Aptera Motors
Aptera Motors (formerly Accelerated Composites) is an American startup high-efficiency car company based in Carlsbad, California. The original company, Aptera Motors, Inc., was founded in 2005 and liquidated in 2011. In 2019, Aptera Motors was re-formed by the original founders, Chris Anthony and Steve Fambro, as Aptera Motors Corp. It used a crowdfunding campaign to restart development of what is touted as the most highly efficient road vehicle in the world. The original Aptera Motors' design was a three-wheeled two-seat vehicle named the Aptera 2 Series. The marketed fuel efficiency of , when plugged in every , would have made it one of the most fuel-efficient passenger vehicles in the world. As of 2019, the Aptera had been redesigned to be a pure battery-powered electric vehicle (BEV) using under 100Wh per mile on the EPA test cycle, with a marketed EPA test-cycle range of , with solar panels that could add up to 40 miles of range per day. This makes the Aptera the most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aptera 3
The Aptera is a three-wheeled, two-passenger solar electric vehicle, the third revision of the previous Aptera 2 Series vehicle by startup Aptera Motors. It is a highly efficient battery electric vehicle (BEV) with built-in solar panels on the roof and dashboard, and optionally on the hood and hatch, featuring two or three wheel hub motors and an estimated range of up to with its biggest battery pack. Efficiency Aptera's efficiency is obtained by combining two factors: low drag aerodynamics and lightweight resin-filled sandwich-composite construction. Its calculated automobile drag coefficient was optimized via simulations to 0.13, significantly lower than any other production motorcycle or car. The 60 kWh battery version weighs only . The company says its calculations and simulations show the resulting Aptera requires less than 100 Wh of energy per mile on the EPA combined city and highway test cycle, making it about 2.5 times as energy efficient as the quite efficient Te ...

Carlsbad, California
Carlsbad is a coastal city in the North County region of San Diego County, California, United States. The city is south of downtown Los Angeles and north of downtown San Diego. As of the 2020 census, the population of the city was 114,746. Carlsbad is a popular tourist destination and home to many businesses in the golf industry. History Carlsbad's history began with the Luiseño people (the Spanish name given to them because of their proximity to Mission San Luis Rey), as well as some Kumeyaay in the La Costa area. Nearly every reliable fresh water creek had at least one native village, including one called Palamai. The site is located just south of today's Buena Vista Lagoon. The first European land exploration of Alta California, the Spanish Portolá expedition of 1769, met native villagers while camped on Buena Vista Creek. Another Luiseño villages within today's city of Carlsbad was a village at the mouth of the San Marcos Creek that the Kumeyaay called 'Ajopunq ...

TED Conference
TED Conferences, LLC (Technology, Entertainment, Design) is an American-Canadian non-profit media organization that posts international talks online for free distribution under the slogan "ideas worth spreading". TED was founded by Richard Saul Wurman and Harry Marks in February 1984 as a tech conference, in which gave a demo of the compact disc that was invented in October 1982. It has been held annually since 1990. TED covers almost all topics – from science to business to global issues – in more than 100 languages. To date, more than 13,000 TEDx events have been held in at least 150 countries. TED's early emphasis was on technology and design, consistent with its Silicon Valley origins. It has since broadened its perspective to include talks on many scientific, cultural, political, humanitarian, and academic topics. It has been curated by Chris Anderson, a British-American businessman, through the non-profit TED Foundation since July 2019 (originally by the non ...

Ultracapacitors
A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than other capacitors but with lower voltage limits. It bridges the gap between electrolytic capacitors and Rechargeable battery, rechargeable batteries. It typically stores 10 to 100 times more specific energy, energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more charge and discharge cycles than Rechargeable battery, rechargeable batteries. Supercapacitors are used in applications requiring many rapid charge/discharge cycles, rather than long-term compact energy storage — in automobiles, buses, trains, cranes and elevators, where they are used for Regenerative brake, regenerative braking, short-term energy storage, or burst-mode power delivery. Smaller units are used as power backup for static random-access memory (SRAM). Unlike ordinary capacitors, supercapacito ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continuously Variable Transmission
A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds. CVTs are used in cars, tractors, side-by-sides, motor scooters, snowmobiles, bicycles, and earthmoving equipment. The most common type of CVT uses two pulleys connected by a belt or chain; however, several other designs have also been used at times. Types Pulley-based The most common type of CVT uses a V-belt which runs between two variable-diameter pulleys. The pulleys consist of two cone-shaped halves that move together and apart. The V-belt runs between these two-halves, so the effective diameter of the pulley is dependent on the distance between the two-halves of the pulley. The V-shape ...

DC Motor
A DC motor is any of a class of rotary electrical motors that converts direct current (DC) electrical energy into mechanical energy. The most common types rely on the forces produced by induced magnetic fields due to flowing current in the coil. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor. DC motors were the first form of motors widely used, as they could be powered from existing direct-current lighting power distribution systems. A DC motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and appliances. The universal motor, a lightweight brushed motor used for portable power tools and appliances can operate on direct current and alternating current. Larger DC motors are currently used in propulsion of electric vehicle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Three-wheeled Car
A three-wheeler is a vehicle with three wheels. Some are motorized tricycles, which may be legally classed as motorcycles, while others are tricycles without a motor, some of which are human-powered vehicles and animal-powered vehicles. Overview Many three-wheelers which exist in the form of motorcycle-based machines are often called trikes and often have the front single wheel and mechanics similar to that of a motorcycle and the rear axle similar to that of a car. Often such vehicles are owner-constructed using a portion of a rear-engine, rear-drive Volkswagen Beetle in combination with a motorcycle front end. Other trikes include that are specially constructed for off-road use. Three-wheelers can have either one wheel at the back and two at the front (2F1R), (for example: Morgan Motor Company) or one wheel at the front and two at the back (1F2R) (such as the Reliant Robin). Due to better safety when braking, an increasingly popular form is the front-steering "tadpole" or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subcompact
Subcompact car is a North American classification for cars smaller than a compact car. It is broadly equivalent to the B-segment (Europe), supermini (Great Britain) or A0-class (China) classifications. According to the U.S. Environmental Protection Agency (EPA) car size class definition, the subcompact category sits between the "minicompact" and "compact" categories. The EPA definition of a subcompact is a passenger car with a combined interior and cargo volume of between . Current examples of subcompact cars are the Nissan Versa and Hyundai Accent. The smaller cars in the A-segment/city car category (such as the Chevrolet Spark and Smart Fortwo) are sometimes called subcompacts in the U.S., because the EPA's name for this smaller category — "minicompact" — is not commonly used by the general public. The prevalence of small cars in the United States increased in the 1960s due to increased imports of cars from Europe and Japan. Widespread use of the term subcompact coincide ...
