Awesome, Unique Design Makes this Lock Un-Pickable

newtboy says...

No it doesn't at all, if you spray the liquid where the bar meets the tube, there's plenty of space to get it in there right onto the part that does the locking...then one good hammer blow and that's my bike! It's only the lock bar, not the entire mechanism that needs to break, and you have direct access to it where the bar penetrates the tube.
It also looks like you could easily spray into the slot below the 'keyway' onto the lock itself...and there would be way more room inside to fill with liquid. Worse, it looks like the end caps are anodized aluminum, which won't even need a liquid, just a good hammer! (maybe that's wrong, but it looks that way)
Neat lock, but totally breakable....like just about any lock. A better plan might be a lock with a temp sensor and wireless to alert you theft is immanent.

Normal U-Locks with accessible Key holes are way to easy to break. Just spray lots of liquid air into the keyhole - this freezes the lock mechanism and one-two hit with a hammer and it falls apart instantly.
(some people also use liquid Nitrogen)

This design protects against that.

Power Japan Plus - Dual Carbon Battery

aaronfr says...

Tell an engineer that you want a battery that’s powerful, safe, reliable, and cheap, and he’ll probably respond, “Powerful, safe, reliable, cheap: pick any two.”

It's "dual carbon" because both anode and diode are carbon. It is still a lithium ion battery, but it is much cheaper because most lithium ion batteries today use rare earth metals that are hard to mine, very expensive and difficult to recycle/dispose of.

So this battery might be cheaper and safer, but jury's still out on powerful and reliable.

But didn't the video say the 'electrolyte' was still made of lithium ions? Maybe I missed something?
I want it to be a real, cheap, stable, eco-friendly, powerful battery, but I have to wait to see it for sale and in action first.

Samsung Galaxy S5 - Hammer Test Fail

cegli says...

All lithium batteries can do this if hit with a hammer. Break the separator that keeps apart the cathode and anode and it will short circuit, resulting in it trying to release all of its energy at once.

To avoid this, don't hit a charged battery with a hammer.
