Japan aims to develop ultrafast wireless technology by 2020
Japan is aiming to develop a super-fast wireless system by the 2020 Tokyo Games that would allow a smartphone user to download three high-definition movies in one second, an official said Friday.
The technology, which is still in its early stages, would use wireless semiconductors, the official of the Internal Affairs and Communications Ministry told AFP.
“The chips would use very high frequency bands, called terahertz signals, which could move data at a rate of 100 GB per second. And that would be as fast as downloading three movies in a second,” he said.
The ministry wants the technology in place in time for the Tokyo Olympics, he said, adding subcontractors would be recruited to take on the research.
Satechi Portable Humidifier Turns Any Water Bottle into a Humidifier
It’s made for dorm rooms but we think that understates the usefulness of repurposing any water bottle with the USB-powered Amazing Humidifier. It’d be great for making any personal space less stuffy.
When you think of a humidifier, you probably picture a fairly large device filled with water that you plug in and keep in a corner. Those traditional options don't work so well when you need to move them around and require a bit of effort to clean. The Satechi Portable USB Humidifier just attaches to any water bottle and gets power from any USB port of charger.
If you need to add humidity to a large space, you'll need something a little more powerful than a portable option. If you just need a little humidity in your part of the room, however, you can set a water bottle by your bedside or wherever you are. If you move, you can take it with you. If you can't be tethered to an outlet or a computer's USB port, get a portable battery.(Ideally, we'd like to see a version of this device that contains its own battery to operate on the go for a few hours, but generally speaking you won't need that.) Most humidifiers cost at least $30, but this portable version only runs you $23. While it might not provide as much power, it gains versatility and convenience. If you need a simple humidifier—especially if you travel often give this one a look.
Another HUMIDIFER, Carrying a full-size humidifier with you when you travel isn’t particularly convenient. If you still don’t want to dry out while sleeping in your hotel room, however, there is an option. South Korea’s Amazing Grace is now offering a tiny humidifier that can be placed in whatever bottle of water is close at hand.
The device is powered by the user’s laptop or by a phone charger, via a USB-to-mini-USB cable.
The humidifier consists of a main unit which rests on top of the water bottle, with a detachable 12 cm (4.7 inch)-long core which extends down into the water. Once powered up, the device draws water through that wick-like core, dispensing it into the air as vapor at a rate of 30 ml per hour. At that rate, a 500-ml bottle of water should be more than sufficient for one night – the humidifier automatically shuts off after eight hours of continuous use.
The core doubles as a filter, and should be replaced approximately once every three months – obviously, that’s going to vary greatly with the amount of use it gets. It is available for around the US$32 mark.
