The direction of change in a reaction depends on the combined changes of entropy, heat of reaction, and temperature. If this is expressed as ∆G=∆H – T∆S, what would it mean if the value for free energy (∆G) is zero
A.The reaction is spontaneous
B.The reaction is in equilibrium
C.The reaction isn’t spontaneous
D.No reaction is possible

I am doing a project on thermal power. I need a substance which can retain heat fot long periods and can be used to produce steam when wound around a water tube. CAn some1 help me? I have heard that liquid sodium is useful. Is that true. If so how do we get it?
Please dont answer that it is a bad idea. I dont ask what you think about the idea. If you like it you are welcome to tell me, BUT my main QUESTION IS…… WHERE IN US do we burn bio-waste for heat and electric power production?
I know the forest industry burn some bio waste to produce heat, but that require 24 hr demand on heat. In Sweden, they have a big forest industry, and there is popping up bio waste electric power plants all over, very clean, no pollution. Even cities are heated with under ground hot water from these plants. They even store excessive heat in huge thermoses, to be used on peak hours on the day.
Here in western Washington, forestry businesses burn their logging bio waste out in the forests with no filtering or cleaning at all. Sawmills transport raw milled lumber hundreds of miles to get it dryed, instead of power their own drying facility with bio waste, bark and sawdust. Then transport dried lumber straight to the port with less pollution from diesel usage.
I saw a home built by students at a Florida Univeristy that was completely energy efficient. Heat and cooled by solar power. Looked like a home from an alien planet but really liked it. Would like information on how to obtain information about possibly manufacturing this type of home or options to franchise this type of home.

my gecko is female and i got it like a few months ago it was eating for 2 weeks but it stopped. it was eating from every 2 days to a few times a week to nothing i have but 2 crickets in a day and they just stay there for 2 weeks and die. so i tried mill worms again they died so i thought it was the heat so i tried the cal-sand stuff and the temp was better but i still didn’t see it eat but there is stuff around the cage so i know its eating something. it does move around but not much its always hiding and i do sometimes see it drinking the water. its 1 gecko in a 20gal cage with 1 heat rock and a water dish during day its around 85 to 90 degrees but at night i cant control it no money but it gets around 75 to 80 degrees
energy is stored in any object. releasing it can be the trick. now if 500 lbs of lead is pressing against a spring that is just keeping lead from touching the ground, the spring is exsorting energy keeping the weight up. The energy in the spring can and should be able to be measured, as some type of heat, or measure the atoms that are being compressed. even if you could collect any energy from such a experiment you could use it for switching something Electrical or as a signal. it is energy. correct? it should be also free. Incress the weight, more energy. thanks for all input. Dave
Can I use this energy for any purpuse?. And once the weight is on the spring and it remains stable, thats what I want to use. it should remain usable for a long time, and using the right matereal it should last forever, being Relative.
and again, sorry, do you think that there is any energy In between the coils?
I think, that there maybe energy in between the coils. I just need to find a way to measure it. Maybe it has been tried, if so I would like to know, if not is anyone ever tried to measure such a test.?
