One of the holy grails of laser science far as I see it is achieving a sufficient flux to "boil the vacuum" by focusing two or more beams into as tight a point as possible. There is actually some studies being done on this now arXiv:hep-ph/0304139v1 " Boiling the Vacuum with an X-Ray Free...

Well don't know if this will help either- but if you purely are going for energy storage, have you thought about molten salts or something similar? A household thermos stores a higher energy density for longer periods of time then lith-ion batteries (not saying terribly much but never need...

Just a thought but you might be intersted in building a gasification device then add the Fischer-Tropsch process catalyzed with nickel if i recall to produce methane and water. It requires heat, and biomass, and a bit of metalwork. A rough example of a biomass chamber would be a double wall...

Consequently, OFF-Delay or programmable mode relays could let you do this with only 1 relay, and 1 float, but OFF-delay relays can be much more expensive as they incorporate a time function to the circuit. But I would highly suggest not using them for this as they cost about 5-20 times as much...

Here are some state schematics, the wiring diagram does not really show you the states, but gives you wiring information from which you can trace through and imagine any possible state. http://picasaweb.google.com/lh/photo/DT6x24WDouhg91UXPYFmeN2_0MvXy9JeVCfdQTOfeN0?feat=directlink Here you...

Here is also a diagram for the relay http://picasaweb.google.com/lh/photo/ngHmt Be sure to check the diagram printed on the relay, but they almost always are setup this way for 8 pin. 10 AMP is the typical rating on the contacts, over the course of their lifetime if the contact fails before...

http://picasaweb.google.com/lh/photo/iwTXyJWHwGLhRLD5k0vn292_0MvXy9JeVCfdQTOfeN0?feat=directlink I once again really apologize for the error I made before, but I assure you I checked this schematic... Here is the breakdown of wiring: The Hot feeding the common of the upper float once the...

1) The state of the schematic is 0 power applied. 2) Correct :) 3) OMG i goofed up my schematic- sorry I must have been rushing:bugeye: I will have another up and I will assure you it will be correct

Here is an example of a typical double pole, double throw relay that I normally use, they cost about 12-15 bucks a piece + 4-6 bucks for the base. honestly I am not sure the price of single pole double throw, but if your sump burns out the contacts on DP you can use the backup pair of contacts...

And if you have any questions do not hesitate, I pulled an all nighter and went to work today so my schematic could possibly be a little confusing looking particularly to someone who is not used to looking at them.

You can also feed this circuit using a lightswitch, providing your sump pump draws less current then the switch is rated for. So you can turn off the left relay when you know water is not going to be an issue

Meh I will explain anyway incase others do not. Ok I should have labeled the relays different, but no matter... Float one is the upper float switch, the power feeding the common will only pass the switch once the high level of water is reached. Once this happens power will goto the sump...

I can make you up a schematic using two SPST relays (single pole single throw) , you can use two DPDT but you need two coils for this, at least best i can think of at the moment hehe. If you are familiar with relays the schematic should be enough- if not I can explain to you the operation...

Hmm, are you at all familiar with relays?
