i dont know how useful this is to anyone?
i just thought id drop a link?
robert murray smith been busy?
reminded of this?
if this is useful? have a crack at it?

nice, this is but one example of ground effect vehicles that ive seen. depend on the terminology? but GEVâs is another name for them that normally includes a broader range of vehicle types? which can include hovercrafts? id love to know if AWEs is developing one for power generation?

ekranoplano
I hear there Chinese are currently developing one as a troop transport? which has the usa on the jitters because of Ukraine and the island in the pacific it still patrols? ive been in awe of these craft ever since in known about them? also forms a basic to back to the future style hoverboard? mcflyâs ride over water was probably ground effect? couple with a few other fancy things?

Easy Graphene Production With A Laser Engraver | Hackaday
came across this realising the practical application for it. knowing you guys always are look for new fin and exciting techniques to use and love to save a bit of money along the way?
it is my understand that there is work out there of next gen solar cell using graphene? supposedly can work at night? depending on how it made? broad spectrum solar panel? able to work in both the infered and ultraviolet end of the spectrum. even hear the possibility of it working on cosmic microwave background radiation? it also mean you could have whole kite skins that are fully solar and multi functional?
I shall leave this here for the curious?
My experience indicates steel is great, but obviously heavy. Carbon fiber has good strength and stiffness for its weight. Fiberglass is floppy and heavier than carbon fiber. Of course this is not really new information⊠Carbon fiber is a condiuctor. Lightning? Also, you donât want carbon fiber in long-term contact with aluminum. There is a galvanic reaction that can occur, not unlike that with dissimilar metals.

Pretty funny when he wants to put the props overhead to get more stability [it does not affect stability]. Sadly though his next movie may well turn out to be a snuff movie.
One point is made clear though, that quad would certainly use a lot more fuel per kilometer compared to most other ways of transport. So maybe it will turn out people actually dont want to spend that amount of cash to escape the ground
The pendulum rocket fallacy. This is a nice picture to illustrate it: Rocket - Wikipedia And here is a Tom Stanton explainer: https://www.youtube.com/watch?v=OYHCP3-mpxk
Letâs hope he figures it out or someone tells him.
I posted the video because it is more than an hour of a person clearly skilled in fabricating, fabricating a thing, and showing you many different techniques you can use in your own garage along the way. If you wanted to make your own propellers in your garage, he shows you one way to do that for example.
A tour of a hardware startup, talking about the iterative testing that they do. It also shows some innovative manufacturing methods. Starting at this time stamp for example it starts talking about incremental sheet forming (roboforming).

Towards the end an explanation of button technology; using a marble, rope, and a taut-line hitch to make the marble into a button, or attaching the rope to the fabric, without having to puncture the fabric, so keeping its strength and water resistance.
