To dampen these fluctuations and extend the battery's lifespan, researchers have designed an all-season thermal cloak that can cool an electric vehicle by 8°C on a hot day and warm it by 6.8°C at night. The cloak, made predominantly of silica and aluminum, can do so passively without outside energy input and operates without any modification between hot or cold weather.

The roughly 1.5-foot-long semi-sub prototype, built with off-the-shelf and 3D-printed parts, showed its seaworthiness in water tests, moving quickly with low drag and a low profile. This vessel-type isn't new. Authorities have discovered crudely made semi-subs being used for illicit purposes in recent years, but the project aims to demonstrate how engineer-developed half-submerged vessels can efficiently serve military, commercial and research purposes.

And that strengthened sense of being a timely user of new gadgetry was linked to a higher likelihood that the test-driver would show interest in buying the car, the study suggested.

The innovation could significantly expand the scope of robot-assisted tasks. Mon, 19 Dec 2022 12:43:28 EST //www.koonmotors.com/releases/2022/12/221219124328.htm
