  1. Parícutin in Mexico is a cinder cone volcano that’s supposed to have blown itself out. How many of these super volcanoes empty their caldera and will never blow off like that again?

  2. The only way outside on Mars is inside a space suit. Sunlight won’t be part Martian evolution. People will live underground with pods on the surface containing food plantations.

  3. Tesla is already ahead on batteries and autonomous data. Their next battery is 500,000 miles. Perhaps 750K if used like that (abused) test car.

  4. Could there be a puff ball planet or maybe a massive k next causing gravity lensing.

  5. Why do we ignore the latest ultra safe low cost nuclear power options that DO NOT create waste that’s dangerous for 300,000 years? Why do we persist with white elephant power plants? Such as French Flamanville and U.K. Hinkley Point. Potentially dangerous high pressure reactors made safe at massive cost. AND their waste is dangerous for 300,000 years. Regardless of global warming it is ridiculous that we actively hold back new energy technology. Especially when it’s zero CO2 and safer than even the safest energy source we have.

  6. Nuclear power can manufacture ammonia with zero CO2. Ammonia can fuel engines. Why are we not doing this?

  7. A man with cancer recently had a total recovery after infection with COVID-19. It seems the virus woke up his immune system which killed his tumours. For the rest of us enough vitamin D is highly important. The official dose is adequate for bone health. It’s not enough for a properly working immune system. Check it out.

  8. People complain about Starlink sats the size of a table. Something miles across would be a massive blot on the skyscape. Not to mention the reflected messing with nighttime temperatures. None of it could be recycled at end of life. Not to mention the rocket fuel to put it up there.

  9. Search for Ian Scott (Moltex) and Ed Pheil (Elysium) on You Tube. You may be very surprised. Moltex and Elysium have fast spectrum reactors that use a liquid fuel in the form of molten salt. Being fast spectrum there is no carbon moderator. They are fully engineered to burn irradiated used nuke fuel. The old PWR, CANDU and British AGR all use solid fuel pellets encased in metal tubes. The nuclear reaction releases gasses like caesium, iodine and noble gasses. By the time about 4% of the fuel's energy has been used, the internal pressure is so huge they have to be taken out and stored in deep water pools. Moltex and Elysium have a simple chemical process that converts the fuel pellets into salts. Don't confuse with reprocessing which is highly complex and very expensive. These used fuel salts are then put into a fast spectrum reactor and burnt. Its a liquid fuel so expansion is no issue. The gasses like iodine and caesium just become a salt within the salt fuel so there is no gas to leak. The noble gasses have a short half life so get separated and stored for a few weeks until they lose their radioactivity. These reactors (like all molten salts) are intrinsically safe. If they overheat the reaction slows down. If they cool the reaction speeds up. Safety shut down systems are required by law but the power output is fully self balancing. They burn down the used nuclear fuel until just 1% remains. The half life drops from 30,000 years to 30 years. These plants can also burn age expired plutonium bomb cores. The chemical fuel process mixes the plutonium isotopes making a goo that useless for bombs but works great in a fast spectrum reactor.  But what about all the depleted uranium? There is 200x of the stuff per every U235 that went into nuke fuel. Ed Pheil of Elysium says he can also burn that. Moltex probably could - but regulations etc. These plants are not in use is entirely, because the regulatory processes move at a glacial pace. Moltex are the farthest ahead with a plant expected to be on line in Canada burning CANDU irradiated fuel.  USA has completely rewrite is regulations as they were written for PWRs and are useless for anything else. UK has a back to basics regulator thats notoriously opaque and glacially slow. Canada works at a reasonable pace with open demands. France? It wasn't invented in France.

  10. Other than fish all vertebrates have the same form. Four limbs each with one bone, two bones, many bones. What happened to kill all the other formats?

  11. LiFePo4 batteries are already available for car and bike starter batteries. They are solid state so likely what Dyson is using. Agree on the name. Dyson does the high value stuff in U.K. Manufacturing is comparatively low skilled.

