Just got v14 lite for our car last night(SOTA). First impressions are very good as it drove into our driveway itself and backed into a driveway of a house we're visiting. Simply entered the destination address and the car did the rest. Amazing.

Mount them vertically on a north south axis using bifacial panels. Remember that the maximum December sun angle for most of populated Canada is 23°(Toronto) to 13°(Edmonton) above the horizon.

Coal is still king and will be for some time. Also capacity is not the same as production.

The car market is moving from EV early adopters to early majority. The transition will take time to work through the chasm between the two. New models, more charging solutions, longer range, lower cost, EREVs, etc will make the passage across the chasm possible.

The government money is part of a larger initiative, 'Launch the North' by DND. This appears to be the first tranche. Hopefully future tranches will be dependent on engineering and external funding goals being met.

Brent has broken out to the upside of its $100 trading range. The implication being that the market believed for while the Strait of Hormuz shipping issues would be resolved. At $115 market sentiment has turned negative.

Buried in the announcement was a tiny amount of funding for 3 Canadian startup rocket companies. The front runner appears to be Reaction Dynamics; however their technology of using plastic pellets in a 3D printed engine is unproven and lots more funding is required. payloadspace.com/canadian-lau...

That said New Flyer will face a number of technical challenges. For example compact busses could become very popular as autonomous buses go mainstream. Here are compact Chinese buses in Albuferia Portugal.

Investors are very skeptical of building a new pipeline that needs to operate profitably for 40 years starting in 2035.

The economic case for a new oil pipeline coming online in 2035 with a 40-year lifespan may not be good.

My hope is when all Canadian can becomes available it is the world standard 500ml size instead of the US 473ml.

City of Ottawa doesn't close main streets, like Hazeldean, during construction. Now sidewalks, on both sides of the street, sure. Speaks volumes to the city's priorities and its attitude to pedestrians.

You might want this post on X to be real. In fact Karoline Leavitt says some pretty outrageous things but this is not one of them. It is fake.

Not actually true. This is simply an accounting trick. Wind power has produced the same amount of energy than what's been consumed by trains. When the wind doesn't blow the trains will be powered by other sources, mainly nat gas and coal generated electricity.

Tariffs will be fine as the world's airlines should be happy to pay more for a 787 Dreamliner.

Trump, you don't have the cards as a significant amount of the US's massive $36trillion debt is held by foreigners including Canada. Oh, you are also in over your head playing bonds with prime minister who was a 2 time G7 central bank governor. www.wallawallademocrats.com/other-voices...
