/

Confirmed by German government tests. This is the same one that broke the distance record for an EV some months ago. All of this is at an average speed of 55mph. Cycle life is 10 years assuming daily depletion to 0 and max recharge rate is 5 minutes provided access to a high current charger.

This is it gentlemen. We've finally made serious headway towards affordable, powerful batteries. Cars aside, this would mean every home could choose when to consume power based on rate. Negotiating power not just with gas companies but with the local utility as well. Something as simple as cheap, potent personal energy storage is gona be as disruptive as computers and the internet put together.

now sit back and watch as this gets squashed by oil company interference

it wont catch on in the states, they think electric is "fer pussies"

it wont catch on in europe, the advertisements wont be effective

asians will ignore it in favor of domestic vehicles

in 30 years we'll look back as the first successful full electric long range cars are being made and say "oh huh, i guess it has been around for a while after all"

Hydrogen is a poor energy storage medium for reasons not commonly advertised by its proponents. The shortcomings of hydrogen are a big part of why we went with electric instead.

That isn't the main problem. With engine powered hydrogen cars it's the lower energy density of hydrogen paired with the paltry 15% efficiency of internal combustion engines. With fuel cells it's the short lifespan and high cost. Fuel cell vehicles top out at 300 miles, and the Model S already does that for $75,000 versus $88,000 projected cost for the first FCEVs. Now that super cheap batteries with 400 mile ranges are here fuel cells don't make any sense.

The water car is a common investor scam. It's just an electric car powered by a fuel cel, which gets hydrogen from an onboard water tank, where electrolysis is powered by a battery.

So you take the energy from the battery, lose half of it in the electrolysis, then lose half of what remains in the fuel cell, and what's left powers the motors. It's an electric car powered by batteries, but with an unnecessary conversion to chemical energy and then back to electrical energy in between the battery pack and the motors.

If it worked, remember that the exhaust is also water so you could just pipe it back into the fuel tank and it would never run out.

Just like compressed air cars it will run long enough for a test drive, which is long enough to fool an investor.

>Evidence has been presented.

"Evidence" my ass. Read OP's article. It was based on an interview with DBM Energy’s Chief Operating Officer, Markus Röser. That's not evidence, that's just trusting someone's word.

Even the writer of the article was skeptical.
"If reports we were given prove true"
"Bold claims, you say? We agree, but will tell you what we were told:"
"According to DBM Energy’s Chief Operating Officer, Markus Röser"
"DBM Energy said it has proven its amazing assertions."
Here the writer reports only on what another writer reported: "According to The Hydrogen & Fuel Cell Letter, an English-language, subscription-based publication Röser sent PDF copies of, last month Germany’s federal agency for materials research and testing – BAM – independently certified DBM’s KOLIBRI battery after a series of eight tests. These were reportedly done" The writer didn't see the results himself.

And finally: "More proof will follow with the next tests, Röser said." Where's the follow up?

I've read a lot of articles like this. Company's make bold claims but rarely follow through. Like EEStor.

>“The KOLIBRI technology has run in forklifts for two years – very efficient,” Röser said, “We already delivered 15 batteries for forklifts in 2010/ 2011 and further orders are already placed. The companies we are working with are large logistical companies running warehouses like Papstar, a subsidiary company of Swarowski.”

lolno.
Firstly, the idea that you've got negotiating power with gas companies is pretty damn amusing. Most of the gas stations in existence are all parts of a local-level monopoly of a single fuel distributor and distributors rarely ever cross into one another's territories.
Secondly, what about this battery says it's cheap, because it would have to be stupidly cheap for the cost of putting them (one of these suckers won't be enough to power a home), and a rectifier into a home and have it somehow cost less than just purchasing at Peak Season-Peak Time rates--not to mention, you've just put two very lossy elements into your power flow, so you're going to be using a lot more input power just to stay at the same output power. Moreover, having to replace them every decade or so as well?
Additionally, electricity is produced AS it is used and many companies can easily go to a moment by moment pricing structure. A bunch of people attempting to game the system by only trying to get electricity during off-peak times would cause *major* issues with the production side, most of which would end up pushing the cost of production way up.
