The one thing I wish they did with these things is make the roof out of solar panels.

    These things are going to spend most days sitting outside in direct sunlight. They have nice big flat roofs which makes them pretty perfect to throw on solar panels. You likely would not need much charge infrastructure for the new vehicles and you’d have cut the ownership cost down even more significantly (especially in states with high electrical rates).

    Regardless, these things are a no-brainer even without solar on all the vehicles. These are low speed vehicles with dedicated routes and loads of stop/go action. There’s not a more clear place to use an EV.


  • How many people will vote in a county is super predictable. There are only 2 reasons to run out of ballots

    1. Turnout is unusually high (Not likely).
    2. You printed less ballots than you needed (Really likely).

    That’s it, that’s the end of the reasons. You can literally print the same number of ballots for the last similar election and you’d have a good chance of having enough at least for most of the voting with some good early indicators that you need more at the beginning of the election. To run out 2 hours into an election shows you didn’t even print as many ballots as you did for the last major election.

    The math for how many ballots to print is “last similar election * (county growth percentage * last election turnout percentage) * 1.05”. That’s it. That will cover enough ballots for pretty much any election except for an extreme one where turnout is WAY higher than what could be predicted.

    usr does mean user. It was the place for user managed stuff originally. The home directory used to be a sub directory of the usr directory.

    The meaning and purpose of unix directories has very organically evolved. Heck, it’s still evolving. For example, the new .config directory in the home directory.




  • You know what would really help small businesses, like a lot? Public health insurance (covering things like vision and dental). A huge part of the cost of doing business is benefits for employees. Well, with public health insurance that’s a huge budget item that suddenly small businesses don’t have to pay.

    Want to make it better? Expand social security to be something you could live off of. Boom, now you as a small business owner don’t need benefits like 401ks. Your employees will be well taken care of by a government ran pension.

    Want to go a step further? Expand public housing, public transport, and food security programs. Now all the sudden a business doesn’t need to pay top dollar because the cost of living for everyone has been significantly decreased. You can easily find low wage workers and hire crews of them because the added income for everyone is more of a bonus rather than a necessity.

    What else could you do? Reduce the full time work week from 40 hours to 30 hours. For a small business, it means you can actually focus on having your employees doing useful work rather than having them hang around an extra 10 hours a week doing nothing. For the employees, now they have spare time on their hands which means more opportunities to interact with the community and small businesses.

    By taking care of the basic needs of the population you give the population a lot of spare capital and time. All of which can stimulate the economy to new heights.


  • Yes, but then being unwilling to take any concession is not. The green party could, for example, pull itself off of ballots in key states or elections when the Democrats agree to their policies.

    Running a doomed to fail candidate that only weakens the likelihood of the most left candidates and pulling progressives out of the Democrat party is a bad move.

    Say what your will about RFK, he’s getting political power from Trump by dropping (if Trump wins). What will the green party get? Nothing.

    Dropping and endorsing after concessions is the real way for a minority party to weld power. Running no matter what is just delusion that works counter to any goal you might have.

    Here’s a quote from the site you cherry picked

    Some people may choose to go vegan, for some it may be because they do not believe in farmed animal practices and animal exploitation, for others it may be due to environmental concerns. Whatever the reason The Vegan Society is here to support everyone on their vegan journey.

    Gee, looks like the vegan society also recognizes some people become vegan because of climate change… Or maybe you are going to redefine more terms so you can win your argument.



  • Got it, so you are emotionally defining veganism in such a way that you aren’t actually vegan if you don’t get there for emotional reasons.

    If that’s your definition of veganism then of course nobody can get there with reason. You’ve created a tautology with your emotion filled definition.

    For the record, veganism is defined by MW as

    : a strict vegetarian who consumes no food (such as meat, eggs, or dairy products) that comes from animals

    also : one who abstains from using animal products (such as leather)

    https://www.merriam-webster.com/dictionary/vegan

    That was the definition I was operating under. Sorry I didn’t Intuit your arbitrary definition you pulled from “eat meat.com” or whatever you got it.


  • Meat production is a prime contributor to climate change. Large amounts of resources go into raising meat. Further, cattle and pig production (not so much chicken) is the prime pathway to food contamination. Whenever you see lettuce recalls because of e. coli, that’s because animal shit got mixed in with the lettuce or the water for the lettuce.

    Choosing not to eat meat because of these facts seems like a pretty rational choice, no emotion involved.
