Honeywell today summarily denied counterclaims in a patent infringement suit it filed against thermostat startup Nest Labs.

In a court filing, Honeywell stood by its claims that Nest infringed on its numerous patents in programmable thermostats. The suit was first filed against Nest in February.

Nest responded to the suit in April, saying that Honeywell's seemingly broad patents are "hopelessly invalid" and said Honeywell is trying to stifle innovation.

In today's filing, Honeywell fired back, saying the thermostat heavyweight intends to vigorously defend its intellectual property. The filing said Nest Labs' counter claims are "irrelevant … Read more

General Electric today introduced a 100-watt equivalent LED bulb which is the clearest example yet of how high-tech lighting has become.

The company's Energy Smart LED bulb consumes 27 watts to give off the same amount of light as a 100-watt incandescent lamp. It will be released in the first half of next year. The price has not yet been set.

GE's announcement, made at the Light Fair industry conference in Las Vegas, shows how lighting manufacturers have finally cracked one of the toughest challenges in LED lighting -- making lamps able to give off a lot of … Read more

For centuries, the people of Tokyo have been flocking to the Sumida River to see fireworks displays. This past weekend, though, they got a spectacle of a different sort as thousands of electric "fireflies" wafted downstream.

The Tokyo Hotaru Festival 2012 is a modern twist on the age-old Japanese love of watching fireflies along waterways. Some 100,000 blue LED light bulbs floated down the Sumida in imitation of the insects, long celebrated in haiku and other verse.

Measuring just over 3 inches across, the LED bulbs were charged with solar-generated electricity and later reclaimed in nets downstream. … Read more

Philips this fall will release an LED bulb as bright as a 100-watt incandescent lamp, filling out its existing LED line.

The company will add to its EnduraLED line with a lamp that gives off almost 1,700 lumens, or about the amount of light as a 100-watt incandescent, and consumes 23 watts. The product will be available this fall. Philips did not disclose the price but it is expected to be in the $40 to $50 range.

This latest EnduraLED has a color temperature is a warm yellow at 2,700 Kelvin, is dimmable, and has a color rendering … Read more

Automakers have endorsed a connector to charge electric vehicles in as little as 15 to 20 minutes, a technology which promises to make public charging stations more compelling.

German and U.S. automakers Audi, BMW, Chrysler, Ford, General Motors, Porsche, and Volkswagen yesterday issued a statement saying they will support the same charging interface.

Called the Combined Charging System, the standard can charge electric vehicle batteries with alternating current from a home outlet, direct current from a home outlet, or "ultra-fast" direct current from public stations. The system will be demonstrated next week at the International Electric Vehicle … Read more

Greenpeace has uncovered documents that the group claims indicate Apple has plans to draw more power at its North Carolina data center than it has stated.

The environmental watchdog group yesterday published a permit application and permit for back up diesel-powered generators at Apple's Maiden, N.C., data center that's now under construction.

The documents indicate that Apple requested and was approved to use significantly more than the 20 megawatts of power Apple projects its data center to use at full capacity. The company received environmental permits to install 54 megawatts of diesel back up power, but because … Read more

Logitech's been on a roll with its well-made keyboard accessories for the iPad (the Ultrathin Keyboard Cover is one of my favorites), but there's one big problem with all these accessories: they need their own USB charging cables.

Logitech's just-announced Solar Keyboard Folio adds a clever twist to the crowded iPad keyboard case market by introducing a solar charger. Better yet, the case doesn't look clunky.… Read more

It's time for your DVR to get as smart as your iPad. If designers get it right, energy use from household electronics will stay under control without sacrifices in features.

By necessity, mobile devices, such as tablets and smart phones, need to be clever about power, just like an efficient hybrid car uses many tricks, such as turning the engine off when idle, to sip less gas.

By contrast, always-on electronics devices, such as set-top boxes, DVRs or often game consoles, operate as if they were going top speed at all times. As more devices in the home, such … Read more

What would you do for free Wi-Fi? Mexican Internet provider Terra has teamed up with ad agency DDB to offer free Wi-Fi in public parks to dog owners who clean up after their pets.

As seen in the absurd promo vid below, owners who deposit poop in the special bins in 10 parks in Mexico City will be rewarded with free Wi-Fi, broadcast through routers shaped like doggy bones.

The more you add, the more minutes you and everyone else gets. The bins seem to have a simple scale to weigh the poop, so they would likely still work if people put rocks or trash in them instead. … Read more