  12. If we really want to stop creating CO2 there is only one option. Like it or not nuclear is clean, safe and zero CO2. With companies like Moltex, Thorcon and Flibe the plants would be cheaper to build than coal and hugely cheaper to fuel and operate. They are of course being held back. The Left (who want climate change stopped via a socialist world government) do not want a solution because it crimps their plans for world domination. The Right who support the status quo want us to continue burning oil and coal. They lose if we go nuke.

  13. Kirk Sorensen was a NASA engineer tasked with providing power for a moon base. Solar was useless because the lunar night lasts 14 days. Batteries won’t help too heavy. He rediscovered the Oak Ridge molten salt reactor experiment (MSRE). It would work in low or even zero gravity. Runs at high temperature (smaller) and would be launched with new fuel which is not highly radioactive. There are problems (as always) but not the stuff you’d expect. Check out his videos.

  14. Joe Scott. Please get Ian Scot (presumably no relation) to explain how his Moltex Waste burner plant works. He’s on Titans of Nuclear. His plant in Canada is fully engineered and ready for construction. It’s expected on line by 2020. That’s really fast by nuke standards. The plant runs in the fast spectrum burning high level irradiated fuel from a PWR next door.

  15. The nastiness of nuclear bombs was seriously played up by all governments. They wanted the populace to be scared so they'd support a huge military to keep them safe. Im not suggesting nukes are nice but governments really over played their hands. They also used power plants to make bomb fuel (UK's Magnox for example). Then they chose inherently risky power plant designs that cost a fortune and go pop even few years. It's no surprise that nuke power has a bad press. Some environmentalists want to use energy scarcity to force central control of all energy use. They don't say so but that sounds a lot like communism. It failed last time and however it's packaged will fail again.

  17. My (version of) god is better than your god. Prove I am wrong. It’s impossible to prove that something does not exist. Science says here’s an idea. Prove it’s correct. When the evidence stacks up we can say we better understand the issue.

  18. Huge deposits of oil and gas were confirmed around 2010. Four years later, Putin annexed Crimea but did nothing about the oil deposits. He then fomented a civil war in the Eastern areas where yet more oil and gas has ben found. He's now tried to invade the whole country but he's stalled (or maybe just stopped) over the oil resource areas. Ukraine has existing oil and gas pipelines into Europe. Putin wants them to continue carrying Russian oil/gas at prices set by Putin. So he's invaded, flattened the cities, smashed the infrastructure and stolen the people to work in Russia. He has no intention of restoring the country. It's all about a gangster taking out a potential new competitor. That oil will stay in the ground until Putin's forces are fully thrown out.

  20. We have the energy solution in fast spectrum molten salt reactors. They extract 99% of the energy vs just 4% in today’s plants. They happily burn existing high level waste leaving short life easily managed materials. Cost to build is cheaper than gas or coal so they’ll put both out of business solving the global warming problems.

  23. The Medieval Warm Period AD 900 to AD 1300 was 2 degrees C above average. It was followed by the “Little Ice Age” AD 1350 to AD 1900 which was 2 degrees C below average and during Maunder Minimum even colder. We are currently comparing our temperature to 1870 which was 0.3 below average. We are now 0.5 degrees above 1870. So we are warming but we are still recovering from an extended cool period. And we are only just a touch above average. Question what caused the 400 years of medieval warm followed by 500 years of cool. These numbers are not explained and some even want to pretend the medieval warm never happened.

  24. Sorenson made the point that many transuranics are very useful so chemical processing is needed. He's also points out that the chemical processes are easy to do in spite of them being radioactively hot. Carbon is used in the British AGR solid fuelled gas cooled rectors. These run with steam conditions of 565 degs C so the gas (and carbon) has to be a lot hotter. The graphite core is there for the life of the reactor. This http://www.formatex.info/energymaterialsbook/book/761-768.pdf suggests a beryllium liquid moderator instead of graphite.

  25. Sadly there are so many rigid opinions Solar = good Nukes = bad. Explain molten salt and thorium to an anti nuke protestor and they wont listen. Explain it to a traditional nuke engine and all they can think is how its not what they are used to. A presenter from Atkins (different vid) said it would be at least 50 years before thorium comes on stream. Why so long?

