Toyota Unveils ‘Game Changer’ Hydrogen-Powered Car!

The Toyota Mirai (From mirai (未来), Japanese for “future”) is a hydrogen fuel cell vehicle, one of the first hydrogen fuel-cell vehicles to be sold commercially.

Under the United States Environmental Protection Agency (EPA) cycle, the 2016 model year Mirai has a total range of 502 km (312 mi) on a full tank, with a combined city/highway fuel economy rating of 66 mpg-US (3.6 L/100 km; 79 mpg-imp) equivalent(MPG-equivalent), making the Mirai the most fuel efficient hydrogen fuel cell vehicle rated by the EPA, and the one with the largest range.

Q&A: Could laser propulsion or microwave propulsion be the next big thing like the combustion engine?

Question by Paulita: Could laser propulsion or microwave propulsion be the next big thing like the combustion engine?
When the technology gets better could laser propulsion or microwave propulsion be the next big thing like the combustion engine ?

Quote I’m saying it is energy problem why laser propulsion and microwave propulsion is scfi and no one is working on it. How does a craft hold that much energy? Well I guess craft could burn a fuel and use that to to heat up the laser or microwave . Quote

What is he saying? What are the engineering problems making this scfi .

May be in 50 years from now or 100 years from now when the technology gets better NASA will be using laser propulsion or microwave propulsion .

You should realize that those ideas incorporate an external power source–lasers or microwave antennas on a fixed location like the Moon or an asteroid. Beams from them would hit a space vehicle and propel it out from the solar system.
Ion discharge engines offer good efficiency for the fuel on board. But thrust level is low, so the duration of the firing must be very long.

How does the ion propulsion engine work?

Question by Bobbi: How does the ion propulsion engine work?
i really need to know how it completely works but in a way i could easily explain it.

Best answer:

Answer by panic mode
it blasts ions. ions are produced and accelerated using high voltage. electric power needed this could for example be obtained from solar panels or nuclear device

Q&A: How can I Iaunch a lightweight (under 1lb) cylindrical object 1200ft in the air WITHOUT a combustible engine?

Question by sintheticmedia: How can I Iaunch a lightweight (under 1lb) cylindrical object 1200ft in the air WITHOUT a combustible engine?
Hello all,

I need to get a small electronic device (gathers weather data) into the air 1200+ ft and then have it slowly parachute down to collect data. A weather balloon won’t work because it is too slow moving as it ascends and will deviate its path based on wind/rain conditions. It can’t have a small rocket engine (no ordinates allowed) and would preferably not need a person to man it, i.e. an RC plane/helicopter would need a pilot on the ground. I am running out of options and hoped some people with more experience could offer up some suggestions. Any ideas are much appreciated! Thank you!
Edit–
Thank you all for the feedback, currently we are using compressed air, and it is indeed hooked up to a gun however this was never it’s intended use. I believe we are using 300 psi (a typical divers tank) and that won’t get it to the height we need. I can design the housing as a basic bullet to hold the payload, but I don’t think the guns components are rated to anything over what a divers tank can put out. Magnetic does sound expensive, but it is worth looking into. I also am reading up on the hyrogen pop bottle rocket. Again, thank you all for the replies, if all else failsI’ll grab some pop rocks and mountain dew!!!

what does the typical car engine block made up of? Does it show property of magnetism?

Question by redbulls: what does the typical car engine block made up of? Does it show property of magnetism?
Like aluminum, iron, magnesium. Percentage of composition would be better.
Does it show magnetic properties in the presence of magnetic field?

Best answer:

Answer by tlbs101
Older engine blocks (before the early 1980s) in general were made of cast iron. Today, almost all engine blocks are made of cast aluminum. Aluminum does not have any magnetic characteristics — Iron does. Some of the attached parts to an aluminum block may have magnetic properties.

If you apply a moving magnet to any metal conductor it will generate eddy currents in the metal and those eddy currents will produce a magnetic force of their own.
