They were able to get 50% more energy out of the fusion experiment at LLNL. However, to do that required MANY GIANT LASERS. How else can you get a fusion reaction going without so many giant powerful lasers to get it started? It seems so impractical to have fusion energy for the masses.

Water inside an ultrasonic cleaner (operating in the 40,000kHz range) rill ripple so very slightly, but what Hz is created with standing water (in a container) sat above a washing machine on full spin (1200rpm) ?

Hello everybody, I have created a proposed StackExchange for SolidWorks Electrical users. I'm curious if anybody on the forum is interested in the topic and if so what has been your experience with the software? Any tips and tricks you may have would be appreciated. I'm not sure if I can link the site here, but if your interested its located on StackExchange Area51 under "SolidWorks Electrical". There's so little resources for this software online, any input and support would be beneficial for the community.

I've been messing around with a diaphragm I've gutted from an old keurig machine. I'm trying to learn more about gas compression methods, and the transportation of gasses. I believe the pump was intended more for water than air (gasses), which might be much of why I am having a hard time achieving higher psi through this pump. In what I've gathered so far: the weak point seems to be the actual diaphragm itself. The check valves should operate the same no matter what pressure is applied because of the counteracting forces. I believe I foolishly tried to increase the area of expansion and contraction of the diaphragm by replacing it with a balloon. It appears …

Could the Earths Em field be used to propulse a craft into space ? In engineering terms , could we create a device that could manipulate the Earths Em field to create some sort of spatial wormhole ? If we could create a device that curved the field in a -ve manner towards the device , wouldn't space be closer ?

Would a helium filled rocket ''top section'' help the rocket to vertically land ?

Would a rocket be more structually stable with a vacuum layer between the inner body and external body ?

Hey, everyone Would it be possible to take advantage of the fact that the engine in the car heats up which could be used to "boil" the water to produce steam, which could be used to extract energy capable of powering the car? This question has been bothering me for a long time and I decided to finally ask someone about it. I say right away that I don't even know if this all makes any sense (it was just a loose thought in physics class) so I sincerely ask you to explain in a relatively simple way why this can't be the case or what the obstacles are. thank you for giving me your time.

Hi team, I was wondering how to determine whether a helicopter is good. As an example, with an Army tank, you would judge it on the criteria of protection, firepower, sensors, and mobility. Are there specific things that you can look at to determine that a particular type of helicopter is going to be "better" than others? I am mostly thinking in a military context. I am particularly interested in comparisons between a Blackhawk/NH-90/Mi8 helicopter.

ABOARD THE PLAT-I 6.40 GENERATING PLATFORM, Nova Scotia — The Bay of Fundy, off the Canadian provinces of Nova Scotia and New Brunswick, has long tantalized and frustrated engineers hoping to harness its record-setting 50-foot high tide to generate electricity. After more than a century of attempts, there has only been one small power-generating station, since closed, and countless broken dreams, abandoned plans and bankruptcies. Even so, a new coalition of entrepreneurs and scientists in Nova Scotia are trying again. One participant, a company called Sustainable Marine, has devised a new technology and successfully operated it for more than seven mo…

Greetings. Am curious about a formula 1 racing engine. How is the engine coolant thermostat ? No guesses, please.

Hello What fields/areas do you think you should study to at least have hope to be able to try to achieve creating an artificial brain and doing mind uploading ? Here are some Wikipedia articles that I think could help doing this : https://en.wikipedia.org/wiki/Artificial_neural_network https://en.wikipedia.org/wiki/Biotechnology https://en.wikipedia.org/wiki/Nanotechnology https://en.wikipedia.org/wiki/Technological_singularity https://en.wikipedia.org/wiki/Brain–computer_interface https://en.wikipedia.org/wiki/Electroencephalography https://en.wikipedia.org/wiki/Brain https://en.wikipedia.org/wiki/Magnetoencepha…

Hi there! I have few years still without any solution. I could find just only one exemplary of this bulb or lamp there I share pictures, this is exactly what I need to know what it is, brand or datasheet. The base is E27. AND the most important, In this VIDEO you can see the lamp working: (I don't know is this usage is the correct usage, the lamp is powered with HV with only a single cable, it runs like a Plasma ball lamp) - Aparenlty these lamps are used to generate ozone. Hope you can help me! I have YEARS with this issue... I never could resolve it... Kindly Regards ;D

I just found out that Silicon is a kind of metal, which apparently has nothing to do with the periodic table, and everything to do with it not ending in a vowel. I was wondering, does Silicon have useful properties for use in kitchen interior ?

If a 200mAh 3.7V battery (0.74Wh) takes 1.5hrs to charge over USB-C, is there any benefit to charging to one the of available higher standards above 3A (USB-C v1.2) i.e. USB PD v3.0 will charge at 20V/100W/5A. Many thanks.

I am looking for right-angled metal cubes, with one vacant face to allow for concentric nesting, their tight tolerances allowing them to slowly sink under the force of gravity. Although CNC milled options would achieve this, are there any cheaper manufacturing methods ?

With the search for oil and gas in the North Sea, significant coal deposits were discovered in this sea (1). The localization of these deposits in a sea-bed prohibits a traditional exploitation by mine. In situ combustion was considered with an aim of generating a combustible gas mixture easier to extract. But this technique was too polluting. There is perhaps another resource to consider: the methane adsorbed in the pores of coal. This type of gas is called CBM for Coal Bed Methane (2). Several data could promise a significant and exploitable gas resource: - the amount of coal present under the North Sea seems significant; the amount …

While my hunky husband was lifting the chair up, and my brawny brother pushing the frame down, I kept hitting the top of the slide with a screwdriver, to try to loosen the slide. But these parts are still wedged too tightly! We ran out of energy and ideas! How can we life hack this please? https://imgur.com/Hu6rV57 GIF from this video. Illustration from this PDF. Chair manufacturer's page list these both.

A Swiss company is exploring the measurement of perceived time (v.s. universal time) and is developing a device to measure personal time based on biometrics. Exciting perspectives. Their video presentation can be found here:

Hi. Any methods for milling channels in silicone rubber that you may suggest ?

Given that there is a general understanding that large surface vessels, like shipping containers, are likely to benefit from being converted to being Hydrogen powered, over other non-polluting technologies like batteries, what are the practicalities of this ? On average a shipping container, worth its salt, will look something like this: Length : 400m Beam : 60m Draught : 14m Gross Tonnage : 210~235 TEU : 20~24k The fuel that powers their diesel engines is either IFO180 / IFO380, of which is trading today (mid-2022) at $506/mt on the World Bunker Prices index (Rotterdam) I read online that a 10k TEU container ship running at …

Here is the idea. If an air conditioner was powerful enough, with intake and exhaust designed properly, you can remove Coronavirus (or any virus) from the air by the A/C moving the air faster than normal in an upward direction. You want the air to circulate so fast that if someone sneezes the water droplets will remain inside the room only a few seconds before it is sucked out the ceiling vent. For cooling the room, the idea is cool air enters the room near the floor and the warmer air exits through a ceiling vent, the "return." For heating the room you would also introduce warm air through low floor-vents, then the exhaust exits through the return in the ceilin…
