AI Thread Summary
Recent discussions highlight that while biodiesel and ethanol are well-known alternative fuels, hydrogen and natural gas are also significant contenders in the market. Technologies like ultra capacitors are being developed to store energy more efficiently than traditional batteries, showing promise for future energy storage solutions. Biodiesel is noted for its comparable efficiency to conventional diesel, with improved emissions. However, specific efficiency rates for newer alternative fuels remain unclear. Overall, the conversation emphasizes ongoing innovation in alternative energy sources beyond biodiesel and ethanol.

Does anybody know what's the most recent alternative fuel that has come out beside Biodiesel pro types and Ethanol.Or what the efficiency rate of this fuel is?

Well, none of the technologies are actually 'new', with the possible exception of biodeisel in a picky way. The other major ones being looked at are hydrogen and natural gas. Sorry, but I can't give you any numbers.

Some people are working on Ultra Capacitors that can hold a lot more energy then a battery, even better then EEstores Ultra Caps.

What are capacitors in detail ?
I don't get how two plates that aren't in contact are able to store high voltages.
 
as far as efficiency, biodesiel i hear is similar in efficiency to convetional diesel, but just better when it comes to emissions
 
Thread 'Is there a white hole inside every black hole?'

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Is Gravity an entropic property like Surface Tension'

Why do two separately floating objects in a liquid "attract" each other ?? What if gravity is an emergent property like surface tension ? What if they both are essentially trying to *minimize disorder at the interfaces — where non-aligned polarized particles are forced to mix with each other* What if gravity is an emergent property that is trying to optimize the entropy emerging out of spin aligned quantum bits
