the vast advances in lithium-ion batteries has now given us…an underwater jet pack that can go 3 meters/second with 40-minute battery life and total 3km range

Was interested in making this part of the Bearly.AI research app employee on-boarding kit (along with a 2008 Thinkpad with thay red button in keyboard).
But just saw the price:

Its $30k. Only for rich folks for now.

Agreed. And probably most expensive…

it’s not cheap!

really cool. seems rather dangerous too... curious about saftey features (e.g., blacked out user; battery dying while out to sea or under water)
It's very heavy ... guess what happens when you strap a rock to yourself and jump into water? They show it briefly, then avoid any shots of trying to get out of the water or just head above water. This will drown people :)
I'll wait for the ROCmjet instead, hopefully it will be cheaper than this CUDAjet
Not everything has to be bombs and wars. Some things are friggin underwater jet packs! 
Is there a polymarket on how many influencers with no scuba certification will buy these and get themselves killed?
Not that much. Very cool, but this honestly is just someone making a product and selling it
Energy storage is single handedly one of the biggest things holding back civilization and industry, lithium-ion has been around since mid-90s. We desperately need a newer tech, big hurdle
I wonder if this could be adapted to extract air from the water, a la gill functioning?
I don’t think it’s that complicated tool. Wouldn’t be too hard to remake. Soon enough you will be bombarded with ads.
how many 18650 Samsung 30Q cells do you think this thing would require
Need a GoPro so I can watch when a great white shark thinks one of those dudes is a seal, that is going to be epic footage 
comments are dumb. this thing is cool. most new tech starts out high priced and gets cheaper later on.
the thermal runaway from saltwater ingress to lithium ion battery will melt your spine
This feels like some research we need to get a startup on, make it commercially viable at smaller scale.
The next jet ski.
I just wonder how many years till it will be halfway affordable, which would mean something around $2000-$5000.
The high cost factor are the batteries only and maybe hq water protection, right?
Waiting for the lithium to meet the water
I wonder how sharks feel about a human looking and swimming like a big fish.
What if you misjudge battery life and end up half a mile offshore with a dead battery
And it only took women and children, slave labor, a whole year to dig the needed lithium.
Someone's math skills really suck. 3 meters/second for 40 minutes is 7.2 kilometers. So which part is correct?
That's wild! Who needs a fish tank when you can zoom around underwater? Just remember to avoid the sharks!
It costs $30,000 weighs 30lbs, and runs for 40m (allegedly) with max range of 3km.
You can get a "sea scooter" that weighs 3lbs, has 1+ hours of battery life, and 4km range for $500.
What advances in lithium batteries are you talking about? The battery leader Tesla has the same range with the same batteries for the last 10 years.
