We added a pedal-assist ebike motor to our camp's quad bike (2x2 tandem; 4 passengers). The high Ah capacity was to support using the motor and accessories (atv soundsystem, lots of "dotstar"-style LED strips) periodically th

Like you, I built a similar system for BM this year, but based it around two 48v Li-ion ebike batteries (550 Wh and 1000 Wh). BMSBattery (China) sells a 48v 30AH Lipo battery pack [1] for $530 + $120 shipping, with delivery in 2-3 weeks. Th

Ditto re: battery capacity. Using all 35 Amp-Hours repeatedly will destroy the battery. Anode terminals dissolve during discharging. They are electrolytically plated (thickened) during charging. So repeated full-discharging can reduce their

Hypercomputers: "Perhaps the best known proposal for a hypercomputer is due to Mark Hogarth (1994, 2004), who developed an idea of Itamar Pitowsky (1990). Relativistic hypercomputers exploit the properties of a special kind of spaceti

Some amusing quotes: "A closely related problem is that of distinguishing between physical systems such as digital computers, which appear to compute, and physical systems such as rocks, which appear not to compute. Unlike computers,

More interesting: "wealthier" person gives 1/2 their wealth to "poorer" person every turn. Probably looks like Boltzman distribution describing velocity of ideal gas.

Wow crazy. The article ends by speculating that activities that activate “heat shock protein” pathway may help blood sugar control. It’s interesting b/c this pathway is well-studied in microbes like e coli and we were taught about it
