According to the EPA, Americans throw away1.6 billiondisposable pensevery year. Add the rest of the world, multiply by over 50 years of writing with disposable pens, and that’s a lot of metal and plastic waste ending up in landfill! I suspect it’s just the tip of the iceberg, given...
the price might be decrease as a result of the metallic sheet will not be hooked up to the constructing and there are fewer components to connect to the construction. Moreover, lighter roofs would require much less metallic to be added onto the constructing. Firms that promote light-weight ...
these fibers are either thermoset or thermoplastic with high softening or melting temperature to withstand potentially high internal temperatures that may exist inside the fuel cells or inside the electronic devices. Filler materials of any porosity or permeability can be used, so long as the filler ...
By contrast, ambient air is essentially stationary until given velocity as it is drawn forward by the flow discharged from the emitter, and in color the computer graphics show this in gradations in cool colors (from dark to lighter blues to dark to lighter greens). In the black line ...
Values below 100 # gradually make the output lighter, whereas values above 100 make the output # darker. The value divided by 100 is the actual gamma applied, so 80 represents # a gamma of 0.8, The value 220 represents a gamma of 2.2, and 100 does not # change the gamma. # Minimum...
Batteries can be built in any configuration you desire, as can motors; for example, long & skinny to fit inside tubes. @suferick, Regenerative braking uses the wheels to drive a generator to recharge your batteries, instead of burning it off in brakes. Typically, the generator is combined ...
