二人用練習機として設計された、ピピストレル社のアルファ・エレクトロは全電動を思わせる航空機だ。訓練用として短距離での離陸ができるので、小さな離着陸場での利用ができ、秒速5mで素早く上昇する。また1回あたりの充電で1時間の飛行が可能だ。ピピストレル社によると、全電動パワートレインで最大70%パイロットの訓練コストを削減でき、操作もレバー1本というシンプルさを実現しているため、今後はパイロットがより技術的なスキル習得により集中することができるとされている。全電動としては初となるアメリカ連邦航空局認証を取得し、我々の身近に登場するのも時間の問題だろう。
Running 26.2 miles is a lot different than tackling your local charity 5K. To accommodate the needs of marathon runners, Nike created the Alphafly line, now in its third generation. It employs two types of Zoom cushioning — a high-stack ZoomX foam midsole that encourages a smooth transition and Air Zoom units in the forefoot for an energy return boost. A wide, full-length carbon fiber Flyplate improves forward propulsion, and the breathable Atomknit 3.0 upper is paired with a lacing system designed with racer input to enhance comfort.

With the S8 MaxV Ultra, Roborock ensures every inch of your house is clean. The new model features a Flexi Arm Design with an extendable side brush that reaches into corners, while an Extra Edge Mopping System cleans along edges. A Reactive AI 2.0 Obstacle Recognition uses a 3D structured light and an RGB camera to identify and avoid obstacles in its path, and a PreciSense LiDAR navigation system scans rooms to create a map and determine the most efficient route. It upgrades suction power to 10,000Pa to pick up even more dust and dirt, a Carpet+ Boost System ups the hair pick-up rate by 30%, and the mopping system scrubs floors 4,000 times per second, detecting carpets and rugs along the way. With built-in voice assistance, users can start cleaning with a simple command, and when the job is done, the vacuum will retreat to its dock to automatically empty, wash, dry, and recharge itself. The S8 MaxV Ultra will be available April 22, 2024, and for a limited time, get a triple gift pack valued at $1,000 with your purchase.
