No. There’s log data kept for maintenance purposes, but Tesla doesn’t keep “driving history” if you mean location history because it would go against the privacy policy. Certain amounts of the historical data may be kept by Tesla but not … Continue reading →

While a car battery can’t pump a dangerous amount of amperage into your body, a metal wrench has far less resistance, and will tend to grow extremely hot, and may even become welded in place, if it bridges battery positive … Continue reading →

Built by Herrenknecht, a world leader in TBM manufacturing, at its factory in south-west … Continue reading →

Unlike many self-driving car companies, Tesla does not use lidar, a more expensive kind of sensor that can see the world in 3D. It relies instead on interpreting scenes by using the neural network algorithm to parse input from its … Continue reading →

Autopilot. Built on a deep neural network, Autopilot uses cameras and ultrasonic sensors to see and sense the environment around the car. This robust sensor and camera suite provides drivers with an awareness of their surroundings that a driver alone … Continue reading →

Horizon Robotics－a Chinese AI chip startup－is stepping up efforts to develop smart chips for autonomous driving. “The auto industry has fully entered the intelligent stage. What company makes the chip for self-driving cars? Nov 16 (Reuters) – Qualcomm Inc (QCOM. … Continue reading →

An AI-enabled milestone The MPC3 marks a major stride toward autonomous vehicles, an advance impelled mainly by artificial intelligence. To develop the camera, the Bosch team took a multi-path approach. Who makes cameras for driverless cars? Velodyne Lidar, the leading … Continue reading →

A 36 volt golf cart is adequate for 2 to 4 passenger use when you are primarily using it on flat a flat surface. The average drive time or range for a 36 volt DC system is about 30 miles … Continue reading →

Since 1992, coins have been made with steel, which is magnetic. (Pre-1992 coins are made out of bronze, which will not attract.) Do magnets stick to coins? Many coins contain nickel and are most definitely magnetic, the magnet will ‘stick’ … Continue reading →

Their graphene sample is diamagnetic like graphite and exhibits only a weak paramagnetic contribution noticeable below 50 K. In the above reported works [20], [21], [22], graphene samples show different kinds of magnetic behaviours such as paramagnetism, ferromagnetism and antiferromagnetism. … Continue reading →

A typical 4 cylinder engine with a reduction gear starter … 250 amp surge tapering off to 60 to 100 amps cranking. How many amps does a car use at idle? Typical Current Loads for Automotive Systems, Lighting and Accessories: … Continue reading →

A graphene-based sensor for detecting gas molecules works by measuring alterations in the electrical conductivity of the material. Graphene-based gas sensors operate by adsorbing a gas molecule on the graphene’s surface, which acts as donors or acceptors of electrons. What … Continue reading →

Even though most car batteries are only 6 or 12 volts, a 12-volt battery can produce as much as 600 amps. Amperage can be thought of as the volume of electricity that’s generated, but voltage can be thought of as … Continue reading →

On average, a gasoline-powered portable generator will run for 7.5 to 12 hours, though some models can run for close to 24 hours. This may be plenty of time if you are running a generator at a campsite or worksite. … Continue reading →

Starters and generators weigh about 20 to 25 pounds, and alternators weigh about 12 to 15 pounds. Starters, generators, and alternators contain an average of 2.8, 2.6, and 1.5 pounds of copper, respectively. How much is a alternator worth in … Continue reading →
