Abstract: A microfluidic detection unit comprises at least one fluid injection section, a fluid storage section and a detection section. Each fluid injection section defines a fluid outlet; the fluid storage section is in gas communication with the atmosphere and defines a fluid inlet; the detection section defines a first end in communication with the fluid outlet and a second end in communication with the fluid inlet. A height difference is defined between the fluid outlet and the fluid inlet along the direction of gravity. When a first fluid is injected from the at least one fluid injection section, the first fluid is driven by gravity to pass through the detection section and accumulate to form a droplet at the fluid inlet, such that a state of fluid pressure equilibrium of the first fluid is established.

Abstract: This invention relates to an installation for harvesting renewable energy. The installation includes a first part, a second part and a harvesting means. The first part includes a first harvest point, a weight element and a first connecting element while the second part includes a second harvest point and a second connecting element. The harvesting means is connectable between the first harvest point and the second harvest point. The first connecting element and the second connecting element are freely connectable to each other to allow the first part and the second part to move relative to each other in response to renewable energy impacted on the installation, translating kinetic energy to the harvesting means.
