In large power plants, e.g. block D of natural gas power plant Emsland, you can get almost 60 %, but that's neither the standard for power plants, which was like ~28 % in Germany a few years ago, nor is the technology applicable for small scale devices as e.g. car engines.
Like capacity x capacity factor, e.g. if your 100MW site produces power 50% of the time (because of nighttime, clouds, etc) then it would produce, over the course of a year 100,000,000 x 24 x 365 x 0.5 = 438 GWh annually (very simplified).
Yup, typically I just mentally multiply by 1000 (nice round numbers). But obviously a 100MW farm in the Sahara is going to produce more in a year than the same 100MW farm in Germany. It’d be cool to see a list on a global scale that showed a table and maybe generation vs demand curves for the area they serve. Maybe I’ll put it on my “projects I’ll never get to” list.
That graph floating around on how batteries have changed the electrical grid is super impressive. Batteries have to really start eating into base load power this year.
This is good, and hopefully for micromobility, too.
I want my current car to be my last ICE car. But my ebike has been so much easier than driving for downtown activities, I'm starting to wonder if I will even need to drive much at all.
I'd probably still want an EV for longer distance travel, but that isn't necessary for day-to-day commuting.
Nothing about how viable it will be to bring to market, if ever, just discussing R&D without much content.
Potentially always good to see these sorts of improvements :-) Is just not that impactful until they can make it useful. If it's 50 years away from being producible at scale? Eh. If it's only 6 months away and can drop in to existing pipelines? Hell yeah!
Article says 2 250w motors, so I'm guessing Max 30% input from the rider. I've got a 750w ebike myself and know it struggles to haul my 350lb/150kg butt up steep hills, so I wonder if we'll see any of these going backwards down some hills
Semi-trailers (aka what everyone calls a trailer, but full trailers are rarer now) are GOAT for expanding payload capacity for the same prime mover, and to drop the trailer and pick up a new one, improving operational efficiency. We've known this for a century
The description says "cargo-specific brakes" but I hope that implies brakes on the trailer wheels. 350 kg unbraked would be uncontrollable or hazardous if things go south. Yes, this would require a hydraulic brake coupler from cab to trailer, similar to what big rigs use. But seeing as they have CCTV in the trailer, they're already running lines to the back.
This setup is 5 meters long. Are there no mirrors??
Interesting idea. Seems well-suited to urban distribution (eg restocking convenience stores), or as a suburban mobile distribution point, taking up a position to launch smaller bikes for last-mile delivery.
That's certainly plausible. The typical requirement to keep auxiliary/infotainment systems separate from safety systems in automobiles doesn't really make much sense here, so reusing the cameras might work. Still, though, it's not like the air resistance of some extra mirrors would be a huge problem.
I don't quite follow. These roro boxes fit the description of a standard pallet (2 meters cubed, taller and longer than wide), why not just outright have a single pallet shipping container? Or is this a cheeky reskin of a pallet?
