The quote is saying that transmission line capacity is higher when it's windy and lower when it is windless (due to less cooling). If you assume that EV charging is the marginal load which would put you over the windless capacity, but

As many have noted there are two different scenarios. In the lottery jackpot/UBI scenario where money is no concern at all I'd camp, fish, read books, and drink whisky. In the need a job, but every job will pay my asking salary sc

If you had a serial plug-in hybrid with a 20+Kwh battery which also supported exporting 120vac, that would work. AFAIK such a vehicle doesn't exist in North America yet and might not exist anywhere globally. You start stacking energy e

Charging using the truck would require running the truck all day -- probably not an acceptable alternative. Consuming 2-10 Kw from a 200 Kw engine would be so inefficient that it'd be too expensive anyways. Instead you'd need to r

There is no low hanging fruit when it comes to reducing plastic production or consumption. Plastic is just too awesome -- which is why we use it instead of whatever we used before plastics. I'm not aware of any major use of plastic whe

It feels like a deadline because in many ways it *is* a soft deadline. It is an uncomfortable fact, but at 30 you are about ten years into the productive fifty years of your life. You are about ten years into the thirty years of your life (

We can look at what's happening in Ukraine right now to see how well that's working. The truth of it is that no matter how much technology is deployed land can only be held with infantry. Being infantry is still physically demandi

Not needing a sub-panel is almost certainly the reason. The North American residential electrical code limits how many circuits you can put onto a generator based on the circuit capacity, not the expected use. You aren't allowed to pin

I'm not entirely clear on what your question is, but reused single-use propane canisters are lesser for three reasons. 1. The propane they are manufactured with is carefully dried, but propane out of bulk tanks is not. The single use t

The cheapest way is to find some cheap, food-safe container(s). Put it into your basement and change out the water every 3-6 months. 55 gallon rain barrels can often be found subsidized and therefore cheap. Keep a bunch of camping iodine dr

The losses are different, but still exist. In the L3 case there is still a voltage conversion because the input voltage needs to be higher than the battery voltage in order to put energy into the battery. There will be a loss at that stage.

Among other things, security became a concern. Being lenient is all well and good when the consequences are mild. When the consequences of misinterpreting or interpreting differently to a second implementation becomes costly, such as a secu

It sounds like you almost have enough numbers to calculate the ball-park efficiency. Grid -> condo battery ~85% (basically an L2 charger) Condo battery -> L3 charger let's say ~96%[0] because it's a high discharge rate L3 ch

The road to hell is paved with good intentions. You are right that most trips don't need SUVs and pickups, but many families need large-ish, relatively powerful vehicles like the now dead station wagon. But it is uneconomical for car b

I haven't read the actual bill, but from the news reports it's the former. Right now the inclusion rate is 50%; which more or less means capital gains are effectively taxed at about 27%. On June 25th, 2024 the inclusion rate will

None of the payment mechanisms I suggested do anything of the sort. In fact none of them involve a bank at all. And since the receiver can choose to not cash in the postage, the postage need not be validated at all.

Might makes right is how all land is owned. Always has been, always will be. We've stacked lots of layers of paper and convention on top of that fact to reduce the amount of war we make, but people ignore this basic fact of the world a

I was speaking to my house builder in the middle of 2023 and he noted that it had become impossible to build a starter house (2/3 bedrooms, 1.5-2 bath) for less than $450k CAD (~$300k USD) -- excluding land, utility connection, and fin

Where I live it costs $1500 to create a new corporate entity and $500/year to file taxes for a trivial corporation. A limit like that is entirely unworkable against large corporate interests. All it would do is prevent local, small-tim

The empty homes tax is a joke. It's too easy to bypass (just have somebody you know use it as their primary address and add a few lamps on timers) and priced too low (in many cases the tax is cheaper than the costs of having long term

There's a few things happening here, but it boils down to EV range being just barely adequate so people are dependent on the range estimate and a 10% error is sometime a serious problem. This is especially true if you need to drive in

It would be more thermally efficient, but not as economically efficient. Firstly, consider the capital costs of an engine + natural gas pipeline + heat pump (excluding electrical motor) versus either a natural gas pipeline + burner _or_ a h
