Does anyone know if there are any substances that can be used/made into a substitute for a battery?
That's my gut reaction, too but the thing that makes me react against Capacitor storage is the drooping voltage and that could be a worry of the past with switch mode becoming cheap and powerful.CWatters said:Shadow-Shocker...What's the problem with using a battery?
David Lewis said:Large value capacitors are sometimes substituted for voltaic cells, e.g. where weight is critical.
The problem with batteries is that they eventually die out due to conventional current. I want to find an alternative form of energy that lasts longer, since the project I am doing will always be turned on, and I am looking for a much higher dense form of energy that will last for years. The battery that will fit within my project, structure wise, is a 9V battery. I was looking at graphene/carbon nanotube substances, since they are capable of being put on a piece of paper and have a crap ton of conductivity. However, those substances cannot be used as a power supply only as a capacitor. The question is, are there any forms of highly condense energy that are tangible/mobile?CWatters said:Shadow-Shocker...What's the problem with using a battery?
Old fashioned fuels do a pretty good job and the engines are cheap. Still a good solution for some applications; you need to do the precise sums for a proper evaluation. If you want a result, it's not always best to get too fond of a particular solution.Shadow-Shocker said:are there any forms of highly condense energy that are tangible/mobile?
What about clean alternative solutions?sophiecentaur said:Old fashioned fuels do a pretty good job and the engines are cheap.

That's a valid question but you could consider how much real impact a simple 'dirty' solution could be, compared with an expensive, hi tech solution that may have had all sorts of impact on the environment before you bought it. There's a lot of snake oil associated with some of the 'clean' uses of energy and it's important to do a lot of sums before concluding the absolute level of cleanliness of a solution.Shadow-Shocker said:What about clean alternative solutions?
What about alternating current solutions, they reduce significant amounts of energy compared to direct current? How can we apply that for a battery?CWatters said:Reduce the consumption of the device? Some smoke alarm batteries last 10 years due to their low power consumption.
Or hell, we can start making better ones instead of waiting.CWatters said:Perhaps worth pointing out that it takes quite a lot of time and effort to get a factor of two improvement in battery energy density. If you want better than current Lithium cells you may have to wait 5-10 years for them to become commercially available.
This doesn't make sense.Shadow-Shocker said:Or hell, we can start making better ones instead of waiting.
Just making an funny/encouraging statement.DaveC426913 said:This doesn't make sense.
You can bet that a better battery has the attention of a LOT of tech companies. Do you think they're just sitting on their laurels and reaping dividends?
5-10 years is how long it will take the best in the world to make them.
Exactly how much energy does it need?Shadow-Shocker said:The problem with batteries is that they eventually die out due to conventional current.

No, they don't.What about alternating current solutions, they reduce significant amounts of energy compared to direct current?
Enough to keep a 6V motor moving forever, or for a really long time.russ_watters said:Exactly how much energy does it need?
russ_watters said:No, they don't.
Well, "forever" would be an infinite amount of energy and since a volt is not a unit of energy and "a really long time" is undefined, I'll say you need 47 and suggest powering it with purple.Shadow-Shocker said:Enough to keep a 6V motor moving forever, or for a really long time.
Well, no offense, but this is a serious forum and if you intend for this to be a serious idea and want real help, you need to take it more seriously.Just thinking of ideas

Minature fuel cells powered by a few drops of methanol hold promise, but turning research devices into cheap mass-market products is staying tantalizingly just out of reach. http://www.techradar.com/au/news/world-of-tech/whatever-happened-to-mobile-fuel-cells-718317Shadow-Shocker said:Does anyone know if there are any substances that can be used/made into a substitute for a battery?
C'mon, you're really in need of tough love and we can be extraordinarily helpful if you help us help you. Nowhere in there did you address the problem I highlighted. So do you want false encouragement or do you want real help?Shadow-Shocker said:Im sorry, but...
I am accepting criticism, and I am letting a lot of people help on this discussion. If you don't want to participate on this discussion and go to another one, that is up to you.russ_watters said:C'mon, you're really in need of tough love and we can be extraordinarily helpful if you help us help you.

I was helping/participating: I did ask you a specific question that would be a big help, but you haven't answered it.Shadow-Shocker said:I am accepting criticism, and I am letting a lot of people help on this discussion.
