  1. ahh, no, they pay less tax if they earn less – time to fix this then lol. Needleman estimates that lead exposure has already cut in half the number of U.S. children who might have had superior IQs (125 or over) — some 2 million kids. We have only begun to recognize what that may cost the nation in reading disabilities, high-school dropout rates and future economic competitiveness.

  2. at least in the old days it only made the super-rich and powerful more stupid – with the correction built in – like a natural balence

  3. Recycled fibers before more microfibers please. Clean up first then plan ahead.

  4. Recover Fiber is working on this. I like the fact that its a family of fibres that work with each other. Got to be the way ahead along with microbiological fibers of the future.

  5. You can make this beautiful version at instructables.

  6. Not entirely plastic bicycles, but you can buy replacement wheels made of plastic materials.

  7. Awesome concept! Check out this company that makes bicycles using plastic bottle caps. And the best part, you can return them to the factory to be recycled when they are too worn out. https://innovationorigins.com/en/startup-of-the-day-cycling-on-a-bicycle-made-of-used-plastic-bottle-caps/

  8. This, but it looks like that “is it a rabbit or a duck” puzzle.

  9. I’ve always wondered what it would look like if each square’s area was proportional to the element’s abundance on Earth, or the Cosmos. I am linking to this as although it isn’t it, it does give it a modern day twist.

  10. I didn’t realise we were 90% oxygen, carbon and hydrogen. So yeah, I like the idea of introducing kids to chemistry by telling them that is what they are made of.

  11. Cool. “Our biggest current challenge is embedding these smart sensors into a flexible and compliant material that can expand as the modules are inflated in space,” Kim says.

  12. Now that sounds like a good application for buckypaper. According to this it can be used as a lightweight heat shield that can stand up to the impact of hypersonic speeds.

  13. This would revolutionise things if it works and is cheap enough – not just on building roofs but on cars too.

  14. Jimbo

    This looks better “Quantum dots, also known as photovoltaic paint, were developed at the University of Toronto. They are nanoscale semiconductors that can capture light and turn it into an electric current.”

  15. could be more efficient than burning gas. Imaging that.

  16. read about this here…

  17. BUT…. The polymers of the future may not be made from monomers abundantly used today, but the polymers of the future may be degradable through a low energy process.

  18. Urr, this.,. AIR!

  19. “The Atomic Number 26 is formidable. If there are 26 Protons and 26 Neutrons in the Atomic Nucleus, there is a perfect Balance between exchange of Photons and Gluons. Nature has somehow chosen the number 26 to be unbreakable.”

    I got this quote from Quora. https://www.quora.com/Why-can-elements-heavier-than-iron-only-undergo-fission-whilst-elements-lighter-than-iron-can-only-undergo-fusion

  20. Wow, I so didn’t realise this was the case. So linking to where I landed when Googling it. On stack exchange, someone said this…

    “Iron is a “special” element because of its nuclear binding energy. The very basic idea is that when you fuse two light elements together, you get a heavier element plus energy. You can do this up to iron. Similarly, if you have a heavy element that undergoes fission and splits into two lighter elements, you also release energy. Down to iron. You can see this in the plot shown in the wiki article I linked. The physical reason for this has to do with the balance between nuclear forces and the electromagnetic force.

    Due to the way these energies work, and because iron is thus thought of as the most stable, if you want to get energy from fusion or fission, your best bet is to use atoms that are farthest away from iron — very light (like hydrogen) or very heavy (like uranium).

    As a side note, this is also why Type 2 supernovae happen — the star can no longer gain energy from fusion because it can’t fuse past iron, so the outward pressure from energy generation stops and the star collapses.”

  21. After dreaming one night about flexible sidewalks made of rubber and later seeing the interlocking rubber flooring at a health club, Richard Valeriano, who as a public works director in Santa Monica, came up with the idea of rubber sidewalks. But…

  22. Great idea and this was a thing years ago, why then never caught on I don’t know. maybe they pollute or break easily?

  23. Nitrogen no, but the age of Hydrogen-powered flight and spaceflight is dawning.

  24. this nitrogen idea keeps coming round, I don’t like it. here’s why:

  25. You are not alone with this idea. it needs work for sure…
