Devices with lots of batteries

[James Van Artsdalen]

The January 30 issue of Nature has an article on autonomous submersibles. One is “Autosub” developed by Southampton Oceanography Centre. It is powered by 5,000 standard D cell batteries!

The article states that Lithium batteries would be too expensive. But why not AGM auto batteries (assuming you want to stay off the shelf)? They must be using graduate students or some other form of slavery to change batteries.

Has anyone ever heard of anything like this?

Apperently there are plans for a Mark II...

Maybe they're NiMh and they have 1000 Maha 777s standing by??

Oh dear, I hope they aren't all connected in series.

The lead-acid types may be too heavy. You want those submersibles to come back up sometime.

When Mr. Bulk hears about this donor, you're gonna see one awesome flashlight.

Yes, they are all connected in series, they are to repel giant squid attack and are directly connected to the hull...

It makes sense to me. They probably just modded a 5000 D cell M@glite.
