Another helium-filled post - this time it's a helium-filled blimp that houses a horizontal-axis wind turbine [source: gizmag]. Altaeros Energies recently released a video of their prototype Airborne Wind Turbine in action:

Who knew that tetrahedra could fly? I know, pretty much anything can fly when you fill it with helium, but the movement of helium-filled tetrahedra called SmartInversion by Festo gives rise to an interesting and unusual propulsion method [source: gizmag]. Using inverse kinetics, Festo have developed what they call an "airborne geometrical band with inversion drive". The movement is difficult to describe but mesmerizing to watch:

Fishermen at Lake Como, Italy, have shown remarkable knowledge of the complex water currents in the lake. Researchers found [source: Science Mag] that the fishermen's knowledge correlated well with independent observations and Computational Fluid Dynamics (CFD) simulations. The primary means the fishermen use to monitor water currents is by the deformations the currents cause in their large nets once deployed in the lake.

Big news from Europe - a new European directive has just been passed that requires all software applications released in the European Union to support the Esperanto language by June 2012. This is part of a larger European directive mandating that all European countries are to adopt Esperanto as the Europe-wide common language by 2014.

Do you sometimes feel like your Computational Fluid Dynamics (CFD) simulation just needs a little nudge to do the right thing? Well I'm sure you'll appreciate (need even!) some light relief with the fluid-based video game Puddle. Puddle is all about nudging and manipulating the world so your precious fluid gets to its destination through a fiendish puzzle-like maze.

Any fluid dynamicists out there searching for just the right wrist watch? Well the search is over, check out the HYT H1 [source: Gizmodo] fluid-themed watch from "The Hydro Mechanical Horologists" - try saying that after too much fluid!

Going fast and aerodynamics are intimately related, whether it's for a Formula 1 car or in this case for a remote control (RC) car. The Traxxas XO-1 is billed as "The World's Fastest Ready-To-Race Supercar" with a 0-100 mph time of under 5 seconds. More interesting than its out-and-out straight-line speed is that this RC car employs advanced aerodynamics for generating downforce.
