As of March 4, this robot vacuum and mop combo is down to $299.98. According to camelcamelcamel, this is only $15 away from its best-ever price.
For the Poincaré half-space model in dimension 2, the metric evaluates on the coordinate tangent vectors \(\frac{\partial}{\partial x}, \frac{\partial}{\partial y} \in T_pM\) as \[g_p\!\left(\frac{\partial}{\partial x^i}\bigg|_p,\;\frac{\partial}{\partial x^j}\bigg|_p\right) = \frac{1}{y^2}\,\delta_{ij},\] i.e. the coordinate tangent vectors are orthogonal and each has length \(\frac{1}{y}\) — shrinking to zero as \(p\) approaches the boundary \(y\to 0\), which is what makes the space “infinitely large” near the boundary.

本次发布的闪充桩，单枪峰值充电功率达到1500kW，是全球量产单枪最大功率充电桩。但比功率数字更值得关注的，是其内部搭载的第二代刀片电池所构成的储充一体系统。这套系统的逻辑很直接：在电网负荷高峰时，电池充当“蓄水池”储存电能；在需要大功率输出时，电池作为“功率放大器”释放电能。相同电量供给条件下，单座闪充桩日均服务车辆可达约50台，充电效率约为普通充电桩的10倍。
