Mengubah sepeda kayuh menjadi sepeda elektrik

Shimano, perusahaan di Eropa, sedang mengembangkan berbagai piranti untuk mengubah sepeda kayuh tradisional menjadi sepeda bertenaga listrik. Shimano membuat beberapa piranti untuk memberikan daya listrik tambahan bagi sepeda kayuh. Misalnya, satu motor listrik berdaya 250W dapat membuat sepeda berjalan dengan kecepatan 25 km per jam, sementara piranti pengereman akan membuat baterai lithium-ion 24V/4.0Ah terisi ulang.

Penghemat daya listrik pada lampu

Cavet Technologies mengembangkan piranti penghemat daya listrik yang bisa menghemat daya sebesar 30%-40%.
Piranti tersebut bekerja dengan memutus-sambung daya listrik pada lampu selama beberapa nanodetik, yang karena cepatnya tidak akan terindera oleh manusia. Cara itu seperti algoritma kompresi MP3, yang mana bit tertentu dihilangkan untuk mengurangi ukuran file tetapi tidak merusak kualitas suara yang dikompresi secara berlebihan.

Tonji University Shanghai’s Bambu House at the European Solar Decathlon is a beautiful sun-powered abode inspired by nature. It has two elegant sloping roofs and is almost entirely constructed from bamboo. Its impressive solar array generates 9 kilowatts of electricity which powers its one bedroom, one living room layout. We love how the house combines traditional Chinese architecture with state of the art technology — it has temperature and humidity control systems, high-level thermal insulation systems, and a bamboo enclosed garden.

Tonji University’s team has 20 members and is composed of doctors, postgraduates, and undergraduate students who range across many disciplines — from architecture and urban planning to energy development. They hope that their solar-powered house can help promote their forward-thinking ideas about renewable energy use in residential urban areas. The team has spent six months designing and constructing the house from scratch and they are hoping their hard work will pay off. Structurally, the house is strongly influenced by traditional Chinese architecture but with a tinge of the efficient look of contemporary architecture.

The Solar Decathlon Europe kicked off with a bang today and Inhabitat is on the scene to provide a first peek at the amazing sun-powered architecture on display. The European Solar Decathlon is the sister of the US Solar Decthalon — which we covered in Washington DC this past October — and was organized in a partnership between Government of Spain’s Ministry of Housing and the United States Government. The decathlon is taking place all through next week in Madrid, so stay tuned to Inhabitat as we bring you a front seat view of all the action!
