The Tesla turbine uses the boundary-layer effect, instead of the method employed by more conventional turbines, wherein a fluid acts on blades. The Tesla turbine is also referred to as the bladeless turbine, boundary-layer turbine, cohesion-type turbine, and Prandtl-layer turbine. The latter is named for Ludwig Prandtl.
Hobbyists often build their own EVs by converting existing production cars to run solely on electricity. There is a cottage industry supporting the conversion and construction of BEVs by hobbyists. [13] Universities such as the University of California, Irvine even build their own custom electric or hybrid-electric cars from scratch.
Every human activity, transport and industrial process generates waste heat, being possible to harvest residual energy from cars, aircraft, ships, industries and the human body. [1] From cars the main source of energy is the exhaust gas. [32] Harvesting that heat energy using a thermoelectric generator can increase the fuel efficiency of the car.
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
This type is actually electric vehicle that is powered by electric energy generated using onboard fuel cell. Fuel cell uses hydrogen stored in hydrogen tanks and oxygen from the air to create water and electricity. Water is discarded but electricity is used for propulsion. Similarly to Hybrid Electric Vehicle, there is a small traction battery.
A year later, in 2010, Cavallaro successfully tested the vehicle, achieving more than twice the speed of wind, [2] definitively demonstrating that it is possible to build a vehicle which can achieve the claim. [11] [4] A second test with an improved vehicle in 2011 reached close to three times the speed of wind. [5]
Vortex generators are most often used to delay flow separation.To accomplish this they are often placed on the external surfaces of vehicles [4] and wind turbine blades. On both aircraft and wind turbine blades they are usually installed quite close to the leading edge of the aerofoil in order to maintain steady airflow over the control surfaces at the trailing edge.

A computer system that controls a device or system, with no or a minimal user interface; for example, the ignition system in a car may have a microprocessor to control it. enameled wire Wire insulated with a thin flexible layer of enamel, used for electrical windings. energy demand management A system to adjust energy demand to reduce costs.
