On raw material there is a limit to cap down the price. only the production, logistics, retail, margin, sales can be cheaper.
But what if the raw material production consumes more energy than the product generates in its lifetime? Like solar panel silicon wafers?
Probably still depends on the scale and usecase, too.
OK if you look for a portable or temporary off grid solution, but production and maintenance over (short) lifetime might cost much more energy than it generates, so it doesnt make sense except for this special mentioned usecase. You def. will not save the world with these unefficient devices. And I doubt that it's physically possble to make them more durable and efficient in the near future.
Same to portable solar panels.
Though the whole graphene research sounds promising.
Take into account efficiency, maintenance and material fatigue, which is a big issue on vibrating devices.
physics behind wind turbines is obviously anything but trivial
there are strong forces, streams and vibrations, some of which counteract or reinforce each other. If the material of the system components is taken into account, it becomes even more complicated
the more blades the less efficient
With 700k you can buy 7.5, not 10 right now.
Is this the floating wind turbine nostr:nprofile1qqs8wakr9493685t725kh2ltgwke4hs400fk8kymslak8eh3g42c3zqppemhxue69uhkummn9ekx7mp0qyvhwumn8ghj7urjv4kkjatd9ec8y6tdv9kzumn9wshsz9thwden5te0wfjkccte9ejxzmt4wvhxjme03x0ggy talked about?
I lost all my coins in a boat accident, so 0% unfortunately
No you didn't ๐ But it s OK.
We listen and don't judge.๐ซ๐
You're the most entitled troll I've seen so far.
You get another ๐ for that.๐
