Opinion: Over the weekend, we learned that an Abbott government directive has banned any more investment in wind farms by the Clean Energy Finance Corporation, a government body that encourages investment in the renewable energy sector.

It may not be as pretty as the Powerwall, but it does the same job. It’s currently undergoing trials, so the full details are not yet available, but we crunched the numbers based on what we know so far.


CSIRO App Controls Your Appliances, Measures Individual Power Usage

Smart meters have taken us a step closer to “digitising” our power usage and making it easier to monitor just how much electricity we’re using. CSIRO however is taking the concept further and in conjunction with app developer HabiDapt, is trialling software that will allow you to see the current power consumption of individual household appliances, along with a breakdown of usage costs, with the ability to turn them on and off remotely.


Watch An Awesome Lightning Bolt Get Captured In A Box

What we’re seeing is Lichtenberg Figures form from an electron beam getting zapped into an acrylic prism. The electric trail of the lightning strike is so badass. It’s like trapping a lightning bolt in a glass box forever, a force of nature on display.
