Regenerating electricity by braking is appx 40% eff. (according to jurassictest,ch) accelerating electricly is appx. 75% eff. Friction and aerodynamic losses are about 12 kwh pr. 100 km (Leaf 2013 figures). That's not counting heat and air conditioning. Then calculate power additions from solar...
This is likely a stupid question:
If an object just inside the Hubble-sphere is traveling at a speed relative to Earth of 99% of lightspeed away from us, will the light it's sending towards us be at lightspeed or 1% of lightspeed?
Last time we discussed this, we weren't allowed to say suck... I probably missed the train here, but I'll post anyway.
I just wan't to agree to rcgldr and Andrew Mason's statements that there are forces that pulls the boat backwards. There is a low pressure volume behind the boat, caused by...
I was on a treatment on excemption from approval, for a while. It seemed to work, but my ass got fatter, and it was expensive, It supposedly reduced di-hydro-testoterone-levels in head-skin.. "Pro-pecia" it was called. I don't rememer who made it, but they would have made some money.. I decided...
That's an Ikea synthetic nano-throat, not a real organ with living cells. I dear say not quite organ-like, as questioned. Some road to be paved, I expect. Not principally impossible, though pig organs may be more realistic, for now.
It would be nice to find some recipy for making good music through structure and method. That has been attempted, and it has failed. To make good music, I think it requires musical iq/genes, inspiration, and experience. A methodical appoach may be applied in the production-phase, though, to...
Windmills and solar are actual contributions to future electricity solutions. They are much smaller, and require a vast reduction in total consumption, if they'ra going to replace fossile and nuclear. Hydro will buffer solar and wind on the grid. Artificial hydro-drops will possibly buffer some.
Slapped in the face by definitions, once again. I don't like trick questions too much. A question making my answer correct, would have been a considerably better question. Apologies to Chrismartin33 for my conclusive descriptions. And thanks to ehild for explaining the question in terms that...
