A new type of cement mixes Titanium with the usual lime / alumina compound and heats it up to 1100 degrees Celsius. The resulting compound conducts electricity about as well as other metals at room temperature.
With Titanium in the mix, don’t expect to see this mix in your every day concrete pour. The article mentions a possible application as a substitute material for Indium which is used in plasma TVs and the like. This material is going to find a home inside of an iPod or cell phone probably.
All in all, it reminds me of electrically conducting clay polymers but with the novelty of being made with portland cement.

One of my favorite authors is drumming up publicity for his upcoming book by giving away the book…again. Yeah, I know how that sounds, but it worked for Cory Doctorow, so it not totally off base. Scott Sigler has podcasted Ancestor as a podiobook to over 30,000 fans and has now released a free PDF of the entire book again. If you like action oriented sci-fi with “Lots and lots of violence”, this is just the thing for you.
