Finding someone lost in the ocean is a huge challenge but wouldn't we expect a boarding team to be well prepared for this sort of thing? Don't they carry locator beacons, radios, flares or super-bright strobes, etc...? It seems strange that they could not find them doesn't it?

Hopefully this will just get better and better as charging networks improve, as batteries improve, and charging technology improves. We're already seeing some good steps in all these areas.

This is such a really important comment. I feel like so much of our discourse as a society suffers terribly from overloaded and oversimplified terminology. It's impossible to have a useful discussion when we aren't even in sync about what we're discussing.

That's kind of handy as a simple display/browser sanity test. It's very easy to see little processor hiccups on a busy machine.

Low-power is great but running a big RAID long-term without ECC gives me the heebee jeebies! Any good solutions for a similar system but more robust over 5+ years?

This is where I need to be eventually. I'm hesitant because I'm worried that I won't find any competent installers in my area and I'll end up with leaks, polluted well water, etc... Any troubles with the ground loop so far?

PGPR is polyglycerol polyricinoleate -- an emulsifier made from glycerol and fatty acids. It's used to modify the flowability of molten chocolate and is typically less than 1/2 percent of the chocolate mix. If a company is using more than that the chocolate probably isn't going to harden... It's one of the hundreds of "mostly harmless" additives you see everywhere these days not a filler. Whether all these additives are really ok once you put them in every single thing has yet to be seen.

I think the algae is great but this also shows how very, very little power you need for small embedded devices these days. You could probably run this CPU off of almost anything. Moldy old pop tart? Go for it!

From the paper:

"Throughout the test, the Arm Cortex-M0+ processor drew an average current from the compact Al-BPV of 1.4±0.4 μA with a voltage of 0.72±0.14 V. ... As the average power drawn from the compact Al-BPV during the 27 weeks of experimental run (1.05 μW) was larger than the minimum power required to run the CPU (i.e., 0.3 μW), it is likely that a smaller power-generating system could be used, or that more computationally intensive algorithms could be performed."

and:

"We programmed the Cortex-M0+ CPU to calculate a sum of consecutive integers as an example compute workload, and assess the correctness of the computation by verifying the sum against a precomputed value."

Pretty neat -- although it looks like they were clocking the chip at only 10 KHz.

Marketing says we'll make a fortune with ads on a big screen! Plus we can upsell related products and charging packages!
