i am still till this day amazed that a very heavy steal object can fly for thousands of miles, how about you ?\ni also think some of the best inventions are Air conditioners,refrigerators and compact discs

The airplane is one of the greatest inventions in history. The fact that today hundreds of thousands of commuters fly through the air every day is mind-boggling. The fact that most of these commuters don't know how they are managing this incredible feat and would rather watch "American Idol" than learn how is not so mind-boggling.

Yes, if you started this machine, and it kept going indefinitely, you would have a true perpetual motion machine.\n\nDo not ever let the "laws" of physics or any other science prevent you from investigating phenomenon for your own curiosity.\n\nIt wasn't that many years ago that engineers pretty much decided that a bumble bee couldn't fly. Neither they nor the bumble bee knew anything about the effects vortexes have on air pressures - and the bumble just kept flying around anyway.\n\nPresent laws of physics prohibit a perpetual motion machine - but who knows what discoveries will be made in the future - and they well could be made by someone who challenges these laws by looking at the problem from a different perspective.

Hmmm... Right now, i'm sick of traffic jam, so if I were a product dev. manager, and I can make anything I want, then I'll make a TELEPORT MACHINE: A Machine that can move you to anywhere you want in just seconds!! (You know, like those in Star-Trek or other science fiction movies..) I'm sure it'll be very, very usefull in our life, especially in BIG CITIES!!!Also, it'll lessen the air polution and much more efficient!! ^---^

Very Nobel interest. If you can build it then let me know. Here are the tips from me. Use FM band to for the controls, if you can have a digital control system then you can operate that with a high and low pulse from the ground. And if its a toy plane then there shouldn't be more then 3 or 4 controls which should be easier to design. contact me let me know the further update on your this project and any assistance.

There was an interesting special on discovery science channel a year or so ago about flight.  One topic they touched on was why the human form cannot fly.  For one, our arms do not make good air foils.  Also, our pectoral muscles are nowhere near strong enough to move our arms even fast enough if they were.  And, lastly, even if our arms were shaped properly and our pecs adequate to flap quickly enough, the human body shape isn't conducive to a good power to weight ratio in order to over come drag effect.

I've discovered that the best way to come up with an "invention" is to give yourself a number of scenarios to work with (this will narrow down the broader categories of just crime or pollution).  For example:\n\nLast week, your grandmother had her purse stolen while she was taking a walk down the street.  A man just snatched it off of her arm and ran off with it before she could react, and she had no chance of ever catching up to him.  How could purse-snatching be prevented?\n\nAlso think about which you want to choose from: how to outwit the criminal, or how to stop people from ever trying to commit the crime.  The same goes for pollution: are you going to focus on how to do something with the pollution that we've already created, or are you planning on preventing more pollution from occurring?\n\nHope these ideas will help you figure something out!  Inventing things sure can be a lot of fun when you really get into it.

Ah.. Get back with us if a few years..... lol\nThen we'll KNOW the answer.\n\nBut I would think #3.  Mount a rocket motor on it. It's got a lot of mass to get moving with the other methods not being, today, that efficient.

Going back to a capsule type system definately seems like a strange step.  \n\nBut as far as getting an effective system flying in a low budget enivronment, it is probably a good choice.\n\nI think seperating the cargo and crew flights is a good idea.\n\nI would like to see more alternative methods of getting man & material into space such as the high altitude drop then rocket burn of the Spaceship1, or the space elevator.

I parricularly like the film can cannon on http://sci-toys.com/index.html but the other sites will hopefully give you some ideas!\n\nDo a search for "weird science" or "amateur science" and you'll find lots more- just be warned: some are slightly bonkers, lethal or both!\n\nHave fun!!

I want to invent a machine that makes people young forever. \nWith my registered patent, I don't think I would have a hard time to market it.\nThe problem is I can't be young forever to invent that machine.

Probablly the most novel one that I've heard of is in the "lensman" series by EE doc smith, and it involves inertialessness. He had a device that would somehow remove the inertia of the object it was hooked to, thus making it unneccesary to accelerate. I thought this was cool; it had some really interesting ramifications. Good series, too!

That is so weird... only yesterday some friends and I were talking about an issue related to this! We were talking about how we had all heard things about inventions of efficient cars being scrapped as early as during WWII.\n\nWe hadn't heard of this movie but we will definitely see it now we know about it!

I've seen a handful of widgets - do you know what they are?  They are extinct now but they were used in factories in the UK as a measure of weight.  I was talking to a gentleman once about widgets in beer cans and he put his hand in his pocket and brought out about 30 tiny metal coin looking objects and explained the history to me.  Don't sell them for £10 they are probably worth a fortune now as collectors' items.

what the heck is a mentos rocket???  Do you put those little breath mint thingies inside a rocket and launch it?  That's weird.  Doesn't sound all that fun to me.\n\nWell, since I'm not sure what that is, I don't have any really good ideas.  \n\nBut here's some links for science fun\n\nhttp://www.funsci.com/texts/index_en.htm\n\nhttp://www.exploratorium.edu/science_explorer/

It's possible to float something on an air current.  Of course you'll need a fairly strong current to float a physical body.  Then many who study metaphysics learn how to suspend physical objects in an energy field.  I've seen this done with examples like a tissue suspending between the hands or a pencil or similar objects.  I have not seen a person suspended yet but have spoken to a few people who claim to be able to levitate.  Who knows.  I'll keep an open mind and hope to actually observe something of that nature one day soon.

Oh crap, now you opened me up to so many wonderful things! I would go sky diving, rock climbing, swimming, bungee jumping, riding motor cycles, flying planes, walk on fire (lol), swim into the deepest parts of the ocean and record things, help people, etc... :-)
