Next up is the world’s smallest newspaper, which in case you didn’t realize, is placed next to the coffee cup!

The micro machine has a wheelbase of 80 mm (3.14 in), a seat height of 65 mm (2.55 in), weighs 1.1 kg (2.4 lb) and is powered to a top speed of 2 km/h (1.24 mph) by its 0.22 kW (0.3 hp) engine. The U-M team also developed a 48-stage Knudsen vacuum pump ( PDF). The Knudsen pump is unusual in that it has no moving parts. Instead, it works on the principle of thermal transpiration. If you connect two gas-containing chambers through a channel, the gas molecules will move between the two chambers until the pressure in the system is constant. If one of the chambers is now heated while the other remains at its original temperature, the pressure in the hot chamber will increase. Once these molecules of carbon monoxide were in place in each frame, the STM took 4 min 53 sec to scan the whole frame to build up the image recorded on film. This process was meticulously repeated for each frame. GTech are not exaggerating when it comes to this – the whole device could basically fit in a kitchen drawer! Having a lightweight vacuum is great for elderly people or those who have problems lifting normal vacuums up the stairs.If you compare that to other vacuums in their range, such as the GTech Power Floor and GTech Pro, the battery is less powerful. They each have 22 Volts. You can even hold it in one hand if you like…This means it’s ultra portable and easy to move around with. Additionally, they estimate the battery to last up to five years and say that it can be easily replaced. Does it actually last that long…? The HyLite uses a small amount of power, only 90 watts, but uses it very efficiently – the performance and suction power aren’t compromised in any way. The say a picture is worth a thousand words, but if you want to know exactly how small this wooden spoon is, it measures at just is 4.5 mm (0.18 in) long.

Simplified operation of a Knudsen pump that produces vacuum through thermal transpiration (Image: B. Dodson) At only 1.5kg (3.3 pounds), it’s definitely the lightest vacuum out there. Compared to other similar models, it’s noticeable that the HyLite is half the weight and still performs well.In October 2008 scientists announced they had discovered the first ecosystem on Earth which has only one species. The telescopic handle can easily be extended and retracted for your needs, and when you’re done you can detach it and put it away. We’ve seen the best features of the HyLite, but how do they translate into actual performance? Let’s take a closer look and see if the claims are true. To truly understand the benefits for the environment, we need to look at the power consumption of the device and the waste it produces, in this case, the bags. Power Consumption Every good vacuum cleaner needs a handy suite of attachments, even if they're tiny in size. The World's Smallest Vacuum comes with two interchangeable nozzles and a reusable filter that help you get the job done while keeping your vacuum cleaner running smoothly!

Contrary to recent trends, the GTech HyLite features a disposable rip resistant dust bag instead of a dirt container. This allows it to be even more lightweight as it doesn’t require additional filters. Alternatively, you can also leave it assembled as it is self-standing and won’t fall over. Lightest Vacuum According to GTech, the battery’s runtime is around 20 minutes on a single charge and takes around two hours to fully charge – a pretty fast charge compared to other brands. Usually lithium-ion batteries are pretty good so I wouldn’t be too concerned about it. What about the power vs other machines? Tom Wiberg (Sweden) built a motorcycle, which he named Smalltoe, that has a front wheel diameter of 16 mm (0.62 in) and a rear wheel diameter of 22 mm (0.86 in).Although it does have a slightly toy like appearance to it so you might be able to disguise it as one. It’s not to the same level as other vacuums, though, like the Dyson Animal V8. 2. Eco Battery
