Energy Storage
The storing of electricity typically occurs in chemical (e.g., lead acid batteries or lithium-ion batteries, to name just two of the best known) or mechanical means (e.g., pumped hydro storage). Thermal energy storage systems can be as simple as hot-water tanks, but more advanced technologies can store energy more densely (e.g., molten salts ...
Energy cost and efficiency of riding aerodynamic bicycles
The energy cost of cycling per unit distance (Cc, J.m-1) was also measured for AT and TT bicycles from the ratio of the O2 consumption above resting to speed, in the speed range from 4.7 to 11.1 m.s-1. The Cc also increased linearly with v2a, as described by: Cc = 30.8 + 0.558 v2a and Cc = 29.6 + 0.606 v2a for AT and TT bicycles.

Why Does a Bicycle Stay Upright? Exploring the Physics of Balance
When a bicycle leans to one side, the front wheel automatically turns in the same direction, causing the bike to correct its balance and stay upright. This happens because of the way the front fork is designed. The front fork of a bicycle consists of two main components – the steerer tube and the fork blades.
