  • We already do this at every steam based power plant in the world (basically everything but hydro, PV, and wind) and it’s done much more efficiently. Doing this stuff with tiny gadgets on micro generators like ICE vehicles is a pretty inefficient implementation, especially as it adds weight to already heavy vehicles, decreasing efficiency and safety, and increasing tire and brake wear. The only place I can imagine this being useful is very heavy vehicles that for some reason still have to be using diesel like long haul trucks/busses, diesel freight trains etc and the like. And EVEN then you’re looking at major issues with economy. If you increase the weight of a truck by 2 percent to give it a 2% increase in fuel efficiency, you are hurting not helping. 2% comes off of your GCVWR margins and suddenly you need 51 trucks instead of 50 trucks to transport a given load, not only increasing your fuel use by 2% but also increasing vehicle maintenance and tire and brake pollution by 2%

    Edit: I’m not saying relatively miniaturized energy recovery systems don’t have a future, but I’m dubious it’s in transport or handheld devices. At least for the foreseeable future. Infrastructure scale however has always been a major application for energy recovery development, stirling engine, steam turrbine and TE development keeps getting further pushed to eek efficiency out of power stations, power plants, substations, emergency generators, maybe even HVAC systems and other building scale applications.



  • The SSN is supposed to just be a number that you give your employers and the IRS so that your social security (the USs blanket retirement savings/pension system) contributions get logged correctly to you and then when you retire you can use that number to get the social security benefits that you paid into. The number has ended up being used for all sorts of things because the USA is slightly broken because it is SORT OF a unique ID number for each US citizen, except of course that it wasn’t intended to be that, SSNs are only supposed to be used from first social security contribution (first paycheck) to last social security payout (death) so naturally they can just be recycled.




  • So to answer what I assume is going to be the most common question here, this is a circuit diagram, but every neuron is like its own little programmable integrated circuit with a small amount of internal memory and those aren’t mapped here. So this is an excellent model to explore how neurons connect to each other and get insight into cognition and the function of the brain but it is far from something that can simply be simulated on a computer.







  • You are misunderstanding the confusion, Kwh is an absolute measurement of an amount of power, not a rate of power usage. It’s like being asked how fast your car can go and answering it can go 500 miles. 500 miles per hour? Per day? Per tank? It doesn’t make sense as an answer.

    Does your computer use 100 watt hours per hour? Translating to an average of 100 watts power usage? Or 100 watt hours per day maybe meaning an average power use of about 4 watts? One of those is certainly more likely but both are possible depending on your application and load.
