Described is “Malevolence,” a hybrid electric motorcycle, including an electric motor and jet engine. The vehicle combines a traditional electric motor, powered by battery, rotating the rear wheel with torque via a chain drive, and a secondary engine utilizing an air ducting array augmented with ramjet technology, able to propel the vehicle additionally via thrust.
Kirat is an electric-powered wheelchair with facilities that can be adjusted according to the user’s needs in terms of balance, the level of comfort, and everyday life requirements. This wheelchair has the unique capacity to be adjusted with the places and paths when the wheelchair is stopped or while it is moving.
While the importance of physical (social) distancing in reducing the spread of COVID-19 has been well-documented, implementing similar controls in public transit remains an open question. For instance, in the United States, guidance for maximum seating capacity in single-destination public transit settings, such as school buses, is only dependent on the physical distance between passengers.
Think of why Tesla is a game changer in the EV space. While their vehicles are very innovative, their vast charging network is a large reason why they are so popular. Now, the most popular electric vehicles in the US/World today aren't actually electric cars, but electric bikes and other smaller forms of mobility.
Laminated Bamboo Car: Vehicles made out of a renewable material.
It can be built with a chassis made completely out of glued bamboo composites, from pre-cut kits or shared patterns, using locally-grown sustainable materials, with low-tech tools. A 15-minute You Tube video is available, including engineering, fabrication with woodworking joints, bonding and stiffness testing.
Whenever a plane touches the ground, rubber is pulverized from the tires until they adhere to the ground.
Small electric motors may be used to rotate the wheels such that their peripheral speed matches the plane speed at landing to avoid them sliding at initial touch. This avoids the tires wear and extends their number of landings.
Researchers at INL have developed a large-scale spark plasma sintering process. While small scale SPS has been accomplished, the novelty of this process lies in the tooling and knowledge developed to address the scale up issues and fabricate a viable armor tile.
The 3D printing industry has grown quickly over the last decade with average compound annual growth rates of around 27% leading to a market size of $17.7 billion in 2022. The use of 3D printing for large-scale polymer objects is also a high growth area,
Most car wheel diameters are in the range of 14 to 19 inches with such car following is submitted.
For a car with wheel diameter 14 inch (radius R= 17.8 cm) ,Circumference = 2πR, then the circumference is 111.78 cm or 1.11 meter.
For a larger wheel diameter of 28 inch (radius R=35.56 cm), circumference =2πR, the,
