Please think of the trans kids and the LGBT folks and all the women affected by abortion laws, and drag queens trying to make their art. Come on Americans, you can do it.
  • Are we seriously using this as a wedge between one candidate or the other? I'd love to have full trans rights here like any other reasonable country but if the alternative is authoritarianism 2016 but with an actual plan this time then I'm not going to complain if I don't get everything I want.

  • ‘The Movement to Convince Biden to Not Run Is Real’
  • I'd agree with you, except that we're in the dark timeline where the DNC has burned us hard by making dumb electoral decisions. We're basically given another chance at 2016 where we have a democratic shoehorn vs a narcissistic authoritarian. I'm actually getting to the point where I regret not voting for Hilary because of how much of a shit show those years were.

    So, yes, I'd love to vote for someone else, preferably like Bernie, but it's far too late to recampaign. Especially since it's less than 5 months prior to actual elections. Given what was accomplished these past 4 years, I'd actually be okay with Biden if he would meaningfully do something to help Palestine.

  • ‘The Movement to Convince Biden to Not Run Is Real’
  • I think what everyone needs to realize is that it's already too late. It's been too late and it was too late months ago. There are no other options. The world will suck but will most definitely suck less than one being led by Trump. You have two effective choices, vote Biden or don't. It's unfortunately all we have at this point.

  • Vivalidi 6.8 released
  • I used to love Vivaldi, but eventually it being a chromium browser forced me to switch back to Firefox and it's children. If they switched over to using Firefox as a base rather than chromium then I'd consider it.

  • I tested a hydrogen-powered bicycle. Is this the future?
  • You're definitely not wrong. Gray hydrogen currently is the most common source, which is a byproduct or an intended product of petroleum cracking. This also is probably a reason why most petroleum companies chose to research hydrogen in the 2000s/2010s rather than battery or other renewable technologies, since it fits nicely in their existing pipelines.

    For storage, I'm pretty sure you can keep it at atmospheric pressure and temperature if space isn't an issue, but to actually fit it in a vehicle you'd probably have to use one of the techniques you mentioned.

    The Mirai's issues seem to be that it was just a foothold for consumer hydrogen without anything really backing it. You could almost say the same about EVs/PHEVs 15 years ago and look at them now.

    Honestly though, if we are able to scale up sodium batteries, grid storage and train usage might be moot. Ships could probably still use it as an alternative to diesel though.

  • I tested a hydrogen-powered bicycle. Is this the future?
  • Your hydrogen efficiency estimates are probably pretty close to what this bike can do. The lithium ion comparison is missing some losses, ~90% efficiency from voltage boost converter. Also, the hub motor/speed controller both add another 75% efficiency to the equation but this applies to both so we can negate it.

    As for being a hydrogen hater, what did hydrogen ever do to you? I think we'd all prefer a solid state solution that would minimize losses but we don't have enough battery infrastructure to accommodate all of our needs. Sure, hydrogen is not the panacea for fossil fuels or lithium batteries in cars but there are good uses for it. I think Hydrogen can potentially be a good replacement fuel for large shipping vessels like ships and trains, since size requirements aren't as much of a factor, or used in grid storage as a long term or spillover storage for renewable energy when battery infrastructure is at full utilization and other means aren't available.

  • The Power of Sand Batteries -- Revolutionizing Energy Storage... - YouTube
  • While it can be used in localized electrical power generation, this isn't exactly best suited for just that. According to the video, the typical household uses 60% of their energy towards heating on average. This type of battery would already be storing thermal energy in the form that you need for this, so any conversion losses would already be accounted for; it would just be radiative losses while distributing the heat.

  • ‘Magical thinking’: hopes for sustainable jet fuel not realistic, report finds | IPS report says replacement fuels well off track to replace kerosene within timeframe needed to avert climate disaster
  • Exactly. This is all about people trying to come up with a technological solution to retain the same unsustainable lifestyle we already have become complacent with. It's just not possible; we can't keep consuming over what's feasible and wonder why the consequences of overconsumption keep coming up.

  • Corn to Power Airplanes? Biden Administration Sets a High Bar
  • I wonder if it's some sort of rationale for keeping the corn subsidies while also framing it a a greener alternative to crude oil extraction.

    Edit: After actually reading the article, yes this is the case. Apparently their proposed methods emit roughly 50% less emissions, which I think might be worth it depending on how much is expended to grow the corn and process the fuel. You could be right in the end though but if there are less emissions in general, it might be worth it.

  • Making Infrared Cooling Paint From Grocery Store Items (w/Novel CaCO₃ Microsphere Synthesis)

    As soon as I saw this, I thought of how homemade radiative cooling tech like this could be used in a solarpunk society.

    What do you think?
