Airless & Bulletproof Tire. The Honeycomb

The military wanted an alternative to the current Humvee “run flat” tires, which despite the name, still need a minimal amount of air pressure to roll and can leave troops stranded after being shot or blown out. With this honeycomb tires, that’s all going to change. Aside from strength, the design allows shrapnel and high-caliber bullets to pass through the tire.

This is beyond awesome, and i would love to get my hand on these tires.

100 mph is the new Record of Fastest Bumper Car in the world

Bumper cars are designed to move about slowly. You need them to be engineered this way otherwise a bumper car ride would end with plenty of whiplash, tears, and probably some lawsuits.

So a bumper car ambles about with just enough speed so that you and some friends can gang up on another friend and pin them into a corner, while repeatedly taking turns smashing into them. Don't try and deny it. We know that's what you do.

The bumper car you're going to see right now, however, is a bit faster.

YouTube evil genius Colin Furze has teamed up with Top Gear to create a bumper car appropriate for the white-suited one. We're talking about the Stig, and we're talking about a bumper car with quite a bit more motivation under its skin.

Colin started with an old Dodgem bumper car shell. Then he added a 600-cc motorcycle engine which is good for 100 horsepower. That's quite a lot for something so small and light.

It's enough to propel the crazy craft down a runway at triple digit speeds. In fact, it's fast enough that it now wears the title of World's Fastest because a representative from Guinness was on hand to certify the runs. The Stig took the Dodgem down the strip running once in each direction. The average speed was just over 100 mph, and the wind-assisted speed was actually over 107 mph.

Now we know what Colin needs to do next. Build more of them, print up a bunch of waivers, and let us all have a go at the craziest game of bumper cars the world has ever seen. Wait. They already have that. It's called Demolition derby...

Bernoulli's principle

Bernoulli's principle can be applied to various types of fluid flow, resulting in various forms of Bernoulli's equation; there are different forms of Bernoulli's equation for different types of flow. The simple form of Bernoulli's equation is valid for incompressible flows

sweat in front of 6 of your friends in a tricycle

There is something confusing about seeing seven people sitting in a circle pedaling around a steering wheel to drive a tricycle. If you want to sweat in front of 6 of your friends you will have to pay the small sum of 20 000 €, which is more expensive than seven tricycles.


Radial engines are just plain cool – it’s inarguable that any tech that originated with early aviation is inherently awesome. But, what do you do when you want to build a radial engine in your dorm where a combustion engine would be inadvisable? For University of Washington students [Jeffrey Weng] and [Connor Lee] the answer was to power it with solenoids in place of the pistons.

The easiest way to approach a project like this would have been to use a microcontroller. A simple program running on an Arduino could have easily provided the timing to switch power to each solenoid in succession. [Jeffrey Weng] and [Connor Lee], however, took a much more interesting approach by controlling timing via a simple distributor. This works in the same way a spark distributor on a combustion engine would have worked, except it’s actually providing the power to actuate the solenoids instead of providing just an ignition spark.

Also impressive is what they were able to accomplish with such basic tools. Those of us who are lazy and have access to more expensive tools would have just 3D printed or CNC cut most of the parts. Either [Jeffrey Weng] and [Connor Lee] didn’t have access to these, or they wanted to increase their machining street cred, because they created all of the parts with simple tools like a band saw and drill press.

The “Farm From A Box” Delivers Modern Agriculture To Places That Need It

The Farm from a Box contains everything needed to run a small, off-the-grid farm: solar panels for power, water filtration equipment, pumps for irrigation, and decent tools. There’s even an onboard computer for land mapping and soil monitoring.

Developed in California, the box is an all-in-one kit designed to spread modern farming techniques to where they’re needed, whether that’s small plots of land in Africa or refugee camps in, well, lots of places these days.

“We want to develop this as a rapid response transitional food production system,” says Brandi DeCarli, co-founder of the Farm from a Box project. “The box is really infrastructure for places that are struggling with a lack of infrastructure.”

Most farms in the world are under one hectare in size, and many can’t be irrigated because they lack power. Solar power can allow farmers to use drip irrigation, which delivers small droplets of water and fertilizer to the base of plants. That means farmers are not dependent on rains: They can grow more food and more types of food.

Farm from a Box has a prototype installation in Sonoma, California, with another set to launch in Ethiopia’s Rift Valley early next year. Each will cost between $25,000-$45,000 depending on the level of technology inside. The most expensive versions will come with the mapping and sensing capabilities, while the lower-end ones will be more rudimentary.

DeCarli hopes to sell the box to the aid agencies or multinational companies as an alternative to distributing food. Giving local people the ability to farm could reduce the need for costly imports, she says. “It’s about being able to supply them with the tools to be able to grow and sustain reliable crops on their own.”

flying hovercrafts

If you don't want one of these flying hovercrafts then there's no other way to say this: you are lying.

Retail store Hammacher Schlemmer — which caters to all the needs of the wealthy gent — has begun selling The Flying Hovercraft. And as far as we can tell, this is the coolest vehicle money can buy.

The Flying Hovercraft not only glides over land and water, but it can also launch 6m into the air and travel short distances at speeds of up to 110km/h with the assistance of a pair of integrated wings.

The hovercraft's thrust is provided by a turbocharged 96kW two-cylinder petrol engine which drives a 152cm wood/carbon propeller for sea travel. For land and air commuting, the engine diverts its power to an 86cm lift fan. Two 40-litre petrol tanks give the craft a maximum range of 260km.

Contestants from the Biggest Loser need not apply though. The hovercraft’s passenger payload for flying is only 270kg.

The hovercraft is safe to operate in both fresh and saltwater and is also capable of traveling on sand, mud, grass, swamp, ice, and snow terrains with inclines of up to 30 percent.

The hovercraft’s pilot steers the vehicle via a joystick and uses a motorbike-style twist throttle for forwarding speed. A variable drive system allows the lift fan to enable hovering.

The craft does need to be registered as a boat, meaning you'll also require a boat license to operate one. There's no mention of a pilot's license being needed though.

The Flying Hovercraft is available now from Hammacher Schlemmer's online store for $190,000.
