Sailing just might be the key to the future of efficient ocean travel.
The pharmacy chain has just announced plans to build the first retail store in the US powered entirely by onsite energy sources.
They say that everything is bigger in Texas. This giant new battery pounds that point home, by storing enough juice to power 17,000 homes.
A new proposal from GE could upgrade wind turbines, replacing traditional blades with technology that would seem familiar to a World War I fighter pilot.
We know that there's more than enough wind energy out there to power our entire civilization, but conventional wind turbines don't do that great of a job of harnessing it. They're expensive and inefficient, and we're looking for better technologies, one of which is a super efficient wind turbine that doesn't need blades.
Wind energy is some of the cleanest energy there is. It's relatively cheap to produce and easy to install, and produces power fairly reliably. So, but what happens if we transition to nothing but wind power? As dumb as it sounds, will we run out of wind? The answer seems to be "probably not," but there will be consequences.
Traditional wind turbine designs are HAWT. You know, not hot hawt, but HAWT like a Horizontal Axis Wind Turbine." A HAWT design is what you probably think of when you picture a wind turbine (it's the thing that looks like a big propeller on a stick), but the next generation designs may be all about the VAWT, not the HAWT.
Bigger wind turbines generate more power, but you can get just as much power by using a bunch of smaller wind turbines. The question is, which way do you go if you want to produce more power while staying as environmentally friendly as possible? We totally gave it away in the hed, but the scaling is such that truly gigantic turbines are an inevitability.
A study published this week in the journal Nature Climate provides evidence that wind farms are responsible for localized temperature increases of up to 0.72 degree per decade. While some people equate this with wind farms "causing" global warming, the reality is that just about everything humans do to our environment causes climate change.
Trials have just been finished on a new kind of wind turbine — an inflated, helium shell containing traditional blades that floats in the air stream. The airborne turbine is designed to capture stronger, high-altitude winds to provide a clean, portable and power energy option.
