    Except for the blind spots.

    NHTSA says there are over 800,000 blind spot accidents in the U.S. every year, resulting in about 300 fatalities. That's why higher-end cars are coming with blind spot detectors now. Note that Japanese taxis mount the side mirrors on the front of the car to eliminate the blind spot. The image is smaller (boo hoo, you can't read the front license plate), but you can immediately see any vehicles in your blind spot. The taxi companies have found such a big improvement in safety due to those mirrors that they use them even though it looks dorky.

    Everyone arguing that side mirrors are superior needs to come to grips wit the fact that unless you mount the side mirrors on the front of the car, they are simply not a very good solution to the problem. If cameras can eliminate the blind spot, they will be a huge improvement to safety. Any aesthetic or fuel consumption improvement is just gravy - the important thing is the safety improvement. Even the argument that camera viewscreen require a different focus distance can be addressed by mounting a mild lens in front of the display.

    The government by definition has no competition. So there are no disincentives for flaunting security rules since the government can't cease to exist (well I suppose there's popular revolution, but those are few and far between).

    Jones' mistake is that he doesn't understand the economics. Most of the cost of paving a road is not the surface material, it's the labour and the equipment.

    If the marginal cost of making a road a solar road is $x / Watt of installed capacity, and the number of Watt-hours generated over the expected lifetime adds up to a value of $y, and x > y, then the labor and equipment cost doesn't matter. It's never worth it.

    You're demonstrating a fundamental misunderstanding about opportunity costs and percentages which is all too common (and is a large part of how marketers exploit people's purchasing habits to upsell you). That if a cost of an option exceeds its benefit, that you can somehow make it worthwile by reducing its percentage share of the overall cost. i.e. When a product is 100% of the cost, it's not worth it. But if you add it onto another much more expensive purchase, it's now "only" 1% of the cost and that somehow makes it now worth it. Yes the percentage got smaller, but it's irrelevant. You're comparing against an absolute benefit, so you need to use the absolute cost to make a proper comparison. No those floor mats aren't worth $150. But add them onto a $25,000 car, and suddenly people will pay it because it only adds 0.6% to the price of the car.

    You can argue that the cost of a solar road surface is reduced compared to plain panels because the people making the road would be doing the labor anyway, and that it's no additional work to lay down the PV material since (for installation purposes) it behaves similar to other material they're already using to make the road (I dunno, I haven't read up on solar roads). Or you could argue the PV material replaces some other material they're using to build the road, and so represents less additional cost than just the PV material alone. But you cannot argue that it somehow magically becomes worth it because you're tacking on a bunch of other costs (labor and equipment) which you would be paying for anyway.

    Another crucial aspect here is that electricity cost is about 20-35 cents/kWh in Europe, while it's only 11.5 cents/kWh in the U.S. So a solar project that's marginally "worth it" in Europe can be a total money loser in the U.S. (unless you're in Hawaii).

    A really clever system using a pipe buried undergorund to cool air, and a heated air duct on top of the home to draw air out, so the lower pressure would draw air through the buried pipe. The surrounding ground would cool the air as it traveled through the pipe, and when it came up in your home it would be substantially cooler than the ambient air temperature.

    We're starting to adopt the same concept again in newer homes. Turns out dirt tends to stay cooler than the air in summer, and warmer than the air in winter. So you just bury a bunch of water pipes undergorund and use that as your heat sink/source for your heat pump. In summer it cools the home by pumping the heat underground into the dirt, in winter it heats the home by pumping the heat out from the dirt underground.

    Water, sewer, and electric are easy because they're utilities. As a landlord, I only need to connect those up to one system and everyone is good to go. That's not the case for ISPs. Some are DSL, some are cable, some are fiber, some are WLAN. (The DSL is not a problem because it runs straight to the tenant's phone, and switching DSL ISPs is transparent for the landlord.)

    It's the same reason local governments granted cable monopolies - from a physical hardware perspective, it's not very practical to lay down a dozen different redundant cable networks throughout the town just so everyone can pick from a dozen cable ISPs. Likewise, it's burdensome for an apartment to provide a dozen different network connects for different ISPs on the off chance some of their tenants might use them. Especially if it's an older apartment whose "server closet" is just a metal box with a couple 110 blocks and a small DSLAM in it. Most older apartments (and hotels) use internal DSL from their phone box to the individual units precisely because it didn't involve having to install new cable (Internet runs over existing phone lines). And cable Internet works with a single provider because the entire building is rigged up branching off of a single coax cable. But in-building coax won't work with two cable ISPs unless you lay down two parallel coax networks.

    I just finished installing ethernet to the individual units of the building I co-own (commercial property with a dozen tenants). It was a PITA installing new conduit, and for how much it cost I won't see a return on investment for over a decade. And I got it done fairly cheaply because I did it myself. If I'd hired someone to do it I'd probably be looking at a multi-decade ROI, plus we'd have to hire someone to occasionally manage/fix the switching hardware if I didn't know how to do it myself. (I would've loved to have gone the DSLAM route, but our phone junction box was outdoors with no room to add a DSLAM, much less multiple drops from multiple ISPs. So we partitioned a janitor's closet to make a "server closet" and pulled all the ethernet to there. We got lucky in that there was a crawlspace along the top front of the building where the electrical lines for the businesses signs run. I installed the conduit there, but it was not fun going through 1/8 mile of crawlspace on my hands and knees multiple times.)

    For new buildings, I completely agree with you. Install conduit and ethernet from the get-go.

A business is just a group of people agreeing to work together as a group. So all business taxes end up being paid for by people anyway. Via lower wages for employees, higher prices for customers, and lower dividends for stockholders. This misguided notion of "fairness" for business taxes places taxes on a whack-a-mole target where it's easily dodged or shifted onto unintended targets (customers and low-level employees).

    We can't "run out" of helium. Anything which emits alpha particles creates helium. Alpha particles are just helium nuclei, and when they bump into other atoms and steal the electrons they become proper helium atoms. These reservoirs are just places were radioactive decay underground generated lots of helium, and the rate at which the rocks let helium pass through is slower than the rate at which new helium is being created.

    So unlike oil, this helium isn't just sitting there waiting to be tapped. It's slowly leaking out - it is one of if not the smallest molecule (smaller than H2) and can squeeze through just about anything. Even metal storage tanks will leak it. And once it reaches the air it's inevitably lost into space. The rate it's leaking out should be proportional to the amount of helium, so the most efficient use would actually be to deplete any known reservoirs, then scale back your use to match the rate at which the reservoir is being replenished. Think of the problem as how to maximize the amount of water you can put to use when your only storage tank has an unfixable leak at the bottom. The more water you try to store in the tank, the faster it leaks, and so the percentage of water you can actually use decreases.

    The market wants to fix it by adding more housing units but is prevented by laws prohibiting development. This causes prices to increase, which normally acts as an incentive for more development. Since the city doesn't want that, it caps rents. This doesn't make the problem go away though. All it does is shift the problem from one of price into one of availability - a lot more people want to live there than there is available housing. This results in a larger population of people wanting to live there but unable to. Which leads to more people wanting to visit. Which leads to more demand for short-term rentals like hotels and Airbnb.

The artists do their thing first - they get to design what the car's shape will be like and where all the main areas like seating, wheels, trunk, etc. will go. Then the engineers who make the essential components like the engine and transmission have to figure out how to install their components into the shape and layout predicated by the artist. The safety engineer comes dead last. He's given a weight budget of x kg of steel, and has to decide where to put it to make the vehicle pass government crash safety tests, while staying within the bounds of the artist's body design and avoiding other already-designed components like the engine.
