NASA’s new robotic vision – Windbots !

Engineers at JPL (Jet Propulsion Laboratory) are working on a new class of robotic probe designed to stay aloft for a long time without wings or hot-air balloons in atmospheres of giant planets. There is no shortage of something different, challenging & cool things at NASA & we know that very well.…

How Rocket Engines cooling system work ?

Our heavenly Internal Combustion Engines used in cars & bikes can be cooled by air & water or coolant circulating around it. But what about rocket engines ? How rocket engines cooling system works ? The engines of rocket heat up upto 6000°C. At this temperature the metals would become…

How does Geneva drive mechanism works ?

The Geneva drive or Maltese cross is a gear mechanism that translates a continuous rotation into an intermittent rotary motion. The rotating drive wheel has a pin that reaches into a slot of the driven wheel advancing it by one step. The drive wheel also has a raised circular blocking…

Banana Arduino !

yea… we all love CURVES, ahem-ahem… yaa ok, concentrate here, I am saying in terms of design. Well, now have seen thousands of circuit boards have the same geometrical shapes – square & the rectangle ones. So here comes the oddly banana shaped Arduino. It’s maker says that it will…

Boeing’s new laser powered fusion-fission jet engine

Get ready, for this highly UNREALISTIC jet engine… Boeing has received a patent, US 9068562, which combines inertial confinement fusion, fission, and a turbine that generates electricity. Currently this kind of engine is completely unrealistic given our mastery of fusion. But perhaps in future this might be an excellent idea.  …

Working of a Differential

Introduction:- In my previous article we saw about how trains turn on curved tracks. Well in automobiles, we can’t use the same principle for turning around a corner as our cars don’t run on tracks. So we cannot design our tires as the train wheels. At the beginning of auto industry,…

Cubli-“Auto-jump,balance,walk”

Cubli-A combination of two words, Cube- an English word & li- an Swiss German diminutive word meaning ”small”. Researchers from the ETH Zurich’s Institute for Dynamic Systems and Control have developed the Cubli, a 15x15x15 cm device that can walk, jump, and balance itself on its edge or even on a…

How do trains turn without differential ?

We have travelled thousands of kilometers in trains, but we haven’t given a thought about how do trains turn during a curved path ? Both the wheels are connected through an axle & obviously are of same diameter. But,when a train takes turn, the outer wheel has to cover more…
