Tricycle Machines Mail

I have been using this design for more than a year without any problems. The charger is installed in the battery box, under the seat of the tricycle. To charge the batteries, switch S1 is switched on along with the charger.

This charger does not dry up my batteries, since peak AC input to the rectifier is 187 V. I have tested this tricycle on various roads, and it has...


Vegetation can be used to induce high and low pressures when building design cannot. Figure 7 illustrates some specific building treatments that are effective in fostering passive building ventilation. The important concept here is that even under moderate wind loads, there are pressure differentials on the outside walls and roof of the structure. If the designer takes advantage of these, it is Vent windows placed high on the downwind wall allow negative pressure to extract hot air from inside....

Position of the sun in the sky at noon on winter solstice, lowest seasonal travel North porch is shaded from the sun at its most extreme northern position Maximum amount of south wall exposed to winter sun. This exposure is a compromise to allow for a reasonable 3 ft. roof overhang, rather than the 5 ft. 2 inches necessary to shade the entire wall. A 3 ft. overhang will block sun from shining in the windows at noon during the warmest time of the year. Base of wall All angles are drawn from this...
