This. We have electric engines pinned down. All that's missing from unlimited application of energy is better batteries and better power generation. Look at it

This. We have electric engines pinned down. All that's missing from unlimited application of energy is better batteries and better power generation.
Look at it this way: Human endeavor consists of intelligent application of energy to mass. One of the three elements are close to being made trivial! It's very easy to get excited about batteries and renewable energy!
- baq 12y agothis is not that simple. the article claims that density is similar to lithium batteries, but it doesn't say what kind of density is it. the fact that it charges 20x as much may mean naught if it holds 1/20 energy per kg or per liter.
- barrkel 12y agoDirect quote from the article: This unique battery offers energy density comparable to a lithium ion battery I have no idea about how credible its claims are.
- StavrosK 12y agoWhat do you mean "what kind of density"? "Similar to lithium batteries" means just that, if you have a lithium battery of a certain size, this will hold an amount of energy similar to that.
- Tuna-Fish 12y agoEnergy density can be given in terms of mass or in terms of volume. In general, if a source of a new interesting battery technology does not describe which one they mean in a comparison, you can assume the worst, that is, that they are comparable to lithium-ion in joules/m^3 (at which lithium ion isn't actually that good).
- marvin 12y agoA 30% difference would still be classified as "similar", but this would still be a big deal since batteries are just borderline capable to provide electric cars with sufficient charge to be acceptable for most people. A battery that's 30% worse than the best current batteries would be unusable.
- selectodude 12y agoA car that could charge in 5 minutes and go 200 miles would be as useful to me as my current car. It's a start.
- ctdonath 12y agoHe's referring more to a car that could charge in 5 minutes and go 60 miles. As I have an EV, that's closer to my current scenario of charging (once they put in a charger in the office parking lot) 4 hours and going 90 miles. The tradeoff of reduced distance for superior charge time is...irritating.
- selectodude 12y ago60 miles would be just short enough where I would need a gasoline car. That's why I've yet to get a Leaf. Can't afford a Tesla (nor do I want/need a car that big).

- tormeh 12y agoI meant about the space in general. Sorry about the confusion. I've edited my post.
