can if u keep on reheating...but illogical to do so. the laws of thermodynamics already tell u its not possible....Originally posted by caramon:Last time the idea of sound coming out from computer is crazy.. if you think it's
impossible, then it's really impossible..![]()
if u can make a thermoflask dat keeps things warm for months u can make some $ provided u dun need any power supply or energy sources to generate the heat but it won't make u rich.Originally posted by gentlerock:Already invented what, but need power input lor. Just get any electric kettle (the plastic type which also acts as a thermos)....and carry it with you. Everywhere you go, just plug it in lah. Wall plugs are not uncommon nowadays what....everywhere also got.
My question is.....why would it make lots of money? Is there any market demand for keeping water hot for months?
oh yeah toking dun need effort one. u can say all u wantOriginally posted by caramon:It's feasible.. I don't have the time, so I had to let this idea go.. grab it fast..![]()
yah, we all know dat, remember our burning planet sun ?Originally posted by dzylim:will never work in today's technology. radiation will happen and heat will be lost.
Just in case war comes and they bomb the power stations and water pipes....then you are hiding in the bomb shelter for months and suddenly feel like having a cup of Nescafe.Originally posted by mistyblue:when I need hot water, I just boil...
Why do I want to drink hot water kept for months?![]()

at least old man still wants me...Originally posted by shade343:I tell you how to make money lar...go find SMAP catch him, and sell him to old man
Then I better keep a tub cause I like to soak in hot water...Originally posted by gentlerock:Just in case war comes and they bomb the power stations and water pipes....then you are hiding in the bomb shelter for months and suddenly feel like having a cup of Nescafe.
Wah Kaoz,THERMODYNAMICS leh... I am having problems with this module.Exams in 2 months time and i realli dun know a single thing...Originally posted by chunyong:if u even know the basics of thermodynamics and heat transfer u will know its impossible....dats why we are stuck at cars which only fruitfully uses a small fraction of the energy given off from the fuel. if only all things are adiabatic.
study hard lah....spending too much time talking to urself #1 and urself #2 here is no use one.
I don't want to drink stale waterOriginally posted by caramon:A flask that can store hot water for months.. You will be rich if you can invent it..![]()
aiyah, will moderate one else how i pass ? hahahaOriginally posted by tRiAgE:Wah Kaoz,THERMODYNAMICS leh... I am having problems with this module.Exams in 2 months time and i realli dun know a single thing...
yah....people without gray matter then will invent such stuff....Originally posted by mistyblue:when I need hot water, I just boil...

its secondary sch sci, its impossibleOriginally posted by caramon:A flask that can store hot water for months.. You will be rich if you can invent it..![]()
there is even a cup or vessel dat can do the same, just use a thermostat and source of heat and lots and lots of fuel/power supply.Originally posted by Omega-broly:is there really a flask that can store hot water for 1 month?
Not yet.. but I am sure there will be one in the near future..Originally posted by Omega-broly:is there really a flask that can store hot water for 1 month?
