| Wind seems to be the least developed option, but it also has the most potential. 8mm aluminium tent poles weigh 100g/m, the above generator is 360g, so there's scope at about 1.5kg. | Wind seems to be the least developed option, but it also has the most potential. 8mm aluminium tent poles weigh 100g/m, the above generator is 360g, so there's scope at about 1.5kg. | ||
| - | Most commercial wind generation is designed to be permanent and have a lot of storage, so it operates best at the average wind speed. That's not what we want here, we want some power at low wind speeds and not to break at high wind speeds. | + | Most commercial wind generation is designed to be permanent, have a lot of storage and operate best at the average and high wind speeds (power as V<sup>2</sup> biasses towards high speeds). That's not what we want here, we want some power at low wind speeds and not to break at high wind speeds. Moreover, varying the pitch of the blades by anything other than bending/stretching is too complex. |
