We love dinosaurs, but we never shared the planet with them. Such was not the case with woolly mammoths, which we once hunted, chowed down on, and used for tools and building materials. You don’t see T-Rexes on cave walls, but some of the earliest sculpture and art by human hands depicts these elephantine throw rugs.
Today, their well-preserved remains contain muscle, blood, teeth, bone, tusk and even brain. We’ve recovered and sequenced mammoth DNA, something we’ll never be able to do with dinosaurs. But if all you know about these majestic creatures comes from old Flintstones episodes, then join me as I explore …
Call it ecodriving, hypermiling or plain old frugality, people today are trying every trick they can think of to wring a few extra miles from a drop of gas. Unfortunately, most fuel-saving tips range from the dubious to the downright dimwitted. Even the ones that work — such as making only right turns — veer into the ridiculous. In this Top 5 list, I’ve separated the classics from the clunkers and saved you the trouble of doing your own Mythbusters episode. Read on to discover….
We tend to think of nanotechnology as the stuff of the future, but it’s already here, in hundreds of consumer products and industrial applications. As progress in this minuscule world has accelerated, concern for the environment and for public health has led to a call for green nanotechnology—approaches that accentuate the positive and eliminate the negative. In this article, we’ll take a tour of how these many approaches are playing out.
The world’s first mass-produced gasoline-electric hybrid car launched in December 1997 against a backdrop of growing concern over human-induced climate change and a clamor for greener technologies. Debate over the economic impact of the vehicles continues to this day, fueled by shifting sticker prices, ephemeral economic incentives and spiking fuel costs. Ultimately, detecting the economic impact of hybrids is about as easy as hearing an electric motor idling at a stop sign, but I took a crack at it anyway.
What was once a tenuous toe-dip into green waters for car companies looks more and more like a sea change. Manufacturers today are increasingly utilizing dual-mode drivetrains both to improve fuel economy and to make better performing cars, even as they avail themselves of the hybrid cachet to hawk them. Today, there’s a hybrid for nearly every palate and purpose.
