Rocket radar?

DARPA's AtmoSense program seeks to use Earth's atmosphere as a global sensor by measuring acoustic and electromagnetic waves propagating through the atmosphere, and attempting to trace them back to a specific disturbance event that took place on Earth. In doing so, DARPA hopes to be able to trace underground explosions or other national security threats using the signals detected from the atmosphere.

Watch "Propellantless Propulsion Device | Charles Buhler" on YouTube

Dr Buhler thinks he has found a new force that allows for a a drive system that has no propellant. 

 

"Essentially, what we've discovered is that systems that contain an asymmetry in either electrostatic pressure or some kind of electrostatic divergent field can give a system of a center of mass a non-zero force component.

 "So, what that basically means is that there's some underlying physics that can essentially place force on an object should those two constraints be met."

Which is somewhere between an interesting theory and just using jargon to obfuscate. 

Personally, I'm learning toward this being hokum. But I am willing to keep an open mind and see if there's any merit to what he's saying.

Innovative new design in wind energy production

Spanish company, Vortex Bladeless Ltd., has designed turbines that are entirely without blades. They generate electricity by jiggling.

The structure of these bladeless turbines works by attracting whirlwinds. Depending on the speed and direction of the wind, these whirlwinds develop at certain frequencies. At the base of the bladeless turbine are two rings of repelling magnets. When the wind pulls the turbine in one direction, the magnets pull it in another, causing the tube to wiggle.

Energy reaches a peak when the frequency of the vortex or whirlwind coincides with the frequency of the turbine. This peak is established due to the aeroelastic coupling that arises at this point. It is at this moment that the energy is absorbed and converted from kinetic energy into electrical energy.

To simplify, the whirlwinds produced by the wind cause the turbine to vibrate. This kinetic energy is converted into electrical energy and used to power our homes.

Simple question

What is wrong with us?

An anonymous social media post tells a made up story about some college girl and it goes viral; the story even appeared on a national show. 

And then her life gets upended.

Rice and food scarcity

Here's another example of how the food supply is being disrupted by climate change. 

This is going to become the norm.

Elon 🖕🏼

You tried to buy an election, presumably for your own personal gain. 

But Wisconsiners? Wisconsinites? Aren't having it. 

Suck it. 

Here's to hoping they come after you for breaking the law, ya blatherskite 

April Fools

 

I was admittedly a bit of a prankster in college.  I perpetrated several different elaborate pranks just because, and on April Fools I tried to think "bigger."  

For several years running on April Fools, I would look for a free-standing newspaper machine (like the one pictured here).  I would switch 10 copies of the paper - 9 from the stack, and the one that was facing the world in the window - with ones from the previous year.  (this prank took some serious planning!).

I would then take the 10 current ones, and return home with them, and save them for the following year.

And for the record, since this was a prank, not a theft, I also carefully considered how to ensure everyone came out "even" on the deal.  I paid for the newspapers! (they only cost $.25 a the time, so I didn't see it as a big deal for a fun prank)
