  • My parents drove from Vancouver BC to Barrie ON (4000km) this spring in their new electric car. Their biggest complaint was that Tesla chargers are very difficult to use because the cable is only barely long enough to get to their charging port, they need to position the car within like 2cm to get it to reach.

    Overall it was a great experience, they’re retired and aren’t really in a hurry. They liked the exploration and walking breaks.

    They spent a lot more money in small towns than they did when they drove their Prius.

    Biggest concern is if there were to be a road closure.

    They will be driving back next week.








  • Abstract from Science:

    Storing sunlight in a compact and rechargeable form remains a central challenge for solar energy utilization. Molecular solar thermal (MOST) energy storage systems, which harness photon energy and release it as heat on demand, provide a direct approach, but have long failed to meet practical benchmarks. Inspired by the architecture of DNA, we report a pyrimidone-based MOST system that stores energy in the strained Dewar photoisomer upon excitation at 300 nm. Designed with sustainability in mind, the system operates solvent-free and remains compatible with aqueous environments while overcoming one of the field’s greatest hurdles: the controlled extraction and transfer of stored heat. When catalyzed by acid, the Dewar isomer releases enough heat to boil water (~0.5 mL). These advances help point the way toward decentralized solar heat storage and off-grid energy solutions.
