I don't think so...

First the claim: a consumer submarine that can dive to 37,000 feet.  Or a pressure of over 16,000 psi.

Yeah, right.

The "Deep Flight" winged submersibles are experimental prototypes designed to dive to depths of up to 37,000 ft -- almost four times as deep as a giant squid dives -- descending at 400 ft/minute.

They are the brainchild of submarine designer Graham Hawkes who is in the process of building commercial models that can reach those depths.

Hawkes has been designing submarines since the 1960s, working initially with the British Special Forces and then for the oil industry.

He now sells his designs to wealthy sailboat owners as the ultimate yacht accessory.

"If you have the money for a mega-yacht and you're just limited to the surface, then what a waste. That's my perspective," Hawkes told CNN in a telephone interview.

The late billionaire balloonist and adventurer, Steve Fossett, commissioned one of Hawkes' experimental prototypes, "Deep Flight Challenger," which can dive to 37,000 ft. The craft was four weeks away from delivery when he died.

Venture capitalist Tom Perkins has ordered one of Hawkes' first commercially-available models, "Deep Flight Superfalcon" for his yacht "Maltese Falcon." The $1.5 million sub is capable of diving to 1,000 ft and comes complete with air conditioning. [More]

It's really hard to build stuff to hold back 7 miles of water.  The idea some plastic bubble would work is idiotic hard to believe.

You go first.
