<p>Melatonin 1mg 2 hours before bed worked for me in combination with wrap-around orange glasses (that filtered all blue light from screens and lighting) for the last 2 hours before bed. Also take magnesium and chamomile tea regularly, that layer on top.<p>Individually nothing works, but the combination crossed a tipping point for me with radical change.</p>

And the clearer-headedness persists all day. That was never my pattern in the previous 30 years, no matter all the things I tried.</p>

<p>The best thing in their favour is how standardized and simple a wind turbine tower is. They know the requirements and their customers. It's much easier than a skyscraper, and it might let them start to scale production of the materials so they become more attractive to other applications.<p>However there is growth in mass timber construction generally. People are competing to build taller and taller timber skyscrapers.</p>

<p>"Steel is very strong per volume, so steel is a good choice when strength per volume is one of the main constraints. However, wind turbine towers are essentially empty inside so there is room to increase the volume by making the walls thicker. The Laminated Veneer Lumber (LVL) material in a Modvion tower has higher strength per weight and higher strength per cost than steel alternatives."<p>Strength per volume versus strength per weight is an interesting trade-off. They're arguing this could let towers get taller.</p>

<p>I like mindmap software for how intuitive it is, but if I want to enter and manipulate data that's a graph rather than a tree I haven't found a tool I like. Any recommendations? If it can handle flow left to right where physical layout has a meaning I would like it even more. Something I can work with low tech people on, where it can scale to hundreds of nodes but I can select only some to display at a time.
Thank you.</p>

<p>It might be worth thinking about where there were successful electric vehicles before cars. All the scenarios I can think of are times the vehicle purchaser is willing to deal with charging infrastructure in return for the benefits.<p>Milk floats were quiet and didn't need to haul heavy loads, which was convenient for early morning deliveries. Distribution point/dairy can be the charge point.<p>Golf karts/utility vehicles. Never stray far from their chargers. Being quiet makes them more comfortable.<p>Forklifts are majority electric, and that was before lithium. Cheaper to run than fuel equivalents. They're still majority Lead Acid. A lead acid battery is heavy (a positive for a forklift) and lasts a shift before charging cheaply at overnight rates or swapping out the battery if there's another shift needing to use it. Lack of combustion fumes for an indoor warehouse or factory is real nice.<p>On technology specifically, range is next to useless if you can't tell how much you've left. I understand that tracking energy in and out the battery to a high level is not easy for a BMS - sample at the wrong rate and the potential error in over/underestimating range is quite large.</p>

<p>Writing things down to remember them, you feel like you've dealt with it. Which can be a great help since you can empty your brain of distractions that pop up and do so in a way you feel you've not just forgotten something. And reread later you'll realise how little was really important outside the moment it came up.<p>But if you place an artificial burden on yourself to follow up on everything that might be interesting, then that's probably overwhelming and shows a lack of prioritisation. That might be due to a lack of a system to prioritise, or it might be a lack of goals. Asking why you do it might feel you work backwards towards the goal - is it an ambiguous sense of professional development, or is it simply an enjoyment of pursuing novelty that means you keep turning up things that you feel you should come back to, but because novelty is the goal you never do. These might miss the mark with you, but they explain for me a lot about why I do the same things.</p>

<p>Sign language has a different grammar. At least in British Sign Language. Simplistically, put the object of the sentence first so it's clearer what's being talked about.<p>For someone who is profoundly deaf from birth and who can't lipread, the way we speak and write is a massive struggle. Cochlear implants before a year old are much more common now, while the brain is still more malleable, so there's maybe less and less deaf people who are totally profoundly deaf and you may not realise what it's like for them if you never come across them.</p>

<p>I've tried apps for tracking habits, which was great as it freed up Todo lists and Todo apps from lots of daily habit type tasks, however I stopped looking at it after maybe a year or more of useful use. Possibly I added too many things or the daily scan became too boring.<p>Being on a device is the primary distraction I've been hunting for an offline solution.<p>Presently I'm using checklist memo boards (cheap plastic things with toggle switches) that are on the walls of different rooms of the house with reminders for that place. So it's in my field of view and I'm reminded in the approximate place I can do something about it. Pieces of paper on surfaces get covered up and forgotten about, but these hang on walls.<p>Exercise specifically isn't a strong point, but trying to get outside during daylight has been a good motivation for me. Also doing things semi-useful like mundane gardening with an interesting podcast can be really engaging for me as hands and head are both occupied. Useful fidgeting I suppose.<p>I'm interested in trying an underdesk treadmill, I think that might work for me well.<p>This seems to work best for me, although I've got a lot of room to grow and improve.</p>
