An interesting analysis compares the climate change impact of subsidies for e-bikes vs. electric cars and SUVs. It’s true that an electric car replaces more gasoline-powered miles. E-bikes are a lot less expensive, though, so smaller subsidies are needed to encourage purchases. The bottom line, comparing proposals in Maryland and Washington, DC, is that electric car subsidies cost about $4.42 per displaced gasoline mile, while e-bike rebates cost about $3.10 per mile. Though this study doesn’t mention it, e-bikes are also likely to primarily replace short trips, for which gasoline vehicles are less efficient. 

Analysis: E-bike subsidies are more cost-effective than EV subsidies

When it comes to reducing gasoline-powered travel, what gives states the most bang for their buck? David Edmondson finds that e-bike subsidi

The Volta Foundation is a trade organization for battery professionals. Their annual report is a good look at the state of   the battery industry, looking at technology, supply chain issues, and more.

Elsewhere in the battery world, researchers at Tokyo University of Science have been looking at alternative cathode materials for magnesium-vanadium batteries. Magnesium is attractive because it’s more abundant than lithium and offers better energy density, but so far its cycling performance has been unreliable. In their latest results, they appear to have identified a highly stable alloy with superior charge-discharge properties.

Mg1.33V1.67−xMnxO4 (x = 0.1 ∼ 0.4) was successfully synthesized using a solid-phase method under a high vacuum condition for the first time.

In buildings, natural light is good, but solar heating can be bad. Electrochromatic windows can become more or less opaque in order to balance the two, but they are expensive and have a limited operating range. As an alternative, engineers at the University of Toronto have demonstrated a prototype microfluidics system inspired by squid skin. Pigments or particles flow through an array of channels, changing the wavelength of light that can pass through the window.
