Last week, hackers at the Black Hat conference showed how to jailbreak a Nest learning thermostat and override the firmware, taking it under their control.

The hack itself cannot be done without physical access to the device, and Nest said no thermostats have been hacked maliciously. But it’s one of many recent hacks of connected devices in the home. So how worried should people be?

In this podcast, we’ll talk about the widespread security implications for consumers, businesses and utilities.

Later in the show, we’ll ask if the Environmental Protection Agency is being transparent enough as it crafts carbon regulations. We’ll also look at the continued struggles for concentrating solar power and ask if there’s a future for the industry.
