I don't think it'll necessarily put cabbies out of work, because unless i'm mistaken the primary reason people would take a taxi other than drinking, is either they lack a car (by choice, or a family with only one car, where the wife or husband needs to get somewhere while the car is out), or there is no parking at the destination. It would seem that autonomous cars wouldn't benefit people in either of these cases.
The tech to do so is already out there. SASOL which is a south african petroleum products company, has gas to liquids plants that can produce gasoline and diesel products from methane. All you need to do is feed the methane from landfills and sewage plants to these gas to liquids plants, and you have gasoline equivalents from human excrement. The key to this technology is finding a cheap plentiful source of gas and high gasoline and diesel prices.
I believe the intention wasn't that africans wouldnt repair the machine. rather that you wouldnt need to rebuild the computerised combustion control system which is probably environmentally sealed. which seems accurate. Am I wrong on that point?
wood tar can be captured and gasified if the non gasified portion is caoturedb in a filter medium made of fuel and cycled back into the gasifier. part of your fuel then becomes the filter.
you would have to sort your trash into foodscraps and plastics as burning plastics could be harmful without catalytic converts and percipitators. and the cost of the control systems wouldnt scale. what would make more sense is the use of one of these units in a neighborhood where people drop off sorted foodscraps into a solar dryer to bleed off energy robbing moisture and are paid an energy credit. sort of like can deposit machines. this would amoratize the cost of the unit over the neighborhood and allow the economics of scale to still be realized. I'm sure a neighborhood could generate the 2000 pounds of foodscraps a day needed to keep this machine running.
Not quite. the innovations are in the control systems. that is what they have patents for. also standard gasification tech tends to convert the biomass to ash. this machine converts it into charcoal which both creates fertilizer and locks a portion of the carbon away mostly creating hydrogen and co. which are combusted into water and co2. the control over the combustion process that allows charcoal production over ash production is imporant as gasifier ash shakedown to make room for more fuel is the biggest problem keeping gasifiers from being used in diy stationary power generation. This tech they have developed dodges this problem.
I think you're mistaken as all powerplants are judged by this metric. Dollars per watt is the cost to add x amount of generating capacity to your grid.
Wouldn't it make just as much sense to have on hire designated drivers with a chase car to drive the designated driver back to the bar, free with x amount of total drinks for the group? That way you can atleast get some jobs out of the deal.
The solution to this problem, is to get all people who buy a self driving car to sign an EULA saying that there is a manual override function and they must pay full attention at all times in case of an accident. If the car senses an impending accident it immediatley returns control to the driver. All responsibilities resolved.
People who are riding in a 2 ton hunk of metal being propelled by explosive fuel should pay attention to the road and the situations around them even if the car drive itself.
Or you could start very small by making a special self driving car only lanes with an increased speed limit and car to car communication on the highways. Similar to the HOV lanes in California. Car hands over controlls if you ever purposefully leave the lane or have to exit the highway. Cars could draft eachother to negate the fuel economy penalty of the higher speed, and safely.
What about traction control, antilock brakes, fuel injection, catalytic converters, backup cameras, air ride suspension, heated windows mirrors and seats, collision avoidance, collision detection, airbags, automatic parallel park, and such?
More storage capacity beyond peak hours probably isn't profitable. You want to sell electricity during peak because that's when you're getting the highest dollar value for your power. They probably designed the salt storage, so the total output of the plant was extended long enough to generate during those peak evening hours, and no longer, so baseload power takes over. The smaller your storage is, the less power you would put into storage and the more power you put into spinning your turbine.
Solar panels do not exclusively operate in the infrared spectrum, so i'd be willing to venture a guess that carnot's law doesn't' apply to photovoltaics, but would apply to solar thermal.
As far as storing CO2 from mobile sources, the best proposal i've seen for this comes from the idea of sequestering CO2 in the arctic where, during the coldest points of the year, the air temperature is close to the temperature needed to produce CO2 snow. Which could then be dumped into an insulated pit, refrigerated, and buried. Antarctica also provides a large source of nearby power in the form of downhill winds near the coast which can develop to hurricane force, probably allowing wind turbines to power the entire operation. The proposal I read purported to be able to freeze out 1B tons of CO2 per year.
Korea has a national internet ID which is used as a verification step in almost all online account creation. You could allow anonymous posting or pseudonym posting if the user is willing to apply for an internet id. And limit it to one account per forum. If that account is doing abusive or illegal things a course of action is available and the identity could be subpeonad. Problem.here is slippery slope. Eventually the government would probably require all internet users to register like south korea.
wikipedia says c/5 optimal up to 2c. If we assume c for acceleration a 60kwh battery pack would kick out 80hp. 2c would give 160. Not terrible.... but a paralell super capacitor would likely solve high battery drain and increase acceleration. super caps can kick out a few thousand c so you would only need a small one.
Well it's simple enough to just redesign the roach motel so it baits them with wheat or something, i'd imagine. But part of me wonders if we would be better off just building a mega roach hotel chocked full of actual food in a neighborhood and instead of killing the roaches with glue, just relocating them into the forest when the roach hotel reaches capacity, or using them as feed for fish or something.
well a 7wh battery charged in 20 seconds would be 1.2 kw and 30 seconds would be 800 watts. the charger would be pricey but if you are willing to lengthen that to five minutes which still isn't bad you could get away with eighty watts which is pretty normal.
No, in all seriousness i'm merely pointing out that the original posters assertion as perceived by me, that it was incredibly rare for mechanical devices to survive 9 years without maintenance, is not necessarily the case. Plenty of washers, dryers, cars, and things like servos, industrial machines etc... may not receive maintenance for a LONG time and still continue to function as designed. A good example would be Russian nuclear lighthouses, which are hundreds of miles from the nearest person and did their job admirably with little in the way of maintenance, in similarly cold environments.
I'm pretty sure it would be easier and cheaper to raise animals and let them do their thing until they perish from natural causes than this and probably a higher quality of meat would result.
This may sound absurd,but I wonder if you would get enough power by wrapping the rims and frame in high efficency thin film solar panels. Or you could include a solar hat as an accessory. It would likely generate more than enough power to allow for perpetual usage in sunlight. And would likely extend battery life in indoor level conditions.
Generally most hydrogen is produced from breaking down natural gas. So this won't really impact rocket fuel until it can get hydrogen produced by electrolysis below that of natural gas. With the glut from fracking, I don't see this happening, as alot of our energy now is generated from natural gas. Generating energy from natural gas to use it to split water is likely not as efficient as stripping off the hydrogen directly.
Floating point operations, and floating point operations per second would have similar looking spellings FLOPs and flops
Like if you wanted to say 2 gigaflops, 2 billion floating point operations And 2 gigaflops for 2 billion floating operations per second
Perhaps you could differentiate them by just dropping normal pluralization conventions? Like 2 gigaflop for 2 billion floating point operations, and 2 gigaflops for 2 billion floating point operations per second/
