Living in the Midwest, where heating homes with propane is common, I periodically see reports in the local paper that yet another unoccupied house has exploded. They often note that the roof was found in the basement, while the walls were spread some distance into the neighboring fields.
If you plan on insulting your romantic partner’s style sensibilities, then by all means, buy her a pepto-pink gizmo. After all, nothing says those three magic words (by which I mean, “Let’s break up!,”) with quite the same punch as does a blushing gadget. If, however, you want to say those other three words that are the entire reason for February 14th, read on for some gift ideas that are sure to make her squeal with joy. Set the mood with a few LED candles, spruce up the apartment with some love-centric aromas, make sure your breath is kissably fresh, put some romantic tunes on (bonus: give her the flash drive to keep!) and wow your geeky gal with one of the following Valentine’s Day gifts.
As you huddle inside your home this winter cursing the gloomy darkness, remember that you’re not alone: The season has an even worse effect on your plants. Many common houseplants need far more hours of light than they get naturally in the middle of February, especially if they don’t have direct exposure to a sunlit window. Although the incandescent and fluorescent bulbs most people have in their homes will keep plants alive, they don’t emit light that’s within the temperature range necessary for optimal, or even adequate, foliage growth in light-hungry plants.
A good dose of nature can still soothe the psyche of the modern human, but sometimes nature, red in tooth and claw, can also just gross you out. Wasps turn helpless caterpillars into a 24x7 buffet for young ones, mama mantis snacks on the head of its former lover, and a frog gives new meaning to oral fixation when nurturing the kiddies.
Not necessarily. It’s hard to ignore MS Office, but you don’t need to blow 400 bucks to get your work done. In fact, you don’t need to install any programs at all. Sign up for the free Google Docs (documents.google.com) or Zoho (zoho.com), and you can do everything in a Web browser. The programs look similar to Word, Excel and PowerPoint and offer all the same features (save for a few lesser-used ones like certain spreadsheet formulas). Zoho even kicks in a few extra applets like a Wiki-building tool. Best of all, these applications let you access your files from any computer that’s online. If you don’t have reliable Internet access or are more comfortable installing programs on your computer, there’s no shortage of competition, either.
Sky Serpent Cost to Develop: $250,000 Time: 9 years Prototype | | | | | Product Today’s largest wind farms are the size of small towns, made up of turbines 30 stories tall with blades the size of 747 wings. Those behemoths produce a great deal of power, but manufacturing, transporting, and installing them is both expensive and difficult, and back orders are common as the industry grows by more than 40 percent a year. The solution, says inventor Doug Selsam, is to think smaller: Capture more power with less material by putting 2, 10, someday dozens of smaller rotors on the same shaft linked to the same generator.
Perusing the deluge of overheated press releases from the CES conference a few weeks ago, one in particular, for Panasonics new line of EVOLTA batteries, got me thinking. And when I say thinking, I mean muttering curse words and shaking my fist. The release made a big deal about the fact that these new batteries last from 1.3 to 2 times as long as other alkaline batteries—which is to say, slightly less poisonous and wasteful, but not much. Whoopdee-flipping-doo.
If you've tinkered with bikes in the last decade or so, chances are that sheldonbrown.com has proven incredibly useful to you—it's practically the Bible of bicycle mechanics, repair, maintenance and appreciation on the Web. I was saddened to read today that its keeper and one of the online cycling world's most charismatic presences passed away on Sunday of a heart attack.
