.that bit should be hot you can run a mechanical pump on the engine but it only pumps when the engine's running I quite like to get the cooling going before there's any heat around so I've got a very small electrical pump in the seacock over there but I've got the water flowing and I will now check everything is off to start with I've got some pressure I shall turn the gas on at the source I've got a bit of crosswind at the moment so my little lighter might get blown out.
But I shall try and get a flame oh, I've got a flame eh, that was well behaved sometimes they go pop have I got a flame I think I've got a flame But I can't see anything. it's ignited this one is usually the one that misbehaves and it pops like that I've got a flame. Hooray! And that just acts as a cooker, does it Yes, it is a gas hob I've got three of them and, um life is less busy if you've only got one of them.
Plants vs Solar Panels Which is better at capturing solar energy AtBristol Science Centre
This is an aquatic plant called pondweed, and we can see that it's making tiny bubbles of gas. This gas is oxygen and all plants produce it in a process called photosynthesis. The word photosynthesis comes from the Greek meaning light' and putting together'. Plants use the energy in sunlight to make sugars, out of the simple ingredients of carbon dioxide and water. And do you remember those bubbles of gas we saw earlier Well. deep breath they're pretty useful. To make the sugar, or glucose, the bonds which hold the molecules together.
Have to be broken apart and rearranged. The bonds are made of electrons. So the water needs to lose electrons, and the carbon dioxide has to gain electrons. And the colour of leaves gives us a clue to what is responsible for this rearrangement of electrons. Every leaf cell contains a pigment called chlorophyll'. It's the chlorophyll which makes the leaves green and helps make photosynthesis happen. Chlorophyll has the amazing ability to release electrons when exposed to sunlight. The electrons from the chlorophyll are replaced by splitting apart water into ions of hydrogen and oxygen.
The excess oxygen is then released into the air. The flow of electrons from the chlorophyll is then used with the remaining hydrogen ions to produce the energy needed to synthesise glucose from molecules of carbon dioxide. So sunlight provides the energy we need to move electrons from one molecule to another turning light energy into chemical energy ready for our plant to use. But can we do the same thing artificially How does photosynthesis compare to a solar panel Well, solar panels like those on the Energy Tree.
Use light as an energy source, and they also generate a flow of electrons. But they don't store chemical energy they convert light energy into electrical energy. They do this by using something called the photoelectric effect'. When photons come and hit a metal surface, they knock off electrons. We then capture and store these electrons. These photovoltaic cells are made of a silicon crystal. But silicon is a poor conductor of electricity. So impurities are added to help. This creates something called a 'semiconductor'. As light hits the surface, electrons are knocked loose.
The electrons then flow from areas with a high concentration, to areas with a low concentration. It's this flow of electrons which generates an electric current. We've done this on a big scale on our roof. We have 560 square metres of solar panels, which generate 47,000 kilowatt hours of electricity per year. So which is better, leaves or solar panels How efficient is each system at transforming the energy from sunlight Well, a leaf can turn only three percent of light energy hitting its surface into chemical energy through photosynthesis.
Whereas, a solar panel of the same area can turn roughly ten percent of the light energy into electrical energy that's over three times more efficient! But it's not quite as simple as that. There's all sorts of other things to take into account as well. Such as the time of day, the location, types of plant, and transport and storage costs on the other side as well. Solar panels may be able to absorb more wavelengths of light than leaves, but leaves can grow and repair when damaged. The Energy Tree may be able to charge your phone,.
STIRLING ENGINE KANNADA 38MB
This is very very important stirling engine and this one has been designed by subir bhaduri. you can see there is a little wooden stand, and these are the various parts of the stirling engine. this is the box stand on which this engine will be mounted. you can see a vertical screw and on this screw you screw in the nut on which there is a heat sink. this heat sink has got a central bore. right side is where you will put in the lamp. and then you take.
The flywheel and crank rod and you screw it in the heat sink. this is the crank part. then you take a connecting rod and screw it to the crank and you just let it hang around. then you take the long piston and there is a small displacer which is made from mseal. you put this long tube in the bore of the heat sink. then lift the crank rod and put it in the displacer. we need another crank. there is another crank which is phased out at 90 degrees and now you connect the crank rod to the long tube. finally you take the.
