Energy from the air? How very Tesla of you! But unlike America's favorite quirky inventor, this isn't transmitted power and no dogs have to die. It's using moisture from the air - and the more humidity you have the better.
Similar to the way solar cells capture sunlight, hygroelectric collectors would collect moisture and use it to light a house or recharge an electric car. Bonus: Panels on the rooftops of buildings could prevent lightning strikes - and the technology is already in the early stages of development.
Are you a brilliant student but can't take tests well? A star athlete in practice but nerves overwhelm you at game time? It's common but in varying degrees; the line between someone who worries about performance and therefore does even better and someone who 'chokes' under pressure is fuzzy.
Did Neanderthals develop `modern' tools and ornaments solely through contact with Homo sapiens, or could they adapt, innovate and evolve technology on their own?
A new anthropology study challenges a half-century of conventional wisdom that Neanderthals were primitive `cavemen' overrun and out-competed by modern humans arriving in Europe from Africa.
Airlines, hotel companies, anything with a date attached, know they have you on the hook the closer to that date because no one buys airline tickets for tomorrow unless they are desperate, and there are fewer tickets available, so capitalism says you consumers will pay more because they must.
But even William Shatner knows the airline seat or hotel room has no value for the corporation either, once it is gone - he works for a corporation that makes money selling last-minute fares and hotel rooms because it is an asset that expires. That can be your advantage also because airlines and others don't want to fly empty so they often have the 'best' prices on a limited number of seats long in advance in order to break even. Buying in advance makes sense also.
The United States is home to some 40 different species of bat. Thanks to stories of blood-sucking vampire bats, they've somewhat developed the reputation of a fearsome pest, but in fact they are a vital part of our local environment. Many bats can eat their body weight in insects on a single nightly outing. As such they play a huge role in controlling local populations of real pests: disease-spreading insects.
But across the country something devastating is happening, more than a million bats have now been wiped out due to the rampant spread of a fungal infection known as White Nose Syndrome (WNS).
