Q & A
What is the main purpose of the laser system that Drake bought?
-Drake bought a sketchy laser welding and cleaning system primarily for the excitement of experimenting with its high power output, despite not having enough practical tasks to justify its purchase.
What is the power output of the laser system?
-The laser system has an output power of 2,000 Watts, making it the strongest continuous wave (CW) laser Drake has shown in his videos.
How does Drake demonstrate the laser's cleaning capability?
-Drake demonstrates the laser's cleaning capability by using it to remove rust from a rusty air cleaner and a rusty barrel, showing the effectiveness of the laser in stripping off the rust and leaving a shiny surface.
What is laser ablation, and how does it work?
-Laser ablation is a process where a material's surface is removed due to explosive boiling caused by high power density. The intense laser beam is focused on a small area, causing the material to rapidly heat and essentially explode off the surface.
What happens when the laser is used on red iron oxide?
-When the laser is used on red iron oxide, it is reduced to black iron oxide, which is more ferromagnetic. This reaction occurs at very high temperatures, indicating the laser's ability to heat substances to extreme temperatures.
How does Drake attempt to increase the laser's effective range for burning objects?
-Drake attempts to increase the laser's effective range by constructing a telescope using a 400-year-old invention. The telescope is designed to widen the laser beam, reducing its spread and increasing its burning ability over a longer distance.
What type of objects does Drake successfully burn or clean with the laser at a distance of 70 meters?
-At a distance of 70 meters, Drake successfully burns through drywall, a steel plate, and a fire brick, and also ignites thermite and firecrackers. He also manages to open a can of soda and pop an aerosol can.
What is the maximum burning range Drake calculates theoretically for the laser setup?
-Theoretically, using the Stefan-Boltzman law and approximations, Drake calculates a maximum burning range of 4 kilometers (2 and a half miles) for the laser setup.
How does Drake ensure safety and prevent fires during his experiments?
-Drake ensures safety by conducting his experiments in a controlled environment where he can confidently know that the laser beam will stop and not leave his property. He also mentions that the risk of lighting the forest on fire is zero due to the recent rain and his expertise in burning things in the woods.
What่ตๅฉๅ provided Drake with the equipment to help stabilize his laser experiments?
-Flexispot provided Drake with a C7 chair and E7 plus desk combo, which contributed to the stability needed for his long-distance laser shots.
What was the outcome of Drake's attempt to ignite a propane tank with the laser?
-Drake was able to briefly ignite the propane tank by keeping the laser focused on the leaking gas, but it did not cause a significant explosion or fire.
