Lifting and moving objects using sonic tractor beams?

Well - not quite. It's basically using an array of micro speakers to support objects. Still interesting though.

How about tiny little nanomotors that gather up diluted CO2 and convert it to calcium carbonate?

Machines that are much smaller than the width of a human hair could one day help clean up carbon dioxide pollution in the oceans. Nanoengineers at the University of California, San Diego have designed enzyme-functionalized micromotors that rapidly zoom around in water, remove carbon dioxide, and convert it into a usable solid form.

The micromotors are essentially six-micrometer-long tubes that help rapidly convert carbon dioxide into calcium carbonate, a solid mineral found in eggshells, the shells of various marine organisms, calcium supplements, and cement. The micromotors have an outer polymer surface that holds the enzyme carbonic anhydrase. Calcium chloride, which is added to the water solutions, helps convert bicarbonate to calcium carbonate. The fast and continuous motion of the micromotors in solution makes the micromotors extremely efficient at removing carbon dioxide from water.

Now to perfect my 3D calcium carbonate printer and it's free JetSki time!
 
Thanks for posting that. :thumbsup:

Quite interesting and it does give me a sense of hope that mankind, despite the need for greed, will, at the very last possible moment, save itself from itself.

As well, I've thought from way back that nanotechnology was going to be a huge factor in how we live our lives in the near future.

Any updates on the warp drive thing that's not supposed to be able to propel stuff but it does in a lab?

still looking like it might be working after a 2nd round of tests
