This is the only photo of the Flash truck I can find online. Hope to find more to help guide my restoration project. Please send me any leads you might have.

Also, I think we can agree that it's cool to see the best selling American EV truck from today towing a prototype EV truck from 1998. It's like paying homage to your ancestors.

To demonstrate their technology they built a fleet of about 400 Solectria Force vehicles (based on a geo metro ) in the 90s. Lesser known is that they also built a number of EV pickups, which they called 'Flash'. At first they built them based on the Daihatsu hijet and later based on the Chevy S10.

This one is in a little rough shape (for now), buts it's also a piece of electric vehicle history. In the late 1990s, Solectria (long before they were a solar inverter manufacturer) was developing and building EV powertrains in Wilmington, MA.

I've had a thing for Japanese mini pickup trucks (Kei trucks) almost as long as I've had a thing for EVs. Imagine my delight when I heard about an in opportunity to get my hands on an electric Kei truck here in New England.

Congratulations to the Arlington Pumahs! But 'Lady Godiva' Death or Glory' 'Brute squad', 'Ironsides', 'Zoo Disc', 'Rude Boys ' and others I've forgotten might take some issue with the headline writer.

Can't find the original report anymore, but I did find this screenshot. I think it was done by Cadmus. And I was wrong, it was more like 10 years ago (time flies).

My experience is only with cold climate models, but they all have similar requirements. Here is a snip from the Mitsubishi manual. Note that it involves three separate evacs and the third has to be held at <500 microns for a minimum of an hour.

These are what RMI calls 'customer services' and are only available when storage is BTM. That doesn't mean BTM is always the best place for ESS, but worth noting that Value goes up (as does cost) as you get closer to grid edge. Question is which goes up faster.

Every time I read one of these stories I think of Buckminsterfuller's Dymaxion house and Lightful tower, which he proposed could be delivered by zeppelin after dropping a bomb to form the foundation.

This is the #blockchain business I am most intrigued by. You can buy both concrete blocks and chain link fence in one place. I should never have doubted those people who said this would be transformative.

It's older but I know the heat pump program evaluation that efficiency maine did in 2017 asked this question. They found a very small number (5%) of heat pump users were using HP for cooling only. www.efficiencymaine.com/docs/HESP-Ev...
I don't know if they've updated that report more recently.
