Voyager has hit interstellar space…. maybe?

by Gabriel in Lunatic Laboratories

Poor Voyager, he just can’t catch a break. We’ve said it’s hit interstellar space more times than we want to admit and in 2012, the Voyager mission team announced that […]... Read more »

Optical Cables, from Thin Air!

by Gabriel in Lunatic Laboratories

It’s a project that would make Tesla proud. Just imagine being able to instantaneously run an optical cable or fiber to any point on earth, or even into space. That’s what researchers are trying to do. Did I mention it was instantaneous and involved no connection other than the air around us? Well if you are as excited as I am, then you should read on! If not, two words, laser weapons!!... Read more »

Do quarks grant confinement?

by Marco Frasca in The Gauge Connection

In 2010 I went to Ghent in Belgium for a very nice Conference on QCD. My contribution was accepted and I had the chance to describe my view about this matter. The result was this contribution to the proceedings. The content of this paper was really revolutionary at that time as my view about Yang-Mills […]... Read more »

Laser Helps Understand Inner Workings of Solar Panels

by dailyfusion in The Daily Fusion

Finally, a better Battery!

by Gabriel in Lunatic Laboratories

You know what technology hasn’t been able to keep pace with us? Well besides whatever tech the DMV uses, it’s batteries. Think about it, they are nasty, make a mess, are hazzardous, hard to recycle and weigh a freaking ton compared to the energy stored. Current battery technology is my number one problem with electric cars as it stands now. Between the weight, the resources, and the waste, electric cars are almost a wash. Not quite mind you, but almost.... Read more »
