My thought was a thrill ride for those crazy people who base jump and such. Recently saw a show where a guy used one of those sailing suits to land in a pile of boxes without a parachute. Last guy who tried that mixed the boxes and died. This could another one of those first. First to...

First, this is just something I've wondered for fun...not serious, and just wonder if if the laws of physics make this possible. Would it be possible to create a drop pod shape such that a person could be dropped from a helicopter from a high altitude and have it hit the water (ocean) such...

Damn right I do! Considering everything in that picture will now fit into a box smaller than the average carry on suit case. That's my entire point. We broke them into small discrete devices because we had to. We don't have to anymore. And I'm not saying do away with the devices. I'm...

"Oh I get the idea... " Clearly you're messing with me now. It's for online banking, Microsoft Money, password protected stuff...things I do actually care about someone getting access to.

"Maybe you're too young to remember the nightmare that was central processing units and dumb terminals." Actually, I was a Citrix thin client administrator. That's where this idea comes from. I managed a system solo, part time as my primary function was network administrator, for over 300...

No, I'm just saying why not at least a start to interoperability, added functionality and the ability to segregate functionality by user/purpose? We always hear about smart technology but everyone is building their smart technology to be stand alone with limited interoperability. 40 years ago...

Smart? I would argue that point. I've got a blackberry that can't only 'talk' one application with my computer (email) unless I really want to view that .pdf on a 3" screen scrolling like mad. A Kindle, once again one app and that's just to load the Kindle with a book. GPS, one function and...

With the advances in computers you can now get a server with phenomenal computing power and most homes have multiple computers in them. I'm interested in the concept of a single computer with 'access portals'. The access portals would be nothing more than a monitor and keyboard with the...

I don't see any discussion here regarding the increased mass of a rotating body. Doesn't E=MC squared mean that any object in motion gains mass due to the kinetic energy. And if mass increases so does gravitational pull between the objects (earth and myself). Also, if the Earth stopped...

I figured I'd end up here :smile: A whole bunch of questions I don't have the answer to. This is basically a design much like those you see on the internet that you hold on your hand and they run off the heat of your hand. Upper temp would be sunlight on a black piece of painted aluminum...

I understand and appreciate the response. I built the container. It is for a low temperature Stirling engine. I'm not looking at putting too much pressure into it but considering PSI means every square inch I'm aware that a low pressure could be quite a bit of pressure on the plates. I...

How much pressure can I safely put in the following container. Two round flat aluminum discs with an acrylic cylinder. The discs are 6061 1/8" thick aluminum. The cylinder is acrylic .25" thick, 1 inch high, 6" OD. The discs are just larger than the cylinder and have 18 holes just outside...

Hmm...not sure I follow. What I'm trying to do; I have four pistons with magnets in them oscillating back and forth, each 90 degrees out of phase of the previous. The pistons have different pressures on them at different times during the stroke. Can I use multiple coils around the pistons...

I've already done an experiment to show that if I take two coils and connect the leads together I can physically move one magnet towards the first coil and it will draw a second magnet towards the second coil. Of course this depends on how you wire the coils together as it can also repel the...

I dabble in miniature milling/machining with my home CNC setup. I'm building a low temperature engine and have a question. The piston will be a neodymium magnet(s) set in graphite. Rather than using mechanical linkages and a crankshaft I want to use magnets to control the length of throw. By...
