HK Case: Samsung Energy Management added by Raphaelle

The video is entertaining to watch and also quite informative about saving energy by using solar panel. In the video, they change electricity from external power to solar energy to turn on devices and it really helps reducing energy consumption in households. However, the concept is not really implemented by many people since the cost to make every house devices 'smart' or connected by a single remote is very expensive. Also, a huge amount of solar panels are needed to power devices in the video. In the near future, this might be the solution to save energy. 90/100

Smart Energy Management for Any Size Building added by Raphaelle

The video illustrates that every building can be installed a system called SmartStruxure, the system can optimize energy usage in broad daylight and the owner can turn off energy usage at night via wireless connection. I think the idea of a building that can be controlled wirelessly is great, nevertheless the system itself is powered 24/7 by energy. 80/100

Saltwater Lamp added by Mi Hongyu

By using an electrochemical cell, salt water/sea water can generate electrical energy from chemical reactions. The invention is useful in country like Hong Kong where access to sea is easy. However, the durability and the usage time is not high, so I think that is why this product rarely used by people. 80/100

Priva ECO added by Kwok Shi Ming Jasmine

The website shows that Priva ECO is an Artificial Intelligence that can learn how to automatically optimize energy usage and climate condition in buildings. Priva ECO can be great solution to our future to manage household energy usage since AI can learn continously to save energy. 90/100