Flywheel and tighten the screw of the flywheel to the axle so it is solidly connected to it. now the stirling engine is almost assembled. you have got to ensure that the displacer and the piston rotate smoothly. you need to oil them. finally take a spirit lamp and heat the right rod. red part is actually ceramic to insulate. then you kick start the flywheel and you will be surprised that this engine keeps rotating. it will keep rotating till the fuel lasts. its a heat engine and quite a beauty to behold. you can see the con rods,.
SOLAR TOY CAR ENGLISH 14 MB.wmv
This solar toy car is a ready made chinese toy. it is difficult to make it because it is difficult to find small solar panels. but it is a very nice toy. you can see these 4 wheels down below. these actually do not do much. it is actually powered by this middle wheel.this middle wheel is driven by a motor which runs on solar panels. if you put it on a board out in the sun, the car strikes the boundary and then turns and moves on. if you place your hand on top of the car, sunlight is cut and stops producing electricity.
Motor de Stirling corto Stirling engine short
The Stirling engine is a device that converts heat into work by means of a set ot thermodynamics processes, named Stirling cycle, performed by a fluid The working fluid is air enclosed in a glass test tube placed on a support. The tube contains inside seven marbles which can move along the tube The open end is closed by a plug which has a hole through which a flexible tube is connected The flexible tube is also connected to the top of a vertically arranged glass syringe whose upper part can be displaced over the bottom.
The heat energy is supplied to the air by heating the closed end of the glass tube The Stirling cycle consists of four stages heating, expanding, cooling and compression First stage The initially colder air is heated maintaining constant its volume, and its pressure increases Second stage The pressure increase pushes the balls towards the colder opposite end of the tube, resulting in an isothermal expansion of the air Third stage The air volume increase forces the top of the syringe to move upward. The cold end upwards around the supporting point. The balls move back to the tube hot end, cooling the air which decreases its pressure at constant volume.
Berry Petroleum COO Michael Duginski at GlassPoints Solar EOR Project Commissioning
Hello, my name is Michael Duginski, and I'm with Berry Petroleum, we want to welcome everyone here to our oilfield today. I appreciate the comments that Rod made. I saw in the news or the email flyer that was coming out that it was being hosted by a major California oil company and I'm really of the view that Kevin described us and we are a small independent here in in California. The interesting thing about Berry Petroleum is that we've been around since 1909. So we've been operating in the state for a hundred years.
We've seen a lot of things in the San Joaquin Valley and as the previous speakers have said, the easy oil has been discovered. We don't anticipate a large oilfield like the Midway Sunset field or the Belridge field being discovered any time soon. So where we're at now is that we really need to apply new technology to develop the remaining resource. We're a growing business in California. California oil business, in my opinion and in Berry's opinion is not a shrinking business. We are making our largest capital investment that we have ever made in the.
State this year. uh. and we continue to grow And we continue to grow our production and we continue to employ more people and invest more money in the state. Now, we currently apply relatively sophisticated technologies in the oil field to maximize the value of our assets. We generate over 100 MW of power from cogeneration which as a byproduct produces steam for our operation, and the whole reason that we got into the power business was not because we want to be a power producer, but because we want.
Low cost steam for our oil production. We use 3D seismic to identify drilling targets, we use satellite imagery to monitor where our steam injection goes in our steam floods, we use a tremendous amount of horizontal drilling to maximize our recovery so we see ourselves as a technology company, but we're too small to develop those technologies ourselves. We don't have the money to have a research lab, we don't have the staff to have a research lab. And that's where partnering with Glasspoint really makes sense for us. We provided the oil field and the infrastructure,.
Glasspoint provided this new technology. We commend Glasspoint for believing enough in their technology to make the investment in this project themselves to prove both their concept of design and also what the economics are. were interested in solar steam generation because any new innovative technology that lowers our costs, as we've been discussing lowers the economic limit of the oil field, maximizes our oil reserves and our production. if this technology is successful it will translate into important business opportunity for Glasspoint and for the other oil and gas producers in the state of California.
