Energy News: Boring LEDs, Exciting Magnets, and More

holding-LED-light-emitting-diode LEDs are “boring”

Has LED lighting become blasé? Some think so and say it’s a good thing. They argue that the more that LED lighting becomes a part of consumer consciousness, the more available and cheaper it will become. Which is a good thing, since incandescents are going the way of the Dodo, the dinosaur, and Zubaz pants.

Is there anything magnets can’t do?

The United States Navy is developing a new technology that regulates the flow of electricity to light sources, as well as capturing residual magnetic energy and redirecting it back into the lighting. The Navy reports that the technology worked swimmingly in tests on a base in Tokyo, Japan, and leaves us all aflutter with thoughts of applications for this technology in the civilian world, as it could cut lighting energy use by up to 40 percent!

Better than hibernation

Well, it’s a sad fact, but we here in the northern hemisphere are headed into the colder months, which means warmer clothes, hot chocolate, and weatherization! Weatherization? Yes! Jetson Green has a how-to guide to weatherize your home for fall so that you won’t be paying out the nose for heating.

The wheel of progress keeps turning

Inhabitat recently posted a list of six amazing eco-innovations, such as a transparent spray that turns windows into solar panels, a shoe that generates electricity from walking, and a science campus in Switzerland that harnesses summer heat to warm buildings during the winter!

Save energy...running away from bears

We’ve written about saving water in your garden, but what about your garden saving you? A woman in Montana reportedly fended off a bear attack that sounded pretty grisly (see what I did there?) by hitting the beast with a homegrown zucchini.

    but wouldn't using magic maginets to drag power from radio signals - WiFi, Bluetooth, TV, DECT etc - simply mean those transmitting the signal have to up their power in order to maintain the same throughput on the signal?

    kinda self defeating as unless the extraction is 100% efficient it would need more power to be put in than can be extracted, and the increase in radiated power has more potential for harming bystanders...
