Nest Labs releases upgraded version of its Learning Thermostat

Apple fans with vivid imaginations love to dream up all kinds of fictional Apple products. iCars, iFridges, and iBoats may never see the light of day, but there is one home appliance that requires a bit less imagination. Former Apple exec Tony Fadell, who was instrumental in creating the iPod, brought his Cupertino schooling to the world of thermostats. The resulting original Nest thermostat was a hit, and – much like with an iPhone or iPad – its sequel is here, nearly a year later. Read More

World’s most efficient thermoelectric material developed

Approximately 90 percent of the world’s electricity is generated by heat energy. Unfortunately, electricity generation systems operate at around 30 to 40 percent efficiency, meaning around two thirds of the energy input is lost as waste heat. Despite this, the inefficiency of current thermoelectric materials that can convert waste heat to electricity has meant their commercial use has been limited. Now researchers have developed a thermoelectric material they claim is the best in the world at converting waste heat into electricity, potentially providing a practical way to capture some of the energy that is currently lost.

Superhydrophobic coating allows water to boil without bubbles

You know that thing that water does when it boils? The thing with the bubbles? Turns out, it doesn't really need to do that at all, with scientists finding a way to make boiling water a completely bubble-free zone. Researchers from Northwestern University, King Abdullah University of Science and Technology in Saudi Arabia and Melbourne University in Australia teamed up to prevent water from bubbling when it boils by using tiny spheres coated with a hydrophobic material.

HeatSeeker mister keeps firefighters cool

Firefighters face many dangers, including burns, smoke inhalation and structure collapses. Because they're required to wear all that heavy gear while performing strenuous activities, however, they also risk heat stroke. That’s why firefighter Michael Robinson invented the HeatSeeker – a device that attaches to a fire truck’s existing hose port, creating a cooling mist. Read More

Radiator Labs transforms radiators into energy-efficient heaters

Its idea may be simple, but that did not stop Radiator Labs winning the MIT Clean Energy Prize with its controllable box that can be retrofitted to radiators to boost the efficiency of hot water and steam heating systems. The heavily insulated housings physically cover the radiator, trapping heat in the system, and strictly controlling the amount that is let into the room. This prevents homes becoming over-heated, and wasteful heat loss as people open windows to compensate. Read More
