Jet fuel has no lead, it's basically kerosene. Avgas for reciprocating engines (basically only small general aviation planes/helicopters) currently contains lead but is moving to be lead free in the US.
I think this is a bit of a pedantic take. My reading of the GP is to distinguish systems based on chemical batteries from systems based on gravitational batteries rather than the reaction time of the chemical cells specifically.
Also have to take into account that number was at ground level where there is the highest air density. I’m not sure what the landing and takeoff profiles looked like in the design but presumably the wings are that size so it can operate at a higher altitude at a reasonable speed.
Sorry poor terminology use on my part. I mean more broadly that most energy is used on frontend and middle end, rather than backend and that this is what vectorisation improves in regards to energy consumption. Register renaming and branch prediction energy consumption should be improved in the same factor as decoding. Caching probably less so (depending if we are talking instruction, data or combined).
I don’t think inter-core communication is too relevant when comparing vectored and non-vectored on a single core, but definitely would be when batching across multiple cores.
Wouldn't that support the idea that most energy consumption is in decoding? If you're getting 2x, 4x, 8x ect as much value computation per instruction and yet only a 30% increase in power then clearly most the power is not used by computing the values.
It’s true this is as good as resistive heating in terms of heating efficiency, but it is still far less efficient than a heat pump. Unless you are in an area with a large excess of renewable energy it probably doesn’t make sense environmentally to use an asic heater.
For some two-way wireless protocols (like wifi) you have to take into account the guard interval, slot times and interframe spacing which are all values set in time (~1-50us). For long distance transmissions your speed-of-light limited signal propagation time can exceed these values.
In terms of size usually guard interval < slot size < inter-frame space. If propagation exceeds guard interval AND have a channel with lots of echo any communication will be difficult. If propagation exceeds slot timing then coordination between more than 2 devices will be different (high retries/low throughput). If propagation exceeds interframe spacing a two-way wifi connection will not be possible as both stations will think every frame timed out waiting for an ACK.
