Amazing! I'm happy to hear I could recruit someone on Lemmy :)

You can get them in the size of 500g or 1kg. I'd be happy to share from my stash if you live in EU.

This is where I document my build. I'm updating frequently at the moment.

The roadmap defines 3 milestone batteries. The first is released, it's a benchtop device that you can relatively easily build on your own. It has an electrode side of 2 x 2cm2. It does not store any significant amount of energy. The second one is being developed right now, it has a cell the size of a small 3d printer bed (20x20cm) and will also not store practical amounts of energy. It will hopefully prove though that they are on the right track and that they can scale it up. The third battery only will store significant amounts of energy but in only due end of the year (probably later).

Current Vanadium systems cost approx. 300-600$/kWh according to some random website I found. The goal of this project is to spread the knowledge about Redox Flow Batteries and in the medium term only make them commercially viable.

The aniolyth and catholyth are based on the Zink-Iodine system in an aqueous solution. There are a bunch of other systems though, each with their trade offs. The anode and cathode are both graphite felt in the case of the dev kit.

I'm building one and am super excited. Unfortunately I need to waid for some more parts to start experimenting.

You need Polypropylen filament for printing, graphite felt as electrode, grafoil gasket material as bipolar plate, brass plate as current collector (cut by cnc), silicone gasket material and a measurment device like a potentiostat.

If you're really interested, living somewhere in the EU, I could send you some stuff. I also have the chemicals in big quantities.

The guys at Flow Battery Research Collective have been designing a Redox Flow Battery development kit that you can build yourself using a 3d printer and a few tools. It's a desktop size flow battery that you can use to either do your own research, e.g. on different electrolytes or just to replicate their experimental findings.

Redox Flow Batteries have the potential to become grid scale or home electric energy storage solutions that are way better for the environment than current lithium based batteries. They can often scale power and capacity independently and allow for repairs.

The FBRC project wants to spread the knowledge on RFBs and help kickstart a global community that develops sustainable energy storage technology in an ope source fashion.

Beware that the project is still in its infancy and sourcing the materials can be a bit of a challenge. Be sure to ask around in the forums for help!

A gap in the pdf or actually a gap because you took years to figure it out? Both interpretations are funny.

So every time I drive my little car at night I'm filled with ungealthy rage afterwards and every time I think about what possible actions to take. This time I swore that I'd share some of my thoughts in order to help the movement gain more momentum. What comes is a collection of more or less well thought out ideas, don't take them too seriously.

  1. This is not really a political fight, it's about making the world better for everyone. We don't want to take away anything from you. We should try to not get the majority of people into a defensive position but rather educate about the problems and changes in lighting.
  2. Words are powerful. We need a word or wordmark that is easily understandable and that has a negative connotation without being too confrontational (like fuckyourheadlights).
  3. We should be cleverly about our strategy and take into account mass psychology. A big proportion of people have annoying headlights but either don't know it or maybe don't know how to make them less annoying. Make it so that the don't feel like they are the enemy but rather part of the solution.
  4. We should use official petitions or similar direct democracy tools if you have them in your country. Be clever and don't blindly start one. First gather a group of people willing to support it and have a good plan. Don't be confrontational, maybe ask for official investigation instead of bans.
  5. We should try to have science investigate the issue from a psychovisual point of view. This is all about people and not dry measurements and badly done specs. Try to include drivers eye-level and cars headlight height into the studies. Include spectral issues. White light can have a very different effect than more yellow or reddish light. Petitions could urge for scientific studies instead of bans or direct changes in policy.
  6. Include bike headlights, they are often as annoying as car lights. This issue highlights the alignment and height offset as parameters to the annoyingness and allows die hard car users to be included in the fight.
  7. The headlights issue is an issue for people in all groups of society. Be inclusive and use all kinds of platforms or media channels to spread the word. Be sure to consider 2. and use a common branding or word mark so small communities find their ways together into a big movement.
  8. Create songs, images and jokes to raise awareness of the topic. Don't point fingers but maybe make fun of people who have too bright beams without excluding them.
  9. Create material to help people to better align their lights or maybe dim them. Experiment with applying transparent foil to slightly reduce strength or change tint.
  10. Create a common signal to show other drivers that their lights are blinding. This could be for example: two short flashes and one long. Include this signal into your propaganda material. On bikes, remove your light and point into the eyes of the other biker until you have their attention, then point on their light. They will mostly understand the issue (unless they are dumb :/).

I hope to have brought up some interesting points for further discussion. What do you think?

[-] [email protected] 34 points 4 months ago

My problem is that I drive a low car (Ford fiesta) and most other cars are taller, this makes them way more blinding.

[-] [email protected] 26 points 4 months ago

Totally, I'm commuting by bike almost every work day of the year and it's infuriating how many cyclists have their headlights misaligned.

A new community where people can just vent about or actually do coordinate action against the pest of ultra bright LEDs.

This is hilarious. Thank you Lemmy!!
