carbon nanotubes. The ubiquitously researched microscopic tubes can conduct electricity far better than metals, due to their "ballistic conductivity," a property where no electrons are dispersed or blocked. But, the problem with carbon nanotubes, as CNET reports, is that they're really tough to mass produce; once created, some act as great semiconductors, while others don't. So now, Intel has to figure out how to get carbon nanotubes to act more uniformly, or to separate the bad ones from the good. Thankfully, consumers won't have to worry about this problem for about another decade, which is why Intel has brainiacs working on a solution as we speak.
