Very interesting though that muzak is dreadful

Iāve for the last few week been seeing references to sand batteries. now the bbc have waded in. It seems Finland is finding a use for these batteries. As energy storage is a topic most green engineers are interested in. i thought I share this one. Complementary systems will definitely be advantageous in the coming years. As heat is a primary loss in energy production. capturing the heat loss, to me would see like a good idea. May bump efficiency by a few points. As in many awes have systems that would benefit. I couldnāt help myself. Thought it rude not to share. So there we go sand batteries.

Iām going to leave this here just a little something Iām working towards.
Itās a little rough around the edge need a little more work. Off to a good start though. Itās stainless steel. made with three tools. As that what I had to hand. It a follow up on a few idea and concept. Its totally a diy special. Can be made in 3hr without punching the steel. It took me an 1hr 1/2 to get this far. I was looking for feedback? Essential it a co-flow component. Made from a 50kg shelf unit parts. Essential each shelf was about Ā£2. When I got it! Iām looking to nest it in several layers that wrap around to for multiple layers co-flow. Not bad for b&q. Realised that body fabricator, would easily knock something like this up. With a better tooling selection. Even mass produced in a stamping press aimed at punching louvres. Much like the car manufacturers. It looks like an equal sign to me. When marked out. This is about stage 2 in production steps. Just need to repeat the louvre. That faces the other. to complete intakes and exhausts. Essential 2 shelf sandwiched together. I doubt it cost me more than Ā£20 to get this far. So here we go!
Basic steps cut a slot, form Louvres. Canāt be any simpler. I am looking to use edge gaskets. Maybe have 3D edge profile printed. Effectively making a lenticular wing profile. The deck will need some work to ensure it rigidity. simple ribs or even stay bolts to hold it together?
Even a a scratch built project I donāt think I got off to a bad start?
The magic of aerodynamic. So still a few decisions to make. But it what Iāve got to hand. With the skills iāve got at my disposal. So rudimentary and simple it canāt be missed.
The above split is a discussion about a concept for a submarine and a discussion about wave energy. This is not a discussion topic so Iāve moved the comments. If you would like to discuss a concept linked here, please do so in another topic. If you like you can then link to the comment here from your new comment. That way a link to your new comment shows up below the comment you linked to here, like below this one where it says Slow Chat.
Seen this before. This is a great series, fun and informati8ve, worth watching.
Update to where Iām at.
Co flow jet mods. Using basic materials, tools and equipment. Managed to come up with. As far I know nobody else has tried it. The only place that might have? was a nasa study into plasma injection for scramjet. That was to improve air flow at hypersonic speeds. Iām going for the assembly side. And making. Though thatās where I dip out on the high voltage knowledge. Arcing plasma something I still have much to learn on. Aware that it could have some advantages when it comes to blade designs? Or even solid lifting bodies? Still been trying to figure out what an old friend said once. About a whole aircraft power on a faradays cage. Not sure this is quite what he mentions. But its close. It still very much at the kit bash stage. It very rough around the edges. Plasma channel on YouTube mentioned something about the differential voltage from air to ground. With his corona motor.
Going as far back a the 1970s there been research into air breathing sub orbital ion thrusters. Much like a ramjet. Or scramjet. Yes I have thought about ion power scramjet. Have some ideas about increasing compression. Much like coronal discharges from the sun. Provide the airflow can be twisted repetitively. Then it could be done? As for the module. It may be a way of increasing pitch angles and keep laminar flow attached to the wing. As @PierreB mentioned on a previous post. Co flow jets get up to 70 degrees of pitch from take off. Before separation occurs. Now if the was a way to increase the angle? Considering that there still 20 degrees to play with. I say theres room for improvement target would be 80 degrees of pitch. Closer to 90 would be fantastic. It would test the limits of technology? To see if can maintain lift? So there we go the mornings offerings.

Optimising a VTOL
As Iām a broad spec guy I recently toyed with geodesic structures and their assembly. Using no more than electrical conduit and paracord. I made a pyramid, but no doubt there are other arrangements. Iām curious to know how this would work in a kite setting?
My first attempt at such structures. Im aware of the wide range of applications this could be used for across multiple sectors. Especially for those happy campers and wildlife lovers. As fore mentioned I was toying with the idea. it all reminds me of what @Rodread is doing with windswept and interesting.
This is just two triangles threaded together, then splayed. I Love the odd bit of gardening and construction. I donāt mind the odd freebie when offered. Iāve got enough to make a small dome if I wanted? Or all manner of projects? Clean film was going to be my next port of call.to cover it? it already been dismantled so That just how easy it is to make and disassemble. A few knots and some cord and your away. In the list of thing I had in mind, kayak, canoes, Coracle, domes and arches. Hides, cold frames, Poly tunnels to name but a few. Is suspect thereās more? Even a few awes applications long the lines of skin on frame construction.
I believe this might interest a few people here?
It a older post, I know thing can be missed while looking a different direction. Bullet proof chainmail? it apt as it the last day of battle abbey reenactment today. where William beats Harold and takes England for himself. I think he would have been impressed with this material, if he had it? Enjoy!
