Renewable energy based automatic recharging mechanism for full electric vehicle
TL;DR: In this paper, an automated charging mechanism (ACM) automatically recharged the battery packs, therefore, no need to wait for recharging EVs thereby increasing the traveling distance, and the authors strongly believe that the method proposed decreases the complete travel time and as well as in increased EVs usage.

Comparison of direct-drive and geared generator concepts for wind turbines
TL;DR: The DFIG1G seems the most attractive in terms of energy yield divided by cost, but the DDPMG has the highest energy yield, but although it is cheaper than the DDSG, it is more expensive than the generator systems with gearbox.
