I do not think it was outside the OP question,
The link I provided shows acuall data with thrust of 55 lbs with 27" prop at 7,000 RPM, which is relevant to the question above, as it shows feasibility.
BTW I'm not suggesting he buy a turboprop, or turbine engine.
No need to curse.
Example I linked, just demonstrates that many pounds (>40lb) of thrust can be generated with an smaller prop 27" and under 10k rpm with the proper torque, as that was my only point.
btw the permits you talk about are at --> http://www.modelaircraft.org/documents.aspx...
All depends on torque, rpm, and prop type,
on http://www.jetcatusa.com/spt5.html it's specs are
Thrust: 55 lbs with 27" prop at 7,000 RPM
Though this is using 27" prop, also I would research more on this subject.
If you ask questions in a logical a manner, and check your grammar (so that...
This is correct, original poster could be facing "criminal negligence" if used in a improper manner, basically anywhere outside, or in a room with people.
Yes you can, see my previous post.
BTW please if you do an laser project, please Google "SAM FAQ laser guide" and read all the safety parts. And at Minimum buy (ebay) laser eye protection wear that matches your laser diode range.
How efficient is bad to you?
Modern laser diodes (multi watt) are have greater efficiencies than 50%.

In fact, high power laser diodes - those outputting WATTs of optical power - are without a doubt the most efficient light emitter - not...
Something that always got me thinking about is time is relative to the speed of the object (time dilation) how can we determine age of universe.
Here is an example of what I'm thinking.
When the big bang happened, imagine if certain parts of the big bang it got flung at different speeds...
I recommend asking people who talk about Tesla Coils all the time, and have good experience at it.

Cool to see another CNC person here, I've did my own X2 CNC Mill conversion recently.
The "008" of "SV008IC5-1F" says it's 0.75 kw time to upgrade to get those faster IPM speeds.
btw have you tried CNCzone.com before, people there are good at answering CNC stuffs like this.
If your looking to making power, grab an peltier.
For example take a look at http://www.make-digital.com/make/vol15/?pg=125

lol a little long winded, but I get it!
Just confirming, the springs are attached to the slower conveyor belt, and attached automatically to the package as they are dropped, when they slingshot forward at 2x speed the spring detaches, and package lands on 2x speed conveyor belt. Since the...
