Ionic cooling system melts and freezes material to cycle temperature

Heating and cooling systems are among the biggest guzzlers of energy, contributing to a vicious cycle of climate change that then drives higher use of heating and cooling. Now engineers at Berkeley Lab have developed a new technology that heats and coo… Continue reading Ionic cooling system melts and freezes material to cycle temperature

Solid-state refrigerant works under pressure for greener cooling

As useful as refrigerators and air conditioners are, the gases they use as refrigerants can leak into the atmosphere and become major contributors to climate change. Now engineers at Harvard have demonstrated a new prototype cooling device that uses a … Continue reading Solid-state refrigerant works under pressure for greener cooling

World’s first liquid-nitrogen outdoor cooling system set for trials

Israeli company Green Kinoko is preparing for the first public tests of a remarkable clean outdoor cooling system. The Kinsho system operates like the inverse of an outdoor cafe heater, cooling several tables per unit without using any electricity.Cont… Continue reading World’s first liquid-nitrogen outdoor cooling system set for trials

Super-efficient linear compressor could vastly reduce air con power use

Compressor efficiency might not sound like the most exciting topic in the world, but consider this: the hotter the world gets – and the wealthier its developing countries become – the more air conditioners will come online. According to the IEA, fans a… Continue reading Super-efficient linear compressor could vastly reduce air con power use

“Cold Tube” cooling system uses half the energy of an air conditioner

Air conditioners are a convenient way to cool down offices and homes, but they use huge amounts of energy in the process. A team of scientists has been developing an alternative solution for those warm summer months called the Cold Tube, which works by… Continue reading “Cold Tube” cooling system uses half the energy of an air conditioner

Sony is crowdfunding a wearable air conditioner for personal climate control

For those times when the outdoors is too hot or too cold, the easiest way to find respite is to dash inside. But what if that’s not an option? Sony thinks it has the answer with the Reon Pocket air conditioner, which it’s crowdfunding through… Continue reading Sony is crowdfunding a wearable air conditioner for personal climate control

BlackIoT Botnet: Can Water Heaters, Washers Bring Down the Power Grid?

In testing, an Internet of Things (IoT) botnet of large, power-consuming appliances was used to carry out coordinated attacks on the energy grid. Continue reading BlackIoT Botnet: Can Water Heaters, Washers Bring Down the Power Grid?

Repost: Hacking the power grid through air conditioners

This is a repost of a blog that Joe Marshall (@ImmortanJo3) and I wrote on February 22, 2016 and @da_667 posted to his blog (which is now defunct, but he has given me permission to post here). It’s not that easy.. Ladies and gentlemen, … Continue reading Repost: Hacking the power grid through air conditioners
