AI Thread Summary
Triangular toothpick ion engines, or lifters, are intriguing devices capable of rising from the ground, unlike traditional ion engines used in space. Their operation relies on the thrust-to-weight ratio, where insufficient thrust results in no acceleration. These engines utilize ions, often from air, making them ineffective in the vacuum of space where particle density is extremely low. Additionally, if lifters draw power from external wires, they do not lift their power supply, which impacts their overall weight. Ion thrusters are effective in low-gravity environments due to their high specific impulse but produce low thrust.

These are machines that I just learned about while I was bored. So, i will now ask about what looks like a triangular toothpick ion engine.

So these lifters are really strange, I don't know how they work,

here they are.

From what I have read though, they are ion-like engines, which are capable of on-ground rising, something ion-engines in space can't do.

Well, one has to look at thrust to weight ratio. If thrust is less than weight, there is not acceleration. Also, consider what ions are being used. If the ion lifters use air, then they would be useless in space, which is essentially a vacuum, i.e. very low particle density. And lifter capability would diminish with altitude.

If lifters receive power from wires, then they are not 'lifting' the power supply, which would add weight.

See this article for more information -

Ion thrusters do work in space - in 'low' gravity fields. They have relatively high Isp (specific impulse), but low thrust.

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
