This is the first vacuum cleaner, the 1905 Skinner Vacuum, from the Hoover Company. And this one weighed 92 pounds and took two people to operate and cost a quarter of a car.

Oasis is a meteorite crater in Libya.

This was truly, truly an early adopter product the 1905 Skinner Vacuum.

Living on a Volcano

Neith crater is a crater on Jupiter's moon Ganymede, the largest moon in the solar system.

They are built by ejecta from a volcanic vent, piling up around the vent in the shape of a cone with a central crater.

Electrons have an electric charge, a negative one, and quarks have electric charges in thirds.

It is a fresh crater with a distinctive central peak.

He owns an electric Tesla Roadster, a Fisker Karma plug in hybrid, and a Toyota Prius.

Later, a large crater on the Moon was named in his honor.

A maar is a broad, low relief volcanic crater that is caused by a phreatomagmatic eruption i.e., an explosion caused by groundwater coming into contact with hot lava or magma.

People want freedom, but not when it comes from the barrel of a US gun.

The only exception is Ursula, which has a pit in the center.

There is a median point between tiny rock and gigantic rock, and in fact, if any of you have ever been to near Winslow, Arizona, there is a crater in the desert there that is so iconic that it is actually called Meteor Crater.

For each wrong answer, the candidate is given an electrical shock.

The aircraft also had heating and electrical lighting.

Muzzle velocity is the speed a projectile has at the moment it leaves the muzzle of the gun.

Thomas Thwaites How I built a toaster from scratch

And my day job, as Chris said, I'm an electrical engineering professor.

When first erupted from a volcanic vent, lava is a liquid at temperatures from .

Every time you contract a muscle, it emits a little electricity that you can record with antennae or electrodes and use that to operate the motorized prosthesis.

The purpose was to make a crater to excavate the material and see what was underneath the surface of this comet, which we learned quite a bit about.

Rooms in leading hotels may have 110 volt outlets.

Some of the Kjeller aircraft had not been fitted with machine guns, and those that had been fitted still lacked gun sights.

It's called Pavlovian fear conditioning where a tone ends with a brief shock.

It's not just making about it's making self assembled cell phones and circuits.

In the 1950s, Olds and Milner put electrodes into the brain of a rat.

He felt the coldness and didn t like it, so he poked me with an electrical prod.

One notable example right before the launch, SpaceX engineers found a few cracks in the second stage engine nozzle extension.

The crater diameters range from a few kilometers at the low end to 326 kilometers for the largest known crater, Gertrude.

But the electron also has a neutral partner called the neutrino, with no electric charge and a very tiny mass.

I mentioned automobiles buy a hybrid. Use light rail.

The wind farms that we built convert the wind s kinetic energy into electricity.

Thus, there is an enormous potential for producing surplus electric energy in a sugar plant.

The nozzle of an arc pistol should never be viewed directly, unless it is certain that no power is available to the equipment.

The other part of the virus has a sequence that can grow an electrode material for a battery.

We looked at an MIT study ten million electric cars on the global roads.

This fluid, which has a high electrical conductivity, is sometimes called a water ammonia ocean.

So I thought, okay, I'll try and make an electric toaster from scratch.

But if you don't have grid supplied electricity, then the whole question of payback is a different one entirely.

That s considerably less than the cost of a new car especially an electric one.

In September 2010, a sculpture of three giant light bulbs was erected in Brno, in front of the theatre.

It is part of the first generation of matter, has an electric charge of e and a bare mass of 1.8 .

It is part of the first generation of matter, has an electric charge of e and a bare mass of .

He also supposed that chemical reactions could occur when two atoms share an electrical charge.
