The EU banned lightbulbs that suck more than 60 watts to improve the energy efficiency of an entire continent. And responding with the proverbial "F U" are two Germans, importing high-wattage bulbs and marketing them as heating devices called "heatballs."
The Onzo Smart Energy Kit sure looks handy, providing to-the-second energy usage updates from anywhere in the house. It's UK-only, but there's nothing about its wireless display that we couldn't (or shouldn't) do right here in the US of A.
James Watts spends his time putting together fantastic insect-bot sculptures, and the Solar Dragonfly is one of the best. The solar panels running down the body actually power the wings, which are then kicked into motion using a pager motor. Sure, it looks swell, but we can't help but think the Solar Dragonfly would…
