How much energy can be extracted from collecting electrons from enriched uranium? In other words, using the uranium as a power source without detonating it.

depends on what Uranium Isotope you are referring to. Uranium are mainly Alpha emitters but there are beta emitters like 237 U. the half life is what you are looking for.
Which?
218 U
219 U
220 U
221 U
222 U
223 U
224 U
225 U
226 U
227 U
228 U
229 U
230 U
231 U
232 U
233 U
234 U
235 U
236 U
237 U
238 U
239 U
240 U
241 U
242 U
with most Uranium Isotopes you might want to look into Thermal piles that convert heat into electricity, it is still dependent on the amount of Neutron flux in the near critical mass of Uranium, even near critical Uranium will melt and start spalling all over the place. one pound of pure Uranium would only feel warm in your hand all the time.
Uranium-235 has a half-life of 700 million years and was discovered in 1935 by Arthur Jeffrey Dempster. Its nuclear cross section for slow thermal neutrons is about 1000 barns. For fast neutrons it is on the order of 1 barn. Most but not all neutron absorptions result in fission; a minority result in neutron capture forming uranium-236. The fission of one atom of U-235 generates 202.5 MeV = 3.244 × 10âˆ'11 J, i.e. 19.54 TJ/mol= 83.14 TJ/kg
Critical Mass happens at; For pure U-235, that is 52 kg; for Pu-239, it is 10 kg.
Plutonium makes a very efficient thermal pile because it requires a great deal less in mass to do the same job as Uranium. Governments would never allow civilians Pu for even the slightest moment to research free energy. one little pinch of it would put anyone in jail for life. or darn near it.
All that I know is that batteries like this already exist, but I do not know the details. I'm curious about electrical output.
The Pu is an extremely poisonous over toxic than radiation.

The Cassini spacecraft is powered by 2 nuclear batteries which give about 500 W each.

Any idea on the dimensions and weight of the two batteries. 500 W is a powerful output! Also, any idea on the expected lifespan?

But yet all Cassini developers survived building it, it has to do with safety factors, if you don't have safety factors then it is hazardous other wise it is totally safe. this is a fact.
the number one rule: Safety first!
Isotope studies are my favorite subjects in Chemistry. I love Nuclear Chemistry.

I just found info that the Cassini battery can produce 700 watts for at least 11 years.
I didn't find out the weight to power ratio or even the dimensions of the RTG (radioisotope thermoelectric generator) battery. However, NASA's documentation did state that the plutonium was a small amount... whatever that means.
Cassini had 3 RTG's with a total of 32.9kg of Plutonium.
Or something like this?:
Most thermonuclear junction batteries and their derivatives are step down joule thief circuits..often they have an electromagnetic reed switch instead of a transistor ..they collect voltage, and at a defined rate, the switch clicks on and pulses through a coil - using a small transformer they charge a capacitor and discharge as a normal battery would.
In other words, they would behave as a lead acid, in that they would have a cranking amp rating, then a continuous discharge rating. One would not be able to differentiate the source electricity from a car battery.
A good example of utilizing the eV's derived from a nuclear source would be to supply a high voltage low current device. ..this is impractical so long as we're mainly using the reciprocal, higher current lower voltage. Therefor this conversion takes place.
It would be advisable to fisrt develope a high voltage, low current device before building a high voltage low current battery.
This is a primary reason for avoiding the particular use of radical elements.
Americium and other radioactive elements can be used which produce less volatile radioactive decay with similar effects.
I once though that if every gram of radioactive waste were properly utilized, we would have no use for their storage facilities - the elements would be utilized from cradle to grave, so to speak.
The device pictured above looks as haphazard as it gets!
There's probably enough radioactive waste in America to power America.
I just realized that solar panels are a cousin of nuclear batteries. When reacting to sunlight, the material temporarily loses electrons...
Maybe there is a way to make a hybrid material that is radioactive as well as photovoltaic. Maybe it would even react greater to the sun's power...
Or maybe not...

If you give attention
and understand this
BOTH ARE THE SAME !!
The difference is:
The patented one
ist "stranger" forced, with an low power 300Mhz Oszillator (small transmitter)
to force the radiation of the "nuc-probe".
The NEW-one thas was published here. is the same, only that the
oszillator is replaced with an self regenarating Oszillator trap (forced by the nuc pobe)
I am sure that will do mor problems to find the harmionic frequency to start this . try the patendet one.
i think that was also discussed here in overunity.com 2006 or 07
with pictures of an finished device (as shown in patent)
So that the "new invenbntor" was surpriced, that i let also shon this
50 years old patent. (i belive - not sure) that this was used for
satellits- power supplies)

Thanks for posting Nali2001. What is alpha decay frequency that urianium ore core is emiting? I cant find that .. nor I can clearly see what are the cap values..