  26. The Sheerness munitions will blow upwards. Damage will be caused by falling debris and tidal wave. But don’t worry, the insurance industry will be fine. The small print always excludes acts of war.

  27. The really hard part is finding somewhere with two lakes separated by a big drop. It's also pretty rough on the fish. UK has one but there are no other sites that can do the job.

  28. Would the fuel cell membrane stop proton more easily than a electrons? I mean, one Proton is >1800 times more massive than one electron.

  29. One of the many problems with PWRs is that radioactive Iodine and Caesium are both released in gaseous forms and both are toxic to life. A molten salt reactor cannot do this as the Iodine and Caesium will produce their own salt within the reactor core.

  31. When everyone has an autonomous car the market will be rammed full many times over. I suspect many will simply not let their cars out as the return won’t be worth the costs. (Insurance etc).

  33. Pulling carbon from the atmosphere is all very well when it rally does contain too much CO2. However, what if the climate models are wrong and what if the planet is doing fine just as it is?

  34. Don’t forget the disruption S curve. Capturing 50% of the market takes as long as the first 2%. Tesla has just passed the magic 2% and their tech is at least 5 years ahead of Big Auto.

  35. Xenon is a rare gas unless you have a nuclear reactor that allows it to escape from the fuel. Molten salts are ideal as the gas just bubbles out. The short 1/2 life quickly decays and to have one of the stable isotopes.

  36. 4th Gen nuclear (molten salts) will be super low cost and super safe and zero CO2 and low waste. What’s not to like? When they are cheaper than coal, there won’t be a point to burning it.

  37. Thorium will only work in liquid fuelled reactor. It's a waste of time in solid fuel plant and why it was dropped when they were making solid fuel for bombs.

  42. My complaint about wind turbines is the 20% performance factor. That 100% capital cost is sat there 100% of the time but only doing useful stuff for 1/5 of the time. All those finite elements (especially copper) are sat there doing nothing for most of the time.

  43. Moltex energy are using the same hot salt technology found in Solar Thermal power to follow the fluctuating load from renewables. They use the reactor to heat the thermal stores. Stored heat raises steam for turbines. More importantly, they burn high level spent nuclear fuel. The stuff they release has a half life of 30 years (easily managed) against 30,000 years with the current nuclear plants. Moltex are building a plant in Canada with plans to be making electricity by 2028. No new mining, zero CO2 and very low waste. The waste it does make is easily managed. Elysium has similar plans. They will clean up high level nuclear waste, dispose of nuclear bomb cores and they can even use the depleted uranium we have left over from making the bombs. No new fuel has to be mined and a considerable waste storage problem is solved.

  45. Fusion will never be cheap and it’s also radioactive. Waste nuke reactor fuel only happens because PWRs cannot extract more than 4% of the fissile energy. Fast spectrum reactors like Moltex Waste Burner can extract 95 of the remaining 96%. The waste has a 1/2 life of 30 years vs 30,000 years for PWR used fuel. It’s intrinsically safe works at atmospheric pressure and cannot overheat even if the load (cooling) disconnected at full power.

  46. If the tube is evacuated why does it need an aerodynamic nose and tail? The issue will be slowing down. There’s a lot of kinetic energy to remove and no air to absorb the heat. Passenger comfort? You will get pushed against seatbelts while accelerating or while decelerating. People won’t much like that.

  47. Earth moves at something like 65,000mph around the sun. To get to the sun you have to drop most of that speed by flying the opposite way. Huge amount of fuel needed.

  49. The Shuttle was a great idea but the actuality was an engineered bodge. The solid boosters were sort of reused but many parts got scrapped. They are also horribly polluting. The fuel tank was scrapped on every flight. The orbiter was so untrustworthy, that it had to be pretty much rebuilt after every flight.

  50. Charles Okonkwo Nuclear waste is microscopic compared to the waste created by all other options including renewables. But Moltex Energy are building a plant that will be fuelled by high level nuclear waste. Instead of using just 3% of the available energy, Moltex will extract 99%. That means 30x less waste and what they do create has a 30 year 1/2 life instead of a 30,000 year 1/2 life.
