Thermoelectric coolers operate by the Peltier effect. The device has two sides, and when a DC electric current flows through the device, it brings heat from one side to the other, so that one side gets cooler while the other gets hotter. The "hot" side is attached to a heat sink so that it remains at ambient temperature,
Buildings represent 30% world energy usage, of which 50% is for heating and cooling. Our technology can reduce these energy needs by up to 50%. This would have a vast impact on CO2 emissions, and wasted energy.
We are developing the smallest, lightest, strongest oil-free compressor that aims to push efficiency and reliability to new heights.
theSARCproject is developing an innovative, cutting-edge rotary compressor that aims to push compressors' power, efficiency and reliability to new heights. This rotary compressor technology features lower size, weight, cost and environmental footprint compared to conventional compressors.
COVID-19 is a disease that started in December 2019 in Wuhan, China [1]. COVID-19 is a type of pneumonia caused by a virus belonging to the coronavirus family that affects the pulmonary alveoli and generates respiratory failure [1,2]. According to reports from the World Health Organization (WHO) [3],
The digital fabrication of oxide glasses by three-dimensional (3D) printing represents a major paradigm shift in the way glasses are designed and manufactured. Automation enabled by the first industrial revolution led to the mechanization of blowing and casting processes. Despite the undeniable advantages brought by automation in terms of reproducibility, quality, and production volume,
A method of creating a permanent record of Force-time or Load-time using inexpensive pressure sensitive strips. These strips change color with applied pressure, the color being equivalent to the pressure applied.The strips are commercially available. The mechanism proposed increases the utility by giving a time resolved history of the load or force or pressure applied.
The Titus Sub Woofer is taking sub woofer design far outside the box... so to speak.
Boxed sub woofers have an inherent limitation where by the air being pushed about inside the box and through a port (if fitted) by the driver creates sound distortion and fatigue to the driver affecting it’s performance and the listening experience.
Diabetes and peripheral arterial disease are two prevalent chronic medical conditions afflicting the global population. Lower extremity disease secondary to diabetic microvascular and peripheral vascular disease often result in transmetatarsal foot amputation (TMA). Management after TMA requires extensive rehabilitation often with the aid of prosthetics. Current prosthetics lack the comfort and suspension patients required;
My proposal to eliminate the SARS-COV2 virus and end the pandemic is:
The SARS-COV2 virus has shape and mass (nanograms).
For this reason, its natural frequency (Hertz) can be calculated.
Once natural frequency is known of SARS-COV2, the same frequency can be applied externally by means of a frequency meter or láser ray,
Classically trained engineers have been left with the impression it is impossible to control 100% of the torque generated by a single lift rotor, using only the downdraft, within the same diameter as the lift rotor, because 100% of the torque minus 100% of the torque would leave no useable downdraft.
