The resulting visual effect – that of walking on air – is really something else. But how did this clear ice come to be?

Solar cell efficiency is nearing 50%. Australian scientists have set a new record by converting more

Solar cell efficiency is nearing 50%. Australian scientists have set a new record by converting more than 40% of sunlight that hits solar panels into electricity. These panels could eventually be mounted on roofs, which current have a 15-18% efficiency rate. And in Germany, scientists converted 46% of light into electricity in a lab, a new record for PVC efficiency.

Nobody likes those overages Data caps seem to have become the norm in the cellular industry. Sure, you can find a carrier who lets you eat as much data as you want, but most carriers and plans have a limit of some sort. We don’t like it anymore than you do, but we’ll leave that for another discussion. This time around, let’s take a peek at a new quick shortcut to see just how much data…
