Insane radical idea: Businesses can actually make a profit by having income higher than expenses. You can pay yourself that way.

But why would I waste an extra $5k and floor space in my garage if _I already have an EV that should be able to do this_.

Anyone expecting regular 4+ day outages is already going to have a generator. What people want is for the car which is already plugged into their house to kick in when the power goes out for an hour or two.

The industrial revolution predates Indian colonization. In fact, you have the causality exactly backwards. The British empire could not have colonized India without their force of industry (ships & machine guns)

Integer arithmetic is a significant part of ~every program. A single branch that checks the overflow flag is not expensive. But branching on that flag every time you do integer math is death by a billion paper cuts.

The point is that batteries are many orders of magnitude off in terms of cost, weight, size compared to fossil fuel storage. > Electricity will be like propane, soon. Is not true for any reasonable definition of "soon". Our eff

That website doesn't mention cost, but just the shipping container that houses the battery is going to cost much more than an equivalent propane tank. The battery is quoted at 400kwh, which is 1,440 MJ of energy. That is equivalent to

Just wait until Apple finally removes the lighting port. I can travel with one cable & wall wart to charge every device I own - that's the future.

It would be nice to actually link the source[1] (PDF). The stat is that you lose between 25-40% efficiency for "typical" existing installations. The document goes on to explain that an insulated duct which doesn't leak doesn&

I had a similar problem, but I decided that simply running the fan to mix up the air was a fine solution. The fan doesn't use much electricity, and it's good not to let rooms get too stale anyway. I have the fan programmed to run

Per OP's report, what matters is axle load. A typical garbage truck has 2 or 3 axles. Let's assume 3 to be conservative. A fully loaded garbage truck weighs around 50,000 pounds. That's 16.6k pounds per axle, vs a Tesla Y&#x2

by dahfizz 4y ago
Yeah, that's my point. A single garbage truck is going to do more wear on the roads than thousands of passenger vehicles. Anything besides industrial vehicles is negligible.

Typo, fixed. I could have sworn I typed "couple hundred pounds". But to your point, a bmw 430 is also around 500 pounds heavier than a Honda Accord. Nobody sees a BMW and freaks out about tire wear. But people seem to hyperfixate

by dahfizz 4y ago
Threads like this read like EVs are double or more the weight of an ICE car. EVs are a couple hundred pounds heavier in average than an equivalent ICE car. In terms of road wear, it's still a rounding error compared to industrial truck

Closing gitmo could just as easily be presented as a success. "We won the war on terror, so we don't need gitmo anymore." It's all propaganda either way.

This is less of a "haha FTX so dumb" and more of a "how could that possibly ever hang together for 2 years??"

> Javascript only has floating point numbers – it doesn’t have an integer type. Can anyone justify this? Do JS developers prefer not having exact integers, or is this something that everyone just kinda deals with?

I'm sure the people in charge of the project wish they could snap their fingers and double their budget.

VC investors don't want an all-weather business. And you don't see very many risk-averse investors who are willing to dump their money into startups.

Let's do some basic math: The US average cost of electricity is 16 cents / kwh [1] The US average cost of Natural Gas is $10.84 / thousand cubic feet [2] A thousand cubic feet of natural gas contains around 300 kwh of energy

I have a aux heater that kicks in when the heat pump can't keep up, and I have noticed this. When the heat pump is running, the air coming out of the vents is barely warmer than ambient. Definitely less than 70F. When the aux heater ki

I have a heat pump in New England, and it works but damn is it expensive right now. I think I need to upgrade to a bigger pump. My aux heat is kicking on semi regularly, and the heat pump is running it's reverse cycle pretty regularly.
